Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an auxiliary device for a complete set of cold storage refrigeration equipment. Background Art

[0002] Generally, cold storage is cooled by refrigeration mechanism, using liquid (ammonia or Freon) with very low vaporization temperature as coolant, so that it evaporates under low pressure and mechanical control conditions, absorbs heat in the storage, and thus achieves the purpose of cooling and cooling. The most commonly used is the compression type refrigerator, which is mainly composed of a compressor, a condenser, a throttle valve and an evaporator. According to the installation method of the evaporator, it can be divided into direct cooling and indirect cooling. Direct cooling installs the evaporator in the cold storage room. When the liquid coolant passes through the evaporator, it directly absorbs the heat in the warehouse and cools it down. Indirect cooling is that the air in the warehouse is sucked into the air cooling device by the blower. After the air is absorbed by the evaporator in the cooling device, it is sent into the warehouse to cool down. The advantages of air cooling are rapid cooling, more uniform temperature in the warehouse, and can take harmful gases such as carbon dioxide generated during storage out of the warehouse.

[0003] The indoor fan of the existing complete set of cold storage refrigeration equipment is basically fixed on the top of the cold storage through a bracket (the principle of cold air descending and hot air rising, the indoor fan is installed at a high place, which is conducive to air circulation and improves refrigeration efficiency). Therefore, the disassembly, assembly or maintenance of the indoor fan of the complete set of cold storage refrigeration equipment requires the use of climbing tools, which is not only troublesome but also has the risk of falling. At the same time, due to the heavy weight of the indoor fan, two people are required to cooperate in lifting it during disassembly and assembly, which has high labor intensity and high operation risk. Therefore, an auxiliary device for the complete set of cold storage refrigeration equipment is proposed. Utility Model Content
