LATS MULTI V PIPING

DESIGN SOFTWARE

The proper design and installation of the refrigerant piping system is a critical element of a Multi V system. Multi V Heat Pump systems require two pipes between components – a liquid line and a vapor line. Multi V Heat Recovery systems require three pipes between the outdoor unit and the heat recovery unit – a liquid line, a low-pressure vapor line, and a high-pressure vapor line. A properly designed refrigerant piping system ensures that refrigerant is delivered to the indoor unit coils for optimal system performance and capacity.

LG Air Conditioner Technical Solution (LATS) software is a total design solution for LG Multi V air conditioning systems. This

Windows

®

-based application assists the design engineer with specifying and sizing outdoor and indoor units (by calculating component capacity based on design conditions), laying out the refrigeration distribution pipe system, checking piping limitations, calculating refrigerant charge, and generating equipment schedules and piping diagrams in (.dxf) format for use on CAD building design drawings.*

* Windows ® is a registered mark of Microsoft ® Corporation.

To ensure that the refrigerant piping design meets LG’s quality standards, a LATS refrigerant piping design must be provided with every Multi V order. Following the installation, if any changes or variations to the design are necessary, a new LATS file must be created and provided to LG prior to system commissioning to ensure the proper pipe size has not changed.

Design Choices

LATS Multi V software is flexible, offering the HVAC system engineer an easy to use Tree mode.

Tree Mode

Using the Tree mode, the engineer can quickly create a one-line schematic drawing of a Multi V system. Integration of the engineered pipe system into the building drawings is done at a later date by the draftsperson using standard drafting software tools.

• Import building loads from an external file (.xls format).

• System components selected using an easy drag and drop process.

• Automatically analyzes and checks the design complies with most piping design limitations.

• Sizes refrigerant piping.

• Generates a system engineering report (.xls format).

• Generates an equipment schedule (.xls or .dxf format).

• Generates a system piping diagram (.dxf format).

Figure 1: Screenshot of LATS Pipe System Design Tool in Tree Mode.

LATS Report

LATS Multi V software generates a report file (.xls format) containing project design parameters, cooling and heating design day system component performance, and capacity data. The report calculates the system combination ratio, calculates the system refrigerant charge, and provides detailed bill of material information including a list of Multi V outdoor units, air handlers, control devices, accessories, refrigerant pipe sizes segregated by building, by system, by pipe size, and by pipe segments.

Casing

The case is designed to mount concealed above a finished ceiling.

Fan supply air is front horizontal with a dedicated rear horizontal return. The unit is manufactured with coated metal. Cold surfaces are covered with a coated polystyrene insulating material. The cold surface areas of the case are covered externally with sheet insulation made of Ethylene Propylene Diene Monomer (M-Class) (EPDM) conforming to ASTM Standard D-1418. The case is provided with hanger brackets designed to support the unit weight on four corners.

Hanger brackets have pre-punched holes designed to accept field supplied, all-thread rod hangers.

Fan Assembly and Control

The unit has Sirocco fans made of high strength ABS GP-2200 polymeric resin. Fans are directly driven and mounted on a common shaft. The fan motor is a Brushless Digitally Controlled (BLDC) design with permanently lubricated and sealed ball bearings. The fan motor includes thermal, overcurrent and low RPM protection.

The fan / motor assembly is mounted on vibration attenuating rubber grommets. The fan impeller is statically and dynamically balanced.

The fan speed is controlled using a microprocessor based, direct digital control algorithm that provides a high fan speed in cooling thermal ON and low fan speed in cooling thermal OFF, high fan speed in heating thermal ON and fan off in heating thermal OFF. The fan speeds can be field adjusted between low, medium, and high speeds and DIP switch settings will allow the fan to run constantly during defrost or oil return modes. Each setting can be field adjusted from the factory setting (RPM / ESP) to compensate for additional resistance to airflow caused by field connected ductwork or other airflow restricting devices.

In Heating mode, the microprocessor control will activate the indoor unit when indoor room temperature falls below setpoint temperature and signals the outdoor unit to begin heating cycle. The indoor unit fan operation is delayed until coil pipe temperature reaches 76ºF.

