Air conditioner control method and air conditioner system device

Abstract

The invention relates to the technical field of household appliances, in particular to an air conditioner control method. When an air conditioner is in a heating condition, at least part of refrigerants in a refrigerant circuit are extracted so that the extracted refrigerants cannot participate in work circulation. The invention further provides an air conditioner system device which is used for executing the air conditioner control method. The refrigerant circuit comprises an outdoor heat exchanger, a throttling device, a four-way reversing valve, an indoor heat exchanger and a compressor and further comprises a refrigerant liquid storage device which is used for extracting at least part of the refrigerants in the refrigerant circuit. Due to the fact that a refrigerant liquid storage tank is arranged at an outlet of the indoor heat exchanger in the heating flow direction of the system, redundant refrigerants in the heating condition are stored in the liquid storage tank, the heat exchange efficiency of the indoor heat exchanger in the heating condition is improved, the high pressure of the system is lowered, the power of the compressor is lowered, and finally the energy efficiency of the air conditioner system device is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air conditioner control method and an air conditioner system device. Background technique [0002] The previous air-conditioning performance standards only assessed cooling energy efficiency. However, the current Chinese air-conditioning standards have adopted the annual seasonal energy efficiency (APF) as the energy efficiency assessment index, so the heating energy efficiency also has a great impact on the APF energy efficiency assessment. However, the inventor found in the development and research of air conditioners that when many air conditioners reach the set standard of cooling energy efficiency, they cannot reach the set heating energy efficiency standard (the set heating energy efficiency standard can be the energy efficiency that meets the national standard, or can be It is the internal standard of the enterprise, or the highest energy efficiency standar...
