Problems solved by technology

However, often operating in a special mode under special working conditions will cause damage to the air conditioner itself
For example, when heating under high temperature conditions, due to the high indoor and outdoor temperatures, the pressure of the air conditioning system is extremely high, and the exhaust temperature and compressor winding temperature are also relatively high, which affects the service life of the compressor.
[0003] In view of the above problems, the frequency conversion air conditioner in the related art adopts the method of reducing the frequency to reduce the pressure of the air conditioning system, but when the pressure is still too high after reducing to the minimum operating frequency, it can only stop the operation of the air conditioner, so that the use effect of the air conditioner and the compression The reliability of the machine cannot be taken into account

Abstract

The invention provides a variable-frequency air conditioner heating control method and device and a variable-frequency air conditioner. The variable-frequency air conditioner heating control method comprises steps as follows: when a heating mode is started and the variable-frequency air conditioner is detected to be under the high-temperature working condition, operating data of the variable-frequency air conditioner and temperature of a mainboard module are periodically collected according to preset time; according to the collected operating data and temperature of the mainboard module, the working state of an outer fan is controlled, and high-temperature protection is realized. According to the scheme, system pressure is reduced by the mode of adjusting the working state of the outer faninstead of blind down-regulation of air conditioner frequency, and therefore, the use effect of the variable-frequency air conditioner can be guaranteed while reliability of a compressor is ensured.Besides, the working state of the outer fan is controlled according to the temperature of the mainboard module of the variable-frequency air conditioner, so that the defect of damage to the variable-frequency air conditioner due to overhigh temperature of the mainboard module because of working state change of the outer fan can be overcome.

Description

technical field [0001] The invention relates to the technical field of frequency conversion air conditioners, in particular to a heating control method and device for frequency conversion air conditioners and a frequency conversion air conditioner. Background technique [0002] In order to meet the diversified needs of users, the air conditioner often needs to work in a special mode in a special working condition. However, often operating in a special mode under special working conditions will cause damage to the air conditioner itself. For example, when heating under high temperature conditions, due to the high indoor and outdoor temperatures, the pressure of the air conditioning system is extremely high, and the exhaust temperature and compressor winding temperature are also relatively high, which affects the service life of the compressor. [0003] In view of the above problems, the frequency conversion air conditioner in the related art adopts the method of reducing the...
