Advantages Of Using Active Closed Loop Solar Hot Water System,chick here
An active closed loop is a type of solar hot water system that uses a heat-transfer liquid to collect heat from the sun. Once the heat is collected, a heat exchanger transfers it to household water. This type of solar heater uses electric pumps,Hogan Uomo Oympia Scarpe Colore Chiaro, valves, and controllers to circulate the heat transfer fluid. The most commonly used heat transfer fluid is called a polyperene glycol-water anti freeze mixture. This mixture makes the active closed loop system to be effective in cold areas that are subjected to freezing temperatures. This type of solar heater is popular because of its numerous advantages.
Like mentioned in the above paragraph, the active close loop solar hot water system can be used in areas that experience temperatures below freezing. Good examples of such areas are the Scandinavian countries such as Siberia. Anyone with a little knowledge in chemistry knows that metals contract in very low temperatures and expand in high temperatures. Pipes can thus burst in cold temperatures,read more, to prevent this; the active closed loop system uses a heat transfer liquid that has a freezing point lower than that of water. Hence,Hogan scarpe donna 524 Nero, pipes are protected from the adverse cold.
The active closed loop solar hot water system has a storage tank for heat collected. This means that not all the heat is used to heat water once. In a scenario where a solar heater system lacks a heat storage tank, water may be heated to evaporating temperatures especially when kept for a long time. The active loop system also has separate pipes for the heated water and the cold water. This ensures that the two waters do not mix. Like most types of solar heaters, the closed loop has a storage tank for heated water.
Another advantage of using the active closed loop solar hot water system is the fact that it can be completely is powered by the sun. In addition, the photovoic pipes, which are commonly used in the system, run at a variable speed making the system run as efficient as possible. Albeit all this,Hogan Donna Fuxia Rosso Interactive 2012 ouelet online, the closed loop system is not void of disadvantages. For instance, its usage of a heat exchanger, adds some inefficiencies to the system that must be taken in to consideration during the design and sizing stage. Nevertheless, it is fair to say that the advantages of the system surpass its disadvantages. 相关的主题文章：
