2023-09-12
太阳能作为一种新兴的可再生能源，被普遍应用于我们的日常生活中。在光热转换中，当前应用范围广、技术成熟、经济性好的是太阳能热水器。下面济南太阳能配件公司就为大家提高一下太阳能热水器的工作原理，希望对大家有所帮助！
As a new renewable energy, solar energy is widely used in our daily life. In the light-heat conversion, the solar water heater is the most widely used, the most mature technology and the best economic. Next, Jinan Solar Accessories Company will improve the working principle of solar water heater for you, hoping to help you!
1.吸热过程
1. Endothermic process
太阳辐射透过真空管的外管，被集热镀膜吸收后沿内管壁传送到管内的水。管内的水吸热后温度升高，比重减小而上升，构成一个向上的动力，构成一个热虹吸系统。随着热水的不时上移并贮存在储水箱上部，同时温度较低的水沿管的另一侧不时补充如此循环往复，终整箱水都升高至一定的温度。而平板式热水器，普通为分体式热水器，介质在集热板内因热虹吸自然循环，将太阳辐射在集热板的热量及时传送到水箱内，水箱内经过热交流（夹套或盘管）将热量传送给冷水。介质也可经过泵循环完成热量传送。
Solar radiation passes through the outer tube of the vacuum tube and is absorbed by the collector coating and then transferred to the water in the tube along the inner tube wall. When the water in the pipe is absorbed heat, the temperature rises and the specific gravity decreases and rises, forming an upward motive force and a thermosiphon system. As the hot water moves up from time to time and stores in the upper part of the water storage tank, and the lower temperature water is added to the other side of the pipe from time to time to reciprocate, eventually the whole tank water rises to a certain temperature. Flat-plate water heaters, generally split water heaters, the medium in the collector plate due to the natural cycle of thermal siphon, solar radiation in the collector plate heat transfer to the water tank in time, the water tank through heat exchange (jacket or coil) heat transfer to cold water. Medium can also be circulated through the pump to complete heat transfer.
2.循环管路
2. Circulating Pipeline
家用太阳能热水器通常按自然循环方式工作，没有外在的动力。真空管式太阳能热水器为直插式构造，热水经过重力作用提供动力。平板式太阳能热水器经过自来水的压力（称为顶水）提供动力。而太阳能集中供热系统均采用泵循环。由于太阳能热水器集热面积不大，思索到热能损失，普通不采用管道循环。
Household solar water heaters usually work in a natural circulation mode without external power. Vacuum tubular solar water heater is directly inserted structure, hot water through gravity to provide power. Flat-panel solar water heaters provide power through the pressure of tap water (called top water). Pump cycle is used in solar central heating system. Because the solar water heater collector area is not large, considering the loss of heat energy, pipeline circulation is generally not used.
3.顶水式运用过程
3. Top-water application process
平板式太阳能热水器为顶水方式工作，真空管太阳能热水器也可实行顶水工作的方式，水箱内能够采用夹套或盘管方式。顶水工作的优点是供水压力为自来水压力，比自然重力式压力大，特别是装置高度不高时，其特性是运用过程中水温先高后低，容易控制
，运用者容易顺应，但是请求自来水坚持供水才能。顶水工作方式的太阳能热水器比重力式热水器本钱大，价钱高。
Flat panel solar water heater works in top water mode. Vacuum tube solar water heater can also work in top water mode. Jacket or coil can be used in water tank. The advantage of headwater work is that the pressure of water supply is tap water pressure, which is higher than natural gravity pressure. Especially when the height of the device is not high, its characteristic is that the water temperature is first high and then low, easy to control, easy to adapt to the users, but the tap water is required to adhere to the water supply ability. The solar water heater with top water working mode has higher cost and higher price than gravity water heater.
