Technical field
The present invention relates to the air conditioner field, exactly refer to a kind of sniffer of natural hydrocarbon working medium cold-producing medium.
Background technology
At present, the cold-producing medium that air conditioner generally uses such as R22, has stronger destruction to ozonosphere, and discharges greenhouse gases, and is huge to Gloal Climate Change Impact.And natural carbon-hydrogen refrigerant has ozonosphere is not destroyed, and does not discharge the huge advantage of greenhouse gases, so the air-conditioning of the natural hydrocarbon working medium cold-producing medium of application, has very strong realistic meaning and huge economic interests.
Because natural hydrocarbon working medium cold-producing medium such as R290, has inflammable and explosive character, therefore in air conditioner industry, how to realize low-cost detection to natural hydrocarbon working medium leakage of refrigerant, seem safely particularly important with the use that ensures air-conditioning.
Summary of the invention
For defects, the technical matters that the present invention solves is to provide a kind of sniffer of natural hydrocarbon working medium cold-producing medium, can effectively survey the leakage of using natural hydrocarbon working medium cold-producing medium, thereby guarantees that air-conditioning uses safety.
In order to solve above technical matters, the sniffer of natural hydrocarbon working medium cold-producing medium provided by the invention, comprise gas collecting pipe, reducer pipe, concentration detecting module and extraction fan, described gas collecting pipe is connected with described reducer pipe, and described concentration detecting module is arranged between described reducer pipe and the described extraction fan.
Preferably, the quantity of described gas collecting pipe is more than two, and described gas collecting pipe is connected with described reducer pipe by mixing tube.
Preferably, also comprise filtering layer, described filtering layer is arranged on the porch of described reducer pipe.
Preferably, described concentration detecting module is arranged between described reducer pipe and the described extraction fan by draw-in groove, described draw-in groove respectively with described reducer pipe be connected extraction fan and be connected.
Preferably, described concentration detecting module is connected with air-conditioner controller.
Preferably, the described sniffer left and right sides is provided with fixed orifice, and described sniffer is fixed by described fixed orifice.
The sniffer of natural hydrocarbon working medium cold-producing medium provided by the invention, comprise gas collecting pipe, reducer pipe, concentration detecting module and extraction fan, described gas collecting pipe is connected with described reducer pipe, and described concentration detecting module is arranged between described reducer pipe and the described extraction fan.Compared with prior art, the sniffer of natural hydrocarbon working medium cold-producing medium provided by the invention, the gas collecting pipe is arranged in the position that needs to gather gas, start extraction fan, the gas that gathers enters reducer pipe by the gas collecting pipe, the concentration of flowing through acquisition module gathers its concentration value, and analysis of data collected fed back to controller, gas after the detection finally flows out detector through extraction fan, finish detection of gas, therefore can effectively survey the leakage of using natural hydrocarbon working medium cold-producing medium, thereby guarantee that air-conditioning uses safety.
Description of drawings
Fig. 1 is the structural representation of the sniffer of natural hydrocarbon working medium cold-producing medium in the embodiment of the invention, and the direction of arrow is the direction of motion of natural hydrocarbon working medium cold-producing medium among the figure.
Embodiment
For those skilled in the art can understand technical scheme provided by the present invention better, set forth below in conjunction with specific embodiment.
See also Fig. 1, this figure is the structural representation of the sniffer of natural hydrocarbon working medium cold-producing medium in the embodiment of the invention, and the direction of arrow is the direction of motion of natural hydrocarbon working medium cold-producing medium among the figure.
The sniffer of the natural hydrocarbon working medium cold-producing medium that the embodiment of the invention provides, comprise gas collecting pipe 1, reducer pipe 4, concentration detecting module 5 and extraction fan 6, gas collecting pipe 1 is connected with reducer pipe 4, and concentration detecting module 5 is arranged between reducer pipe 4 and the extraction fan 6.
Extraction fan 6 provides power to the motion of the probe gas in the detector, so that probe gas flows through concentration detecting module 5 with certain flow velocity, guarantees to survey and can normally effectively carry out.
The quantity of gas collecting pipe 1 is three, is arranged in the position that needs to gather gas, and three gas collecting pipes 1 are connected with reducer pipe 4 by mixing tube 2, and mixing tube 2 gathers the gas that gathers.
The porch of reducer pipe 4 is provided with filtering layer 3, and filtering layer 3 will gather gas filtration, and the gas flow that will the gather flow direction is stable, and the gas of avoiding gathering forms endless loop, affects Effect on Detecting.
Reducer pipe 4 is crossed the long-pending size of change pipeline section, adjusts the flow velocity that gathers gas, and further stabilizing gas flows to and fluidised form, forms simultaneously optimum flow rate and fluidised form that concentration detecting module 5 needs as far as possible, improves detection accuracy and accuracy.
Concentration detecting module 5 is arranged between reducer pipe 4 and the extraction fan 6 by draw-in groove 7, and draw-in groove 7 is connected with extraction fan with reducer pipe 4 respectively and is connected; Concentration detecting module 5 is connected with air-conditioner controller.The air-flow concentration data of 5 pairs of collections of concentration detecting module gathers and analyzes, and data transmission is controlled the air-conditioning safe operation to controller after will analyzing.
The sniffer left and right sides is provided with fixed orifice 8, and sniffer is fixing by fixed orifice 8.
The workflow of the sniffer of the natural hydrocarbon working medium cold-producing medium that the embodiment of the invention provides is as follows:
First concentration detecting module 5 is inserted draw-in groove 7 interior fixing, then the fixed orifice 8 of detector by left side and right side is screwed on the inner suitable position of air-conditioning (generally being fixed on the air-conditioning bottom near automatically controlled position), gas collecting pipe 1 is arranged in the position that needs to gather gas, start extraction fan 6, the gas that gathers enters mixing tube 2 by gas collecting pipe 1 respectively and gathers, gas after gathering passes through respectively filtering layer 3 and reducer pipe 4, the concentration of flowing through acquisition module 5, its concentration value is gathered, and analysis of data collected fed back to controller, gas after the detection finally flows out detector through extraction fan 6, finishes detection of gas.
