Description

A kind of external window of building energy-efficient performance detection device and its control method

Technical field

The present invention relates to a kind of exterior window detection field, specifically a kind of external window of building energy-efficient performance detection device.

Background technique

External window of building is the part that thermal property is most weak in building external envelope structure, is the key link of building energy consumption And key position, show that exterior window energy consumption accounts for about the 30%~40% of building energy consumption according to domestic and international experts and scholars' result of study, has caused Various common concerns.Country " public building energy design standard " GB 50189-2015 and related Residential Buildings Energy are set The energy-saving indexs such as the heat transfer coefficient of external window of building, shading coefficient, solar heat gain coefficient are provided in meter standard, it is existing Most exterior window enterprise mostly uses venetian shutters or Low-e windowpane so that exterior window meets related energy-saving design in construction requirement.

Regional in south China, the main energy-efficient performance index of external window of building is shading coefficient and solar heat gain coefficient, is built It builds and is discussed in detail in professional standard " building doors and windows shading performance detection method " JG/T440-2014 outside using artificial light source detection The detection device and detection method of window shading coefficient or solar heat gain coefficient, which is all based on steady state heat transfer principle, using mark The shading coefficient SC or solar heat gain coefficient SHGC for determining hot tank hair detection external window of building, although above-mentioned detection method can be commented preferably The energy-efficient performance of valence external window of building, but the air themperature stable time is longer in heat death theory case and distribution is more uneven, causes to detect Data accuracy is general, detection time is longer and detection energy consumption is higher.This is because being examined in existing external window of building heat-proof quality It surveys in device, the size of hot heat death theory case larger (long and wide typically no less than 2m × 2m, depth are typically no less than 1m) and heat are handed over Parallel operation is arranged at hot heat death theory box cavity rear portion, and since the exterior window type of detection is more, the inhomogeneity under artificial light source irradiation It is different different with heat exchanger heat absorption speed that the exterior window of type will lead to the distribution of heat death theory the temperature inside the box.For example, for being equipped with building The exterior window of blinds sunshade, simulated light shine through the top that exterior window enters in hot heat death theory case, lead to the top in heat death theory case Air themperature is relatively high, and due to the difference of blinds reflectivity, the temperature deviation value on hot heat death theory box cavity top is also different； For Low-e windowpane or ordinary insulating glass window, simulated light light transmission exterior window can be irradiated on rear side of hot heat death theory case, be caused hot Rear side temperature in batch meter is relatively high, and due to the difference of shading coefficient of external window, and the temperature on rear side of heat death theory box cavity is inclined Difference is also different.

Existing detection device all uses identical detection method for different types of exterior window, i.e., after heat death theory box cavity Heat exchanger is arranged to absorb heat and judge heat by the average air temperature of the temperature sensor acquisition of different location in side The temperature fluctuation amplitude of heat death theory case, this mode are most suitable for Low-e windowpane or the detection of ordinary insulating glass window, It is absorbed into most of heat in hot heat death theory case by heat exchanger rapidly, the air themperature of different location point in heat death theory case Also more uniformly, air temperature fluctuations amplitude can quickly meet testing requirements to cloth；But the exterior window of blinds sunshade is built for being equipped with, Since the heat that simulated light enters hot heat death theory case through exterior window is predominantly located in top, heat exchanger cannot directly absorb heat Amount can only be transmitted by atmospheric heat and absorb the partial heat, and the air themperature of different location is distributed more in heat death theory case Unevenly, air temperature fluctuations amplitude is just able to satisfy testing requirements in a long time, so as to cause the use of detection device on the whole Electric energy consumption is higher, similarly, the exterior window or other kinds of exterior window of hard roller shutter is built for being equipped with, there is also disadvantages mentioned above.
