What is the solar driver?
As far as the sun's hot water systems are concerned, the solar driver is part that controls the pump that moves the top of the top through the collector. Solar regulators differ in sophistication and functionality, but all include at least two temperature scan ports and one output port that controls the pump. More complex controllers may include additional electronic functions that improve system efficiency or digital readings that show important system information. Depending on the range of functions included, the solar controller may be included in the heating system itself or in the remote location of the available user.
The heating of solar water is constantly growing in popularity around the world on the back of the cost of spiral. These systems generally consist of a collector and water tank. Water or specially formulated fluid of heat transfer (HTF) is exposed to sunlight through a large surface area of the collector. The heated liquid then spreads into the north ways into the water reservoirthat, where it transmits heat to the contents of the tank. Obviously, this movement of the fluid between the collector and the water tank is essential for the effective operation of the hot water system, but also serves as a safety measure to ensure that the collector does not overheat at the time of low demand.
In active hot water solar systems, this motion of liquid is achieved by the electric pump operated by a solar control. The controller has several temperature scan ports that collect data from temperature probes located at different points in the system, especially in the collector and tank. When fluid circulation is required, the controller sends the signal via the output port to activate the relay that switches to the pump again. When the system temperatures reach a point where the circulation is no longer required, the controller reduces the power supply to the relay and turns off the Again pump.
This basic function can be achieved using very simple electronic circuits,that are often built into collectors or motor capsules. However, many units of solar controls have additional functionality, in the form of other sensors and controls to prevent energy waste due to the abbreviation pump. This level of inspection is usually achieved by including microprocessors in the controller. This type of controller is generally located where there is easy access, and often includes a digital display that can provide basic system information. Many solar control models also include controls of suppression for manual start and pump stop.
