Application: application: danfoss EKC312 electronic expansion valve controller used for accurate control of refrigeration system superheat: factory (chiller), cold storage (cold) fan, air conditioning unit. Advantage: the optimization to the evaporator for fluid volume, save energy, the actual heat always be optimized to the minimum allowable under the condition of heat. Function: the degree of superheat control (adaptive heat or load defined degree of superheat), MOP function, on/off signal input to realize the start/stop control, PID regulation. System: degree of superheat of evaporator can be achieved by a pressure sensor and a temperature probe S2 P. System USES the expansion valve with the stepping motor ETS. When the controller accident after power off, often in the safety considerations, to the evaporator for fluid must be cut off. At this point, however, due to ETS electronic expansion valve is driven by stepping motor, it will stay open. Equipped with a UPS power supply in the case of accidental power, to power a controller to make the valve closed or ETS before ETS add a solenoid valve can solve this problem.
