Remote Condenser

Introduction

General Information

Ice-O-Matic Remote Condenser Systems are comprised of three components. The pre-charged remote condenser, the pre-charged ice maker and the pre-charged line set. The pre-charged line sets are available in 25, 40, 45, 60 or 75 foot line set lengths. The 60 foot line set will require adding an additional 16 ounces of refrigerant to the system. The 75 foot line set will require adding an additional 28 ounces of refrigerant to the system.

Normal installation of the ice maker should be followed. Reference the installation instructions included with the ice maker.

In any installation, the pre-charged line sets, consisting of a liquid line (3/8” dia.) and a discharge line

(1/2” dia.) are used as a one time initial charge type installation.

Once the sealed couplings are connected and the internal seal is broken, the lines cannot be disconnected without losing the refrigerant charge. They are, however, reusable and when the couplers are removed and reconnected, the complete refrigeration system must be evacuated and re-charged with the proper amount of refrigerant. Reference the ice maker data plate or ice maker service manual for proper refrigerant charge.

General Description

The remote condenser should not be used in areas where sufficient airflow is not available in the area the ice maker is being installed or the heat being rejected by the condenser coil will be undesirable.

The condenser coil should not be exposed to temperatures below -20

°

F (-29

°

C) or above 120

°

F (49

°

C).

The remote condenser functions as a normal refrigeration system until the temperature at the condenser coil drops below 70

°

F. At this time the mixing valve will begin to bypass enough hot gas from the discharge line directly into the receiver to keep the liquid line feeding the expansion valve at a steady pressure. The amount of gas bypassed will depend on the temperature at the condenser coil (the colder the temperature at the condenser coil, the more gas will bypass and the tubing between the mixing valve and receiver will become warmer). For the complete explanation of this valve, refer to the schematic on page 6 of this manual.

VRC Condenser

Condenser Location

When choosing a location for the remote condenser, reference the following guidelines:

1. Choose a location that is protected from extremes of dirt, dust, rain, sun and prevailing winds.

2. Vertical air discharge mounting of the condenser is required.

3. Condenser should be mounted higher than the ice machine.

4. Condenser must be level.

5. Condenser should not be exposed to temperatures below -20

°

F or above 120

°

F.

6. Installation must meet all local and national building, plumbing and electrical codes.

Remote Condenser General Information

The

VRC

remote condensers incorporate the mixing valve in the condenser. This configuration allows up to a 100 foot calculated remote line set run. Reference the diagram below to calculate the maximum 100 foot line set run.

Limitations for new remote machines that have the mixing valve mounted in the condenser.

Maximum Rise is 35 feet.

Maximum Drop is 15 feet.

Maximum equivalent run is 100 feet.

Formula for figuring maximum equivalent run is as follows:

Rise x 1.7 + Drop x 6.6 + horizontal run = equivalent run.

Examples:

35 ft. rise x 1.7 + 40 ft. horizontal = 99.5 equivalent feet line run

35 ft. rise

40 ft. horizontal

Verify the ICE machine is compatible with the remote condenser. Some ice machines and some remote condensers may or may not have a Mixing Valve (Head Master). Only one valve is required per system. Kits are available to modify the remote condenser for compatibility. For more information contact your Ice-O-Matic Distributor.

10 ft. drop

10 ft. drop x 6.6 + 34 ft horizontal = 100 equivalent feet line run

Remote Condenser Remote Refrigeration System

The Remote Refrigeration System is shown in the above diagram. During the freezing cycle, high temperature and high pressure liquid refrigerant is directed from the condenser through a mixing valve, receiver, liquid line solenoid heat exchanger and a filter drier. The expansion valve meters refrigerant to the coils on the back of the evaporator.

In low ambient conditions (below 70

°

F air temperature at the condenser) the mixing valve opens to mix discharge gas with liquid returning from the condenser, in the receiver, to maintain discharge and liquid line pressures.

