Heat Pump System Diagram

In addition to the evaporator and condenser the heat pump system also has a compressor and a metering device.

Heat pump system diagram.

A heat pump system has four major system components. In heat pump system there are at least 8 wires that need to be connected to the thermostat for proper operation. The heat pump works in conjunction with the air handler to distribute the warm or cool air to interior spaces. Thanks to a reversing valve a heat pump can change the flow of refrigerant and either heat or cool a home.

Heat is absorbed from this location and transferred outside usually behind or underneath the unit where the condenser coil is located. 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. Air is blown over an evaporator coil transferring heat energy from the air to the refrigerant. A refrigerator is essentially an insulated box with a heat pump system connected to it.

It takes less energy to relocate heat than it does to create it. A typical air source heat pump system is a split or two part system that uses electricity as its power source. The evaporator coil is located inside the box usually in the freezer compartment. 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.

The system contains an outdoor unit that looks similar to an air conditioner and an indoor air handler.
