Heat Pump System Diagram

Heat pump thermostat wiring a typical wire color and terminal diagram as shown in the diagram you will need to power up the thermostat and the 24v ac power is connected to the r and c terminals.

Heat pump system diagram.

The heat pump works in conjunction with the air handler to distribute the warm or cool air to interior spaces. A heat pump is an air conditioning system which can also provide very efficient heating. Thanks to a reversing valve a heat pump can change the flow of refrigerant and either heat or cool a home. It takes less energy to relocate heat than it does to create it.

A refrigerator is essentially an insulated box with a heat pump system connected to it. A heat pump system has four major system components. In addition to the evaporator and condenser the heat pump system also has a compressor and a metering device. In heat pump system there are at least 8 wires that need to be connected to the thermostat for proper operation.

The evaporator coil is located inside the box usually in the freezer compartment. Air is blown over an evaporator coil transferring heat energy from the air to the refrigerant. 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.

Heat is absorbed from this location and transferred outside usually behind or underneath the unit where the condenser coil is located.
