Evaporator

(heat

exchanger)

Function of evaporator:

Make the low pressure refrigerant liquid

from capillary or expansion valve happen

heat exchange with air

Capillary

(throttle

components)

Function of capillary:

Utilize aperture and length change bring

pressure gap., control refrigerant flow

quantity and pressure

One way valve

One way valve is used for heat pump

unit, it make the refrigerant

liquid only flow as the arrow direction

Four way valve

Function of 4 way valve:

When change cooling mode into heating

mode, it will change the flow direction of

refrigerant;

When heating, the valve get electricity

(cooling without electricity), the slip

assembly move to the right connect pipe 2

and 3, so change the flow direction.
