How A Heat Pump Reversing Valve Works Youtube In this video we take a look at how a reversing valve works in a heat pump, we explain the basic operation of a split system air source heat pump as well as. In this hvac training video, i show how the reversing valve works on a heat pump for heating and air conditioning. i show each component on the inside as wel.
How The Reversing Valve Works In A Heat Pump Hvac Training Youtubeо A quick overview of how a reversing valve on a heat pump system works. a heat pump system is really just an air conditioning system that uses a reversing val. The y signal energizes the contactor to power the compressor and outdoor fan motor. a y signal without an o signal runs the unit in heating mode. a y signal with an o signal energizes the reversing valve to initiate the cooling cycle. the w signal energizes the backup heat ( often electric strip heat).hope that helps. Its temperature and pressure rise in the compressor, and it moves to the condenser coils to reject its heat outside. a heat pump reversing valve simply reverses the process by cycling the refrigerant the opposite way. it makes the condenser function as the evaporator and vice versa. you can see the heating cycle in the image below. The operation of the reversing valve is fundamental in changing a heat pump’s mode: mode switching: the valve directs the refrigerant flow, determining whether the heat pump heats or cools. control mechanism: the solenoid controls the valve, which the heat pump’s thermostat activates. shift in flow: depending on the signal from the.
