太阳能热水器的水流方式有什么不同?
2023-09-12
济南太阳能配件厂家提示我们,不同太阳能热水器的水流方式也有很大的区别,从水流方向可分为:自然循环式太阳能热水器、强制循环式太阳能热水器和直流式太阳能热水器。
Jinan solar fittings manufacturer reminds us that the water flow mode of different solar water heaters is also very different, from the direction of water flow can be divided into: natural circulation solar water heater, forced circulation solar water heater and direct current solar water heater.
自然循环式:分为自然循环和强制循环。自然循环太阳能热水系统是依靠集热器和储水箱中的温差,形成系统的热虹吸压头,使水在系统中循环;与此同时,将集热器的有用能量收益通过加热水,不断储存在储水箱内。
Natural circulation: It is divided into natural circulation and forced circulation. The natural circulation solar hot water system relies on the temperature difference between the collector and the water storage tank to form the thermal siphon head of the system, which makes the water circulate in the system. Meanwhile, the useful energy income of the collector is stored in the water storage tank continuously through heating water.
强制循环式:强制循环太阳能热水系统是在集热器和储水箱之间管路上设置水泵,作为系统中水的循环动力;与此同时,集热器的有用能量收益通过加热水,不断储存在储水箱内。强制循环系统可适用于大、中、小型各种规模的太阳能热水系统。
Compulsory circulation: Compulsory circulation solar water heating system is a water pump installed in the pipeline between the collector and the water storage tank as the circulating power of water in the system. Meanwhile, the useful energy income of the collector is stored in the water storage tank continuously through heating water. The forced circulation system can be applied to large, medium and small scale solar water heating systems.
直流式:直流式太阳能热水系统是使水一次通过集热器就被加热到所需的温度,被加热的热水陆续进入贮水箱中。优点是与强制循环系统相比,不需要设置水泵;与自然循环系统相比,贮水箱可以放在室内;容易实现冬季夜间系统排空防冻的设计。缺点是要求性能可靠的变流量电动阀和控制器,使系统复杂,投资增大。
DC type: DC type solar water heating system enables water to be heated to the required temperature once through the collector, and the heated hot water enters the water tank one after another. Compared with the forced circulation system, there is no need to install water pumps; compared with the natural circulation system, the water tank can be placed indoors; it is easy to realize the design of system emptying and anti-freezing at night in winter. The disadvantage is that variable flow electric valves and controllers with reliable performance are required, which makes the system complex and increases investment.
