Problems solved by technology

[0004] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the protection limit requirements of the existing air conditioner when the external environment temperature is high, the operable speed of the inverter compressor is reduced, and the cooling effect of the air conditioner is poor. The present invention provides Provided is a compressor control method for an air conditioner, the air conditioner includes a variable frequency compressor, and the compressor control method includes: obtaining a first outdoor ambient temperature when the air conditioner operates with variable frequency for cooling; if the If the first outdoor ambient temperature is always higher than the first preset temperature within the first set time, the speed of the variable frequency compressor is obtained; if the speed of the variable frequency compressor is lower than the set speed, the air conditioner fixed frequency operation

Abstract

The invention belongs to the technical field of heat exchange equipment, and particularly relates to a compressor control method of an air conditioner. The compressor control method of the air conditioner aims to solve the problems that the protection limiting requirement of an air conditioner in the prior art, when the external environment temperature is high, reduces the running rotating speed of a variable-frequency compressor, and the refrigeration effect of the air conditioner is poor. According to the compressor control method of the air conditioner, when the air conditioner has the rotating speed limiting requirement on the variable-frequency compressor, the variable-frequency operation mode of the air conditioner is switched into a fixed-frequency operation mode, so that the air conditioner with the large refrigeration requirement cannot cause overload damage to components of the air conditioner due to the fact that the rotating speed of the variable-frequency compressor is toolarge, the rotating speed limiting requirement of the compressor is eliminated, and meanwhile, good refrigeration of the air conditioner is guaranteed through the fixed-frequency operation mode, theair conditioner can be switched between the variable-frequency operation mode and the fixed-frequency operation mode according to the actual operation requirement, and the overall operation effect ofthe air conditioner in various operation environments is optimized.

Description

technical field [0001] The invention belongs to the technical field of heat exchange equipment, and in particular relates to a compressor control method of an air conditioner. Background technique [0002] The compressor of the inverter air conditioner has different maximum and minimum speed values ​​at different ambient temperatures. Generally speaking, when the external ambient temperature is higher, the cooling demand of the air conditioner is greater, so the load of the whole unit is greater and the current is greater. In view of this, in order to protect the compressor and the electronic control devices of the air conditioner, when the external ambient temperature is higher, the maximum speed of the inverter compressor set by the air conditioner is lower. The protection limitation of the air conditioner causes the speed of the inverter compressor to change only within a small speed range, resulting in a higher temperature of the indoor heat exchanger and poor operation...
