Further, the first communication component 330 in switch controlling device 3 and second communication parts 331 can be WIFI communication component simultaneously, or can be bluetooth communication means simultaneously, or can be twireless radio-frequency communication parts simultaneously.It should be noted that, if be arranged on second controller 311 in the positional distance switch controlling device 3 in space and second communication parts 331 and relay 32 when nearer at air-conditioner 2, for example, when the second controller 311 in air-conditioner 2 and switch controlling device 3 and second communication parts 331 and relay 32 are arranged in a room, the first communication component 330 and second communication parts 331 can be near field communication component simultaneously.
Further, when reality is used, the control end of above-mentioned switch controlling device 3 middle controllers 31 can also be for being connected with the first end of ventilation unit 4, wherein, the second end of ventilation unit 4 can be for being connected with power supply 1, be that ventilation unit 4 can be connected directly to power supply 1, and powered by power supply 1, and without switch controlling device 3, be connected to power supply 1, thereby the folding of the circuit at ventilation unit 4 places (disconnecting or closure) is not subject to the control of switch controlling device 3, but whether the startup of ventilation unit 4 is subject to the control of the controller 31 in switch controlling device 3.Ventilation unit 4 can be leaked to indoor combustible refrigerant for getting rid of air-conditioner 2.Because ventilation unit 4 and switch controlling device 3 are connected directly to power supply 1, while therefore controlling the circuit disconnection at air-conditioner 2 places under the effect of switch controlling device 3 in control signal, ventilation unit 4 and switch controlling device 3 are still connected to power supply 1, and obtain electric, therefore the circuit at ventilation unit 4 places is still closed, and switch controlling device 3 enters deadlock state.Like this, can on the controller 32 in switch controlling device 3, hand push button be set, this hand push button can be for when switch controlling device 3 enters deadlock state, by artificial mode, press this hand push button, and after this hand push button is pressed, it can Closing Switch control device 3, thereby open room air conditioner 2, normally works.
Further, the detector 30 in above-mentioned switch controlling device 3 can be sensor.Wherein, this sensor can be for detecting in real time the concentration of airborne combustible refrigerant, or it can be for detecting the concentration of the combustible refrigerant in primary air every preset time period.Wherein, when the concentration that combustible refrigerant in air detected when sensor surpasses preset value, this sensor can produce detection signal, and the concentration that combustible refrigerant in air detected when sensor is while surpassing preset value, and this sensor can not produce detection signal.Like this, can only when leaking, combustible refrigerant produce detection signal, the burden of mitigation system, the control efficiency of raising system.
It should be noted that, in the present invention, switch controlling device 3 can be air switch control device.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
