太阳能热水器温度是越高越好吗?

太阳能热水器现在是我们家居常用的设备,在使用中很方便,有的人觉得太阳能热水器温度越高性能越好,这真的是这样吗?下面来看看济南力诺瑞特太阳能的意见吧。
Solar water heater is now our common household equipment, in use is very convenient, some people think that the higher the temperature of solar water heater, the better, is this really the case? Let's take a look at the views of Jinan Renorette Solar Energy.
太阳能热水器的水温是可以规划的。太阳能热水器是一种将光能转化成热能的设备。对一台热水器来讲,采光面积(集热器面积)是一定的,它的更大集热才能就是一定的了。这时,如果水箱里的水容量不一样,那么必定水量少的水温会高一些。这就是为什么相同支数的太阳能热水器水箱表面也基本相同,而水温有高有低的原因所在。实践上集热器上得到的能量是一样的,只不过有不同的表现形式而已,你得到了温度却丢失了热水产值。
The water temperature of solar water heater can be planned. Solar water heater is a device that converts light energy into heat energy. For a water heater, the lighting area (collector area) is certain, and its maximum heat collection ability is certain. At this time, if the water capacity in the tank is different, the temperature of the water with less water will be higher. This is why the same number of solar water heater tank surface is basically the same, and the water temperature has high or low reasons. In practice, the energy on the collector is the same, but in different forms, you get the temperature but lose the hot water output value.
现在许多厂家打着高温的牌,让顾客认为是热性能好,其实是不对的。但是,较高的产水温度却有致命的负面作用。
Now many manufacturers are playing high temperature brand, so that customers think that thermal performance is good, in fact, it is wrong. However, higher water production temperature has a fatal negative effect.
首要,高温必定产生水垢,对全玻璃真空管来讲,由于管子式和水箱连通的,所以,水垢会大面积沉积在管子的底部和附着在管子壁面上,必定影响真空管的转化功率。这就是为什么许多全玻璃管热水器使用效果衰减很快的原因。等量三年后不能用了,可能你现已找不到人了。

Above all, scales must be produced at high temperature. For all glass vacuum tubes, scales will deposit on the bottom of the tubes and adhere to the wall of the tubes, which will affect the conversion power of the vacuum tubes. This is why many all-glass tube water heaters decay very quickly. It won't work after three years. Maybe you can't find anybody now.

其次,热水器在高温状态下作业,转化功率是很低的。经热工核算,它能得到的总能量反而是低的。解决水温高产生的水垢问题是太阳能行业的世界难题,欧洲国家之所以大多数都选用分体式、二次贿赂,就是有效的避免了这个问题。但考虑到我们国家的消费才能有限,目前仅仅是少数人有才能承受这种形式的太阳能热水器。
Secondly, when the water heater works at high temperature, the conversion power is very low. Thermal calculation shows that the total energy it can get is low. Solving the scaling problem caused by high water temperature is a worldwide problem in the solar energy industry. The reason why most European countries choose split type and second bribery is to effectively avoid this problem. But considering the limited consumption capacity of our country, only a few people can afford this form of solar water heater at present.
