Air conditioner control method and air conditioner

Abstract

The invention provides an air conditioner control method and an air conditioner. The air conditioner control method comprises the following steps that the compressor frequency and the operating powerare detected, the operating power and a preset power value corresponding to the compressor frequency are compared, if the operating power is less than the preset power value corresponding to the compressor frequency, a refrigerant lacking signal is output; and otherwise, the air conditioner continues to operate. The air conditioner can realize the air conditioner control method. According to the air conditioner control method and the air conditioner, the compressor frequency and the operation power are detected, and the operating power is compared with the preset power value corresponding to the compressor frequency, so that whether refrigerants are in lack or not is judged, judgment is more accurate, and the false alarm situation is effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner control method and an air conditioner. Background technique [0002] At present, the fluorine-deficiency protection control of the air conditioner usually detects several control parameters of the system, and when the operating parameters are met, the user is prompted to report a fluorine-deficiency protection failure. [0003] These parameters include system exhaust temperature, suction temperature, indoor heat exchanger inlet and outlet air temperature difference, outdoor heat exchanger inlet and outlet air temperature difference, expansion valve opening, etc. When the system really lacks fluorine, these parameters may be appropriate; but there is also the possibility of false alarms, such as some abnormal operation stop valves not opening, when the temperature changes, and when the frequency is low. [0004] False alarms will occur duri...

AI Technical Summary

Problems solved by technology

When the system really lacks fluorine, these parameters may be appropriate; but there is also the possibility of false alarms, such as some abnormal operation shut-off valves not opened, when the temperature changes, when running at low frequency, etc.

[0004] False alarms will occur during some abnormal operations. At the same time, if some control parameters take a long time to reach the set value, when the system actually lacks fluorine, it will take a long time to report the fault, which will affect the reliability of the system. sex