Significant airflow is generated when pipe temperature reaches 80°F.

In lieu of factory return air thermistor, screw terminals on the microprocessor circuit board accommodate various models of wall-mounted local controllers and/or a wall-mounted remote temperature sensor. The unit microprocessor is capable of accepting space temperature readings concurrently or individually from either:

1. Wall-mounted wired controller(s)

2. Factory mounted return air thermistor or the optional wall-

mounted wired remote temperature sensor

A single indoor unit has the capability of being controlled by up to two local wired controllers. The microprocessor controls space temperature using the value provided by the temperature sensor sensing a space temperature that is farthest away from the temperature set-point. The microprocessor control provides a cooling or heating mode test cycle that operates the unit for 18 minutes without regard to the space temperature. If the system is provided with an optional wall-mounted local or central controller, displayed diagnostic codes are specific, alpha numeric, and provide the service technician with a reason for the code displayed.

Air Filter

Return air is filtered with a removable, washable filter with antifungal treatment. MERV 13 filter modules with plenums available.

Microprocessor Controls

The unit is provided with an integrated microprocessor-based controller. The controller is capable of performing functions necessary to operate the system without the use of a wall-mounted controller.

A temperature thermistor is factory-mounted in the return air stream.

All unit operation parameters, excluding the unit operating schedule, are stored in non-volatile memory resident on the unit microprocessor. Operating schedules are stored in select models of the optional, wall-mounted, local, or central controller. The field supplied communication cable between the indoor unit(s) and outdoor unit is to be a minimum of 18 AWG, 2-conductor, stranded, and shielded cable

(RS-485), terminated via screw terminals on the control boards.

The microprocessor control provides the following functions: auto addressing, self-diagnostics, auto restart following power restoration, test run, and will operate the indoor unit using one of five operating modes:

1. Auto Changeover (Heat Recovery only)

2. Heating

3. Cooling

4. Dry

5. Fan Only

For Heat Recovery systems the Auto Changeover setting automatically switches control of the indoor unit between cooling and heating modes based on space temperature conditions.

For Heat Pump systems, heated or cooled air delivery is dependent upon outdoor unit operating mode.

8 | HIGH STATIC

Condensate Lift/Pump

The indoor unit is provided with a factory installed and wired condensate lift/pump capable of providing a minimum 27.5 inch lift from the bottom exterior surface of the unit casing. The unit drain pan is provided with a secondary drain port/plug allowing the pan to be drained for service. The lift pump comes with a safety switch that will shut off indoor unit if condensate rises too high in the drain pan.

Condensate Drain Pan

The condensate drain pan is constructed of high impact polystyrene resin (HIPS).

Coil

The indoor unit coil is constructed with grooved design copper tubes with slit coil fins, two (2) to three (3) rows, nineteen (19) to twenty-one (21) fins per inch.

• Data is valid under diffuse field conditions.

• Data is valid under nominal operating conditions.

• Sound power level is measured using rated conditions, and tested in a reverberation room per ISO 3741 standards.

• Sound level will vary depending on a range of factors such as construction (acoustic absorption coefficient) of particular area in which the equipment is installed.

Casing

The case is a low profile design with a maximum height of eight inches designed to mount concealed above the finished ceiling. Fan supply air is front horizontal with a rear horizontal field convertible to a bottom return. The unit is manufactured with coated metal. Cold surfaces are covered with a polystyrene insulating material. The case is provided with hanger brackets designed to support the unit weight on four corners. Hanger brackets have pre-punched holes designed to accept field supplied all-thread rod hangers.


