Specific embodiment
It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, it is not intended to limit the present invention.
The present invention provides a kind of processing method of air-conditioner coolant leakage.
Reference picture 1, Fig. 1 is the schematic flow sheet of the processing method first embodiment of air-conditioner coolant leakage of the present invention;
In the present embodiment, air-conditioner includes refrigerant detector and coolant system, the treatment side of air-conditioner coolant leakage Method includes:
Step S10, obtains the refrigerant concentration outside the coolant system of refrigerant detector detection;
Specifically, the processing method of the air-conditioner coolant leakage that the present embodiment is provided is cold for occurring in air-conditioner operation When matchmaker leaks, processed to prevent from setting off an explosion.Air-conditioner includes refrigerant detector and coolant system, and air-conditioner passes through refrigerant Refrigerant concentration outside detector real-time monitoring coolant system i.e. refrigerant passage.The present invention is by straight using refrigerant detector Connect the refrigerant at detection refrigerant detector position, compared with other detection modes, with more rapidly, it is more accurate the characteristics of, And can more ensure the safety of user.
Wherein, the refrigerant of leakage is more delicately monitored in order to ensure refrigerant detector, can be by the refrigerant detector It is installed at the air outlet of the electric-controlled box of the air-conditioner and/or indoor set.
Specifically, it can be seen from the characteristic according to air-conditioner, wind speed during due to air conditioner refrigerating at the air outlet of indoor set is maximum, So once refrigerant is leaked, the refrigerant concentration at the air outlet of indoor set will be typically higher than other positions.Therefore by refrigerant Detector is installed at the air outlet of indoor set the concentration that can be easy to detect that air-conditioner leaks refrigerant.And electric-controlled box is because have The reason for dividing plate, the refrigerant concentration on electric-controlled box periphery is also higher than other positions.So when being installed on refrigerant detector, can be preferential Choose position at electric-controlled box and air outlet of indoor set two.
Step S20, judges whether the refrigerant concentration reaches the first preset value and less than the second preset value, wherein, first Preset value is less than the second preset value;
Specifically, after the refrigerant concentration in getting refrigerant detector, according to the first preset value and the second preset value, sentence Whether the refrigerant concentration of disconnected leakage reaches the preset value of critical value first that may be set off an explosion, and is reached in the refrigerant concentration for judging leakage To after the first preset value, continuation judges whether refrigerant concentration reaches the preset value of dangerous values second that set off an explosion.Wherein it is possible to manage Solution, the first preset value and the second preset value proposed in the present embodiment can be according to air-conditioners as the parameter of judgment threshold Working environment, nominal parameter and load capacity etc. pre-set.
Step S30, it is disconnected by the first circuit if the refrigerant concentration reaches the first preset value and less than the second preset value Opening apparatus disconnect the power supply of air-conditioner.
Specifically, as shown in fig. 7, wherein, 1 is room circuit input end, and 2 is the circuit breaker in room, and 3 is air-conditioning Device, 4 is electrical appliance A, and 5 is other electrical appliances, and 6 is room.First circuit breaker can be arranged between 2 and 3, for controlling Air-conditioner power supply, has reached the preset value of critical value first that may set off an explosion and has also been not up in the refrigerant concentration for judging leakage During the second preset value of dangerous values that set off an explosion, air-conditioner electricity is disconnected by the first circuit breaker between 2 and 3 Source, prevents because the refrigerant that leakage is lighted in the use of air-conditioner sets off an explosion.
