| Message: | Introductionevaporator pressure regulators are widely used in the suction line of evaporator. They are used to protect against too low an evaporating pressure by throttling down when the pressure falls below the set value. 1.Maintain a constant evaporating pressure and thereby a constant surface temperature on the evaporator. Theregulation is modulating. By throttling in the suction line,the amount of refrigerant gas is matched to the evaporator load. 2.Protect against an evaporating pressure that is too low. The regulator closes when the pressure in the evaporator falls below the set value. 3.They are also used in differentiate between the evaporating pressures in two or more evaporators in systems withone compressor. url:http://www.fs-controls.com |
