What happens if a reversing valve fails in a heat pump?
Reversing valves are built into the heat pump by the manufacturer, and must be replaced by an HVAC technician if they fail. Since the valve is an integral part of the sealed refrigerant circuit, proper procedures for recovering and then later refilling the refrigerant must be followed, to prevent its loss into the atmosphere.
Do air-source heat pumps have reversing valves?
As you can see in the image above, a check valve on each metering device determines which expansion device to use and which one to bypass. Then there's the obvious answer: air-source heat pumps have reversing valves while basic A/C units do not. The reversing valve does its job by diverting the refrigerant flow in the suction and discharge lines.
What happens when the revering valve operates in cooling mode?
When the revering valve operates in cooling mode. The refrigerant will leave the compressor and head to the revering valve. It will be diverted out the lower left pipe and flow into the outdoor unit where it will give up some of it's thermal energy.
