購買太陽能熱水器時，有哪些技術指標可供參考？
2023-09-12
我們在購買太陽能熱水器的時候，可以參考一些技術指標來判斷產(chǎn)品質量和適用范圍，下面太陽能配件廠家就給我們總結了一些購買太陽能熱水器時可供我們參考的技術指標，希望對大家有所幫助！
When we buy solar water heaters, we can refer to some technical indicators to judge the product quality and scope of application. The following manufacturers of solar energy accessories summarize some technical indicators for us to refer to when buying solar water heaters, hoping to be helpful to you all.
1.注意真空管之間的管間距，一般兩管的中心距在80mm左右為宜。
1. Attention should be paid to the tube spacing between the vacuum tubes. Generally, the center distance between the two tubes is about 80 mm.
2.注意產(chǎn)品的設計是否能充分利用到真空管的吸熱面，真空管能否大程度上受光。
2. Pay attention to whether the product design can make full use of the heat absorbing surface of the vacuum tube and whether the vacuum tube can be illuminated to the greatest extent.
3.細觀察真空管內玻璃管上的涂層，這層涂層叫太陽能選擇性吸收涂層，質量好的涂層顏色均勻，膜層無劃痕、無起皮或脫落現(xiàn)象，玻璃上也沒有結石或節(jié)瘤現(xiàn)象，支撐內玻璃管的支撐件放置端正、不松動。
3. Look carefully at the coating on the glass tube in the vacuum tube. This coating is called the solar selective absorption coating. The coating with good quality is uniform in color. There are no scratches, peeling or shedding on the film. There are no stones or nodules on the glass. The supporting parts of the inner glass tube are positioned correctly and not loosened.
4.熱性能指標中，“平均日效率”越高越好，“平均熱損系數(shù)”越低越好。
4. Among the thermal performance indicators, the higher the average daily efficiency, the better the average thermal loss coefficient.
5.檢查水箱保溫層厚度。平板保溫層厚度應≥50mm，以聚胺脂整體發(fā)泡保溫好。聚胺脂發(fā)泡呈淡黃色，有點象海棉，發(fā)泡體有較均勻的細孔，用手擠壓有一定的彈性，但保溫層太軟則說明其密度較小，不利于保溫。
5. Check the thickness of insulation layer of water tank. The thickness of the insulation layer should be more than 50 mm, and the polyurethane foaming insulation is the best. Polyurethane foam is light yellow, a little like sponge, foam body has more uniform fine holes, hand extrusion has a certain degree of elasticity, but the insulation layer is too soft, indicating that its density is small, not conducive to heat preservation.
6.一般來說在冬天和無陽光的天氣，需要配合電加熱裝置來使用，因此還應該選擇具有電氣設計的產(chǎn)品。
6. Generally speaking, in winter and sunless weather, it is necessary to cooperate with electric heating device to use, so we should also choose products with electrical safety design.
7.家用太陽能熱水器的支架設計應合理，應有足夠的強度和剛度才能確保有足夠的承重能力。這一點尤其重要，很多不合格廠家的太陽能熱水器由于在抗風性設計和產(chǎn)品質量上存在一些問題，容易造成吹落、塌架、真空管破碎等較為嚴重的損失。
7. The bracket design of domestic solar water heater should be reasonable, and enough strength and stiffness should be required to ensure adequate load-bearing capacity. This is particularly important. Many unqualified solar water heaters have some problems in wind resistance design and product quality, which can easily cause serious losses such as blow-down, collapse, vacuum tube breakage and so on.
