Treatment method and device for refrigerant leakage of air-conditioner

Abstract

The invention discloses a treatment method and device for refrigerant leakage of an air-conditioner. According to the treatment method for refrigerant leakage of the air-conditioner, the air-conditioner comprises a refrigerant detector and a refrigerant system. The treatment method for refrigerant leakage of the air-conditioner includes the steps that by acquiring the refrigerant concentration detected by the refrigerant detector outside a refrigerant system, whether the refrigerant concentration reaches a first preset value and is smaller than a second preset value or not is judged, and the first preset value is smaller than the second preset value; and if the refrigerant concentration reaches the first preset value and is smaller than the second preset value, a power source of the air-conditioner is disconnected through a first circuit breaker. By the adoption of the mode, when refrigerant leakage happens to an indoor unit, the refrigerant concentration in the refrigerant detector can be directly acquired, and when it is judged that the refrigerant concentration reaches the preset value, the power source of the air-conditioner is disconnected through the circuit breaker so that explosion caused by ignition of leaked combustible refrigerant in the using process of the air-conditioner can be avoided.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a method and device for treating refrigerant leakage of an air conditioner. Background technique [0002] With the rapid development of air-conditioning technology, air-conditioning plays an increasingly important role in people's daily life. [0003] However, environmentally friendly refrigerants that meet the requirements of environmental protection, energy saving, and low cost have the disadvantage of being flammable and explosive, which is still a bottleneck restricting the large-scale industrialization of flammable refrigerant air conditioners. The biggest risk is that the leaked refrigerant gas may cause combustion or even explode when the concentration reaches a certain level. And because there are often many home appliances in the room, there is a risk of igniting flammable refrigerant gas. The traditional split wall-mounted air conditioner uses a sealed electric control...
