The reversing valve is a regulator that changes the direction of the refrigerant inside the heat pump. It reverses the refrigerant flow to turn the refrigeration cycle from heating to cooling or the other way around. This aids a heat pump to deliver both heating and cooling capacity, with the same equipment and just a slight change on the inside.

HOW TO DIAGNOSE AND CORRECT REVERSING VALVE

holds the valve in this position until the solenoid is energized. To start the reversal of the cycle from cooling to heating, the solenoid is energized. Figure 2 shows what the system looks like after that happens. In the pilot valve, the plunger on the right has been pulled off

Air Source Heat Pumps Explained - Which?

Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. A heat pump is a mechanical system that allows for the transmission of heat from one location (the "source") at a lower temperature to another location (the "sink" or "heat sink") at a higher temperature.

Heat pump 4 way reversing valve & compressor failures

The way the reversing valve works is the solenoid valve opens pressure ports to operate a nylon slider in the cylinder. This cylinder can jam or bind half way and will over heat the compressor in a few minutes. Once this happens there is little chance that the valve will work again. If the valve is over heated
