平板分体太阳能的优势点在哪?

现在生活渐渐地好了起来太阳能热水器的品种也越来越多今天小编给咱们介绍下平板式太阳能热水器的长处是什么,期望对咱们有所帮助!
Now life is getting better and better. More and more kinds of solar water heaters are made up today. What are the advantages of flat panel solar water heaters? I hope it will be helpful to us!
一、相比一般热水器的优势
I. Advantages over general water heaters
一般的太阳能热水器是通过真空管直接把吸收的“阳光”转到水,而平板太阳能是用铜管其他的直接把热量转化给水。一般的热功率高点,平板的很多都是分体双回路的要加循环泵的。所以,平板太阳能的水质还有运用和寿命一般都要好些。
Generally, solar water heaters transfer the absorbed "sunlight" directly to water through vacuum tubes, while flat-panel solar energy uses copper tubes to convert heat directly to water. In general, at high heat power points, many flat plates are divided into two loops to add circulating pumps. Therefore, the water quality and service life of flat panel solar energy are generally better.
平板太阳能集热器吸收热能,并将热能传导至集热器中的热交换介质中。跟着导热介质温度的升高,在泵的循环作用下,受热的液体在集热器中加热后,进入储水罐的热交换器之中。
The flat panel solar collector absorbs heat energy and transmits it to the heat exchange medium in the collector. With the increase of the temperature of the heat conducting medium, under the circulation of the pump, the heated liquid is heated in the collector and enters the heat exchanger of the water storage tank.
在此,热能被搬运水中,导热介质逐步冷却。冷却后的液体又被推回至集热器中。冷却后的溶液在集热板中再一次被加热而循环到热交换器之中,将热能传给储水罐中的水。这一进程不断重复直至储水罐中一切的水都被加热。
Thermal energy can be transported into water and the heat conducting medium is gradually cooled. The cooled liquid is pushed back into the collector. The cooled solution is heated again in the collector plate and circulated to the heat exchanger, which transfers heat energy to the water in the water storage tank. This process is repeated until all the water in the tank is heated.

自沿程阻力是平板太阳能循环管路以及集热器管路系统的主要阻力。当介质温升高后,由于运动粘度减小,沿程阻力变小,部分阻力的影响变大。

Self-resistance along the path is the main resistance of flat solar cycle pipeline and collector pipeline system. When the medium temperature rises, the drag along the path decreases and the influence of partial drag increases as the motion viscosity decreases.
在必定范围内,当主管管径不变时,加大支管管径,不只沿程阻力敏捷减小,并且部分阻力也将跟着减小,一般地,支管的水力半径应在10mm以上。
In a certain range, when the main pipe diameter remains unchanged, increasing the branch pipe diameter will not only reduce the resistance along the way agilely, but also reduce part of the resistance. Generally, the hydraulic radius of the branch pipe should be more than 10 mm.
当主管管径达到必定值今后,增加主管管径对减小系统阻力意义不大。平板太阳能热水器顶水式用程,家用太阳能热水器和平板分体太阳能的用水方法分为落水式和顶水式。
When the main pipe diameter reaches a certain value in the future, it is not significant to increase the main pipe diameter to reduce the system resistance. Top water use of flat solar water heater, household solar water heater and split flat solar water use methods are divided into falling water type and top water type.
一般太阳能热水器是落水运用方法不受自来水供水影响,其缺点是运用进程中水温先低后高,把握欠好的话简单形成俄然缺水的尴尬。
Generally solar water heater is not affected by tap water supply. Its shortcoming is that the water temperature is low first and then high in the process of application. If it is not well grasped, it will simply cause the embarrassment of sudden water shortage.
平板分体太阳能是顶水方法则是水温先高后低,简单把握,运用者简单适应,但是要求自来水坚持供水能力,在自来水有确保的情况下,引荐运用顶水方法。
Flat panel split solar energy is the top water method, which is the water temperature first high and then low, simple to grasp, simple to adapt to users, but requires tap water to adhere to the water supply capacity, in the case of tap water is guaranteed, recommended the use of the top water method.
