Hello eveyone,

I'm on a new project in which customer wanted a Hotgas bypass for not stopping compressor when thermostat is ON. I won't use bypass for defrost but just to keep compressor running even if the room is in desired temperature.

What would happen if i add a bypass line to Evaporator inlet and let the thermostat control the solenoid valve? In my plan when the thermostat reaches to desired temperature then solenoid will open. Do i need an additional HGBV? As i told i don't need bypass gas for defrost as my conditions are not so low.

System is with below conditions;
Its an air conditioning system
System will work between 56 F to 122 F
Compressor semi hermetic
Capacity 4.5 kW maximum
Valve block expansion valve 1.5 tons
Gas R134a 1.8 kg.

Thank you very much for your time