The unit has Sirocco fans made of high strength ABS HT-700 polymeric resin. Fans are directly driven and mounted on a common shaft. The fan motor is a Brushless Digitally-Controlled (BLDC) design with permanently lubricated and sealed ball bearings. The fan motor includes thermal, overcurrent and low RPM protection. The fan/motor assembly is mounted on vibration attenuating rubber grommets. The fan impeller is statically and dynamically balanced. The fan speed is controlled using a microprocessor based direct digital control algorithm that provides a high fan speed in cooling thermal ON and low fan speed in cooling thermal OFF, high fan speed in heating thermal ON and fan off in heating thermal OFF. The fan speeds can

E\¿HOGFRQQHFWHGGXFWZRUNRURWKHUDLUÀRZUHVWULFWLQJGHYLFHV

In Heating mode, the microprocessor control will activate the indoor unit when indoor room temperature falls below setpoint temperature and signals the outdoor unit to begin heating cycle. The indoor unit fan operation is delayed until coil pipe temperature reaches 76ºF. Significant airflow is generated when pipe temperature reaches 80°F. In lieu of factory return air thermistor, screw terminals on the microprocessor circuit board accommodate various models of wall-mounted local controllers and/or a wall-mounted remote temperature sensor.

The unit microprocessor is capable of accepting space temperature readings concurrently or individually from either:


2. Factory mounted return air thermistor or the optional wall-

mounted wired remote temperature sensor.

A single indoor unit has the capability of being controlled by up to two local wired controllers. The microprocessor controls space temperature using the value provided by the temperature sensor sensing a space temperature that is farthest away from the temperature set-point. The microprocessor control provides a cooling or heating mode test cycle that operates the unit for 18 minutes without regard to the space temperature. If the system is provided with an optional wall-mounted or central controller, displayed diagnostic codes are specific, alpha numeric, and provide the service technician with a reason for the code displayed.

Air Filter

Return air is filtered with a removable, washable filter with anti-fungal treatment.




All unit operation parameters, excluding the unit operating schedule, are stored in non-volatile memory resident on the unit microprocessor. Operating schedules are stored in select models of the optional, wall-mounted, local, or central controller. The field-supplied communication cable between the indoor unit(s) and outdoor unit is to be a minimum of 18 AWG, 2 conductor, stranded and shielded cable

(RS-485), terminated via screw terminals on the control boards.

The microprocessor control provides the following functions: auto addressing, self-diagnostics, auto restart following power restoration, test run, and will operate the indoor unit using one of five operating modes:


2. Heating

3. Cooling

4. Dry

5. Fan Only



66 | LOW STATIC


The indoor unit is provided with a factory installed and wired condensate lift/pump capable of providing a minimum 27.5 inch lift from the bottom exterior surface of the unit casing. The lift pump comes with a safety switch that will shut off indoor unit if condensate rises too high in the drain pan.



Coil

The indoor unit coil is constructed with grooved design copper tubes with slit coil fins, two (2) to three (3) rows, eighteen (18) to twenty-one (21) fins per inch.

DUCTED BUILT IN


Casing

The case is designed to mount concealed above a finished ceiling.

Supply air is front horizontal with a dedicated bottom vertical return.

The unit is manufactured with coated metal. Cold surfaces are covered with a coated polystyrene insulating material. The case is provided with hanger brackets designed to support the unit weight on four corners. Hanger brackets have pre-punched holes designed to accept field-supplied all-thread rod hangers.


The unit has Sirocco fans made of high strength ABS HR-2407 polymeric resin. Fans are directly driven and mounted on a common shaft. The fan motor is a Brushless Digitally-Controlled (BLDC) design with permanently lubricated and sealed ball bearings. The fan motor includes thermal, overcurrent and low RPM protection.

The fan/motor assembly is mounted on vibration attenuating rubber grommets. The fan impeller is statically and dynamically balanced.

The fan speed is controlled using a microprocessor based direct digital control algorithm that provides a high fan speed in cooling thermal ON and low fan speed in cooling thermal OFF, high fan speed in heating thermal ON and fan off in heating thermal OFF. The fan speeds can be field adjusted between low, medium, and high speeds and DIP switch settings will allow the fan to run constantly during defrost or oil return modes. Each setting can be field adjusted from the factory setting (RPM / ESP) to compensate for a limited amount of additional resistance to airflow caused by field connected ductwork or other airflow restricting devices.

