Abstract

The invention relates to the technical field of air conditioning, in particular to a control method of an air conditioner. The present invention aims to solve the problem of poor heating effect existing in the existing air conditioner. For this purpose, the control method of the present invention includes: obtaining the outdoor ambient temperature during heating operation; comparing the size of the outdoor ambient temperature and the temperature threshold; when the outdoor ambient temperature is less than the temperature threshold, obtaining the temperature of the heat exchange pipe section; According to the temperature of the pipe section, the opening and closing of several subcooling valves can be selectively adjusted to adjust the effective length of the subcooling pipe section. The above control method can effectively improve the heating effect of the air conditioner, improve the heating energy efficiency of the air conditioner, inhibit frost formation and effectively defrost.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method of an air conditioner. Background technique [0002] Traditional inverter air conditioners only assess cooling energy efficiency and power, and use cooling energy efficiency as the energy efficiency rating standard, but have no requirements for heating power and capacity. Therefore, when developing inverter air conditioners, R&D personnel generally take the best cooling energy efficiency as the design principle. However, with the introduction and implementation of the new national energy efficiency standards, the cooling, heating power and energy efficiency of inverter air conditioners are all included in the assessment scope, and heating energy efficiency has a great impact on the overall energy efficiency of air conditioners. Its heating energy efficiency has become one of the most critical tasks in the current industry. [0003] In addition, in the p...
