APPLICATION EXAMPLE• Evaporating pressure regulating valve type EPR Fitted at the evaporator outlet to keep suitable set evaporating pressure. At multi evaporator system, evaporating pressure regulating valves are used to control each different pressure (temperature) of evaporators. Compressor operates based on the lowest pressure (temperature) of evaporators, pressure regulating valves keep pressure (temperature) of each evaporator at their setting pressure.
In this case, a check valve is required at the outlet of lowest pressure evaporator. Also, evaporating pressure regulating valve is used at water chiller for prevent form congelation of cool water and vegetable warehouse for prevents form over dehumidification.
