Problems solved by technology

However, the corresponding leak detection method has not been improved accordingly, that is, the method of one-time judgment on a single air-conditioning parameter should not be used for leak detection, but should be judged by comprehensively applying the parameters of various air-conditioning systems to avoid The misjudgment of air-conditioning refrigerant leakage caused the air-conditioning to repeatedly shut down for protection

Abstract

The invention discloses an air conditioner refrigerant system. The air conditioner refrigerant system comprises an evaporator, a condenser, a four-way valve, a gas-liquid separator and a compressor, wherein a first flowmeter and a second flowmeter are correspondingly arranged at a gas suction port and a gas outlet of the compressor; an outdoor temperature sensor is arranged on the condenser; an air outlet temperature sensor and an air return temperature sensor are arranged on the evaporator; a refrigerant pipeline is composed of a central pipe and an outer sleeve; a hollow cavity is formed between the central pipe and the outer sleeve; and pressure sensors are arranged on the inner walls of the central pipe and the outer sleeve. The air conditioner refrigerant system has the beneficial effects that (1) the judgment accuracy rate of an air conditioner to the refrigerant leakage is higher; and (2) leakage points on an air conditioner pipeline are positioned.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner refrigerant system, a refrigerant leakage detection method and an air conditioner. Background technique [0002] With the improvement of people's living standards, the popularity of air conditioners is getting higher and higher. Facing the large-scale popularization of air conditioners, the maintenance of air conditioners has become correspondingly frequent. There are endless problems with various air conditioners on the market. For the refrigerant leakage problem of air conditioners, no reasonable solution has been found. Now there are various leakages in the market, such as welding leakage of the evaporator of the internal unit, leakage of the connecting pipe, leakage of the condenser of the external unit, and four-way valve pipe. Leaks caused by road breaks, etc., once a leak occurs, the user usually finds out and repairs it when the cooling and heating effec...
