Dry air curtain blocking evaporator frosting refrigerator energy-saving facility

Abstract

The invention discloses an energy-saving facility for a dry air curtain blocking evaporator frosting cold storage, specifically comprising an air curtain air curtain machine and an isothermal dehumidifier; wherein the air curtain machine located outside the cold storage is called an external air curtain machine , used to block high-temperature and high-humidity air from flowing into the cold storage; the air curtain machine located inside the cold storage is called an internal air curtain machine, and the indoor part of the isothermal dehumidifier is also located inside the cold storage. The internal air curtain machine is used with an isothermal dehumidifier. In order to further block and absorb the hot and humid air in the flow field of the warehouse door; the air in the cold storage is first dehumidified through the isothermal dehumidifier, and then blown out by the internal air curtain machine and returned to the cold storage. The cold storage energy-saving facility of the present invention can absorb and remove the water vapor and excess water in the cold storage during defrosting, prevent and reduce the frosting of the evaporator in the cold storage, reduce the number of defrosting in the cold storage, and increase the COP value of the evaporator and the refrigeration system , so as to achieve the purpose of reducing the energy consumption of the cold storage and improving the energy efficiency of the cold storage.

Description

technical field [0001] The invention relates to the field of energy saving and environmental protection technology, and more particularly relates to an energy-saving facility for a dry air curtain blocking the frosting of an evaporator and a cold storage. Background technique [0002] Frosting in cold storage has always been a major problem in the efficiency of cold storage operation. The energy consumption of defrosting in cold storage operation accounts for as much as one-third of the total energy consumption of cold storage. For many years, the research of the industry has always taken the technology of how to defrost and defrost as a breakthrough method, but in fact it only treats the symptoms but not the root cause, so it has had little effect so far. [0003] A large part of the energy consumption of the existing cold storage is consumed in the defrosting process of the refrigeration system and the inefficient operation of the refrigeration system, and the rest is used...

AI Technical Summary

Problems solved by technology

[0029] 1. The daily operating energy consumption of the refrigeration system is 2278.4kw / h

[0030] 2. The daily defrosting energy consumption of the defrosting system is 810kw / h

[0032] In addition, due to the low temperature of the cold storage, traditional heating dehumidification and condensation dehumidification cannot work normally in the cold storage environment, so the cold storage dehumidification has always been an intractable enemy in the industry

[0033] To sum up, there is still a lack of a device in the field that can help dehumidify the cold storage, reduce frosting in the cold storage, thereby reduce the number of defrosting, and reduce the energy consumption of the cold storage
