Description

A kind of atmospheric counter radiation test macro
Technical field
The invention belongs to field of measuring technique, can be used for the measurement of atmospheric counter radiation and effective sky temperature.
Background technique
Due to absorbing radiation energy, atmosphere has certain temperature.Atmosphere relies on the outside radiation energy of temperature of itself, as Atmospheric radiation.A part upwards, is scattered and disappeared in cosmic space, is had in terms of determining earth atmosphere weather very heavy in atmospheric radiation The meaning wanted；The downward long-wave radiation of whole atmosphere, the i.e. back radiation of atmosphere, abbreviation atmospheric counter radiation.Atmospheric counter radiation is not only It is extremely important in building field（Passive cooling, solar thermal collector efficiency, building energy conservation）, also have to many other fields Very important meaning.Such as in meteorological field, the prediction of evapotranspiration, the prediction of Snow-melting speed, The prediction etc. that the prediction of surface temperature and frost occur；In agriculture field, influence etc. of the atmospheric counter radiation to plant growth.
Atmospheric counter radiation can generally pass through Pyrgeometer（pyrgeometer）Or pyrradiometer （pyrradiometer）Direct or indirect measurement is carried out, but these instruments are often very expensive, it is impaired to be easy, and make With correction that in the process must also be regular.Each weather station all not no monitoring data of atmospheric counter radiation both at home and abroad at present, so Field data in relation to atmospheric counter radiation is seldom.
There is scholar thus and obtains real-time atmospheric counter radiation data using the method measured indirectly.Clark and Allen were once Using an open water tank as longwave transmissions device, big circulation of vital energy in the wrong direction spoke is measured by the net radiation between measurement sky and the water surface It penetrates.Since the instrument of measurement net radiation is only only the long wave net radiation between the atmospheric counter radiation of measurement and the water surface at night, And making pyranometer data measured not only in the presence of solar radiation on daytime includes long-wave radiation, further includes shortwave radiation, institute It is only used for the atmospheric counter radiation at measurement night in this way.In addition, in cold district, when the water surface freezes, this method is not yet It is applicable in.Later, Tang Runsheng also tests atmospheric counter radiation using unlimited adopting water tank method.Based on water tank thermal balance, by measuring water tank The evaporation rate and water surface temperature of middle water obtain atmospheric counter radiation data between coming.In this way, obtaining the big of Israel area Circulation of vital energy in the wrong direction radiation data.The limitation of also the same climate condition of this method.Such as：In high temperature and humidity area, evaporation from water surface is several It is zero, the moisture in opposite air is also possible to be agglomerated in water.In addition, since the influence factor of evaporation rate on daytime includes too Sun radiation, they propose atmospheric counter radiation test method just for night without solar radiation at the time of be applicable in.
Summary of the invention
The purpose of the present invention is to solve the above problems, propose a kind of atmospheric counter radiation test macro, the test macro It is not influenced by weather and weather, not only can be used for the measurement of atmospheric counter radiation on daytime, but also can be used for night atmospheric counter radiation Measurement.
Basic ideas of the invention are：Sky in platen surface, surface heat transfer is mainly made of four parts thereon, be respectively on The solar radiation q of Surface absorptionsol, following table face upward surface transmitting heat conduction amount qcond, the heat convection of environment and upper surface qconvAnd the long wave net radiation q of upper surface and skynlwr.According to heat balance principle, as long as obtaining upper surface by technological means Upper surface can be calculated in the quantity of heat convection of the solar radiant heat of absorption, the heat conduction amount of upper surface and upper surface and air With the long wave net radiation of sky, and then atmospheric counter radiation can be calculated.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme：
A kind of atmospheric counter radiation test macro, which is characterized in that the system is made of plate and test device, the test dress It sets and is made of temperature measuring device, wind speed tester and solar radiation tester；The thermally conductive system of the size of plate, construction and material Known to number, solar radiative absorption rate and heat radiation emissivity；Test device can with the upper and lower surfaces temperature of continuous collecting plate, Air themperature, wind speed and total solar radiation data.Atmospheric counter radiation can be calculated according to formula (1)：
In formula,q ADR It is atmospheric counter radiation, W/m2；α is the thermal radiation absorption rate of plate upper surface；εFor the hot spoke of plate upper surface Penetrate emissivity；σ is Boltzmann constant, 5.6697 × 10-8, W/m2·K4；T up It is plate upper surface temperature, K；T down It is plate Underlaying surface temperature, K；λFor the thermal coefficient of plate, W/mK；δFor the thickness of plate, m； PFor plate perimeter, m；SFor plate Surface area, m2；VFor wind speed, m/s；F a It is free-convection factor, when plate upper surface temperature is higher than air themperature, value 1.51, otherwise 0.76；T db It is air themperature,K；αsolIt is the solar radiative absorption rate of plate upper surface；I G It is that the horizontal plane sun is total Radiation intensity, W/m2。
Effective sky temperature can be further obtained according to formula (2)：
In formula,T sky It is effective sky temperature, K.
It is an advantage of the invention that：Atmospheric counter radiation test method based on plate and meteorologic parameter has applied widely Advantage.It is applicable not only to the moment at night, and can be used for daytime, is not also limited by weather condition, it is sunny, cloudy to be applicable in, In addition the also not limitation of climate condition --- high temperature and humidity and cold district can be applied.Maintenance is simple, compensates for existing The disadvantages of atmospheric counter radiation test equipment is expensive, fragile provides new approach for current atmospheric back radiation test.
