Refrigerant Solenoid Stop Valves

Posted on by combine refrigration & air conditioning services

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.

Thermal Expansion Valves

Posted on by combine refrigration & air conditioning services

The thermal expansion valves control the quantity of liquid refrigerant that passes to each refrigerant circuit within the cooling coils. They are designed to maintain a constant °ee of superheat in the refrigerant gas leaving the cooling cools regardless...

Ship's Stores Refrigeration System

Posted on by combine refrigration & air conditioning services

The ship's stores refrigeration plant is served by two compressors located in the engine room. The ship's stores plant aft is the direct expansion type and uses Freon-12 as the refrigerant. Each of the compressor units has a capacity of 8.55 tons at -15°...

How Thermostatic Expansion Valves (TXV) Work

Posted on by combine refrigration & air conditioning services

Since the minimum efficiency regulation changed to 13 SEER in January 2006, most OEM systems now incorporate a thermostatic expansion valve (TXV) style metering device as the standard for air conditioning systems. It is now extremely important for the...

Compressor Operation - The Refrigeration Cycle

Posted on by combine refrigration & air conditioning services

Compressor Operation - The Refrigeration Cycle Refrigerant compressors work by taking in low pressure gas on the inlet and compressing it mechanically. Different types of compression mechanisms are what differentiate compressors (discussed below). This...

Compressor

Posted on by combine refrigration & air conditioning services

we will be going over the different types of air compressors. As we discussed last week, an air compressor takes ambient air and decreases its volume. This causes the pressure and temperature to rise. Decreasing the volume is the "compressing" that air...
