Problems solved by technology

However, some industrial operations with high technological requirements need to use cooler air at a lower temperature to complete or achieve the desired effect
In addition, the general air cooler adopts the direct-exhaust suction and exhaust method to directly absorb the ambient air, and the cold air is directly discharged into the atmosphere after use. Dehumidifier, not ideal
Moreover, the direct row type consumes a lot of energy, resulting in energy waste

Embodiment Construction

[0013] Referring to FIG. 1 , the present invention is a circulating ultra-low temperature air cooler, which is mainly composed of a single-stage compression refrigeration system, a cascade refrigeration system, an air filter 20 and a fan 21 . The single-stage compression refrigeration system is mainly composed of a refrigeration compressor I1 , a first condenser 2 , a first dry filter 3 , a first liquid receiver 4 , a first throttle valve 5 and a first evaporator 6 . The refrigeration compressor I1, the first condenser 2, the first dry filter 3, the first liquid receiver 4, the first throttle valve 5 and the first evaporator 6 are sequentially connected with copper pipes to form a strictly closed circulation loop I, after pressure test, leak detection and vacuuming, a certain amount of refrigerant I is charged to form a single-stage compression refrigeration system.

[0014] The cascade refrigeration system is mainly composed of a refrigeration compressor II7, a second condens...

Abstract

An ultraslow-temperature air cooler of circulation type is prepared for setting evaporator of single stage compression refrigerating system and evaporator of cascade refrigerating system at front and back in air dust, arranging air filter at air inlet position of said air dust and fan at air outlet position of said air dust, connecting air inlet of air dust to cold air inlet of corollary device and air inlet of air dust to tail-gas outlet of corollary device.

Description

technical field [0001] The invention relates to a cold air device, in particular to a circulation type ultra-low temperature air cooler which circulates wind and blows air at an ultra-low temperature. It belongs to the technical field of refrigeration equipment. Background technique [0002] At present, the known common cold air devices use deep well water or single-stage compression refrigerators to obtain cold air. Generally, the temperature of the low-temperature cold air obtained is above -10°C, which can be used for comfort purposes or industrial purposes required by ordinary processes. However, some industrial operations with high technical requirements need to use colder air at a lower temperature to complete or achieve the desired effect. In addition, the general air cooler adopts the direct-exhaust suction and exhaust method to directly absorb the ambient air, and the cold air is directly discharged into the atmosphere after use. When the temperature of the cold ai...
