Dual evap refrigeration

The plant supplies liquid refrigerant to the evaporators to maintain the refrigerated spaces listed below at the temperature indicated. These are only on the forward units. It may also pass through a liquid line dryer, an electrically operated solenoid, which senses cooler outlet temperature, and finally to the thermostatic expansion valve to the cooler.

A bypass valve is provided in the liquid line to the interchanger. Receiver Specifications Refrigerant capacity lbs.

The system is a closed loop. The cold suction gas cools the warm liquid refrigerant, thus, increasing the efficiency and capacity of the system. The shell is provided with one refrigerant inlet and two outlet connections and a magnetic float type indicator for determining the liquid level.

The chiller cools the glycol for use as a cooling medium in the forward reefer units. The higher temperature compartments are provided with ceiling suspended type cold diffusers which contain a direct expansion cooling coil constructed of copper finned tubing enclosed in a galvanized casing with a drip pan.

After the Freon has cooled the water, it passes through a back pressure regulator and continues back to the main system. Compartment Temperature Type of Evap. A dual pressurestat which automatically starts and stops the compressor during normal operation.

Thermal Expansion Valves The thermal expansion valves control the quantity of liquid refrigerant that passes to each refrigerant circuit within the cooling coils. The condenser water regulating valve should be set to maintain a condensing pressure of approximately psig. Finned coils sq. Thermal Expansion Valve TEV The solenoid stop valves, actuated by temperature control switches, cut off the supply of liquid refrigerant to the thermal expansion valves when the desired temperature is reached in the space or medium being cooled.


The pump is a single stage centrifugal pump that can produce 25 gpm. Suction gas circulates through the tubes of the heat exchanger while liquid refrigerant passes through the shell.

Thus, their dual function is; automatic expansion control and prevention of liquid refrigerant from surging back to the compressor. The capacity is reduced with reduction in suction pressure.

One compressor can handle the entire load with the other compressor remaining as standby or, if necessary, being using to operate the auxiliary water chiller. The cooler itself uses Freon R mainly to cool the walk-in on "B" deck. Cold diffuser 1 The plant also provides refrigeration for two service box brine coolers, two ice water coolers, and may be used to serve the auxiliary water chiller.

Each of the compressor units has a capacity of 8. These units supply R to two evaporator coils located on either side of the machinery space.

The refrigerant vapor is admitting to the shell and condenses on the outer surface of the finned tubes.GAH manufacturer of refrigeration for refrigerated vans and vehicles.

Dual evaporators are separate evaporators for the freezer and refrigerator section, increasing climate control and temperature management in both compartments, keeping food fresher.

Digital sensors constantly monitor conditions within the refrigerator, while the Linear Compressor and Dual Evaporator react to keep humidity at bay.
