ZX Platform Condensing Unit was designed based on three factors demanded by industry users:
Energy Efficiency
- Utilizing Copeland Scroll ® compressor technology, variable speed fan motor, large capacity condenser coil and advanced control algorithms, energy consumption is significantly reduced. End-users can save more than 20% on annual energy costs rather than using hermetic reciprocating units.
Reliability
- Combining the proven reliability of Copeland Scroll
®
compressors with advanced electronics controller and diagnostics, equipment reliability is greatly enhanced. Fault code alerts and fault code retrieval capabilities provide information to help improve speed and accuracy of system diagnostics. Integrated electronics provide protection against over-current, over-heating, incorrect phase rotation, compressor cycling, high pressure resets, low pressure cut-outs. It can also send out a warning message to an operator when there is a liquid floodback, which can prevent critical damage on the unit.
Flexibility
- The slim shape and light weight make the ZX Condensing Unit aesthetically appealing and easy to install. The ultra quiet variable-speed fan motor significantly reduces exterior sound levels, allowing additional location flexibility. Combined with wall mounting capability, the ZX Condensing Unit delivers unmatched flexibility.
ZX Condensing Units are greatly suitable for walk-in cooler and freezer applications.
The advance scroll compressor technology, fan speed control and electronic controller are precisely collaborated in all units.
It also introduces variable-speed fan motors that go beyond national standards. Guaranteed dependable performance and operation in food service applications while conveying higher energy efficiency and lower sound levels are the main objectives.
ZX – Design Platform
The ZX platform CDUs are designed to provide the best operational cost savings on a year around basis. Refrigeration equipment operate continuously for7 days, 24 hours and 365 days. The ZX and
ZXI compressors, injection scheme and heat exchanger designs are optimized to provide best efficiencies at annual averaged temperature rather than at typical rating conditions. The typical ambient on an annual basis follows a normal distribution pattern.
The highest and lowest ambient happens only for few hours as shown in figure 01.

ZX – Reliability Platform
Emerson Climate Technologies has designed the ZX platform
CDUs with extended operational capability in tough climatic conditions. With our vast experience in the refrigeration industry,
ZX platform CDU is designed with a good protection scheme. ZX protection scheme detect conditions that could cause damage to the compressor, initiates a warning, temporary shutdown and

ZX – Performance Platform
Emerson Climate technologies with its leadership in scroll compression technology, apply the most advanced techniques to maximize the possible operational efficiency at specific application envelopes. ZX MT CDU applies a patented suction-line injection technology.
Scroll compressor inherently operates at higher efficiency at MT application conditions. The suction-line injection provides a more reliable MT operating envelope.
ZX MT CDU applies ZX series scroll compressor with liquid injection into the suction-line using an electronic expansion valve (EXV).
The EXV maintains an optimum feed of partially vaporized liquid refrigerant in the compressor suction to maintain a safe discharge gas temperature. The controlled discharge gas temperature provides a more reliable solution for the MT envelope.
ZXL LT CDU applies vapor injection technology to achieve higher efficiency in LT refrigeration. Vapor injection allows an economizer cycle to be applied on a scroll compressor thereby greatly enhancing compressor efficiency. This technology can be likened to 2- stage compression with economizer cycle. Vapor injection improves efficiency by as much as 12% over a liquid injection system of the same type. ZXL LT CDU applies ZXI series vapor injected compressor with vapor injection plate heat exchanger (PHE) to implement the vapor injection technology.

ZX Platform – Scroll Superiority
Scroll compressors deliver flatter capacity compared to reciprocating compressor condensing units due to the high volumetric efficiency of scroll compressors. Flatter capacity can otherwise be described as lower change in capacity with change in outdoor ambient. This is schematically shown in Figure 03. Flatter capacity brings certain inherent advantages, which highly benefit users and stored products.
Some of the benefits of flatter capacity on ZX platform CDUs are described below.
1.
Smaller unit selection:
Condensing units are selected to match the required refrigeration capacity at the highest required ambient. Flatter capacity allows a smaller unit selection compared to reciprocating compressor CDU.
2.
Lower operating cost:
At lower ambient conditions, ZX platform CDU delivers capacity closer to the cooling load. In contrast, reciprocating compressor CDU delivers capacity in far excess of what is required. This helps the ZX platform CDU to operate at relatively higher evaporating temperature. Higher evaporating temperatures improve compressor efficiency. In addition, higher evaporating temperature reduces the rate of ice formation on the evaporator coils/frost build-up. Lower frost build-up improves the evaporator heat exchange efficiency. It also reduces the defrost heat demand, thereby resulting in lower energy needed for defrost.
3.
Freshness of food:
Another benefit of higher evaporating temperature is reduced dehumidification by the evaporator coil.
This allows higher relative humidity in cold room or cold cases. Higher relative humidity reduces weight shrinkage and improves freshness of stored product.

