While differing in the number of circulating circles, these systems are characterized by a number of common characteristics. Firstly, it’s total operating principle based on natural circulation. Another common characteristic between the direct and indirect solar systems with natural circulation is the use of an additional source of energy. In the form of electrical or other heater he installed in the battery container. When the intensity of solar radiation is insufficient to heat water in the tank to the desired values, such as prolonged or turning cloudy in winter, the heater turns on automatically and dozagryava water to the required temperature.


Collector connection


In this paper we continue the current theme for the production of hot water with solar collector systems with forced circulation of the coolant.

Forced circulation systems are more effective


A key element in systems with forced, called and forced circulation of the coolant is pump. Is advisable to use more automation to monitor water temperature in the battery nikelab roshe two leather vachetta tan , which is because the system runs continuously, even in the absence of sunlight, for example at night or in cloudy weather. Therefore, instead of heat, water will cool the battery. It is to not allow this element of the system are sensors to monitor water temperature in the battery. Depending on the signal generated by them, the pump will turn on only when the water temperature in the battery is lower than the collector or depending on the desired temperature. Pump and additional automation, of course, expensive system. The larger number of elements of the systems with forced circulation determines in its complicated installation, setup and repair. But these systems are characterized by higher efficiency, allowing to reduce the collector area as the extraction of heat from the unit area is larger.


Unlike systems with natural circulation in the pump header systems nikelab roshe two leather tan , there is no requirement for installation of the battery court higher than the collector. The installation of the collector could be done on the roof. A battery can be mounted anywhere in the building.


Some experts recommend that the battery has a capacity adequate to collect the required amount of hot water for several days. It is possible to use an additional energy source to compensate for the inability of the collectors to produce hot water at the required temperature for longer periods of unfavorable weather conditions. In the process of designing solar systems for year round use, necessarily relies on the battery with auxiliary heating, mostly electric. If the battery has two poles, may be incorporated into the boiler. Logically, the battery and pipes should be insulated to prevent heat loss.

Direct solar installations with forced circulation are effective but not suitable for geographic areas with hard water, and for applications in which water has a higher acidity. Their development is appropriate in areas with mild climates where temperatures rarely fall below zero degrees. It is recommended to ensure protection against freezing of water. Indirect solar systems with forced circulation are suitable for regions with long periods of subzero temperatures.


Whichever type of solar system – with natural or forced circulation, the heat in the collector circuit is good to be chemically purified water, and can be used antifreeze based on ethylene glycol or propylene glycol. It is recommended that solar systems be constructed as indirect systems, ie with a separate collector kortur as thus provides a longer lifetime of the collector.

Collectors are part of the architecture of the building.


In comparison, direct systems the risk of corrosion is much greater. In the design of solar systems to achieve high efficiency, ie reached the maximum utilization of solar energy collectors on should take account of complex factors. Among them, along with the type of solar installation and type of collectors are and how their assembly, including the location, orientation and angle of mounting of collectors.


When choosing a location for mounting the collector is well to bear in mind that it absorbs the largest amount of solar energy, where the plane is perpendicular to the direction of the sun. In different seasons, however, the angle at which sunlight reaches the Earth at a certain point itCorey Kluber W.
