Air conditioner fluorine deficiency protection method and device and air conditioner

Abstract

The invention provides an air conditioner fluorine deficiency protection method and device and an air conditioner, and relates to the technical field of air conditioners. The air conditioner fluorine deficiency protection method comprises the steps that the temperature values of an evaporator are received; ambient temperature values are received; the difference values between the temperature values of the evaporator and the environment temperature values are calculated, and the temperature difference values are obtained; a first preset temperature value and a second preset temperature value are obtained according to the plurality of temperature difference values, obtained through calculation, of the evaporator under the condition of various environment temperatures; the first preset temperature value is greater than the second preset temperature value, and the air conditioner is controlled to execute fluorine deficiency protection according to the first preset temperature value, the second preset temperature value and the temperature difference values. The air conditioner fluorine deficiency protection device and the air conditioner can both execute the air conditioner fluorine deficiency protection method. According to the air conditioner fluorine deficiency protection method and device and the air conditioner, the technical problem that the air conditioning effect of the air conditioner is affected due to lack of a fluorine deficiency protection method in the prior art can be solved.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner fluorine deficiency protection method, device and air conditioner. Background technique [0002] With the gradual popularization of air conditioners, the competition among various air conditioner manufacturers has become increasingly fierce, and the importance of improving the quality of air conditioners to improve product competitiveness has gradually become prominent. [0003] At present, most heat pump air-conditioning products produced in China do not have the protection function of fluorine deficiency. If fluorine deficiency occurs during the operation of the air conditioner and cannot be protected in time, the refrigerant and lubricating oil will be carbonized due to excessive exhaust temperature and oil temperature. Too high oil temperature will reduce the viscosity of lubricating oil, make the lubrication effect worse, and aggravate the...
