Abstract
The present invention relates to a kind of test methods of window chinky altitude, since outdoor air can penetrate into interior by window gap, there will be a temperature difference between window gap and window, and thermal infrared imager can record the figure of different temperatures, so thermal infrared imager and other ancillary equipments can be passed through, scanning window gap temperature region simultaneously gets off the graphic recording in window gap, and the area of window crack gap is then calculated by a software analysis, is denoted as A；The length L in window gap is come out with tape measure again, the ratio of window gap area A and length L are exactly the height h in window gap, this test method do not have to according in external reference books door and window gap effective area coefficient Ce and related calculation formula calculate window gap size indirectly, required window chinky altitude can be accurately obtained.
Description
Technical field
The present invention relates to a kind of measuring technique, more particularly to a kind of test method of window chinky altitude.
Background technology
Today's society, architectural energy consumption is increasing, and saving energy test rises therewith, and it is exactly wherein one to measure window chinky altitude
Item content.Window chinky altitude is obtained it is difficult to measure in practice, most of door and windows according in external reference books
Window chinky altitude is calculated in gap effective area coefficient Ce and related calculation formula indirectly.China is existing not about window
The reference books that chinky altitude calculates, window processing quality is also multifarious, using the data in external handbook, can bring very big
Error.
Invention content
It is difficult measured problem the present invention be directed to window gap size in Practical Project, it is proposed that a kind of window gap
The test method of height can be such that the window gap height error measured greatly reduces.
The technical scheme is that：A kind of test method of window chinky altitude, specifically comprises the following steps：
1）, measure indoor/outdoor temperature-difference, if the indoor and outdoor air temperature difference is little, be less than 5 degrees Celsius, then close window, artificially change
Become indoor temperature so that the indoor and outdoor air temperature difference is more than 5 degrees Celsius；
2）, the precision of thermal infrared imager is debugged；
3）, thermal infrared imager is fixed on a height adjustable holder, and be placed in testing location, adjust infrared thermal imagery
The distance of instrument and window to be measured makes it be directed at window gap, adjusts holder, so that thermal infrared imager is moved up and down, so that red
Outer thermal imaging system records the figure in window gap, and corresponding Data Analysis Software analysis is used in combination to calculate the area A of window crack gap；
4）, measure with tape measure the length L in window gap, the ratio of the area A and length L in window gap are exactly the height in window gap
Spend h.
The beneficial effects of the present invention are：The test method of window chinky altitude of the present invention does not have to according to external related
Door and window gap effective area coefficient Ce and related calculation formula in handbook calculate window gap size indirectly, can be accurately obtained
Required window chinky altitude.
Description of the drawings
Fig. 1 is thermal infrared imager test schematic diagram of the present invention；
Fig. 2 is the pictorial diagram in window gap of the present invention；
Fig. 3 is window gap method for testing height flow chart of the present invention.
Specific implementation mode
Thermal infrared imager test schematic diagram as shown in Figure 1, thermal infrared imager can record the figure of different temperatures, indoor
There may be larger temperature differences for outer air, it is also possible to this temperature difference very little（Less than 5 degrees Celsius）, then will be artificially
The temperature difference of indoor and outdoor is set to become larger, such as using domestic air conditioning, mobile air conditioner or other heat supplies, cooling equipment, due to outdoor empty
Gas can penetrate into interior by window gap, and the pictorial diagram in window gap as shown in Figure 2,1 is wall, in window gap
As soon as will have a temperature difference between 2 and window 3, so window can be scanned by thermal infrared imager and other ancillary equipments
The graphic recording in window gap is simultaneously got off in aperture temp region, and the area A of window crack gap is then calculated by software analysis；
The length L in window gap is come out with tape measure again, the ratio of window gap area A and length L are exactly the height in window gap
Spend h.
Window gap as shown in Figure 3 method for testing height flow chart, test method comprise the concrete steps that：
1, indoor/outdoor temperature-difference is measured, if the indoor and outdoor air temperature difference is little, is less than 5 degrees Celsius, then closes window, manually change
Indoor temperature so that the indoor and outdoor air temperature difference is more than 5 degrees Celsius；
2, the precision of thermal infrared imager is debugged；
3, thermal infrared imager is fixed on a height adjustable holder, and is placed in testing location, adjust infrared thermal imagery
The distance of instrument and window to be measured makes it be directed at window gap, adjusts holder, so that thermal infrared imager is moved up and down, make infrared
Thermal imaging system records the figure in window gap, and homemade Data Analysis Software analysis is used in combination to obtain the area of windowA。
4 and then the length L in window gap is measured with tape measure, the ratio of the area A and length L in window gap are exactly window
The size h in gap.
