講解下太陽照射對冷庫的影響
About the sun's influence on cold storage
太陽輻射熱與冷庫的建筑外表面積、太陽輻射的強度等因素有關。冷庫設計時應選擇單位庫容量的冷庫建筑外表面較小的結構。
Sun radiate to heat and cold storage of building surface area, the intensity of solar radiation and other factors. Refrigerator design should choose the unit structure of database is less cold storage building outside surface.
太陽輻射強度隨地區、季節、一天中的時間、天空中的云彩、空氣中的水蒸氣含量等的不同而不同。冷庫壁面吸收的太陽輻射熱是由冷庫的朝向及表面對太陽的吸收率決定的。
The intensity of solar radiation with the region, season, time of day, the clouds in the sky, the different contents of water vapour in the air. Cold storage wall absorption of the surface of the sun radiate to heat up the front and is composed of cold storage on the absorption rate of decision of the sun.
冷庫建筑物的朝向在設計中應綜合考慮。冷庫壁面太陽熱的吸收率主要取決于壁面材料的化學成分、表面光滑狀況、表面顏色等^其中表面顏色是影響太陽吸收率的主要因素。
Cold storage of the front of buildings should be considered in the design. Cold storage wall solar heat absorption depends mainly on the chemical composition of wall materials, the condition of the surface is smooth, the surface color ^ surface color is the main factors affecting the solar absorptivity.
冷庫表面顏色越淺，反射太陽輻射熱的能力越大，對太陽熱的吸收率就越小。
Cold storage surface color the more light, the greater the ability of reflecting solar heat, the solar heat absorption.
冷庫安裝根據以上分析：減少太陽輻射熱的方法是采用白色涂料的冷庫外壁。因為白色的外表面對日照有很高的反射率，會減少太陽輻射的影響;而且白色表面對長波有很高的輻射率，在晴朗的夜晚由于外表面對天空的長波輻射，使建筑物的溫度降低‘降低了冷庫的制冷負荷。

Cold storage installation according to the above analysis: reduce sun radiate to heat up the cold storage method is to use white paint walls. Because the appearance of white in the face of rizhao has high reflectivity, can reduce the influence of solar radiation; And white surface for long wave has a high emissivity, in the face of the sky on a clear night due to appearance of long wave radiation, reduce the temperature of the buildings' reduces the cold storage refrigeration load.
