Problems solved by technology

[0003] In practical applications, when the air conditioning system operates in a low-temperature and high-humidity environment that is prone to frost, due to the defrosting operation, it is easy to have a problem of large temperature and humidity fluctuations at the installation position of the sensor that detects the temperature of the refrigerant in the outdoor heat exchanger , which in turn can easily lead to sensor failure
When the sensor has faults such as short circuit, open circuit, and temperature drift, the air conditioner cannot complete the defrosting action normally, and the unit capacity and energy efficiency will decrease due to the accumulation of frost layer, and in severe cases, the air conditioning system will not be able to operate normally

Abstract

The present invention provides a defrosting control method of an air conditioner, a defrosting control device and an air conditioner, wherein the defrosting control method of an air conditioner includes: when the air conditioner is running in a heating mode, judging whether the first The defrosting control logic performs defrosting control on the air conditioner; if it is determined that the defrosting control can be performed on the air conditioner through the first defrosting control logic, then the air conditioner is controlled by the first defrosting control logic defrosting control of the air conditioner; if it is determined that the defrosting control of the air conditioner cannot be performed through the first defrosting control logic, defrosting control of the air conditioner is performed through the second defrosting control logic. The technical scheme of the present invention makes it possible to continue defrosting control of the air conditioner through the standby defrosting control logic when the default defrosting control logic of the air conditioner fails, thereby ensuring the continuous heating operation of the air conditioner system and ensuring the normal operation of the unit. The heat supply is beneficial to improve the user experience.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner defrosting control method, an air conditioner defrosting control device and an air conditioner. Background technique [0002] At present, a variety of defrosting control methods have been proposed in the technologies related to air conditioners, but based on cost considerations, it is usually based on detecting the temperature of the refrigerant in the outdoor heat exchanger to control whether the air conditioner enters and exits defrosting. [0003] In practical applications, when the air conditioning system operates in a low-temperature and high-humidity environment that is prone to frost, due to the defrosting operation, it is easy to have a problem of large temperature and humidity fluctuations at the installation position of the sensor that detects the temperature of the refrigerant in the outdoor heat exchanger , which can easily lead to sensor f...
