Absorption frost prevention system for refrigeration house and absorption frost prevention method

Abstract

The invention relates to an absorption frost prevention system for a refrigeration house. The absorption frost prevention system for the refrigeration house comprises two basic units. The basic units comprise air inlet valves, low-temperature absorption beds, desorption reflux refrigeration valves, high-temperature absorption beds, air exhausting valves, reflux refrigeration valves and gas returning valves. The air inlet valves, the low-temperature absorption beds, the desorption reflux refrigeration valves, the high-temperature absorption beds, the air exhausting valves, the reflux refrigeration valves and the gas returning valves are sequentially connected. Absorption agent channel layers and reflux refrigeration channel layers are arranged in the low-temperature absorption beds. The absorption agent channel layers are connected with the air inlet valves and the desorption reflux refrigeration valves. The reflux refrigeration channel layers are connected with the reflux refrigeration valves and the gas returning valves. The air inlet valves are connected with an air source of the refrigeration house. The air returning valves are connected with air distributing openings of the refrigeration house through evaporation devices. The air exhausting valves are connected with the outside environment. Absorption bed heat exchangers and high-temperature absorption agents are arranged in the high-temperature absorption beds. The desorption reflux refrigeration valves are further provided with third outlets. The third outlets are connected with the reflux refrigeration valves of the other basic unit. The invention further provides an absorption frost prevention method for the refrigeration house. The absorption frost prevention system for the refrigeration house and the absorption frost prevention method can use solar energy or low-temperature wasted heat to achieve frost prevention of the refrigeration house, capabilities of the refrigeration house are optimized, energy is saved, environment is protected and power consumption of the system and operation cost are reduced.

Description

technical field [0001] The invention belongs to the technical fields of refrigeration technology and air conditioning, and particularly relates to an adsorption frost protection system and an adsorption frost protection method for a refrigerator. Background technique [0002] In recent years, with the development of international trade and the continuous improvement of people's living standards in our country, the demand for various fresh products is increasing, and the requirements for product preservation are also getting higher and higher. my country's cold storage generally has the phenomenon of high energy consumption, which leads to the extra consumption and waste of a large amount of fossil fuels. The phenomenon that the evaporator frost is more serious is also a major problem in the operation of the cold storage. At present, most of the defrosting technologies in cold storage have problems such as high energy consumption and large fluctuation of storage temperature,...

AI Technical Summary

Problems solved by technology

High energy consumption is common in cold storage in my country, resulting in a large amount of additional consumption and waste of fossil fuels

The serious frosting of the evaporator is a major problem in the operation of the cold storage.

At present, most cold storage defrosting technologies have problems such as high energy consumption and large storage temperature fluctuations, which are not conducive to the efficient and stable operation of cold storage; on the other hand, most of the anti-frost technologies are in the experimental research stage, and it will take a long time to realize industrial scale application. way, and this type of technology generally still needs the cooperation of defrosting technology
