Background technology
Current increasingly high for indoor air quality requirement for people, heating and ventilation seems more and more important in the effect of building field.Some building enterprises begin on indoor environment, to work hard, and stride forward to fields such as constant temperature and humidities gradually.Yet the contradiction of comfortableness and energy consumption consumption becomes increasingly conspicuous, and energy-saving and emission-reduction have become the target and the responsibility of the whole society.As everyone knows, the room impermeability is good, and the target of keeping comfortable indoor environment just reaches more easily, and the low cost of for this reason paying of energy consumption is also lower.Therefore the hot and cold amount loss of effectively avoiding hot and cold wind infiltration to cause is to realize an energy-conservation favourable approach.Room impermeability situation should obtain through the inleakage of measuring the room, and the main inleakage in room concentrates on the door and window place.The method of measuring the blower fan air output is at present mainly measured the pressure reduction of blower fan front and back, adopts computing formula to draw the blower fan air output.Because in the door and window air leakage rate testing, the door and window constant voltage environment that need keep is wider, therefore under less and big pressure; Corresponding inleakage also can be bigger with air output gap under the usual pressure; Will there be bigger error in the process of above-mentioned measurement blower fan air output, especially regulates the blower fan of air quantity through opening and closing the different-diameter nozzle, and the error that when nozzle switches, exists is bigger; Therefore adopt prior art and device to test door and window impermeability result inaccurate; Error is big, poor stability, and the test process noise is big simultaneously.
The utility model content
The utility model discloses a kind of employing tracer gas on-the-spot test door and window impermeability device, drawback such as its purpose is to overcome that existing door and window air tightness test device to test accuracy is low, poor stability and noise are big.The utility model adopts frequency conversion fan to the air-supply of doors and windows sealing place, and when keeping the seals at constant pressure, the constant air output of frequency conversion fan is the inleakage under this pressure of door and window.Because no longer employing adds nozzle and is used for pressure measurement and flow rate calculation, so the test process noise is low, can frequency conversion fan be embedded in the airduct in addition, can also make measuring equipment compact more.
A kind of employing tracer gas on-the-spot test door and window impermeability device comprises sealing frame, plastic foil; The gasometry releasing means, frequency conversion fan, concentration display one; Concentration display two, ondoscope and static pressure display are characterized in: sealing frame is arranged on the body of wall enclosed structure that is connected with door and window peripheral to be measured; Fill cloth between sealing frame and the body of wall enclosed structure; Plastic foil is sticked on the peripheral frame of sealing frame, make doors and windows sealing to be measured, plastic foil is provided with two seal bores; One of them seal bore is connected with the static pressure display through rubber tube, and another seal bore is connected with concentration display one, frequency conversion fan, gasometry releasing means, concentration display two through airduct successively; Described frequency conversion fan is connected with ondoscope; The built-in tracer gas of described gasometry releasing means.
Described tracer gas adopts carbon dioxide or sulfur hexafluoride gas.
Described airduct adopts crooked pipeline; Help making tracer gas and test gas fully to mix.
Described frequency conversion fan is centrifugal fan or axial fan, and frequency conversion fan embeds in the airduct pipeline.
The utility model does not need the plastic foil rubberizing, thereby can avoid body of wall is caused damage because plastic foil sticks on the sealing frame.Test process is simple, and accuracy is high, and stability is strong, and it is compact more that the while blowing device becomes, and the noise that produces in the test process is very little.