Application Guideline
In ZX MT units, suction line injection is applied to the compressor suction. Suction line injection allows a reliable and efficient MT envelope of up to -15°C (R22) and -20°C (R404A) evaporating temperature. In suction line injection, a part of liquid refrigerant is added into the compressor suction gas. Suction injection de-superheats the suction gas and controls the compressor discharge temperature. This is implemented through electronic control by the E2 controller and an electronic expansion valve (EXV). The E2 monitors the compressor discharge temperature and optimizes the opening of the EXV for optimal discharge gas control.
In ZXL LT units, vapor injection is applied to the compressor. Vapor injection enhances the compressor efficiency by applying 2-stage compression with an economizer refrigeration cycle. Vapor injection eliminates the need for liquid injection, which would otherwise have been required to operate a reliable LT envelope down to -40°C evaporating temperature. In vapor injection, a part of liquid refrigerant is expanded and passed through a heat exchanger. In the heat exchanger, this expanded refrigerant absorbs heat from the main liquid line and sub-cool the main liquid. The expanded refrigerant vaporizes while passing through the heat exchanger and is supplied back into the scroll intermediate pockets through the vapor-injection tube. The sub-cooling of the main liquid increases the compressor capacity by as much as 30%. The figure 14 below identifies the key components of the vapor injection assembly.

ZX Platform Condensing Unit
Installation
Copeland ZX condensing units are delivered with a holding charge of neutral gas. The condensing unit should be located in such a place to prevent any dirt, plastic bag, leaves or papers from covering the condenser and its fins. The unit must be installed without restricting the airflow. A clogged condenser will increase the condensing temperature, thus reduce the cooling capacity, and lead to a highpressure switch tripping. Clean the condenser fins on a regular basis.
Installation / Piping Instructions
It is recommended that a clearance of 8 inches from the wall (or the next unit) be maintained from the unit’s left and rear panel whereas a clearance of 20 inches is to be maintained from the unit’s right, top and front panels. Both service access and airfl ow have been considered in making these recommendations. Where multiple units are to be installed in the same location, careful consideration for proper clearance needs to be given to each individual unit.
Ideally, the unit should be mounted level on a solid concrete slab with rubber strips between unit feet and concrete. However, these units have been designed for mounting on suitable brackets for wall mounting. In this case it is equally important that the spatial guidelines given above are followed, and additional consideration needs to be given for possible air recycling if units are stacked above and below each other. In general terms, air by-pass around each condenser and between each unit should be avoided at all times.
Pipe sizing should not only be of sufficient size to ensure optimum performance and good oil return, but it also needs to take into account the full capacity range through which this particular unit will need to operate. Follow the ASHRAE guidelines for proper piping practices.
Location and Fixing
The unit should always be installed in a location that ensures clean air flow. It is recommended that a clearance of 300 mm from the wall
(or the next unit) be maintained from the unit’s left and rear panels whereas a clearance of 500 mm must be maintained from the unit’s right, top and front panels (seen facing the front of the unit). Both service access and airflow have been considered in making these recommendations. Where multiple units are to be installed in the same location, the contractor needs to consider each individual case carefully. There can be many variations of unit quantities and available space and it is not the intention of this manual to go over these.
Ideally, the unit should be mounted on a solid concrete slab with anti-vibration pads between unit feet and concrete. However the ZX condensing unit has also been designed for wall mounting on suitable brackets. Wall mounting brackets are not included. Another factor to consider in finding a good installation site is the direction of the prevailing wind. For example, if the air leaving the condenser faces the prevailing wind, the air flow through the condenser can be impeded, causing high condensing temperatures ultimately resulting in reducing unit life. A baffle is a remedy for this situation.

