Hot Gas Bypass Valve - hvacknowitall

The Hot Gas Bypass Valve Explained By Gary McCreadie. Hot gas bypass valves are a simple and very effective way to add a false load on an evaporator coil. What is a false load you ask. Well, as we have learned in the past, refrigerant pressures are directly related to the ambient temperature surrounding them.

INSTALLATION INSTRUCTIONS HOT GAS BYPASS …

The hot gas bypass valve (also called Discharge Bypass Valve, or DBV) responds to changes in downstream pressure (suction pressure ) from the evaporator. When the evaporating pressure is above the valve setting the valve remains closed. As the suction pressure drops below the valve setting, the valve responds and begins to open.

Operational Description - Rawal

This triggers instant response in the APR Control hot gas bypass valve and causes it to bypass some of the compressor discharge through the APR Control desuperheating chamber to the compressor suction return. This results in a decrease in hot gas to the condenser coil and ultimately less liquid refrigerant to the evaporator coil.
