Description
Technical field
The present invention relates to the method and system that field of heating ventilation air conditioning more particularly to a kind of building heat preservation performance recognize.
Background technology
Building energy consumption is primarily referred to as the energy consumption during building use, including constructure heating, air-conditioning, hot water are supplied, cook a meal
Thing, illumination and architectural electricity energy consumption.With the raising of living standards of the people and the adjustment of the industrial structure, building energy consumption proportion can be into
One step improves.During China is in urbanization high speed development at present, for adapt to urban population rapidly increased demand and
Continue horizontal needs of improving the people's livelihood, the total amount of annual cities and towns new building will be continuously maintained in 10 in the preceding China of the year two thousand twenty
Hundred million m2Left and right, it will be 100~15,000,000,000 m to increase cities and towns civil buildings area newly to the year two thousand twenty2.Since living standards of the people improve, adopt
Warm demand line constantly south is moved, and will have 7,000,000,000 m in new building2Heating, 1,000,000,000 m are needed above2Left and right is heavy construction.According to mesh
Preceding building energy consumption is horizontal, then needs to increase by 1.4 hundred million tons of mark coal/years for heating, increase by 4000~450,000,000,000 kwh/a electricity consumptions.
This will generate immense pressure to China's energy supply.
Different regions, it is different types of building not only had differences on total energy consumption, energy consumption component characteristic there is also
Bigger difference.For overwhelming majority building, the proportion shared by heating air conditioning is all very big.In the heating air conditioning energy of building
In consumption, most of is directly or indirectly caused by building enclosure again.By taking northern heating districts residential housing as an example,
In the heating energy consumption for accounting for total energy consumption 65%, in addition to 1/4 or so energy consumption is caused since heating system adjusts uneven, inefficiency
It is outer, remaining be essentially all by caused by building enclosure (heat consumption of building enclosure includes that building is gone along with sb. to guard him to eliminate
The energy of the injections such as structure different transfer of heat, solar gain, indoor extravasation wind heat exchange).
It is comprehensively strong to new building if country makes a decision to take charge of Building Energy-saving Work severely if from now on according to expert calculation
System implements energy-saving design in construction and application, and carries out energy saving transformation step by step to existed building, arrives the year two thousand twenty, China's building
Energy consumption can reduce by 3.35 hundred million tons of standard coals, and air-conditioning peak load can reduce by about 80,000,000 kilowatt hours and (be equivalent to 4.5 pipe of reinforced concrete at Three Gorges Power Station
Output at full capacity, reduce power construction invest about 600,000,000,000 yuan), energy shortage situation and pollution pressure will greatly alleviate.
But if continuing to let drift, this current section opportunity good greatly is missed, firm effective measures is not taken, then will aggravate significantly for a long time
National energy is born, and is generated serious restriction to the sustainable development of China's economic society, is caused to energy security and atmospheric environment
Significant threat.
An important ring for building energy conservation is the heat preservation of building enclosure, and there is specific regulation in country in this regard, designs rank
Section is also designed and has been required to this, but the synthesis that building is made of multiple systems, there is wall, window, door etc..It applies
Work means and the horizontal heat preservation to building and energy saving important.Same material, different construction technologies, heat preservation
Effect has apparent difference.Therefore, although《Civil Building Energy Conservation design standard》(JGJ-26-95) ensures in the design phase
The thermal property of buildings exterior-protected structure reaches target call, but does not ensure that and after building construction is complete can also reach energy saving
It is required that because the construction quality of building is equally very crucial.Judge whether buildings exterior-protected structure thermal property reaches standard
It is required that only lean on the test data (i.e. wall, door and window etc.) of part that can not provide conclusion, moreover the use material of wall, door and window,
Thickness and manufacturing process etc. can all have an impact practical heat preservation level, and the synthesis thermal property of building needs on-the-spot test.
In building thermal performance design, heat-insulating property is typically used for heat transfer coefficient k and indicates.Domestic existing heat transfer across wall system
The method of number Site Detection mainly has：(1), heat-flow meter is sent out；This method passes through component using heat-flow meter and temperature sensor measurement
Heat flow value and surface temperature, by the way that its thermal resistance and heat transfer coefficient is calculated.It detects basic principle：In tested position cloth
Heat-flow meter is set, the surfaces externally and internally around heat-flow meter arranges thermocouple, and each section tested is connected by conducting wire, will
Test signal directly inputs microcomputer, by computer digital animation, can find out heat flow value.(2), Heat-box method；Heat-box method is to be based on
The principle of one-dimensional steady-state heat transfer establishes required temperature, wind speed and spoke respectively in the babinet (hot tank and ice chest) of test specimen both sides
Condition is penetrated, after reaching stable state, the surface temperature of air themperature, test specimen and cabinet wall is measured and is input to the work(of batch meter
Rate, so that it may to calculate the thermal transport property of test specimen --- heat transfer coefficient.(3), infrared hot line instrument method.
However in practical building heat preservation performance test, heat-flow meter method and Heat-box method all only measure single building enclosure
The heat transfer coefficient of (such as wall, door, glass pane) is unable to measure out thermal technology's property of the building enclosure entirety after constructing, installing
Can, as door adds the loss that energy band is carried out in the gap including door itself after frame；Wall adds the heat transfer feelings stitched together with wall after heat bridge
Condition, the complex heat transfer situation etc. of the glass and window frame of window, gap etc..Although thermal infrared imager can rapidly and accurately measure object
The temperature in body surface face, but by it can measure be only surface of wall temperature, heat flow value can not be measured, thus infrared
Thermal imaging system can not be used alone to the heat transfer coefficient of detection wall, for comparing reference when analyzing testing result, therefore can only
Qualitative analysis is without energetic index.The complex heat transfer situation of all building enclosures is merely that cannot calculate by above-mentioned calculating
Come, so the integral heat insulation situation for representing architectural exterior-protecting construction that can not be accurate, quantitative.
