Description
Technical field
It is specifically a kind of airtight for exterior window the utility model relates to a kind of air-tightness test device of external window of building
Property detection test device.
Background technique
The air-tightness of exterior window is a very important factor for influencing energy consumption of air conditioning system in buildings.For energy conservation and improve room
Interior thermal environment, there is an urgent need to improve the air-tightness of exterior window.Therefore, carrying out the detection of external window of building air-tightness field is current building section
Can there is an urgent need to.Building doors and windows engineering should carry out live sampling Detection before final acceptance of construction to the air-tightness of external window of building.
Construction unit randomly selects same manufacturer, homologous series, same specification, the 1 group external window of building representative with lattice form
Test specimen, test specimen quantity are three door frame exterior windows.
Currently used detection method are as follows:
It is evaluated with test object unit seam long air infiltration capacity or unit area the quantity of air infiltration under 10Pa pressure difference.
Scene forms plenum chamber using sealing plate, building enclosure and exterior window, is dried from plenum chamber in test object two by air feed system
Positive differential pressure or Negative Pressure Difference are then formed, measurement hole measurement pressure difference is drawn in plenum chamber, flow measurement is installed on air feed system pipeline
Device measures the quantity of air infiltration.Air stream under rubber belt sealing state and normal operating condition is all used by measuring exterior window respectively
Amount difference obtains the actual seepage quantity of exterior window.Since the leakage of exterior window is smaller, by installing flow measurement on air supply line
It will receive the disturbing influence of blower when examination, the problem of it is weak that there are measuring stabilities, low precision.
Summary of the invention
In view of the above problems, the purpose of the utility model is to provide a kind of test device for external window air tightness detection,
The accuracy for improving flow rate test reduces the error that blower disturbance generates.
The purpose of this utility model is achieved through the following technical solutions:
A kind of test device for external window air tightness detection, it is characterised in that: the device includes being arranged on the inside of exterior window
Air inlet and the setting flowmeter of side outside window outside, sealing film is equipped with inside and outside exterior window, and constitute inner seal
The one end in space and outer side seal space, air duct is communicated by air inlet with inner seal space, and the other end and tester connect
It connects；Pressure-measuring pipe is equipped between inner seal space and tester；Flowmeter is communicated by test air hose with outer side seal space.
In the utility model, flowmeter is the flowmeter using wirelessly transmitting data, and the reality of data is carried out with tester
When transmit.Sealing film is plastic film.
The utility model changes original test method, and flowmeter is placed in other the one of the exterior window for being connected to air supply line
Side is sealed exterior window other side using plastic film, and flowmeter is set to the pipe of insertion other side sealing film
The direct infiltration capacity of air that exterior window is measured in road, avoids disturbance when blower air feed, is all sealed by testing exterior window respectively
Difference in flow under state and normal operating condition obtains the quantity of air infiltration of exterior window.Due to test need exterior window two sides simultaneously into
Row, it is contemplated that all in sealing state when wall and exterior window are tested, the route of flowmeter be cannot be connected directly on test equipment,
Therefore the real-time Transmission of data is carried out using the flowmeter and test equipment with wireless data transmission, it is ensured that same pacing when test
Measure the numerical value of pressure and air mass flow.
The utility model, which tests original air mass flow from air inlet measurement, to be changed to the exterior window side opposite with air inlet,
The air mass flow by external window leakage is directly measured, the accuracy of flow rate test is improved, reduces the mistake that blower disturbance generates
Difference.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
A kind of test device for external window air tightness detection, is shown in Fig. 1, the device include be arranged in the inside of exterior window 1 into
Air port 2 and the flowmeter 3 that 1 outside of exterior window is arranged in, are equipped with sealing film 4, sealing film is plastics inside and outside exterior window
Film.The sealing film of two sides respectively constitutes inner seal space 11 and outer side seal space 12 in exterior window two sides.Air duct 5
One end is communicated by air inlet with inner seal space, and the other end is connect with tester 6.Inner seal space and tester it
Between be equipped with pressure-measuring pipe 7.Flowmeter is communicated by test air hose 8 with outer side seal space.Flowmeter is using wirelessly transmitting data
Flowmeter, and with tester carry out data real-time Transmission.
Flowmeter is placed in the other side for being connected to the exterior window of air supply line, using plastic film to exterior window other side
It is sealed, flowmeter is set to the direct infiltration capacity of air for measuring exterior window in the pipeline of insertion other side sealing film,
Disturbance when blower air feed is avoided, is obtained by the difference in flow tested under exterior window whole sealing state and normal operating condition respectively
To the quantity of air infiltration of exterior window.Since test needs to carry out simultaneously on exterior window two sides, it is contemplated that wall and exterior window are all located when testing
It cannot be connected directly on test equipment in the route of sealing state, flowmeter, therefore use the stream with wireless data transmission
Meter and test equipment carry out the real-time Transmission of data, it is ensured that the numerical value of synchro measure pressure and air mass flow when test improves
The accuracy of flow rate test reduces the error that blower disturbance generates.
