Abstract

The invention discloses a blocking control system for cold storage air-cooler baffle doors. The blocking control system for the cold storage air-cooler baffle doors comprises a defrosting system. Thedefrosting system comprises a compressor, a refrigerant outlet of the compressor is connected with one end of a first solenoid valve and one end of a second solenoid valve separately; the other end ofthe first solenoid valve is connected with an liquid inlet of a liquid accumulator through a condenser; a liquid outlet of the liquid accumulator is connected with one end of a throttle valve; the other end of the throttle valve is connected with a refrigerant inlet of an air-cooler after confluence with the other end of the second solenoid valve; a refrigerant outlet of the air cooler is connected with a refrigerant inlet of the compressor through a gas-liquid separator; an air manometer is installed on the upper part of the interior of the air cooler; and an air outlet and an air inlet areformed in the upper side and the lower side of the air cooler, and the air-cooler baffle doors are separately arranged on the air outlet and the air inlet. The automatic opening and closing of the cold storage air-cooler baffle doors can be realized, the air-cooler baffle doors are automatically controlled, the defrosting heat diffusion can be significantly reduced, and the temperature in a storage can be kept stable.

Description

technical field [0001] The invention relates to the technical field of defrosting control of a refrigeration system, in particular to a barrier control system for a cold storage fan damper door. Background technique [0002] At present, in the low-temperature refrigeration system, it is necessary to frequently melt the frost layer or ice layer on the surface of the evaporator in the air cooler to improve the heat transfer capacity of the evaporator in the air cooler, thereby improving the working efficiency of the entire refrigeration system and reducing the Operating costs. [0003] In the cryogenic refrigeration system, when melting the frost layer or ice layer on the surface of the evaporator, it is necessary to prevent the defrosting heat from spreading into the cold storage body to reduce the working efficiency of the system. The defrosting space of the air cooler. [0004] Existing general air cooler damper door does not have automatic control system. Usually, at th...
