现在,市场上出售的家用太阳能热水器品种繁复,依照太阳能集热器品种来区别,可分为真空管式平和板式;依照结构区别,可分为一体式和分体式;依照制造工艺区别,可分为承压式和非承压式。现在,在市场上出售的家用太阳能热水器更常见的大都对错承压真空管式家用太阳能热水器。咱们在选购家用太阳能热水器时,应留意以下几点:
Nowadays, there are many kinds of domestic solar water heaters sold on the market, which can be divided into vacuum tube flat plate type according to the variety of solar collectors; integrated type and split type according to the difference of structure; and pressure type and non-pressure type according to the difference of manufacturing technology. Nowadays, most of the most common solar water heaters sold in the market are vacuum tube solar water heaters with right and wrong pressures. We should pay attention to the following points when choosing and purchasing household solar water heaters:
热性能指标中,“均匀日功率”越高越好,“均匀热损系数”越低越好。
Among the thermal performance indexes, the higher the "uniform daily power", the better the "uniform heat loss coefficient".
家用太阳能热水器的要害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,这层涂层叫太阳能挑选性吸收涂层,因为各厂家制造工艺不同,涂层色彩会有所区别,但一般都是黑色、深蓝色或深灰色,质量好的涂层色彩均匀,膜层无划痕、无起皮或掉落现象,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。
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 different manufacturers have different manufacturing processes, the color of the coating will be different, but generally it is black, dark blue or dark gray. The coating with good quality has uniform color, and the film has no scratches, peeling or falling phenomenon. There are no stones or nodules on the glass. The supporting parts for supporting the inner glass tube are placed correctly and not loosened.
选购时还应留意真空管之间的管距离,一般两管的中心距在70mm左右为宜。
When choosing and purchasing, we should also pay attention to the distance between the vacuum tubes. Generally, the center distance between the two tubes is about 70 mm.
家用太阳能热水器的支架规划应合理,应有足够的强度和刚度才干确保有足够的承重才能。在一些日常风力较大的区域,尤其是沿海区域,在选购家用太阳能热水器时还应留意该产品在规划上是否有抗风才能。

The bracket planning of domestic solar water heaters should be reasonable, with sufficient strength and stiffness to ensure adequate load-bearing capacity. In some areas with large daily wind power, especially in coastal areas, when choosing household solar water heaters, attention should also be paid to whether the product has wind resistance ability in planning.

现在市场上,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,在选购时应留意产品的反光板规划是否能充分利用到真空管的吸热面,真空管能否更大程度上受光。

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 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.

在选购时还应考虑到家中常住人口数量,以确定所购买家用太阳能热水器水容量的大小。一般以每人40升水的规范为宜。
The number of permanent residents should also be taken into account when choosing and purchasing, so as to determine the water capacity of the solar water heater purchased. Usually 40 liters per person is appropriate.
另外,许多产品标称的容水量是通过核算每根真空管的容量和水箱内胆容量相加核算出来的,但其实在热水器出水口以下及真空管内的水是无法放出来运用的,用户真正能运用到的水仅仅是入水口和溢流口之间的水量,所以在选购时应问清楚出售商,他们所标称的容水量指的是悉数的容水量还是实际能运用的容水量,两者相差多少。
In addition, the nominal capacity of many products is calculated by calculating the capacity of each vacuum pipe and the capacity of the tank, but in fact, the water below the outlet of the water heater and in the vacuum pipe can not be released for use. The water users can really use is only the amount between the inlet and the overflow port, so in the case of water heater, the water in the water heater outlet and in the vacuum pipe can not be used. When choosing and purchasing, it should be clear to the sellers whether their nominal water capacity refers to the total water capacity or the actual water capacity that can be used, and how much is the difference between the two.
假如够买的家用太阳能热水器需求装备电加热设备,应挑选具有电气安全规划的产品。
If enough domestic solar water heaters are required to be equipped with electric heating equipment, products with electrical safety planning should be selected.
选购其他相关配件,如自动上水设备、水温水位显现仪、电磁阀等,关于这些设备的挑选应慎重,有些功能看似先进,但组成部件过多,可靠性不高,时间一长就容易出问题,挑选时必定要问清楚运用。
Choose and purchase other relevant accessories, such as automatic water supply equipment, water temperature and water level display instrument, solenoid valve, etc. The selection of these equipment should be careful, some functions seem advanced, but the components are too many, reliability is not high, it is easy to have problems in a long time, and the selection must be clearly asked to use.
