Solar greenhouse is featured with low heat transfer coefficient, good heat preservation, moderate weight, rolling up and down easily, firmness, good wind resistance, long service life, good waterproofness, long and endurable heat preservation,etc. So how to choose insulation blanket for solar greenhouse?
After the type of the materials of insulation blanket for solar greenhouse is selected, its insulation performance will mainly depend on the thickness of the insulation blanket, more explicitly, the thickness of insulation core.In principle, the thickness of the thermal insulation material on the front slope of solar greenhouse must be matched with the thermal insulation performance at the back wall and back roof of the greenhouse. In this way, the heat dissipation of the greenhouse in all directions can be the same, and the indoor temperature can be even. However, because the insulation material at the front slope is limited by the coefficient of material thermal conductivity, usually the thermal resistance of the insulation material at the front slope is far less than the one at the wall, so as to that the heat dissipation of the greenhouse at night through the front slope still accounts the most part of the total heat dissipation of the greenhouse.In order to reduce the temperature difference in the greenhouse as much as possible, it is required that the thermal resistance of the thermal insulation material covering the front slope of the greenhouse at night should reach more than 2/3 of the total thermal resistance of the wall.
