太阳能热水器的工作原理是什么你知道吗?

1、太阳能热水器集热器吸热原理
1. Thermal Absorption Principle of Solar Water Heater Collector
太阳能热水器的集热器外表有一特别的涂层,此涂层对太阳能可见光规模具有很大的吸收率,吸收为热今后,集热器的散热热辐射波长在长波规模,该涂层对长波的发射率很低,这样就有效的“滞留”了太阳能的热量。
There is a special coating on the collector surface of solar water heater. This coating has a great absorption rate to the solar visible light scale. In the future, the heat radiation wavelength of the collector will be in the long wave scale. This coating has a very low emissivity to the long wave, so it can effectively "retain" the solar energy heat.
2、太阳能热水器循环原理
2. Circulation Principle of Solar Water Heater
运用冷水比热水密度大,冷水下沉,热水上升,形成天然对流循环、使水箱中的水逐步变热,达到顾客满足的水温停止。当太阳强度不足以满足循环需要的时分,能够在水循环闭路加一水泵,完成强制循环。
The use of cold water is more dense than hot water, the cold water sinks, the hot water rises, forming a natural convection cycle, so that the water in the tank gradually becomes hot, to achieve customer satisfaction of the water temperature stop. When the solar intensity is not enough to meet the needs of the cycle, a pump can be added to the closed circuit of the water cycle to complete the forced cycle.
3、太阳能热水器保温原理
3. Thermal Insulation Principle of Solar Water Heater
太阳能保温水箱和其它保温水箱相同,是储存热水的容器。由于太阳能热水器只能白日作业,而人们一般在晚上才运用热水,为了使白日出产的热水在到晚上或隔天运用时坚持必定的温度,所以有必要通过保温水箱把热水储存起来。
Solar thermal insulation water tank is the same as other thermal insulation water tank, which is a container for storing hot water. Because solar water heaters can only work in the daytime, and people usually use hot water in the evening, in order to make the hot water produced in the daytime stick to a certain temperature when it is used in the evening or the next day, it is necessary to store hot water through an insulating water tank.
保温水箱有三部分组成:外胆、聚氨酯发泡层和不锈钢内胆,其间,聚氨酯发泡层担任太阳能热水器的保温,聚氨酯的保温功能杰出,是目前国内一切建材中导热系数更低(≤0.024),热阻值更高的保温材料。
Thermal insulation water tank consists of three parts: outer gallbladder, polyurethane foam layer and stainless steel inner gallbladder. In the meantime, polyurethane foam layer acts as the thermal insulation of solar water heater. Polyurethane has outstanding thermal insulation function. It is the lowest thermal conductivity (<0.024) and the highest thermal resistance of all building materials in China.
太阳能热水器的发泡层厚度一般在50mm-70mm之间,实践保温功能则取决于出产厂家的发泡机械、标准化模具和工艺技术水平。

The thickness of foaming layer of solar water heater is generally between 50mm and 70mm. The practical insulation function depends on the foaming machinery, standardized mould and technological level of the manufacturer.

4、真空管太阳能热水器作业原理

4. Working Principle of Vacuum Tube Solar Water Heater
太阳能热水器是由全玻璃真空集热管、保温水箱、支架三大部件组成。其中心集热元件是全玻璃真空集热管,它由两根为同心圆的高硼硅特硬玻璃管组成,内层玻璃外壁采用磁控溅射真空镀膜工艺镀膜,该涂层对太阳光有选择性吸收,其吸收比≥0.92,发射比≤0.09(80℃),具有高吸收率和低发射率。
Solar water heater is composed of three parts: all glass vacuum heat collector, heat preservation water tank and bracket. The central collector is an all-glass vacuum collector, which consists of two concentric high borosilicate hard glass tubes. The outer wall of the inner glass is coated by magnetron sputtering vacuum coating process. The coating has selective absorption of sunlight, and its absorption ratio is more than 0.92, emission ratio is less than 0.09 (80 C), with high absorption and low emissivity.
真空集热管将吸收的太阳辐射转换成热能,运用冷水比热水密度大,冷水下沉,热水上升的特点,在真空管内形成冷水自上而下,热水自下而上的天然循环,使整个水箱中的水温逐步升高,达到必定温度。
Vacuum collector tube converts solar radiation absorbed into heat energy. By using the characteristics of high density of cold water, sinking of cold water and rising of hot water, a natural cycle of cold water from top to bottom and hot water from bottom to top is formed in vacuum tube, which gradually increases the water temperature in the whole tank and reaches a certain temperature.
热水工程系统更常见的莫过于太阳能了,工厂家庭高楼处处都是,我国这么多年来广泛运用好了太阳能热水器作业原理,真空管、平板式太阳能热水器,平板式的愈加让顾客喜欢,节能作用也是很好,价格上可能会更贵一点但长期以来它是更棒的一款。
The most common hot water engineering system is solar energy, factory and family buildings are everywhere. Over the years, our country has widely used the principle of solar water heater, vacuum tube, flat solar water heater, flat solar water heater, more and more customers like it, energy-saving effect is very good, the price may be more expensive, but for a long time it is the best one.
