With reference to shown in Figure 1, embodiments in accordance with the present invention, air-conditioner includes indoor set 20, the throttling being sequentially connected
Device 30, off-premises station 10 and compressor 40, also including above-mentioned combustible refrigerant air-conditioner fire prevention system, combustible refrigerant air-conditioning
Device fire prevention system is disposed in the outdoor on the mounting structure on machine 10 or near off-premises station 10, and the first control valve 60 is arranged on compression
The arrival end of machine 40, the second control valve 80 is arranged to the port of export of throttling arrangement 30.The first control control valve 80 of valve 60 and second
For example, can automatic control switch stop valve.Off-premises station 10 includes the outer blower fan that condenser 11 and correspondence condenser 11 are arranged
12.When combustible refrigerant in by off-premises station 10 discharges off-premises station 10, combustible refrigerant can be accelerated by outer blower fan 12
Mass rate of emission.
With reference to shown in Figure 3, embodiments in accordance with the present invention, the application process of combustible refrigerant air-conditioner fire prevention system
Including：Step S1：Environmental aspect residing for detection off-premises station 10；Step S2：Environmental aspect according to detecting judges whether to send out
It is raw abnormal, and start protection action when environmental aspect is abnormal, to prevent from fire spreading to indoor from outside.
Step S2 also includes：Step S21：When detecting environmental aspect and being abnormal, the second of the port of export of off-premises station 10 is closed
Control valve 80, to prevent combustible refrigerant on fire from flowing into interior with cold-producing medium, ignite indoor set 20.Step
S22：Compressor 40 is kept to continue to run with the t1 times, so that the combustible refrigerant in pipeline can continue to off-premises station
Gather at 10, carry out the recovery of combustible refrigerant, it is to avoid spread combustible refrigerant to interior.Step S23：Shut down, and close chamber
First control valve 60 of the arrival end of outer machine 10.
Step S2 also includes：Step S24：Compare the environmental state information of the position of off-premises station 10, and determine off-premises station
The extremely minimum position of 10 environmental aspect.Step S25：It is determined that apart from the nearest relief valve of environmental aspect exception minimum position
70, open the relief valve 70 and kept for the t2 times, the combustible refrigerant in off-premises station 10 is discharged into into room from the relief valve 70
External environment.Herein, position discharges combustible refrigerant, can farthest reduce generation in combustible refrigerant discharge process
The probability of burning.Step S26：Close the relief valve 70.Combustible refrigerant in off-premises station 10 is discharged into after outdoor environment,
The flammable agent content retained in off-premises station 10 just can greatly reduce, and can reduce below burning concentration, so as to hinder
The only further burning of off-premises station 10, it is also possible to further avoid combustible refrigerant from spreading to interior by pipeline.
Above-mentioned application process also includes step S3：When detecting environmental aspect and being abnormal, control device sends alarm command；
Control alarm device sends alarm.By above-mentioned steps can find in time off-premises station 10 occur fire accident situation, and and
Shi Tongzhi staff is processed, it is to avoid the catching fire of outside environment by combustible refrigerant air-conditioner spreads to room
Inner side, improves safety when air-conditioner is used.While alarm device sends alarm, step S21 can be simultaneously carried out
To the operation of step S23, such that it is able to process the situation on fire of off-premises station 10 in time, the shape on fire of off-premises station 10 is prevented
Condition further deteriorates.
Carry out the application to this combustible refrigerant air-conditioner fire prevention system so that detection means is as temperature-detecting device as an example below
Method is illustrated.
When temperature sensor detects the surrounding of off-premises station 10 less than for example 100 DEG C of ceiling temperature T, control device
Alarm command is not sent.
When the ambient temperature that temperature sensor detects off-premises station 10 is higher than ceiling temperature T, control device is at once
Start protection action, and send control instruction, control alarm device sends alarm.
Control device while control alarm device sends alarm, positioned at the second of the port of export of off-premises station 10 control by control
Valve processed 80 is closed, and to avoid the combustible refrigerant for burning from spreading to interior by the combustible refrigerant in pipeline, compressor continues
The first control valve 60 of the arrival end positioned at off-premises station 10 is shut down and closed after the operation t1 times, to ensure in air-conditioner hose
Combustible refrigerant can concentrate on as best one can in off-premises station 10.
After completing the aforementioned steps, combustible refrigerant can be concentrated in off-premises station 10, this timed unit according to
The actual temperature situation of the off-premises station surrounding detected by temperature sensor is judging to discharge flammable on off-premises station 10
The position of agent least risk, and determine apart from the nearest relief valve 70 in the position, the relief valve 70 is then opened, by flammable
Agent is directly directly released into outdoor environment, and closed safe valve after the time t 2 via the relief valve 70.
Finally control air-conditioner to disconnect due to power supply side indoors with power supply automatically, power-off there is no concern that what sparking ignited asks
Topic.
After completing aforesaid operations, operator can overhaul in time to air-conditioner.
Temperature sensor can also make Smoke Sensor into, by detecting smog come control system work, or can also
Configure temperature sensor and Smoke Sensor simultaneously on the off-premises station 10 of air-conditioner.
Certainly, it is more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art
For, on the premise of without departing from its general principles, some improvements and modifications can also be made, these improvements and modifications
It is considered as protection scope of the present invention.
