Heat Pump System Diagram

Air is blown over an evaporator coil transferring heat energy from the air to the refrigerant.

In addition to the evaporator and condenser the heat pump system also has a compressor and a metering device. Thanks to a reversing valve a heat pump can change the flow of refrigerant and either heat or cool a home. A refrigerator is essentially an insulated box with a heat pump system connected to it.

A typical air source heat pump system is a split or two part system that uses electricity as its power source. A heat pump is an air conditioning system which can also provide very efficient heating. The heat pump works in conjunction with the air handler to distribute the warm or cool air to interior spaces. It takes less energy to relocate heat than it does to create it.

Heat is absorbed from this location and transferred outside usually behind or underneath the unit where the condenser coil is located. Just as a refrigeration system removes and relocates heat from a cooler or freezer so too does a heat pump remove heat from cold outdoor air and relocate it to within a building. These two system components maintain the flow of refrigerant through the heat pump system and also maintain the heat transfer coils at the desired temperatures and pressures. The system contains an outdoor unit that looks similar to an air conditioner and an indoor air handler.

The evaporator coil is located inside the box usually in the freezer compartment.
