Abstract

The invention provides a barrel pump refrigerating system. The system comprises a liquid storage barrel, a first pump and a first evaporator which are sequentially and circularly connected to form a first cycle and a first pressure regulating valve, a compressor and a condenser. The first pump is a fluorine pump. The first pressure regulating valve, the compressor, the condenser and the liquid storage barrel are sequentially and circularly connected to form a second cycle. Through the design of the barrel pump refrigerating system, the evaporation temperature higher than 15 DEG C can be formedin the first evaporator, so that under the working conditions of high temperature and high humidity, the refrigerating system does not generate redundant dehumidification spontaneously, the air humidity can be prevented from being too low, a large amount of humidification compensation is avoided, and the operation energy consumption of a laboratory is reduced.

Description
