Jacket type energy-saving refrigeration house

Abstract

The invention discloses a jacket type energy-saving refrigeration house. The jacket type energy-saving refrigeration house is characterized in that a mother warehouse system is a cavity defined by a heat preservation structure layer, a sub-warehouse system is a child warehouse heat conduction structure built in the heat preservation structure layer through metal materials with good heat conductionperformance, a gap exists between the child warehouse heat conduction structure and the heat preservation structure layer, the child warehouse heat conduction structure is a pentahedron without a bottom face, and an evaporator or an air cooler of a refrigerating system is arranged in an interlayer formed by the mother warehouse system and the sub-warehouse system. According to the jacket type energy-saving refrigeration house, the heat exchange efficiency of the evaporator is improved, meanwhile, defrosting does not need to be considered, and additional power consumption cannot be increased.

Description

technical field [0001] The present invention relates to the field of a jacket type cold storage system, more specifically, relates to a jacket type cold storage system. Background technique [0002] For low-temperature storage, frosting on the evaporator is a big problem. Frosting on the evaporator affects the heat transfer efficiency of the refrigeration system, and eventually the refrigeration cannot meet the requirements for cooling the environment. At the same time, for some systems, it may also be Faced with the phenomenon of compressor returning air with liquid, it may seriously cause liquid shock, resulting in damage to the compressor or poor performance, etc. Therefore, system defrosting is inevitable for such a system whose evaporation temperature is lower than 0°C. Nowadays, the commonly used defrosting methods mainly include three forms: electric defrosting, water defrosting and hot fluorine defrosting: the electric defrosting operation consumes a lot of power, wh...

[0002] For low-temperature storage, frosting on the evaporator is a big problem. Frosting on the evaporator affects the heat transfer efficiency of the refrigeration system, and eventually the refrigeration cannot meet the requirements for cooling the environment. At the same time, for some systems, it may also be Faced with the phenomenon of compressor returning air with liquid, it may seriously cause liquid shock, resulting in damage to the compressor or poor performance, etc. Therefore, system defrosting is inevitable for such a system whose evaporation temperature is lower than 0°C

Nowadays, the commonly used defrosting methods mainly include three forms: electric defrosting, water defrosting and hot fluorine defrosting: the electric defrosting operation consumes a lot of power, which leads to an increase in operating costs and also releases a large amount of heat to the environment. , which virtually increases the heat load of the cold room, resulting in excessive fluctuations in the ambient temperature; the application environment of the water flushing frost system is limited, and it mainly applies to some conditions where the ambient temperature tends to be around 0°C, and it will also bring Injecting a part of the heat load, the most important thing is that water flushing has a great disadvantage. It may bring bacteria into the evaporator or the environment through the defrosting water, which is very detrimental to freshness; hot fluorine flushing is harmful to The requirements for system piping and valve parts are too high, resulting in increased engineering costs, and at the same time, too much heat will be brought into the environment, increasing the environmental heat load, resulting in excessive fluctuations in ambient temperature and other disadvantages

The defrosting mentioned above all bring many unfavorable factors to the cold room.
