Compressors
heat to the refrigerant Increases the temperature and pressure of the refrigerant Circulates the refrigerant through the system
Compressor
12,000 BTU's
one ton of refrigeration
where the heat is rejected
Condenser
It divides the high side of the system from the low side of a refrigeration system
metering device
Heat that can be sensed with a thermometer
sensible heat
A compressor in which the motor and the compressor are contained in the same pressurized housing
semi-hermetic or hermetic compressor
The most likely place you would find flash gas
Evaporator
Helps maintain a constant level of liquid refrigerant in a flooded evaporator
low side float
This is installed on vertical refrigerant piping risers to promote the flow of refrigerant oil
P-traps
The type of compressor that uses belts to turn the compressor
open type Compressor
Liquid refrigerant in the evaporator absorbs heat when it
boils
Thermostatic expansion valves are designed to maintain
superheat
The largest diameter line in a refrigeration system
suction line
It uses pistons to compress the refrigerant
Reciprocating compressor
Liquid refrigerant covers the tubes with a gas space on top
flooded evaporator
Refrigerant in the shell and water in the tubes
shell and tube type condenser
The most common type of metering device
capillary tube
Installed to remove small amounts of moisture
filter dryer
A compressor in which the motor and compressor are contained in the same pressurized housing and can be disassembled for field repair
semi-hermetic compressor
evaporator experiences a heat load increase, the suction pressure
increases
The single greatest cause of compressor failure
Dirty condensers
The purpose of an external equalizer line used with a thermostatic expansion valve is to compensate for
pressure drop across through evaporator coil
An accumulator is installed
before the compressor on the suction line
