Description
The Lennox 37729 Refrigerant Check Valve, which is a small but essential element of HVAC equipment such as air conditioning and heat pumps. This directional control is essentialfor two reasons. First, it means that there is a heat transfer. Refrigerant takes heat from the warm air inside the building and releases it into the environment. The check valve has the role of making sure that the refrigerant does this cycle by discouraging its backward flow. Second, it protects the compressor and other parts of the HVAC system.
