如何選購家用太陽能熱水器，？濟(jì)南太陽能配件廠家為您做詳細(xì)的介紹：
How to choose solar water heater for home use? How much is the price? Jinan Solar Parts Factory will give you a detailed introduction:
目前，市場上銷售的家用太陽能熱水器種類繁多，按照太陽能集熱器種類來區(qū)分，可分為真空管式和平板式；按照結(jié)構(gòu)區(qū)分，可分為一體式和分體式；按照制作工藝區(qū)分，可分為承壓式和非承壓式。目前，在市場上銷售的家用太陽能熱水器常見的大都是非承壓真空管式家用太陽能熱水器。我們在選購家用太陽能熱水器時(shí)，應(yīng)注意以下幾點(diǎn)：
At present, there are many kinds of household solar water heaters on the market. According to the types of solar collectors, they can be divided into vacuum tube type and flat plate type. According to the structure, they can be divided into one and two types. According to the manufacturing process, they can be divided into pressure type and non-pressure type. At present, most of the household solar water heaters sold in the market are non-pressurized vacuum tubular household solar water heaters. We should pay attention to the following points when purchasing household solar water heaters:
1. 熱性能指標(biāo)中，“平均日效率”越高越好，“平均熱損系數(shù)”越低越好。
1. Among the thermal performance indicators, the higher the average daily efficiency, the better the average thermal loss coefficient.
2. 家用太陽能熱水器的關(guān)鍵部件就是全玻璃真空太陽能集熱管（簡稱真空管），真空管質(zhì)量的好壞直接影響到整個(gè)家用太陽能熱水器的性能。選購時(shí)應(yīng)仔細(xì)觀察真空管內(nèi)玻璃管上的涂層，這層涂層叫太陽能選擇性吸收涂層，由于各廠家制作工藝不同，涂層顏色會有所區(qū)別，但一般都是黑色、深藍(lán)色或深灰色，質(zhì)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(jié)石或節(jié)瘤現(xiàn)象，支撐內(nèi)玻璃管的支撐件放置端正、不松動。
2. The key component of household solar water heater is all-glass vacuum solar collector tube (referred to as vacuum tube). The quality of vacuum tube directly affects the performance of household solar water heater. When choosing and purchasing, we should carefully observe the coating on the glass tube in the vacuum tube. This coating is called solar selective absorption coating. Because of the different manufacturing process of each manufacturer, the color of the coating will be different, but generally it is black, dark blue or dark gray. The coating with good quality is uniform in color, and there are no scratches, peeling or abscission on the film, and there are no stones or nodules on the glass. The supporting parts of the inner glass tube are positioned correctly and not loosened.
3. 選購時(shí)還應(yīng)注意真空管之間的管間距，一般兩管的中心距在70mm左右為宜。
3. When choosing and purchasing, we should also pay attention to the tube spacing between the vacuum tubes. Generally, the center distance between the two tubes is about 70 mm.
4. 家用太陽能熱水器的支架設(shè)計(jì)應(yīng)合理，應(yīng)有足夠的強(qiáng)度和剛度（補(bǔ)充下：還有耐腐蝕性，別用兩年支架倒了）才能確保有足夠的承重能力。在一些日常風(fēng)力較大的地區(qū)，尤其是沿海地區(qū)，在選購家用太陽能熱水器時(shí)還應(yīng)注意該產(chǎn)品在設(shè)計(jì)上是否有抗風(fēng)能力。
4. Household solar water heater bracket design should be reasonable, should have enough strength and stiffness (supplement: there is corrosion resistance, do not use two years bracket collapsed) to ensure adequate load-bearing capacity. In some areas with large daily wind power, especially in coastal areas, attention should also be paid to whether the product has wind resistance in design when choosing household solar water heaters.
5. 目前市場上，家用太陽能熱水器的反光板形式多種多樣，有平面反光板、曲面反光板、壓花鋁板等等，在選購時(shí)應(yīng)注意產(chǎn)品的反光板設(shè)計(jì)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。（補(bǔ)充：現(xiàn)在大部分都沒有反光板了，商家節(jié)約了成本，用戶產(chǎn)品提高了抗風(fēng)能力，不要也罷）
5. At present, there are many kinds of reflective panels in the market, such as flat reflective panels, curved reflective panels, embossed aluminium panels, etc. When choosing and purchasing products, we should pay attention to whether the reflective panels can make full use of the heat absorbing surface of the vacuum tube and whether the vacuum tube can receive the maximum light. (Plus: Most of them don't have reflective panels now. Businessmen have saved costs, and users'products have improved their wind resistance.
