Abstract

A barrel pump refrigeration system, comprising: a liquid storage barrel, a first pump and a first evaporator connected in sequence in a cycle to form a first cycle; the first pump is a fluorine pump; a first pressure regulating valve, a compressor, a condenser, The liquid storage tank, the first pressure regulating valve, the compressor and the condenser are connected cyclically in sequence to form a second cycle. Through the design of the barrel pump refrigeration system, the present invention can form an evaporation temperature above 15°C in the first evaporator, so that under the working conditions of high temperature and high humidity, the refrigeration system will not spontaneously generate redundant dehumidification, which can prevent the air humidity from being too low. , so as to avoid a large amount of humidification compensation and reduce the energy consumption of laboratory operation.

Description