In Heating mode, the microprocessor control will activate the indoor unit when indoor room temperature falls below set-point temperature and signals the outdoor unit to begin the heating cycle. The indoor unit fan operation is delayed until coil pipe temperature reaches 76ºF. Significant airflow is generated when pipe temperature reaches 80°F. In lieu of factory return air thermistor, screw terminals on the microprocessor circuit board accommodate various models of wall-mounted local controllers and/ or a wall-mounted remote temperature sensor. The unit microprocessor is capable of accepting space temperature readings concurrently or individually from either:


2. Factory mounted return air thermistor or the optional

wall-mounted wired remote temperature sensor

A single indoor unit has the capability of being controlled by up to two local wired controllers. The microprocessor controls space temperature using the value provided by the temperature sensor sensing a space temperature that is farthest away from the temperature set-point. The microprocessor control provides a cooling or heating mode test cycle that operates the unit for 18 minutes without regard to the space temperature. If the system is provided with an optional wall-mounted local or central controller, displayed diagnostic codes are specific, alpha numeric, and provide the service technician with a reason for the code displayed.

Ceiling Grille/Duct Kit

An optional flush-mounted ceiling return air grille and accordion-style canvas duct kit provides a short-ducted return air solution.

Air Filter

Return air is filtered with a removable, washable filter with anti-fungal treatment.


The indoor unit is provided with a factory installed and wired condensate/lift pump capable of providing a minimum 27.5 inch lift from the bottom exterior surface of the unit casing. The lift pump comes with a safety switch that will shut off indoor unit if condensate rises too high in the drain pan.

VERTICAL / HORIZONTAL AIR HANDLER


Casing

The unit is designed to operate in the vertical up flow configuration or horizontal left end supply air. Return air opening is on the bottom in the vertical position or right end in the horizontal position. Return air plenum sub-base is to be field-provided. The supply air connection is male flange. The unit case is made of 22-gauge coated metal and the external surfaces are finished with a high gloss baked enamel finish. Finish color is “morning fog” (medium beige). Cold surfaces are galvanized steel. The cold surfaces of the case are internally insulated with ½ inch foil faced, polystyrene fiber insulation.

The inside surface of the fan assembly door access panel is treated with ½ inch polystyrene fiber insulation, encapsulated on both sides, and sealed along the edges with a reinforced foil-faced covering to prevent deterioration caused by panel removal. All access panels are provided with gasket seals to minimize air leakage. The unit case is designed to accept an internal, optional, LG electric strip heater. The unit bears the ETL label. Unit breaker, fuses, and / or disconnect are provided by others.

temperature safety switch, and interconnecting control wiring harness with a quick connect plug for easy connection to the air handler control board. Auxiliary heat modules are available in nominal capacities of 5, 10, 15, and 20 kW at 230/60/1.

Heating elements are powered from a field provided separate power source. 5 and

10 kW modules are powered from a single power wire. The 15 and 20 kW modules are powered from two power wires.

Heating module breakers, fuses, and / or disconnects are to be field provided.

Electric Heat Module Controls

The electric heat module is capable of operating at full capacity during system defrost and oil return operations. When the air handler is operating in the Cooling, Dry, or Fan Only modes, the electric heater operation is locked out and unavailable. When the air handler is operating in the Heating mode, the heater is field selectable to operate when the room temperature is 2°F lower than set-point or manually if provided with a start/stop signal from a third-party outside source.


The indoor unit has an integral fan assembly consisting of a galvanized steel housing and a forward-curved fan wheel. The direct drive fan/motor assembly is mounted on rubber grommets isolating the rotating assembly from the fan housing. The fan motor is a

Brushless Digitally-Controlled design (BLDC), having permanently lubricated and sealed ball bearings. The fan motor includes thermal, overcurrent and low RPM protection. The fan/motor assembly is mounted on vibration attenuating rubber grommets. The fan impeller is statically and dynamically balanced. Fan speed is controlled using a microprocessor-based direct digital control algorithm that provides a minimum of a high fan speed in cooling thermal ON and low fan speed in cooling thermal OFF, high fan speed in heating thermal

ON and fan off in heating thermal OFF. The fan speeds can be field adjusted between low, medium, and high speeds and DIP switch settings will allow the fan to run constantly during defrost or oil return modes. Each setting can be field adjusted from the factory setting

(RPM/ESP). The setting provides delivery of the high speed air volume against an external static pressure of up to 1.0 in-wg.


