Problems solved by technology

[0012] However, the conventional refrigerant leakage method only judges whether the measured temperature of the indoor heat exchanger is higher than the specified value, so it is difficult to sense whether the refrigerant is leaking or not based on the measurement error and the operating state of the air conditioner.

Abstract

This invention is refrigerants leakage perception method of air conditioner. It includes: the first step: whether air conditioner driving time has passed the set time is judged; temperature measurement step: when air conditioner driving time has passed the set time, the heat exchanger temperature sensor and absorbed air temperature sensor measure the temperature. The heat exchanger temperature sensor is set on the indoor heat exchanger. The absorbed air temperature sensor is set on the indoor machine; comparison step: the temperature difference between indoor heat exchanger (Te) and absorbed air (Ta) is compared with the stored data in controlling part; refrigerants leakage judging step: when the temperature difference is smaller than the set data, then the refrigerants have already leaked.

Description

technical field [0001] The present invention relates to a method for sensing refrigerant leakage of an air conditioner, in particular to an air conditioner that detects refrigerant leakage by measuring the temperature of the refrigerant conduit of the indoor heat exchanger and the temperature difference (ΔT) at the suction inlet of the indoor unit refrigerant leak detection method. Background technique [0002] Figure 8 It is a structural diagram of an air conditioner according to the prior art. [0003] Such as Figure 8 As shown, the air conditioner according to the prior art includes a compressor 1 , an outdoor heat exchanger 2 , an indoor heat exchanger 4 and an expansion valve 3 . [0004] Here, the refrigerant is used as a medium for operating the air conditioner, and the air conditioner drives a heating cycle or a cooling cycle according to a refrigerant circulation direction. [0005] In addition, when the refrigerant circulating in the air conditioner is driven f...