Electrical Connection
Power Supply
The ZX condensing unit electrical connection to the power supply must be made by qualified technicians, who should refer to the electrical diagrams located inside the electric connection panel. The units are designed for below power supply at ± 10% voltage tolerance. The circuit breaker must be switched off before opening the front panel.

Refrigeration Connections
Refrigeration Piping Installation
All interconnecting pipes should be of refrigeration grade, clean, dehydrated and must remain capped at both ends until installation.
Even during installation, if the system is left for any reasonable period of time (say two hours), pipes should be re-capped to prevent moisture and contaminants from entering the system.
Do not assume that the service connection sizes on the unit (at the service valves) are the correct size to run your interconnecting refrigeration pipes. The service valve sizes have been selected for convenience of installation and in some cases (larger units) these may be considered too small. However for the very short pipe run within our units, these service connection sizes are adequate. All interconnecting pipes should be sized to satisfy the duty required.
Usually the suction line is insulated, but the liquid line is not. However the liquid line can pick up additional heat from the ambient and adversely affect the sub-cooling desirable for the liquid refrigerant before it enters the expansion valve.
The pipe should be sized to ensure optimum performance and good oil return. The sizing must also take into account the full capacity range through which this particular unit will need to operate.
Tube Size
Max distance between
2 clamp support
Pipe runs should be kept as short as possible, using the minimum number of directional changes. Use large radius bends and avoid trapping of oil and refrigerant. This is particularly important for the suction line. The suction line should ideally slope gently towards the unit. Recommendation slope is
1/200~1/250. P traps, double risers and reduced pipe diameters may be required for suction lines where long vertical risers cannot be avoided. All pipes should be adequately supported to prevent sagging which can create oil traps. The recommended pipe clamp support distance is shown in the table.

ZXL Liquid Line Insulation
ZXL liquid line should be insulated with a 19 mm insulation thickness. Temperature could be as low as –15°C.
Vapor Injection: Specific Application Tips
ZXL-LT CDU
ZXL-LT CDU applies vapor injection technology. As explained in the previous section, vapor injection improves LT operational efficiency and provides a reliable LT envelope. Vapor injection sub cools the main liquid line using the economizer cycle. The sub cooling of liquid line calls for some specific application tips which are applicable only for ZXL-LT CDU. They are;
1. Liquid line pipe connecting the CDU service valve to the evaporator expansion valve has to be well insulated separately. The recommended insulation thickness is 12.5 mm (1/2 inches)
2. The lower liquid in temperature can increase the evaporator expansion valve capacities. Please follow valve manufactures recommended liquid temperature correction factors for proper selection of evaporator expansion valve.

Brazing Recommendations
Maintain a flow of oxygen-free nitrogen through the system at a very low pressure during brazing. Nitrogen displaces the air and prevents the formation of copper oxides in the system. If copper oxidization is allowed to form, the copper oxide material can later be swept through the system and block screens such as those protecting capillary tubes, thermal expansion valves, and accumulator oil return holes.
This minimizes any entry of contaminants and moisture.
• Remove the liquid line connection cap.
• Then remove the suction connection cap.
• Open both valves midway. Care should be taken to avoid the holding charge from releasing too quickly.
• Be sure that tube fitting inner diameter and tube outer diameter are clean prior to assembly.
• Since both tubes are extended from the condensing unit housing, we recommend insulating the housing by using a wet cloth on the copper tubing.
• Recommended brazing materials: a copper / phosphorous or copper
/ phosphorous / silver alloy rod should be used for joining copper to copper whereas to join dissimilar or ferric metals, use a silver alloy rod, either flux coated or with a separate coating.
• Use a double tip torch.

