Compressor Application Manual

We will show below how a basic refrigeration

system works:

The compressor draws in the refrigerant fluid from

the evaporator by reducing the pressure in this

component. The fluid is compressed by the

compressor and moves to the condenser. In the

condenser the refrigerant fluid under high pressure

releases heat to the environment and becomes

liquid. The next component of the circuit is the

control device, which may be a capillary tube or an

expansion valve. The control element reduces the

pressure of the liquid refrigerant which was formed

in the condenser. This drop in pressure permits the

refrigerant to evaporate at low temperatures and

return to the gaseous state when passing through

the evaporator.

The change from a liquid to gaseous state requires

heat. So the refrigerant fluid removes the heat from

inside the refrigeration system through the

evaporator. The condenser releases this heat into

the environment. The control element offers a certain

resistance against the refrigerant's circulation,

separating the high pressure (condenser) from the

low pressure (evaporator) side.

The refrigeration system also uses a filter drier

with desiccant to retain any water that may be left

in the system.

The oil cooling tube that exists in some compressors

is used to help reduce the compressor temperature.

Lastly, there are systems that use a suction

accumulator to evaporate any residual liquid

refrigerant, stopping it from returning through the

suction line.