The unit is equipped with an integrated microprocessor-based controller capable of performing functions necessary to operate the system without the use of a wall-mounted controller. A temperature thermistor is mounted in the return air stream. All unit operating parameters, excluding the operation schedule, are stored in non-volatile memory resident on the unit microprocessor. Operating schedules are stored in select models of the optional wall-mounted local or central controller. The field-supplied communication cable between the indoor unit(s) and outdoor unit is to be a minimum of 18 AWG,

2 conductor, stranded, and shielded (RS-485). The microprocessor control provides the following functions: auto addressing, self- diagnostics, auto restart following power restoration, and will operate the indoor unit using one of the following five operation modes:

Air Filter

The unit comes with a filter rack capable of accepting a field- provided 16” x 20” x 1” (NJ chassis) or 24” x 20” x 1” (NK chassis) filter cartridge.

The filter rack is equipped with guides that keep the filter centered in the rack. Filter service access is from the front of the unit without removing the coil or fan area access panels. Filter access door is provided with thumb screws that can be removed.

In Heating mode, the microprocessor control does not begin fan operation until coil pipe temperature reaches 76ºF. Significant airflow is generated when pipe temperature reaches 80°F. A field-selectable option maintains fan operation for 30 minutes following cooling cycle operations.

1. Wall-mounted wire controller

2. Factory-mounted return air thermistor or the optional wall-

mounted wired remote temperature sensor.

The microprocessor controls space temperature using the value provided by the temperature sensor sensing a space temperature that is farthest away from the temperature set-point. A single indoor unit has the capability of being controlled by up to two local wired controllers. The microprocessor control provides a cooling or heating mode test cycle that operates the unit for 18 minutes without regard to the space temperature. If the system is provided with an optional local or central controller, displayed diagnostic codes are specific and provide the service technician with the reason for the code displayed.

Handling Condensate

The drain pan is designed to work with a gravity building drain system. If condensate lifts/pumps are needed, they are to be field-provided. A secondary drain port plug is provided allowing the pan to be drained for service. Condensate float safety switch connections are available on the main control board for connection of a field supplied float safety switch.


The condensate drain pan is constructed of HIPS (high impact polystyrene resin).

Coil

The indoor unit coil is constructed with grooved design copper tubes with slit coil fins, 2 to 3 rows, 18 fins per inch.

General Mounting - Vertical / Horizontal Air Handler Units

Vertical / horizontal air handler units can be installed either in an upflow or a horizontal-left position.

General Guidelines

• Support platforms should be sturdy enough to support the air handler unit plus any accessories including filter boxes. The size of the support should be bigger than the air handler unit; the unit itself should be placed at the center of the support.

• Vibration isolators (field-supplied) must be installed between the air handler unit and the support(s).

• Upflow installation has to be applied if a return plenum and a supply duct are present.

• Secure the plenum to support adapters and duct work.

• To prevent air leaks, seal all ducts following local codes.

• Follow all relevant building codes in installations in which an external condensate pan may be necessary. Supports for air handler units should be located in or above the external condensate pan.

Specific Guidelines for Horizontal-Left Installation

• Units should not be installed where the access panels face up or down, nor where filter access is obstructed.

• If the air handler unit is suspended, use angled steel brackets with threaded rods as support.

Duct Work For Vertical / Horizontal Air Handler Units

• Use at least ten (10) M4-25L screws when attaching the supply duct to the vertical-horizontal air handler unit.

• To prevent vibration transmission, install flexible connectors between the supply duct and the vertical-horizontal air handler unit.

If an electrical heater is included, the flexible connector must be constructed from a heat-resistant material.

• When routed through unconditioned spaces, ducts must be insulated and covered with vapor barriers.

• Internal acoustical insulation lining may be necessary for a metal duct system if it does not have a 90° elbow and ten (10) feet of main duct to the first branch takeoff.

• Fibrous ducts could be used as a substitute if built and installed in accordance with the most recent edition of the Sheet Metal and

Air Conditioning Contractors’ National Association (SMACNA)

Construction Standard.

