Refrigerating system for refrigerator

Abstract

The invention relates to the field of refrigerating equipment, in particular to a refrigerating system capable of automatically adjusting the refrigerant amount for a refrigerator. The refrigerating system for the refrigerator comprises a pipeline forming a loop, and a compressor, a condenser, a refrigerant amount adjustment device, a capillary pipe and an evaporator sequentially arranged on the pipeline, wherein when a refrigerant needs to be increased or reduced in the refrigerating system, a sealing part is separated from an opening so as to open the opening, a refrigerant in a storage cavity flows into the refrigerating system or the refrigerant in the refrigerating system flows into the storage cavity, and after a setting time, the sealing part fits to the opening so as to close the opening. The refrigerant amount adjustment device is switched on and switched off through the control on power on and power off of an electromagnet by a control piece, the refrigerant system for the refrigerator is simple in structure and convenient to control, under different externa conditions, a load of the compressor can be timely adjusted, the service life is long, and the energy consumption of the refrigerator is optimized, so that more energy can be saved, and a refrigerating effect is better.

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...

AI Technical Summary

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
