Fluorine deficiency detection control method of air conditioner and air conditioner

Abstract

The invention belongs to the technical field of air conditioners, and aims at solving the problem that an existing air conditioner adopts the difference value of exhaust gas temperature of a compressor and the temperature of the outer surface of a compressor body to determine the fluorine deficiency amount, which cannot accurately reflect the true fluorine deficiency condition of the air conditioner. The invention provides a fluorine deficiency detection control method of an air conditioner, and the air conditioner comprises a compressor and an outdoor unit. The fluorine deficiency detection control method comprises the steps of obtaining working current of the compressor; judging whether or not the working current of the compressor is within a preset current range; if not, furthermore obtaining exhaust gas temperature of the compressor and refrigerant temperature of an outlet of the outdoor unit; calculating the difference value between the exhaust gas temperature of the compressor and the refrigerant temperature of the outlet of the outdoor unit; and determining the fluorine deficiency amount of the air conditioner according to the difference value. By means of the fluorine deficiency detection control method of the air conditioner, parameters about the true running condition of the air conditioner can be reflected, thus the accuracy of detecting the fluorine deficiency condition of the air conditioner is greatly improved, and the user experience is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and specifically provides a method for detecting and controlling fluorine deficiency of an air conditioner and the air conditioner. Background technique [0002] An air conditioner is a device that can adjust the temperature of the indoor environment. The air conditioner can cool, heat and dehumidify the room. [0003] During the operation of the existing air conditioner, the content of freon in the air conditioner will gradually decrease due to leakage over time, so that the system of the air conditioner is short of fluorine, and the lack of fluorine will lead to the deterioration of the heat exchange effect of the air conditioner, so It is necessary to replenish freon to the air conditioner in a timely manner. The existing fluorine replenishment method for air conditioners is generally a regular replenishment method, but this method of fluorine replenishment is uncertain. There will b...

Problems solved by technology

[0005] In order to solve the above-mentioned problems in the prior art, that is, in order to solve the difference between the exhaust temperature of the compressor and the outer surface temperature of the body of the compressor used by the existing air conditioner to determine the amount of fluorine deficiency, it cannot accurately reflect the real condition of the air conditioner. For the problem of fluorine deficiency, the present invention provides a fluorine deficiency detection and control method for an air conditioner. The air conditioner includes a compressor and an outdoor unit. The fluorine deficiency detection and control method includes: obtaining the operating current of the compressor; judging the operating current of the compressor Whether it is within the preset current range; if the operating current of the compressor is not within the preset current range, further obtain the discharge temperature of the compressor and the outlet refrigerant temperature of the outdoor unit; calculate the discharge temperature of the compressor and the temperature of the outdoor unit The difference of the outlet refrigerant temperature; according to the difference, determine the amount of fluorine deficiency of the air conditioner
