Danfoss 068U3749 Hot Gas Bypass Valve TUH

The Danfoss 068U3749 Hot Gas Bypass Valve is used for HVAC systems that are aimed at controlling the compressor under various loads. As for the operation of this valve, it works in such a way that, during low loads, and to prevent the evaporator from freezing, some of the hot refrigerant gas from the discharge line from the compressor is allowed to be returned into the evaporator. It adapts to suction pressure changes and prevents the compressor from being overloaded even when there is a low cooling requirement. This capability is particularly useful in air conditioning and refrigeration where tight temperature control is always essential.
