Movable pre-cooling air-conditioning and fresh-keeping integrated machine

Abstract

The invention discloses a movable pre-cooling air-conditioning and fresh-keeping integrated machine. The machine comprises a storage body, an equipment chamber, a heat preservation partition wall and a vacuum system, wherein a pre-cooling chamber and a storage chamber are arranged in the storage body, a refrigerating system and an air-conditioning control system are arranged in the equipment chamber, and the output end of the refrigerating system is installed in the pre-cooling chamber and the storage chamber; the output end of the air-conditioning control system is mounted in the storage chamber; the heat preservation partition wall is slidably arranged between the pre-cooling chamber and the storage chamber, sealing structures abutting against inner walls of the storage body are arranged on the two sides of the peripheral edge of the heat preservation partition wall, and the peripheral edges of the sealing structures, the peripheral edge of the heat preservation partition wall and the inner walls of the storage body are matched to form a sealed space; an operating mechanism is installed on the side, located in the storage chamber, of the heat preservation partition wall, and the output end of the operating mechanism is connected with the sealing structures; and the vacuum system is installed in the heat preservation partition wall and can vacuumize the sealed space. The pre-cooling air-conditioning and fresh-keeping integrated machine can adjust the relative space of a refrigeration storage and the air-conditioning chamber, the sealing performance between the refrigeration storage and the air-conditioning chamber is good, the heat preservation effect is good, and the fresh-keeping effect is good.

Description

technical field [0001] The invention relates to the technical field of controlled atmosphere warehouses, in particular to a mobile pre-cooling and controlled atmosphere preservation integrated machine. Background technique [0002] At present, the controlled atmosphere warehouse, also known as the controlled atmosphere storage warehouse, is the most advanced method of fresh-keeping and storage of fruits and vegetables. It is on the basis of cold storage, which increases the adjustment of gas components. By controlling the temperature, humidity, carbon dioxide, oxygen concentration and ethylene concentration in the storage environment, it inhibits the respiration of fruits and vegetables, delays their metabolic process, and better keeps fruits and vegetables fresh. Degree and commerciality, prolong the storage period and preservation period of fruits and vegetables. Usually, controlled atmosphere storage can prolong the storage period by 0.5-1 times compared with ordinary co...

Problems solved by technology

[0004] However, the internal refrigerated space and the air-conditioned storage space in the commercial mobile cold storage with both refrigeration and air-conditioning functions are relatively unadjustable. The main reason is that the freezing temperature in the refrigerator is 18~ lower than that in the air-conditioned storage. 33°C; if it is designed as a space-adjustable structure, it will easily lead to insufficient sealing between the cold storage and the air-conditioning storage, which will easily lead to a decrease in the insulation effect of the cold storage, and the temperature of the air-conditioning storage is likely to be too low, which will make this The fresh-keeping quality of similar multi-functional mobile cold storage has declined
