Pressure transducer, the first combustible gas probe and the second combustible gas probe are made whether the detection of coolant leakage.
After R290 coolant occurs leakage, in order to alarm signal is sent to user, Safe liquid storage tank device also includes and control
The alarm device that device processed is connected, when coolant leakage detection means detects R290 coolant leakage, control device control report
Alarm device sends alarm signal.The safety that air-conditioning is used further is improve by the setting of alarm device.
In order to be more accurately controlled to electromagnetic valve, Safe liquid storage tank device also includes being separately positioned on first mouth of pipe
2 and second second pressure sensor at the mouth of pipe 3 and the 3rd pressure transducer, second pressure sensor and the 3rd pressure transducer
It is connected with control device.
When R290 coolant has leakage, and the second pressure sensor that receives when control device and the 3rd pressure transducer
Pressure value it is identical when, control device controls the second electromagnetic valve 6 and closes, and the second pressure for then receiving when control device is sensed
The pressure value of device is that (concrete numerical value of setting value, can obtain, i.e., when in medium circulation pipeline setting value according to test herein
Coolant is completely or nearly completely into second pressure sensor corresponding numerical value during tank body 1) when, control device control first is electric
Magnet valve 5 is closed, and completes the recovery of R290 coolant.
In the present embodiment, a kind of air-conditioning is additionally provided, which includes Safe liquid storage tank device as described above.It is preferred that
, air-conditioning includes off-premises station, and Safe liquid storage tank device is disposed in the outdoor in machine.
In order to be further detailed to above-mentioned Safe liquid storage tank device, present embodiment additionally provides above-mentioned air-conditioning
The specific course of work：
When air-conditioning normally runs, the second electromagnetic valve 6 is opened, and the first electromagnetic valve 5 cuts out.From the R290 coolant that compressor is discharged
Enter from first mouth of pipe 2 of tee T, flow out from the 3rd mouth of pipe 4, subsequently into normally freezing or heating circulation, will not enter
In tank body 1.
After R290 coolant leakages detection arrangement monitors to R290 coolant have leakage, the first electromagnetic valve 5 is first turned on, due to
Tank body 1 is in vacuum state, and R290 coolant will be flowed in tank body 1 under the pressure-driven of medium circulation pipeline rapidly.
Inside the tank body 1 after pressure balance with medium circulation pipeline, i.e. second pressure sensor and the 3rd pressure sensing
When the detected pressure value of device is identical, R290 coolant would not be automatically flowed in tank body 1, now close the second electromagnetic valve 6, compressor
Still operating, there is provided pressure remaining R290 coolant can be pressed in tank body 1.
It is after R290 coolant is completely into tank body 1, i.e., when the detected pressure value of second pressure sensor is setting value, fast
Speed closes the first electromagnetic valve 5, tank body 1 is kept apart with extraneous (medium circulation pipeline), R290 coolant is enclosed in tank body 1,
In the moment for closing the first electromagnetic valve 5, compressor is also out of service.
Above-mentioned air-conditioning is mainly pressed into R290 coolant in the tank body 1 of vacuum using the high pressure in pipe-line system, while
Remaining low-pressure coolant is pressed in tank body 1 by the operating pressure of compressor again.
In sum, present embodiment is by arranging safe liquid storage filling device on air-conditioning, it is ensured that R290 coolant is in leakage
When so that in coolant circulating system, remaining coolant almost all is stored within tank body 1, persistently will not be leaked, indoor remaining
The concentration of R290 coolant will be well below the concentration reached required for burning-point.Also arbitrarily will not be discharged in air simultaneously,
Can so prevent the electrostatic or naked light in the external world from R290 coolant igniting, cause other accidents to occur.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain this reality
With new principle, and the restriction to this utility model protection domain can not be construed to by any way.Based on explanation herein,
Those skilled in the art associates other specific embodiments of the present utility model by need not paying performing creative labour,
These modes are fallen within protection domain of the present utility model.
