The heat pump reversing valve is the only difference between the heat pump and standard air conditioner. Previously we have talked about how a heat pump works. We concluded it works just like an air conditioner, moving heat from one place to another.
A reversing valve a type of valve and is a component in a heat pump , that changes the direction of refrigerant flow. By reversing the flow of refrigerant, the heat pump refrigeration cycle is changed from cooling to heating or vice versa. The reversing valve is the component of a heat pump system that determines whether the system runs in heat or cool.
They are in fact, an assembly of two valves : the main valve which actually directs the refrigerant flow in the system, and a pilot valve which controls the main valve. We describe how a heat pump reversing valve works, how to find the reversing valve , and we include reversing valve troubleshooting advice and research articles. 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 a look at heat pump reversing valve.
The valve has two settings within it: one is excite the other is relaxed.
