Abstract

The invention provides an automatic regulation control method and device of a refrigerant amount, and an air conditioner, and belongs to the field of air conditioning. The automatic regulation deviceof the refrigerant amount comprises a compressor, an indoor heat exchanger, an orifice union and an outdoor heat exchanger that are sequentially communicated and form a refrigerant circulation loop, and further comprises a refrigerant amount regulation loop communicated with the refrigerant circulation loop, wherein the refrigerant amount regulation loop and the orifice union are arranged in parallel. Compared with the prior art, the automatic regulation control method and device of the refrigerant amount can control the circulating refrigerant amount in an air-conditioning system, ensures theoptimal refrigerant amount for the operation of the air-conditioning system and achieves heat exchange efficiency to the greatest extent.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a method and device for automatically adjusting and controlling the amount of refrigerant, and an air conditioner. Background technique [0002] The refrigerant in the air conditioner circulates in the system to realize the cooling operation or heating operation mode; and to achieve the best cooling or heating capacity, it is necessary to complete the evaporation in the heat exchanger. Therefore, the air conditioner When the system operates under different installation conditions and working conditions, the amount of refrigerant required is different. For example, when the indoor unit and the outdoor unit use long connecting pipes, the air-conditioning system requires a large amount of refrigerant. At this time, an appropriate amount of refrigerant needs to be added; Or the heating effect is not good, and the operation energy efficiency is low. Contents of the...