The low temperature and pressure refrigerant leaving the evaporator is directed through the suction line heat exchanger and is returned to the compressor. There it is compressed to a high temperature and high pressure gas. It is then directed to a condenser to be converted again to a high pressure and high pressure liquid.

During the harvest cycle, the hot gas solenoid valve (normally closed during the freeze cycle), opens and directs the high temperature gas leaving the compressor into the evaporator. Once the evaporator has reached approximately 40

°

F, the harvest motor overcomes the capillary attraction of the ice and the evaporator releases the ice. At the end of the harvest cycle, the hot gas solenoid valve closes and another freeze cycle begins.

During the off cycle, the liquid line solenoid valve closes and the system will pump down to 10-20 psi to prevent refrigerant migration to the low side of the system.

Remote Condenser

Mixing Valve (Headmaster, Low Ambient Control Valve)

Component Description

This valve serves as the head pressure regulating valve. It contains a pre-determined charge of nitrogen in the valve bellows. When the temperature at the condenser is above 70°F (21°C), the refrigerant flow from the compressor is directed by the mixing valve through the condenser and into the receiver. When the temperature at the condenser drops below 70°F (21°C), the pressure in the bellows of the mixing valve becomes greater than the pressure of the liquid refrigerant coming from the condenser.

This change allows the valve to partially restrict the flow of refrigerant leaving the condenser and allows discharge gas to by-pass the condenser and flow directly into the receiver, mixing with the liquid refrigerant from the condenser. The amount of discharge gas that bypasses the condenser increases as the ambient temperature decreases.

This action of the mixing valve allows the discharge pressure to be maintained at approximately 217 psi during low ambient conditions. If the refrigerant system is undercharged and the ambient temperature is below 70°F

(21°C), the mixing valve will not work properly. The mixing valve will allow too much refrigerant to bypass the condenser.

Receiver

The quantity of liquid refrigerant in the receiver will vary with the temperature at the condenser coil.

Liquid Line Solenoid and Pump Down Low Pressure Control

When the bin is full or the ON-OFF switch is turned to the OFF position, the liquid line solenoid valve closes and the system begins to pump down. When the low pressure reaches 10-20 psi, the pump down low pressure control opens and the contactor shuts the machine off.

As the ice is removed from the bin or the ON-OFF switch is turned to the ON position, the liquid line solenoid valve opens and the high side and low side pressures begin to equalize.

When the low side pressure reaches 50-75 psi, the pump down low pressure control closes and the machine begins a freeze cycle.

When the machine is off for extended periods of time (either a full bin or the ON-OFF switch in the OFF position), it will pump down approximately once every hour. This is due to the equalization of pressures during the off cycle resetting the pump down low pressure control. It is a normal function of the refrigeration system.

Condenser Fan Motor

The condenser fan motor is a single speed, permanent split capacitor motor and should be wired according to the wiring diagram. The motor is permanently lubricated for long service life.

Remote Condenser Installation

Proper Tubing Routing

When installing the discharge and liquid lines from the remote condenser to the icemaker, please use the following guidelines:

1. The remote condenser (#2) should always be installed above the icemaker (#4) as shown with a vertical air flow on page 8.

2. All excess tubing (#1) should be routed inside the building and coiled in a vertical spiral as shown

(3#) on page 8, to prevent oil trapping in the lines. Any tubing run outside should be insulated to protect it from surrounding ambient conditions. Tubing should follow straight line routing whenever possible. The lowest spot in the tubing run should be the connection at the rear of the icemaker.

Both the discharge line and liquid line quick connect couplers are supplied with a Schrader Valve on one end of the line set. The Schrader Valve end should be connected to the remote condenser on both the discharge and liquid line for access to pressure readings at the condenser as shown (#5) above.

When attaching the quick connect couplers (#6), always lubricate the couplers with refrigerant oil. The couplers should be tightened until snug, then tightened another quarter (1/4) of a turn.

Always leak check the quick connect couplers after installation has been made.
