Novel temperature-humidity control system applied to freezer

Abstract

The invention discloses a novel temperature-humidity control system applied to a freezer. The novel temperature-humidity control system comprises a refrigerating system, a dehumidification and regeneration system and an air supply system; the refrigerating system comprises a compressor, a condenser, a throttle mechanism and a surface air cooler; the dehumidification and regeneration system mainly comprises a moisture absorption regenerator therein; the moisture absorption regenerator is divided into a moisture absorption region and a regeneration region; the air supply system comprises a fan and an air supply and suction mechanism; the compressor, the condenser, the throttle mechanism and the surface air cooler are orderly connected in series; the condenser is arranged within the regeneration region of the moisture absorption regenerator. According to the novel temperature-humidity control system, the refrigerating system is used for cooling and auxiliary dehumidification, the moisture absorption regenerator is used for dehumidification or humidification, and the air supply system is used for enabling air in the freezer to sweep over the moisture absorption regenerator first and then sweep over the surface air cooler of the refrigerating system; the condensation heat of the refrigerating system maintains continuous regeneration of an adsorbent in the regeneration region; and a temperature and a humidity in the freezer are controlled through coordinative work.

Description

Technical field [0001] The invention belongs to the technical field of a preservation box, and specifically is a novel temperature and humidity control system applied to the preservation box. Background technique [0002] At present, the temperature and humidity controlled cool boxes and refrigerators used in the field of medical preservation all adopt refrigeration, cooling and dehumidification. The temperature and humidity in the box are controlled by the refrigeration system and the air supply system. Because the cooling and dehumidification are linked, a heating system must be added In order to maintain the temperature and humidity in the box, due to the linkage of cooling and dehumidification, a heating system must be added to maintain the temperature and humidity in the box. At this time, the energy consumption of cooling and heating at the same time is very large. At the same time, the efficiency of cooling and dehumidification is low in high temperature environments. To m...

Problems solved by technology

[0002] At present, the temperature-controlled and humidity-controlled cool boxes and refrigerators used in the field of medical preservation all use cooling and dehumidification. The temperature and humidity in the box are controlled through the cooling system and the air supply system. Due to the linkage between cooling and dehumidification, a heating system must be added. In order to maintain the temperature and humidity in the box, due to the linkage of cooling and dehumidification, it is necessary to increase the heating system to maintain the temperature and humidity in the box. At this time, the energy consumption of cooling and heating at the same time is very large. To maintain the humidity in the box, it is necessary to lower the temperature of the surface cooler, which increases the hidden danger of frosting on the surface cooler, making the storage box unable to operate stably for a long time
