太阳能储水箱的密闭性及支架的牢固性

1、储水箱的密闭性及支架的牢固性。太阳能热水器水箱内胆均采用不锈钢材料,仔细观察一下,焊接口是否与母材料基本相同;其次是支架是否牢固。相对来说,铝合金型材比镀锌板型材的支架更稳固、更耐腐蚀、更耐用。

1 、 the tightness of the water storage tank and the firmness of the support. The water tank of the solar water heater is made of stainless steel, and carefully observed whether the welding interface is basically the same as that of the mother material. The second is whether the bracket is firm. Comparatively, the aluminum alloy profile is more stable, more corrosion resistant and more durable than the galvanized plate profile.

2、集热管的性能。优质的真空集热管的表面应该是光洁无瑕,镀膜为纯黑色或蓝色;看一下,反射板选材及结构安装是否合理,这样能耐腐蚀性会较强,好的反射板外表具有持久的光泽和陶瓷感,像力诺瑞特德国原装进口的CPC反光板,表面经过了PARADIGMA公司独有的陶瓷镜面处理,并且曲面符合科学的复合抛物线,聚光率也会大大提高。

2, the performance of heat collecting tube. The surface quality of the vacuum tube should be flawless, coating is pure black or blue; look at the reflector material and installation structure is reasonable, so the corrosion resistance will be stronger, reflecting plate appearance good shiny and durable ceramic like CPC reflector, linuoruite imported from Germany, through the surface of the PARADIGMA's unique ceramic mirror processing, and surface with composite parabolic science, concentrating rate will be greatly improved.

3、使用中的方便程度。一台高品质的太阳能热水器,应备有加热的辅助装置、水温水位仪等选配件装置的接口。

3, the convenience of use. A high quality solar water heater shall be provided with a heating auxiliary device, an interface for water temperature, water level meter and other fittings.

目前不少人有一种误解,认为水箱的温度越高就说明热性能越好。实际上水温高低不能说明产品的好坏。

At present, many people have a misunderstanding, think tank that higher temperature thermal performance is better. In fact, the water temperature does not tell the quality of the product.

更科学的办法是讲就热效率和热损系数。因为温度不是越高就越好,因为真空管的配比大了温度自然就高了,而到底什么温度合适是建立在一个恰当的平衡点上,真空管配比太大在夏季太阳能持续沸腾状态,水箱内容易结垢,极大的降低了水箱的使用寿命。

The most scientific way is to tell about thermal efficiency and heat loss coefficient. Because the temperature is not the higher the better, because the ratio of high temperature vacuum tubes are naturally high, but in the end what the proper temperature is based on an appropriate balance point, vacuum tube ratio is too high in the summer solar continuous boiling state, the water tank is easy to scale, greatly reduces the service life of the water tank.

4、储水箱保温性能。水箱、外壳端盖是否形成一个整体,无缝隙,这样防腐蚀性强,寿命也会较长。劣质保温层保温材料以次充好,采用普通聚氨酯,更有甚者采用塑料泡沫,几个月后保温效果直线下降,一年后基本不保温。

4 、 heat preservation performance of water storage tank. Whether the water tank, the shell and the end cover form a whole without gaps, so that the corrosion resistance is strong and the service life is longer. Inferior insulation insulation materials used in ordinary Pu, shoddy, even using plastic foam, a few months after the insulation effect of straight down, one year after the basic insulation.