• Fibrous ducts and acoustical linings must follow National Fire

Protection Association (NFPA) Standards 90A or 90B as tested by

UL Standard 181 for Class 1 ducts.

• Seal around the ducts to prevent air leaks.

General Drain Piping Information

General Drain Piping Information

All ducted indoor units generate water during cooling operation, therefore, how to properly handle this condensation must be considered. Depending on the location of the indoor unit, condensation can be drained directly to the outside of the building, or a common indoor unit drainage piping system can be installed.

Ducted Unit Drain Information

High Static, Low Static, and Built In Ducted indoor units include factory-installed drain pumps. When the bottom surface of the indoor unit is at an elevation below the receiving building drain line connection, install an inverted trap at the top of the condensate pump discharge riser before connection to the building drain pipe.

When the receiving drain line is mounted horizontal, connect the inverted trap to the top half of the pipe. The connection point of the inverted trap to the building drain pipe should always be to the top half of the pipe and should never be over 45° either side of the upper most point of the horizontal building drain line.

If connecting to a vertical drain line or plumbing system vent line,

General Drain Piping Information

Drain Piping

• Drain piping must have down slope (1/50 to 1/100).

• Any holes through the ceilings, walls, etc., must be large enough to accommodate the drain piping and insulation.

• To prevent reversal flow, do not provide up and down slope.

• For High Static, Low Static, and Built In Ducted Units, the outside diameter of the drain connection on the indoor unit is 1-1/4 inches.

• For Vertical / Horizontal Air Handling Units, use PVC with a 3/4” male pipe thread fitting for the condensate pan.

• For High Static, Low Static, and Built In Ducted Units, the drain piping material is polyvinyl chloride pipe (1 inch).

Drain Leak Test

A leak test should be performed 24 hours after the drainage system has been installed.

Drain Pipe Insulation

To prevent condensate from forming on the drain piping, field- supplied 5/16 inch thick polyethylene insulation should be properly installed.

Common Indoor Unit Drainage System

It is usual work practice to connect individual indoor unit drain pipes to one common indoor unit drainage system.

45° to 60° Angle

The diameter of the common vertical drain pipe should be as large as necessary. The diameter of the horizontal pipe should be the same or larger than the vertical drain pipe. To avoid property damage in the event of the primary drain becoming clogged, and to optimize drain system performance, it may be prudent to install a secondary drain line.

Design the drain system to plan for winter operation (condensate line may freeze up if condensate does not properly drain away). Drain all generated condensate from the external condensate pan to an appropriate area. Install a trap in the condensate lines as near to the indoor unit coil as possible. To prevent overflow, the outlet of each trap should be positioned below its connection to the condensate pan. All traps should be primed, insulated, and leak tested.

General Power Wiring / Communications Cable Guidelines

• Follow manufacturer’s circuit diagrams displayed on the inside of the control box cover.

• Have a separate power supply for the indoor units.

• Provide a circuit breaker switch between the power source and the indoor unit.

• Confirm power source specifications.

• Confirm that the electrical capacity is sufficient.

• Starting current must be maintained ±10 percent of the rated current marked on the name plate.

• Confirm wiring / cable thickness specifications:

• Power wiring is field supplied. Wire size is selected based on the larger MCA value, and must comply with the applicable local and national codes.

• Communication cable must be a minimum of 18 AWG, two-conductor, stranded, shielded, and must comply with the applicable local and national codes. Ensure the communication cable is properly grounded at the master outdoor unit only. Do not ground the ODU-IDU communication cable at any other point.

• It is recommended that a circuit breaker is installed, especially if conditions could become wet or moist.

• Include a disconnect in the power wiring system. Add an air gap contact separation of at least 1/8 inch in each active (phase) conductor.

• Any openings where the field wiring enters the cabinet must be completely sealed.

Wired Controller Placement

Wired controllers include a sensor to detect room temperature. To maintain comfort levels in the conditioned space, the wired controller must be installed in a location away from direct sunlight, high humidity, and where it could be directly exposed to cold air. Controller must be installed four (4) to five (5) feet above the floor where its

LED display can be read easily, in an area with good air circulation, and where it can detect an average room temperature.
