Abstract

The invention discloses a variable volume type freezing and refrigerating storage two-unit joint operating device and an operating method thereof. The original traditional independent air supply and return system is integrated, two air-cooling evaporators are both connected with air supply ports and air outlets of a freezing chamber and a refrigerating chamber, different combinations are realized through opening and closing of air valves in a two-unit cooperated air supply passage, and a twice-air-supply and twice-air-return operating manner and a twice-air-supply and once-air-return operating manner are respectively realized. Meanwhile, in order to improve the utilization rate of a cold storage, the volume ratio of the freezing chamber to the refrigerating chamber is adjusted in real time through adjusting a heat insulation separation plate between the freezing chamber and the refrigerating chamber, cold capacity distribution is performed on the freezing chamber and the refrigerating chamber according to needs, and fast cooling and optimum storage of food are realized.

Description

technical field [0001] The invention belongs to the field of freezing and refrigeration of cold storage, and more specifically relates to a double-unit joint operation device and an operation method thereof. The air valve in the air channel opens and closes to distribute the air volume to achieve the fastest cooling of the cold storage under different conditions, and combined with the automatic movable insulation partition to achieve the optimal temperature maintenance storage of food. Background technique [0002] After decades of development, my country's refrigeration industry has formed a relatively complete and independent industrial system, and has become one of the pillar industries in the field of food distribution. Cold storage is one of the main methods of food refrigeration. In order to meet the needs of the continuous improvement of people's living standards in our country, my country plans to increase the total capacity of national cold storage to 18.8 million t...
