Problems solved by technology

However, under some special conditions, the flow required for cooling and heating of the system will be different, and the flow change cannot be realized in a general system. If the flow change cannot be realized, then for a well-designed refrigeration system, including compressors, Under certain hardware conditions such as indoor and outdoor heat exchangers, the best matching effect of cooling and heating cannot be considered at the same time due to the difference in the optimal refrigerant circulation volume required for cooling and heating. See figure 1

Description

technical field [0001] The invention relates to an air-conditioning system capable of adjusting refrigerant flow, in particular to an air-conditioning system capable of adjusting refrigerant flow during cooling and heating. Background technique [0002] The current air conditioning system generally consists of a compressor, an outdoor heat exchanger, an indoor heat exchanger, a throttling element and a reversing valve to form a refrigeration cycle to achieve the purpose of refrigeration. Through the four-way reversing valve, the system cycle is reversed to form a heat pump system, forming a system. heat effect. However, under some special conditions, the flow required for cooling and heating of the system will be different, and the flow change cannot be realized in a general system. If the flow change cannot be realized, then for a well-designed refrigeration system, including compressors, Under certain hardware conditions such as indoor and outdoor heat exchangers, the bes...
