Heat exchange control method of outdoor unit of air conditioner

Abstract

The invention provides a heat exchange control method of an outdoor unit of an air conditioner. The heat exchange control method of the outdoor unit of the air conditioner is characterized in that theoutdoor unit of the air conditioner comprises an outdoor heat exchanger (2), an air exhaust pipe (1) is arranged indoors, moreover, the outlet end of the air exhaust pipe (1) is arranged at the position of the outdoor heat exchanger (2) or the position close to the outdoor heat exchanger (2) so as to enable exhaust air to be capable of being sent to the position of the outdoor heat exchanger (2);a detection step is performed to be used for detecting the air inlet temperature of the outdoor heat exchanger (2); a judging step is performed, wherein whether the air inlet temperature of the outdoor heat exchanger is in a first preset temperature interval or not is judged; a control step is performed, wherein when the judgment condition is met, a fresh air ventilator is started to send the exhaust air of the air exhaust pipe to the position of the outdoor heat exchanger, and the judgment condition comprises a condition that the air inlet temperature of the outdoor heat exchanger is in thefirst preset temperature interval. According to the heat exchange control method of the outdoor unit of the air conditioner, the indoor exhaust air can be discharged to the position of the outdoor heat exchanger so as to heat or cool the indoor exhaust air, and the heat exchange efficiency of the outdoor unit is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a heat exchange control method for an outdoor unit of an air conditioner. Background technique [0002] With the continuous improvement of people's quality of life, the popularity of air conditioners has become very extensive. A new type of air conditioner formed by fresh air + air conditioners has emerged in response to demand. Fresh air air conditioners can not only meet people's basic requirements for cooling and heating, but also increase People's requirements for the comfort of the environment; but as the environment is getting worse, the requirements for the operation of air conditioners are gradually increasing; [0003] The heat exchange method of the existing household air conditioner outdoor unit uses air-cooled heat exchange, and the heat exchange efficiency is affected by the outdoor ambient temperature. It is too hot, or the heat release efficie...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the heat exchange efficiency of the air conditioning system in the prior art is greatly affected by the outdoor ambient temperature, resulting in very low heat exchange efficiency, thereby providing a heat exchange control system for the outdoor unit of the air conditioner method
