Problems solved by technology

However, it is obvious that although the above two methods can reduce the explosion risk caused by refrigerant leakage, fundamentally speaking, they cannot completely eliminate this risk, and cannot completely solve the potential safety hazards that may arise from indoor leakage.

Embodiment 1

[0039] Such as figure 1 As shown, a safe heat exchange system for a flammable and explosive refrigerant air conditioner in a heating state includes an outdoor unit 1 and an indoor unit 2. The outdoor unit 1 includes a compressor 8, a cooling and heating reversing device 9, a throttling The device 10 and the outdoor heat exchanger 11; also includes an intermediate thermal coupling unit, the intermediate thermal coupling unit includes the indoor heat exchange device 4;

[0040] The throttling device 10 is connected between the first outdoor refrigerant inlet and outlet of the indoor heat exchange device 4 and the first refrigerant inlet and outlet of the outdoor heat exchanger 11 through the outdoor refrigerant circulation pipe 3, and the cooling and heat reversing device 9 passes through the outdoor refrigerant circulation pipe 3. It is connected with the second outdoor refrigerant inlet and outlet of the indoor heat exchange device 4, the second refrigerant inlet and outlet of...

Embodiment 2

[0046] Such as figure 2 As shown, a safe heat exchange system for an air conditioner with flammable and explosive refrigerants in a refrigeration state has the same structure as that of Embodiment 1, and its cold and heat reversing device 9 is switched to the second outdoor refrigerant inlet and outlet of the indoor heat exchange device 4. A state in which the suction port of the compressor 8 communicates with the suction port of the compressor 8 and the discharge port of the compressor 8 communicates with the second refrigerant inlet and outlet of the outdoor heat exchanger 11 .

[0047] When working, the high-temperature, flammable and explosive refrigerant gas compressed by the compressor 8 is reversed by the cold-heat reversing device 9, first flows into the outdoor heat exchanger 11 for condensation and heat exchange, and then throttling through the throttling device 10 after condensation. The throttled low-temperature flammable and explosive refrigerant gas-liquid mixtu...

Embodiment 3

[0049] Such as image 3 As shown, a safe heat exchange system for a flammable and explosive refrigerant air conditioner in a heating state includes an outdoor unit 1 and an indoor unit 2. The outdoor unit 1 includes a compressor 8, a cooling and heating reversing device 9, a throttling The device 10 and the outdoor heat exchanger 11; also includes an intermediate thermal coupling unit, the intermediate thermal coupling unit includes the indoor heat exchange device 4;

[0050] The throttling device 10 is connected between the first outdoor refrigerant inlet and outlet of the indoor heat exchange device 4 and the first refrigerant inlet and outlet of the outdoor heat exchanger 11 through the outdoor refrigerant circulation pipe 3, and the cooling and heat reversing device 9 passes through the outdoor refrigerant circulation pipe 3. It is connected with the second outdoor refrigerant inlet and outlet of the indoor heat exchange device 4, the second refrigerant inlet and outlet of...

Abstract

The invention belongs to the technical field of air conditioner equipment, and particularly discloses a safety heat exchange system capable of meeting the indoor air conditioner needs and basically eradicating safety risks brought by leakage of flammable and combustible refrigerants and an air conditioner including the safety heat exchange system. The safety heat exchange system for the flammableand combustible refrigerant air conditioner comprises an outdoor machine unit and an indoor machine unit, and further comprises an intermediate thermal coupling unit, the intermediate thermal couplingunit comprises an indoor heat exchange device, the intermediate thermal coupling unit is arranged, the indoor heat exchange device included in the intermediate thermal coupling unit is used for coupling the outdoor machine unit and the indoor machine unit, cold and heat of flammable and combustible refrigerants in an outdoor circulation system can be transmitted to safety refrigerants in an indoor circulation system, the safety refrigerants are used for supplying the cold and the heat to an indoor loop heat pipe unit, on one hand, the indoor air conditioner needs can be met, and on the otherend, the safety risks caused by leakage of the flammable and combustible refrigerants can be basically eradicated.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning equipment, and in particular relates to a safety heat exchange system and an air-conditioner for inflammable and explosive refrigerant air-conditioning. Background technique [0002] As a kind of indoor temperature control equipment, the air conditioner has been popularized in consumers' families. The split-type air conditioners commonly used now include indoor units and outdoor units. The refrigerant of the air conditioner is driven by the compressor to circulate heat in the indoor and outdoor heat exchangers, and there are inevitably many processing welding points on the heat exchangers. Therefore, once Solder joint leakage may cause refrigerant leakage indoors or outdoors. Outdoor leakage will not cause excessive refrigerant concentration due to the large space, while indoor leakage may cause excessive refrigerant concentration. For some flammable and explosive refrigerants, such as F...
