Check 27+ pages function of back pressure valve in refrigeration system analysis in PDF format. 18Until the pressure in the evaporator exceeds the spring pressure the valve remains open. The rate of flow of liquid refrigerant into the evaporator. The vegetable room is maintained at a temperature of 4 C to-6 C while the fish room and the meat room are kept at a temperature of-12 C to-14 C. Read also back and function of back pressure valve in refrigeration system Therefore even though the valves are selected on the basis of the pressure drop at full load conditions they should.
This function requires the system to have additional refrigerant available that it wont need during summertime operation when head pressure will be above the valves control setting. Operating refrigerant pressures may be observed on theservice gauge manifold when hoses are connected to theseports and the valves.
Back Pressure Valves Back Pressure Valve In Refrigeration System It is a non return valve fitted at the outlet of evaporator to facilitate slow cooling in an evaporator chamberlike veg room in ship.

Back pressure valves and regulators are also similar to pressure relief valves in that both control their inlet pressure.
6The hot gas bypass utilizes a line from the discharge of the compressor to deliver high temperature high pressure refrigerant either to the evaporator distributor preferred or the suction line to the compressor which may overheat the compressor. NRD is fully open at delta-p 435 psi 30 bar. There are two main reason to fit the back pressure valves. Back pressure valves are fitted at the outlet of refrigerating chamber having multiple refrigerating room with different temperature. A servicevalve called the king valve is mounted on the outlet of the re-ceiver. This expansion pushes the needle back into the valve seat and stops the flow of refrigerant.
