Air is drawn into the system through the return duct from the space by the fan. The air is pushed across the
condenser (heating) coil where the air is heated and returned to the space through the supply ducts.
The evaporator coil is treated by a second set of ductwork that will bring in outside air and push it across the
evaporator (cooling) coil where the refrigerant absorbs heat from the air. The colder air is then discharged out of
the unit.
Refrigerant/Coolant Cycle:
Cooling Cycle Diagram A:
The refrigerant in this cycle will move in a counterclockwise pattern, following the blue arrows in Diagram A for
refrigerant flow in cooling mode. Beginning just after the expansion valve (D) the refrigerant starts off as a low
temperature, low pressure liquid. Under this low pressure condition the refrigerant has a low boiling point. The
refrigerant is pushed through the evaporator coil (F) where it absorbs heat from the warm air that is passing over
the coils. The heat absorbed by the warm air causes the refrigerant to boil and become a vapor. The refrigerant
continues through the system toward the compressor (C), note the position of the reversing valve. As it enters
the compressor the refrigerant is a low temperature, low pressure vapor.
The refrigerant enters the compressor where it is pressurized into a high temperature, high pressure vapor. The
refrigerant is now under very high pressure and has a high boiling point. At these conditions, the refrigerant can
condense easily. As the refrigerant moves through the condenser coil (A) the fan (B) inside the unit is pushing air
across the coils. The refrigerant will expel heat to the passing air as it is pushed though the fins by the fan. The
passing air will absorb the heat, causing the refrigerant to cool and condense into a liquid. The high-pressure
liquid moves towards the outlet of the condenser, the expansion valve. The refrigerant will enter the valve as
a high temperature, high pressure liquid. The valve will allow the pressure of the refrigerant to change and the
refrigerant will exit the valve as a low temperature, low pressure liquid and start the process over again.
Heating Cycle Diagram B:
The refrigerant in this cycle will move in a clockwise pattern, following the blue arrows in Diagram B for
refrigerant flow in heating mode. Beginning just after the expansion valve (D) the refrigerant starts off as a low
temperature, low pressure liquid. Under this low pressure condition the refrigerant has a low boiling point. The

valve. The refrigerant will pass through the valve as a high temperature, high pressure liquid and it will come out
as a low temperature, low pressure liquid and start the process over again.
System Variations:
1. The setup and layout of a heat pump can vary depending on the design and manufacturer.
2. The discharge side of the unit may be located outside of the building while the supply side is located inside
the building.
3. Depending on design the discharge side of the heat pump may be treated by water or outside air.
4. The overall unit may be built as a complete all-in-one box unit or as two separate units connected by
refrigerant lines.
