Fig. 1 shows flow chart according to an embodiment of the invention.In Fig. 1:
Step S100: pressure switch is turn-offed, and makes air-conditioning out of service.Wherein, if pressure switch is a high-pressure switch, then when the pressure of the position of this pressure switch institute sensing was excessive, air-conditioning was out of service.Wherein, air-conditioning is out of service to include but not limited to that air-conditioning stops to heat and/or air-conditioning stops refrigeration, and the air-conditioning functional module that refers to air-conditioning out of service quits work, and control chip still continues operation.
If pressure switch is the low pressure switch, then when the pressure of the position of this pressure switch institute sensing was too small, air-conditioning was out of service.Preferably, the control chip in the air-conditioning senses pressure switch and turn-offs, and makes air-conditioning out of service through sending signal to air-conditioning.
Step S102: control chip judges whether pressure switch is damaged.Preferably; This air-conditioning can have pressure sensor, the pressure on this pressure sensor and the pressure switch sensing same position, if this pressure sensor the pressure that sensed less than the high-pressure threshold value; That is to say; This locational pressure originally is not enough to this pressure switch is turn-offed, and this is explanation just, and this pressure switch is damaged.
Step S104:, then rerun air-conditioning if control chip is judged the pressure switch damage in step S102.Preferably, damage if judge pressure switch, then air-conditioning system shields the effect (preferably, with the signal shielding that this pressure switch produced) of this pressure switch, and air-conditioning is opened again.
Wherein, above-mentioned air-conditioning can be air-conditioner handset in monomer air-conditioner or the many on-line systems of air-conditioning or the like.Above-mentioned pressure switch can comprise high-pressure switch and low pressure switch.
Through the described air-conditioning of present embodiment compensation startup method, can prevent that the air-conditioning that the damage of pressure switch causes is out of service, thereby increase user's satisfaction, for the sufficient time has been reserved in after-sales service.
Fig. 2 shows the flow chart according to a specific embodiment of the present invention.In Fig. 2:
Step S200: pressure switch is turn-offed.
Step S202: control chip senses pressure switch and turn-offs.
Step S204: control chip makes air-conditioning out of service.In a preferred embodiment, can send shutdown signal by control chip, thereby with the refrigeration module of air-conditioning and/or heat module and close, thereby make air-conditioning stop refrigeration and/or stop to heat.
Step S206: control chip is through pressure sensor senses pressure.Wherein, the pressure on this pressure sensor and this pressure switch sensing same position.In a preferred embodiment, through the scheduled time, control chip is through pressure sensor senses pressure after air-conditioning is closed.That is to say that after a period of time out of service, after promptly the locational pressure at pressure switch place reduced gradually, control chip was through pressure sensor senses pressure at air-conditioning.
Step S208: if pressure less than the high-pressure threshold value, but pressure switch still turn-off, then control chip is judged pressure switch and is damaged.Wherein, this high-pressure threshold value can be arranged in the memory module in the control chip in advance.In the present embodiment, pressure switch is a high-pressure switch.Therefore, in this enforcement, the high-pressure threshold value is represented to keep air-conditioning and is run well and need not the maximum pressure of reporting to the police or stopping.Non-pressure is excessive owing to damaging if the pressure that arrives through above-mentioned pressure sensor senses, is then explained pressure switch less than this high-pressure threshold value just breaks off.
Step S210: if control chip is judged the pressure switch damage in above-mentioned steps, then control chip reruns air-conditioning.
Step S212: if control chip reruns this air-conditioning in above-mentioned steps, then whether pressure sensor is controlled air-conditioning through pressure sensor and is moved.That is to say, damage if judge pressure switch, then can't be again pressure switch through this damage continue to control above-mentioned air-conditioning, therefore, can continue the pressure of air-conditioning is carried out sensing through above-mentioned pressure sensor.When this pressure sensor senses is excessive to pressure, then makes air-conditioning out of service, thereby after with the pressure switch shielding, the protection to this air-conditioning can be provided still through control chip.In one embodiment, if pressure greater than critical pressure, then perhaps makes air-conditioning out of service the air-conditioning frequency reducing.Wherein, critical pressure is the maximum pressure or the minimum pressure that on the position of pressure sensor institute sensing air-conditioning is broken down.
Wherein, above-mentioned air-conditioning can be air-conditioner handset in monomer air-conditioner or the many on-line systems of air-conditioning or the like.
Through the described air-conditioning of present embodiment compensation startup method, can prevent stopping of air-conditioning that the damage of pressure switch causes, thereby increase user's satisfaction, for the sufficient time has been reserved in after-sales service.In addition, through with this air-conditioning of pressure switch shielding adopts pressure sensor continuation afterwards protection that damages, can backup be provided for pressure switch, thereby guarantee the normal operation of air-conditioning.
Except specific embodiment shown in Figure 2, in another specific embodiment, pressure switch can also be low pressure switch but not high-pressure switch.If pressure switch is the low pressure switch, then in step S208, if pressure greater than the low pressure threshold value, but pressure switch still turn-off, then control chip is judged pressure switch and is damaged.Wherein, the low pressure threshold value can be arranged in the memory module in the control chip in advance.The low pressure threshold value is represented to keep air-conditioning and is run well and need not the minimum pressure of reporting to the police or stopping.Non-pressure is too small owing to damaging if the pressure that arrives through above-mentioned pressure sensor senses, is then explained pressure switch greater than this low pressure threshold value just breaks off.Other steps all with the described embodiment of Fig. 2 in corresponding steps identical, therefore repeat no more.
Below will the present invention be described through an instance.
Fig. 3 shows the flow chart according to an instantiation of the present invention.In air-conditioning control program illustrated in fig. 3, the control chip of air-conditioning is constantly through detecting the signal of high-pressure switch, if breaking off appears in this high-pressure switch; Then make this air-conditioning out of service, and detect the signal condition of high-pressure switch always, after remaining off-state in lasting 10 minutes; Judge the sampled value of the pressure sensor in the air-conditioning again, if high-pressure is reduced to below the 30kg, and high-pressure switch still is in off-state; Then show it is that high-pressure switch damages, mask high-pressure switch this moment, and air-conditioning system restarts; But the indicating fault on the computer plate still indication fault exists, and waits for maintenance personal's maintenance.In the process of air-conditioning system operation, the protection continuously effective of above-mentioned pressure sensor when high-pressure is too high, is carried out the frequency reducing protection earlier, if still can not be reduced to setting, then carries out stoppage protection.
