太陽能熱水器的工作原理介紹！
2023-09-12
太陽能作為一種新興的可再生能源，被普遍應用于我們的日常生活中。在光熱轉(zhuǎn)換中，當前應用范圍廣、技術成熟、經(jīng)濟性好的是太陽能熱水器。下面濟南太陽能配件公司就為大家提高一下太陽能熱水器的工作原理，希望對大家有所幫助！
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.吸熱過程
1. Endothermic process
太陽輻射透過真空管的外管，被集熱鍍膜吸收后沿內(nèi)管壁傳送到管內(nèi)的水。管內(nèi)的水吸熱后溫度升高，比重減小而上升，構成一個向上的動力，構成一個熱虹吸系統(tǒng)。隨著熱水的不時上移并貯存在儲水箱上部，同時溫度較低的水沿管的另一側(cè)不時補充如此循環(huán)往復，終整箱水都升高一定的溫度。而平板式熱水器，普通為分體式熱水器，介質(zhì)在集熱板內(nèi)因熱虹吸自然循環(huán)，將太陽輻射在集熱板的熱量及時傳送到水箱內(nèi)，水箱內(nèi)經(jīng)過熱交流（夾套或盤管）將熱量傳送給冷水。介質(zhì)也可經(jīng)過泵循環(huán)完成熱量傳送。
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.循環(huán)管路
2. Circulating Pipeline
家用太陽能熱水器通常按自然循環(huán)方式工作，沒有外在的動力。真空管式太陽能熱水器為直插式構造，熱水經(jīng)過重力作用提供動力。平板式太陽能熱水器經(jīng)過自來水的壓力（稱為頂水）提供動力。而太陽能集中供熱系統(tǒng)均采用泵循環(huán)。由于太陽能熱水器集熱面積不大，思索到熱能損失，普通不采用管道循環(huán)。
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.頂水式運用過程
3. Top-water application process
平板式太陽能熱水器為頂水方式工作，真空管太陽能熱水器也可實行頂水工作的方式，水箱內(nèi)能夠采用夾套或盤管方式。頂水工作的優(yōu)點是供水壓力為自來水壓力，比自然重力式壓力大，特別是裝置高度不高時，其特性是運用過程中水溫先高后低，容易控制
，運用者容易順應，但是請求自來水堅持供水才能。頂水工作方式的太陽能熱水器比重力式熱水器本錢大，價錢高。
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.
