Cold storage heat storage combined constant temperature equipment and control method

Abstract

Provided are a thermostatic apparatus combining cold-storage and heat-storage and a control method therefor. The thermostatic apparatus combining cold-storage and heat-storage comprises a heat preservation box body (1), a compressor (2), an evaporator (3) and a condenser (4). A storage cavity (12) is provided in the heat preservation box body (1), and the heat preservation box body further comprises a cold-storage module and a heat-storage module. The cold-storage module comprises a phase-change cold-storage component (11) and a heat pipe (5). The heat pipe (5) is located in the storage cavity (12). One end portion of the heat pipe (5) is inserted into the phase-change cold-storage component (11) or attached to the surface of the phase-change cold-storage component (11). The evaporator (3) is in thermal conduction with the phase-change cold-storage component (11). The heat-storage module comprises an electric heating component (61) and a phase-change heat-storage component (62). The electric heating component (61) is in thermal conduction with the phase-change heat-storage component (62). The phase-change heat-storage component (62) is located in the storage cavity (12). A phase-change cold-storage material is provided in the phase-change cold-storage component (11). A phase-change heat-storage material is provided in the phase-change heat-storage component (62). The thermostatic apparatus combining cold-storage and heat-storage realizes thermostatic frozen storage, and improves the safety of the cold chain process of medicines and vaccines.

Description

technical field [0001] The invention relates to a refrigeration device, in particular to a combined cold storage and heat storage constant temperature equipment and a control method. Background technique [0002] With the development of modern medicine and the control needs of various epidemics, the application of various new drugs and vaccines has become more and more popular. Such medical materials are usually sensitive to temperature, thus putting forward newer and wider demands for corresponding cold chain logistics. Among them, medical refrigerators of different volumes are important storage equipment for the storage and transportation of such drugs and vaccine materials, and are of great significance to ensuring the safety of drugs and vaccines. [0003] Usually, vaccines must be stored between +2°C and +8°C. However, due to the complex cold chain process of medical materials such as medicines and vaccines, they may encounter various situations, such as vehicle transp...

Problems solved by technology

[0003] Usually, vaccines must be stored between +2°C and +8°C. However, due to the complex cold chain process of medical materials such as medicines and vaccines, they may encounter various situations, such as vehicle transportation, remote villages without normal power supply , a high temperature environment of forty to fifty degrees, a storage environment of about zero degrees, etc.

This complex and changeable environment poses a severe challenge to the constant temperature storage of drugs and vaccines. The annual waste of drugs and vaccines due to temperature is huge.
