Special refrigerated cabinet for refrigeration near freezing point of fruits and vegetables and temperature control method for the refrigerated cabinet

Abstract

The invention relates to the field of refrigerating technology and fruit and vegetable fresh keeping, in particular to a special refrigerated cabinet for near-freezing-point refrigeration of fruits and vegetables and a temperature control method for the refrigerated cabinet. The special refrigerated cabinet for near-freezing-point refrigeration of the fruits and vegetables comprises a cabinet door (3), a cabinet body (16) and a refrigeration device. The cabinet body (16) is a closed rectangular container with an opening end. The refrigeration device comprises an insulating layer (1), a refrigerating plate (2), a first heat isolation layer (5) and a second heat isolation layer (6). A first channel (21) is formed between the second heat isolation layer (6) and the first heat isolation layer (5), and a second channel (22) is formed between the first heat isolation layer (5) and the refrigerating plate (2). The special refrigerated cabinet for near-freezing-point refrigeration of the fruits and vegetables is high in temperature control precision, uniform in storage chamber temperature and high in reliability and has an overtemperature early warning mechanism. Two sets of temperature control measures are designed, and the special refrigerated cabinet for near-freezing-point refrigeration of the fruits and vegetables and the temperature control method for the refrigerated cabinet have the advantages that the temperature control precision is high, the temperature in a storage room is uniform, overtemperature early warning can be achieved, and reliability is high.

Description

technical field [0001] The invention relates to the fields of refrigeration technology and fresh-keeping of fruits and vegetables, in particular to a special refrigerator for refrigeration near freezing point of fruits and vegetables and a temperature control method of the refrigerator. Background technique [0002] At present, the commonly used commercial fruit and vegetable storage methods are mostly ordinary refrigeration, controlled atmosphere refrigeration and composite fresh-keeping methods based on refrigeration. These storage methods have basically realized the annual storage of pome fruits such as apples and pears, but cannot meet the long-term storage requirements of stone fruits such as peaches and apricots and other fruits. This is an urgent problem to be solved in the field of fruit and vegetable preservation. [0003] In recent years, as an emerging technology, the near-freezing refrigeration technology of fruits and vegetables has attracted the attention of s...
