太阳能热水器是怎么样工作的?

太阳能热水器是我们日子中十分常见的节能环保产品,但是很多人对太阳能热水器原理不太清楚,太阳能热水器是怎么作业的呢?太阳能热水器是怎么将能量进行转化的呢?接下来就一同看看太阳能热水器原理吧。
Solar water heater is a very common energy-saving and environmental protection product in our daily life, but many people are not clear about the principle of solar water heater, how does the solar water heater work? How do solar water heaters convert energy? Next, let's look at the principle of solar water heater.
每一个电器作业时,都有它的中心物件。大家都知道的电脑,作业时的中心物件就是CPU,那么你知道太阳能热水器作业时的中心物件吗?那就是真空管。
Every electrical appliance has its central object when it works. Everyone knows that the central object of the operation is the CPU. Do you know the central object of the operation of the solar water heater? That's the vacuum tube.
真空管其实就和一个拉长的暖瓶胆相同,内层和外层之间用真空来隔离。在内层的玻璃胆上面会涂上一层特别的资料,一般都会是黑色的,用来大限度的吸收太阳的辐射。以上就是太阳能热水器作业原理的中心之一!
The vacuum tube is essentially the same as an elongated thermos bottle, with a vacuum separating the inner and outer layers. The inner glass gallbladder will be coated with a special layer of information, usually black, to maximize the absorption of solar radiation. Above is one of the central principles of solar water heater operation!
太阳能热水器作业原理的中心之二,下面让小编为你讲解。阳光照射在真空管的内层上,光子会撞击在真空管的特别涂层上面。这样太阳能就能很好的转化成热能。
The second central part of the operation principle of solar water heater, let's give you a brief explanation. When sunlight shines on the inner layer of the vacuum tube, photons collide with the special coating of the vacuum tube. In this way, solar energy can be well converted into heat energy.
而水箱里边的水,会从特别涂层里边吸取热量。加热之后的水因为密度变小,就会上升,而没有加热的水就会下降。这样整个水箱里边的水都会被渐渐加热的。

The water in the tank absorbs heat from the inside of the special coating. When heated, the water will rise as the density decreases, while the water without heating will decrease. In this way, the water in the whole tank will be gradually heated.

其实太阳能热水器的原理主要包含了以下2个原理:
In fact, the principle of solar water heater mainly includes the following two principles:
(1)水循环原理,就是水会主动流动,这是利用冷水比热水密度大,冷水下沉,热水上升,构成自然对流循环、使水箱中的水逐步变热,达到设定的水温为止。
(1) The principle of water circulation is that water will flow actively. This is to make use of the fact that cold water has a higher density than hot water, sinks in cold water and rises in hot water to form a natural convection cycle and gradually heat the water in the tank until the set water temperature is reached.
当太阳强度不足以满足循环需求的时候,可以在水循环闭路加一水泵,实现强制循环。
When the solar intensity is insufficient to meet the cycle demand, a water pump can be added to the closed circuit of the water cycle to realize the forced cycle.
(2)集热器吸热原理: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,这样就有效的保留了太阳能的热量。再通过这种热量将冷水逐步加热为热水。
(2) Heat absorption principle of collector: There is a special coating on the collector surface of solar water heater. This coating has a great absorptivity to the solar visible light scale. In the future, the 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 too much solar visible light. The heat of Yang energy. Through this heat, the cold water is gradually heated to hot water.
