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,市场上销售的家用太阳能热水器种类繁多,按照太阳能集热器种类来区分,可分为真空管式和平板式;按照结构区分,可分为一体式和分体式;按照制作工艺区分,可分为承压式和非承压式。目前,在市场上销售的家用太阳能热水器常见的大都是非承压真空管式家用太阳能热水器。我们在选购家用太阳能热水器时,应注意以下几点:
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. 热性能指标中,“平均日效率”越高越好,“平均热损系数”越低越好。
1. Among the thermal performance indicators, the higher the average daily efficiency, the better the average thermal loss coefficient.
2. 家用太阳能热水器的关键部件就是全玻璃真空太阳能集热管(简称真空管),真空管质量的好坏直接影响到整个家用太阳能热水器的性能。选购时应仔细观察真空管内玻璃管上的涂层,这层涂层叫太阳能选择性吸收涂层,由于各厂家制作工艺不同,涂层颜色会有所区别,但一般都是黑色、深蓝色或深灰色,质量好的涂层颜色均匀,膜层无划痕、无起皮或脱落现象,玻璃上也没有结石或节瘤现象,支撑内玻璃管的支撑件放置端正、不松动。
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. 选购时还应注意真空管之间的管间距,一般两管的中心距在70mm左右为宜。
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. 家用太阳能热水器的支架设计应合理,应有足够的强度和刚度(补充下:还有耐腐蚀性,别用两年支架倒了)才能确保有足够的承重能力。在一些日常风力较大的地区,尤其是沿海地区,在选购家用太阳能热水器时还应注意该产品在设计上是否有抗风能力。
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. 目前市场上,家用太阳能热水器的反光板形式多种多样,有平面反光板、曲面反光板、压花铝板等等,在选购时应注意产品的反光板设计是否能充分利用到真空管的吸热面,真空管能否大程度上受光。(补充:现在大部分都没有反光板了,商家节约了成本,用户产品提高了抗风能力,不要也罢)
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.
