Abstract

The invention relates to refrigeration application, and relates to an ammonia separation plate type heat exchanger ice water control unit. The unit comprises a gas-liquid separator, a plate type heatexchanger, an air suction pipeline, an exhaust pipeline, a defrosting pipeline and a liquid inlet pipe; the air suction pipeline comprises an air suction pipe, an electromagnetic main valve, an electromagnetic adjusting pilot valve and a first controller; the defrosting pipeline comprises a defrosting pipe, a second controller and a defrosting electromagnetic valve; the defrosting electromagneticvalve is arranged on the defrosting pipe, and the second controller is connected with the defrosting electromagnetic valve; and a liquid level control assembly comprises a liquid level controller, a liquid level sensor, a floating ball liquid level switch and an alarm. The unit has the beneficial effects that the air suction pipeline is arranged so that adjustment can be performed according to thewater outlet temperature of the plate type heat exchanger; the defrosting pipeline is arranged so that the ice on the ammonia separation plate type heat exchanger can be melted; the floating ball liquid level switch is additionally arranged so that when the liquid level in the gas-liquid separator reaches the upper limit, interlocking shut down can be carried out on the ammonia separation plate type heat exchanger ice water control unit.

Description

technical field [0001] The invention relates to refrigeration applications, and relates to an ammonia separating plate for ice water control unit. Background technique [0002] In the existing AFBZ ammonia separation plate ice water control unit, the liquid supply of the unit is controlled by the liquid level controller to control the opening of the liquid supply solenoid valve, to maintain the normal liquid level of the ammonia liquid separator, and to connect with the user's control center to carry out Remote PLC control. [0003] The high-pressure ammonia liquid turns into a low-temperature and low-pressure liquid through the throttle valve and enters the gas-liquid separator, enters the plate heat exchanger (evaporator) by gravity, absorbs the heat of the refrigerant, evaporates into gas and enters the gas-liquid separator, and the separated gas passes through The main valve is returned to the suction port of the compressor, and the heat of the refrigerant is taken away...
