The Basic Concepts of Refrigeration

BUCUN BENGKEL :  The refrigeration cycle uses the following parts/components :

1.  Compressor(high pressure type)

Receive (gas suction) from accumulator and compress it to make high pressure and high temperature gas for the condenser.

2. Condenser

Release heat from high pressure and high temperature refrigerant into the atmosphere, to liquid refrigerant.

3. Capillarity tube or expansion valve

Supply sufficient amount of liquid refrigerant to evaporator. Reduce pressure to vaporize liquid for evaporator.

4.  Liquid side piping

Liquid refrigerant flows from capillarity tube to evaporator through copper pipe.

5. Evaporator (Heat Excange)

Absorb heat from the room through vaporizing process of refrigerant.
6. Gas side piping

Refrigerant gas flows from evaporator to accumulator through copper pipe.

7. Accumulator

Separate refrigerant gas from liquid. (Accumulate liquid refrigerant to vaporize it from compression process).
