Embodiment 1

[0049] Such as Figure 1~4 As shown, a combustible refrigerant air conditioner includes a compressor, an air conditioner air inlet 1, an air conditioner internal fan 2, an evaporator 3 and an air conditioner air outlet 4, the air conditioner air inlet 1, an air conditioner internal fan 2, an evaporator 3 and an air conditioner The air outlets 4 are connected through the air duct of the internal unit (not shown in the drawings), and the air outside the air conditioner can enter the internal unit from the air inlet 1 of the air conditioner under the suction of the air conditioner internal fan 2 In the air duct, and after heat exchange with the evaporator 3, it is discharged from the air conditioner through the air conditioner air outlet 4, so as to achieve the purpose of heating or cooling of the air conditioner.

[0050] Further, the flammable refrigerant air conditioner also includes: an indoor fresh air outlet 8 and an indoor return air outlet 10, the indoor fresh air outlet ...

Embodiment 2

[0068] Such as Figure 1~4 As shown, a flammable refrigerant air conditioner control method, the flammable refrigerant air conditioner control method is used for the above-mentioned flammable refrigerant air conditioner. Specifically, the flammable refrigerant air conditioning control method includes the following steps:

[0069] First turn on the first refrigerant detection device 5 and the second refrigerant detection device 6 to detect the leakage of the flammable refrigerant in the indoor atmosphere outside the flammable refrigerant air conditioner and the gas inside the flammable refrigerant air conditioner ;

[0070] When neither the first refrigerant detection device 5 nor the second refrigerant detection device 6 detects leakage of flammable refrigerant, the air conditioner with flammable refrigerant operates in a normal mode;

[0071] When the first refrigerant detection device 5 and / or the second refrigerant detection device 6 detect the leakage of flammable refrig...

Abstract

The invention provides a flammable refrigerant air conditioner and a control method thereof. The flammable refrigerant air conditioner comprises an air conditioner air inlet, an air conditioner inner fan, an evaporator and an air conditioner air outlet, and further comprises a refrigerant detection device capable of detecting the content of flammable refrigerant in surrounding air, an indoor fresh air opening capable of delivering outdoor fresh air into a room, and an indoor air return opening capable of delivering indoor return air to the outside. The flammable refrigerant air conditioner and the control method thereof have the advantages that the structure is simple and convenient to implement, detection for flammable refrigerant leakage is accurate, measures adopted when flammable refrigerant leakage is found are safe, reliable and high in pertinence, the concentration of indoor flammable refrigerant can be quickly and effectively reduced, and indoor combustion and explosion are avoided.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a flammable refrigerant air conditioner and a control method thereof. Background technique [0002] Refrigerants, also known as refrigerants, refrigerants, and refrigerants, are medium substances used to complete energy conversion in various heat engines. The refrigerants commonly used in the current air-conditioning and refrigeration industry, such as R22, not only have obvious damage to the ozone layer, but also have a significant greenhouse effect. According to the "Montreal Protocol", the world will fully restrict the use of refrigerants such as R22 that are not conducive to environmental protection in 2030. Therefore, the development of air conditioners that use environmentally friendly refrigerants to replace traditional refrigerants has become the most urgent task in the refrigeration industry. [0003] However, the emerging environmentally friendly refrigerants ...