Start Up and Operation
Before commissioning, ensure that all valves on the condensing unit are fully opened.
Evacuation
The evacuation procedure is based upon achieving an actual system vacuum standard and is not time dependent. Before the installation is put into commission, it has to be evacuated with a vacuum pump. Proper evacuation reduces residual moisture to
50ppm. The installation of adequately sized access valves at the furthest point from the compressor in the suction and liquid lines is advisable. To achieve undisturbed operation, the compressor valves are closed and the system is evacuated down to 0.3 mbar /
0.225 Torr. Pressure must be measured using a vacuum pressure (Torr) gauge on the access valves and not on the vacuum pump; this serves to avoid incorrect measurements resulting from the pressure gradient along the connecting lines to the pump.
Charging Procedure
Refrigerant Charging Procedure
The scroll compressor design requires system charging as quickly as possible with liquid refrigerant into the liquid line. This will avoid running the compressor under conditions where there is insufficient suction gas. Sufficient suction gas is available to cool not only the motor but also the scrolls. Temperature builds up very quickly in the scrolls if this is not done. Do not charge vapor (gas) refrigerant into the ZX Scroll unit. The suction service valve must not be fully closed at any time while the compressor is running. To do so would cause damage to the compressor in the same manner as explained above. This valve is provided for ease of connection and for the fitting of service gauges without removing the unit panel. It is recommended to charge the ZX unit with refrigerant via its service valves. It is recommended to break the vacuum in the system with a partial charge of the refrigerant, before starting the system. For charge adjustment, it is recommended to check the liquid sight glass just before the expansion valve.
Oil Charging Procedure
ZX CDUs are delivered with a full oil charge in both the compressor and the oil separator. The oil level should be visible in the compressor sight glass. All systems will trap some oil and in some cases it may be necessary to add oil if pipes are long, if the vertical rise is high and if the piping is not well designed. The oil level should be monitored carefully during commissioning, checked after 4 – 8 hours and checked again after 24 hours of normal operation. The ideal oil level is between ¼ and ¾ sight glass level but if any oil is visible in the sight glass the compressor can operate safely. If oil is not visible in the sight glass proceed as follows:
1. Perform a manual defrost on all evaporators simultaneously.
2. Operate the compressor (at 100% load for ZXD) for 5 minutes after defrost is complete. The unit will automatically tend to operate (at 100% load for ZXD) after defrost as the evaporators recover their set-point temperatures.
3. Check that the oil level is at ¼ sight glass or higher but not over the top of the sight glass.
4. If oil is not visible add oil until the level reaches the ¾ sight glass level.
10
Adding Oil
The simple and ideal way to add oil is to pump the oil into the suction side when the unit is running. Discharge pressure from the unit or refrigerant pressure from a cylinder can be used to force oil into the suction side. The oil will go directly into the compressor and the level increase will be immediate.
NEVER CLOSE THE UNIT SUCTION VALVE AND USE THE COMPRESSOR TO SUCK OIL FROM A CONTAINER THAT IS AT ATMOSPHERIC
PRESSURE. THIS COULD DESTROY THE SCROLL COMPRESSOR IN A MATTER OF SECONDS.
Tools required: Manifold gauge set and hoses, oil tank of ~ 1 litre volume with suitable connections, oil, refrigerant.

Scroll Compressor Rotation Direction
Rotation Direction of Three Phase Scroll Compressors will only compress in one rotational direction. Direction of rotation is not an issue with single phase compressors since they will always start and run in the proper direction. Three phase compressors will rotate in either direction depending upon phasing of the power. Since there is a 50-50 chance of connecting power in such a way as to cause rotation in the reverse direction, it is important to include notices and instructions in appropriate locations on the equipment to ensure proper rotation direction when the system is installed and operated. Verification of proper rotation direction is made by observing that suction pressure drops and discharge pressure rises when the compressor is energized. Reverse rotation of a scroll compressor also results in substantially reduced current draw compared to specification sheet values. Suction temperature will be high, discharge temperature will be low and the compressor may be abnormally noisy. There is no negative impact on durability caused by operating three phase Copeland Scroll compressors in the reversed direction for a short period of time (under one hour). After several minutes of operation in reverse, the compressor’s motor protection system will trip the compressor off. If allowed to repeatedly restart and run in reverse without correcting the situation, the compressor will be permanently damaged. All three phase scroll compressors are identically wired internally. As a result, once the correct phasing is determined for a specific system or installation, connecting properly phased power leads to the same terminals will maintain proper rotation direction.
Brief Power Interruptions
Brief power interruptions (less than ½ second) may result in powered reverse rotation of single-phase refrigeration scroll compressors.
High-pressure discharge gas expands backward through the scrolls at power interruption causing the scroll to orbit in the reverse direction. If power is reapplied while this reversal is occurring, the compressor may continue to run noisily in the reverse direction for several minutes until the compressor internal protector trips. This has no negative effect on durability. When the protector resets, the compressor will start and run normally.
Maximum Compressor Cycle
Maximum permitted starts per hour is 10.
Check Before Starting & During Operation
Both valves should be fully opened on the liquid line, in order to prevent trapping liquid.
• Check that all valves are fully opened.
• After starting and operation conditions are stabilized, it is recommended to check oil level in the compressor(s) and see if there is a need to add oil to ensure a sufficient oil level (halfway up the sight glass).

