Description

technical field [0001] The invention relates to the technical field of barns, in particular to a barn device which uses a multilayer reflective film to reduce radiation heat leakage. Background technique [0002] Radiation heat transfer: black body radiation has two forms of surface radiation and cavity radiation, and the essence of these two forms of black body radiation is the same. The laws describing black body radiation mainly include Planck's law, Wien's displacement law and Stephen Boltzmann's law. The full-wavelength radiation power of the black body surface is: E b =σT 4 [0003] This is the Stefan-Boltzmann law; a cavity whose inner surface is at a uniform temperature behaves closest to a black body. If a small hole is opened in the cavity, according to the principle of thermodynamics, it can be proved that the radiation leaving the small hole only depends on the surface temperature and is equivalent to the emission of the black body surface. The radiation ener...

Problems solved by technology

[0004] According to the theory of black body radiation mentioned above, the temperature of the existing barn is 10-60°C higher than the ambient temperature. Therefore, through the calculation of radiation heat transfer, the heat leakage can be calculated, and this amount is an order of magnitude larger than the heat leakage calculated by the heat conduction of the insulation material. Therefore, For the barn, radiation heat leakage, especially at night when the ambient temperature is low, is the main contributor to the heat leakage of the barn , in order to reduce the leakage, the heat leakage of the barn through thermal radiation is much larger than the heat leakage through heat conduction, there is an order of magnitude difference

[0005] The existing technology starts from the wall insulation material, and by changing the brick wall into polystyrene board, rock wool composite board, and then polyurethane composite board, from the perspective of thermal conductivity, the heat leakage is still reduced, and the load of the barn is reduced. A certain amount of energy saving and consumption reduction has been achieved, but this reduction is less than 20W per square meter, and the reduction of heat leakage is not enough to achieve better energy saving and consumption reduction
