A refrigerator refrigeration system

Abstract

The invention relates to the field of refrigeration equipment, in particular to a refrigerator refrigeration system capable of automatically adjusting the amount of refrigerant. The refrigeration system of the refrigerator includes a pipeline forming a circuit and a compressor, a condenser, a refrigerant amount regulating device, a capillary tube and an evaporator sequentially arranged on the pipeline. When the refrigeration system needs to increase or decrease the refrigerant, the The sealing part is separated from the opening to open it, the refrigerant in the storage chamber flows into the refrigeration system or the refrigerant in the refrigeration system flows into the storage chamber, and after a set time, the sealing part and The opening snaps to close it. The opening and closing of the refrigerant regulating device is realized by controlling the power on and off of the electromagnet by the control part. The structure is simple and the control is convenient, so that under different external conditions, the load of the compressor can be adjusted in time, and the service life is longer. Energy consumption is optimized for more energy savings and better cooling.

Description

technical field [0001] The invention relates to the field of refrigeration equipment, in particular to a refrigerator refrigeration system capable of automatically adjusting the amount of refrigerant. Background technique [0002] In general, a refrigerator is a device to which a general refrigerating cycle that circulates a refrigerant is applied to supply cold air generated when liquid refrigerant is evaporated to a storage chamber such as a freezer and a refrigerator for a long period of time. Keep food in a fresh state. [0003] The refrigerators in the prior art all include a compressor, a condenser, a capillary tube and an evaporator, which are connected in sequence to form a circuit. Among them, the cooling capacity in the refrigeration system, that is, the amount of refrigerant is mainly matched in the design stage, and the amount of refrigerant in the refrigeration system is fixed during the use of the refrigerator. However, in actual use, due to the inconsistency...

Problems solved by technology

However, in actual use, due to the inconsistency of the ambient temperature and the load of the refrigerator, the operating conditions of the refrigerator are always changing. At this time, the fixed amount of refrigerant in the refrigeration system will lead to low operating efficiency of the refrigerator. , When a lot of things are put in at one time or when the refrigerator is just turned on, the cooling demand is relatively large, and the amount of refrigerant in the system is relatively small compared with the required amount of refrigerant; when the ambient temperature is low or there are few things in the refrigerator, the cooling demand is relatively high. Small, the amount of refrigerant in the system is too much compared to the required amount of refrigerant

[0004] For refrigeration systems, the amount of refrigerant in the system has a greater impact on the cooling effect of the system. Too much or too little refrigerant will increase the workload of the compressor, affect the life of the compressor, and cause large power consumption. , the refrigerator cooling effect is not good