ZX Platform Condensing Unit
Electronic Controller Assembly on a ZX Platform CDU
ZX/ZXL Controller Assembly
ZX platform E2 control offers multiple features which are unique to refrigeration condensing units. E2 real-time control monitors and optimizes the suction or vapor injection performance to offer efficient performance in ZX MT and LT units. E2 also monitors compressor operating parameters, so as to protect the system from unsafe operating parameters such as passing through a peak temperature hour of a peak ambient day; or drop-out of a power-phase; or continued refrigerant loss in the system. E2 controller detects these situations and, as a first step, will initiate some corrective actions.
For example, when the LT unit experiences an extreme temperature day, E2 control decides to switch from vapor-injection-optimization to discharge-gas temperature-control to allow the compressor to run safely and pass the extreme weather hours.
Another fault condition which is common in refrigeration systems is compressor overload. If the condenser coils are not cleaned regularly, the compressor operating discharge pressures rises. This condition is gradual and in conventional CDUs, no advance warning is provided to the user on this approaching undesirable situation. Ultimately, in such a situation, the internal protector in the compressor trips. Two problems arise due to internal protector-trip. First: there is no alarm to detect the trip and second: a compressor internal protector reset may take as long as an hour. This could be critical for the quality of frozen food in freezers or cases. On the other hand,
ZXL E2 controller detects the overload externally and actions a temporary shutdown. E2 Diagnostics will then start transmitting a fault signal. After multiple attempts, and if the error repeats itself as high as six times within an hour, the E2 will finally shutdown the unit to avoid expensive compressor failure.
The E2 will activate a buzzer to send an alarm signal at unit-lockout which then requires a manual restart. The buzzer is a standard part of the ZX platform Gold version CDU . The buzzer can be remotely mounted and has volume and mute capability. The E2 is also designed to activate an externally connected telephone dialer to send fault notice on a preset telephone number.
ZX platform units are designed to operate under extreme ambient temperatures of up to 48°C. This extremely high-ambient envelope, combined with the intelligent E2 controller, provides unparalleled benefits to customers.
The E2 control is also designed to apply a ZX defrost (DF) module. The ZX DF module is a basic time initiated DF module and is supplied as an optional accessory. The DF module has two rotary switches by which the user can set up the defrost duration and defrost interval. The DF module also enables a manual defrost as an override to the rotary switch setting of defrost interval.
The E2 controller consists of two electronic board assemblies: E2 power board and control board. The power board supplies constant DC power to the E2 control board.
The E2 control board carries the intelligent chip containing the canned programs. The entire assembly is pre-installed and wired in the factory on a new unit. Both electronic boards carry a LED light . If the LED lights are on after power-up of the unit, it indicates normal and proper operation of the electronic boards. Once these lights are on, the rest of the unit including the compressor is monitored and digital messages are shown on the diagnostic panel.
Table 01 shows a list of fault detections enabled by E2 controller and diagnostics on ZX platform CDU. The diagnostics are standard features on the Emerson ZX platform Gold version.
Table 02 summarizes fault conditions under which the E2 controller initiates “temporaryshutdown—with-auto-restart” and “lock-out trip-condition with- manual-restart.”

E2 Control Board Dip
Switch Setting
T he E2 control board has two dip switches (2-bit and 3-bit) and one rotary switch. The rotary switch and the 2-bit dip switch are used in combination to select the compressor used on the unit. The selected compressor relates to the over-currentlimit for the specified unit. The 3-bit dip switch is used if the customer chooses to use the E2 control for evaporator fan control. Fig 15 shows the dip switches and rotary switch in the E2 control board.

The controller has been pre-programmed with a number of parameter values that are most likely correct. Individual installation requirements, however, may make it necessary to alter parameter settings.
The control target of the compressor controller is to maintain the suction pressure (or saturated suction temperature) at a defined value by varying the available compressor capacity.
The control target of the fan speed controller is to maintain the average condenser mid coil temperature and hence the average discharge pressure at a defined value. This is achieved by varying the fan speed. The setpoint can be altered using the SEtF parameter.
