Abstract

The invention discloses a refrigeration device, a refrigeration system and a defrosting control method for the refrigeration device. The refrigeration system comprises a first refrigeration branch, a second refrigeration branch, a third condenser and a switching unit, wherein the first refrigeration branch comprises a first compressor, a first condenser and a first evaporator which are in serial connection; the second refrigeration branch comprises a second compressor, a second condenser and a second evaporator which are in serial connection; the third condenser is connected with the second refrigeration branch; the switching unit is provided with a first interface, a second interface and a third interface; and the switching unit is connected with the second refrigeration branch and is used for selectively causing a refrigerant in the second refrigeration branch to pass by the third condenser, so as to heat the first evaporator through the third condenser. No independently arranged electric heating defrosting device is required by the refrigeration system according to the embedment of the invention, the energy consumption is reduced and the safety of a defrosting process is increased.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigeration equipment, a refrigeration system and a defrosting control method for the refrigeration equipment. Background technique [0002] Existing refrigerators, especially air-cooled refrigerators, usually use heating to defrost the evaporator. The usual method is to use electric heating to defrost, such as installing a steel pipe heater or aluminum tube heating near the evaporator. Defrost using a device or a quartz tube heater, etc. When using this defrosting method, the defrosting power is relatively large, and the energy consumption is relatively large. In addition, when an electrical failure occurs, it is easy to cause a fire, and there are certain safety hazards. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. [0004] In view of this, the present invention needs to pro...
