The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Referring to Fig. 1-Fig. 3, air-conditioner, the off-premises station that comprises control assembly 8, is positioned at the indoor set of indoor and is positioned at the outside, indoor set and off-premises station connect into closed circuit through pipeline, and indoor and outside are divided with wall.
Be provided with the leak detector 5 that is used to detect flammable refrigerant concentration near the electric-controlled box of indoor set and/or near the air outlet; Air-conditioner also comprises air interchanger 1; This air interchanger 1 comprises the ventilation blower fan that has the motor 11 of taking a breath; The air inlet of air interchanger 1 is provided with screen pack 13 and fly net 14, the air outlet of air interchanger 1 be provided with the rotation of ventilation motor 11 open, with ventilation motor 11 stop and the baffle plate 16 of closing.
In the present embodiment, air interchanger 1 is arranged in the casing of indoor set.Indoor machine of air-conditioner comprises air interchanger 1, ventilation flexible pipe 2, buzzer 3, evaporimeter 4, leak detector 5, interior machine base 6, indoor fan motor 7, control assembly 8, front plane frame 9 and centrifugation blade 10.Wherein, as shown in Figure 2, air interchanger comprises ventilation motor 11, ventilation shell 12, screen pack 13, fly net 14, centrifugal wind wheel 15 and baffle plate 16.The off-premises station of air-conditioner comprises compressor 17, outdoor fan motor 18.
Air-conditioner is when normal operation; When leak detector 5 detect indoor set or indoor set around flammable leakage of refrigerant takes place after, ventilation motor 11 starts, baffle plate 16 is opened; Through ventilation flexible pipe 2 the new wind of outside is delivered to indoorly, reduced the flammable refrigerant concentration in the room.
