The systems of solar energy for the heating of the water can be used in multitude of buildings that require sanitary hot water, or a whole year of solar heating. The concentrator they can provide 13 kw/h or 44,000 BTU of thermal energy/hour. The applications that can be benefitted from the solar heating are: Buildings of Government, Hospitals, Schools, Swimming pools, Plants of turnpike, Hotels, Buildings of apartments, Greenhouses, Free-mills, The desalination plants, aquatic laundries, centers, Breweries, Hospitals. Due to the variable of power and energy of the sun, it is necessary to know the amounts of consumption, the profile of consumption and the wished temperature of the hot water that it is required for the sizing of a solar system of energy. SolarTron Systems of Energy has a calculator for its distributors whom the amount of necessary solar concentrators on the basis of the amount of water, the initial temperature of the water and the temperature wished shows of water.This is an excellent tool for him people of sales, because the majority of the companies does not know the amount of energy that use.

With regard to the solar concentrators there are two main options: an axis of pursuit and 2 axes of pursuit.The systems with a pursuit axis they concentrate the solar light on a tube absorber in the focal line of the concentrator, whereas the system of pursuit of two axes focuses rays of the sun in a focal point.The applications that need the water to temperatures among 80-90 degrees use 300 million MWh to the year in the EU.What represent 8% of the energy demand.The chemical industry, the wastebasket, and the industry of food processing consumes great part of this heat. The advantages of the solar concentrators are that they are not affected by the heat stagnation .In the systems conventional collectors, if a shutdown takes place (for example, if the heat is not eliminated, or if a component fault) and soon with the purpose of to avoid the stagnation, it is needed several measures basic that must be incorporated (like expansion glasses).On the contrary, the solar concentrators that to use the solar pursuit must make use of routines of safety control, that desenfoca the collector to avoid that the temperature of stagnation is exceeded.Nevertheless, the suitable safeties, like flow indicator, are necessary to guarantee that the flow of the fluid of heat transference through the absorption, and therefore the heat elimination, with the purpose of to avoid the overheat of the system. SolarBeam uses external interchangers.The heat exchangers can be made of plates or tubes.The heat generators warm up the flow of some on others in crosscurrent.Advantages of the external heat exchangers are: – The capacity of heat transference is superior to the one of the internal heat exchangers – Almost there is no reduction in the yield of the heat accumulation – Several applications can be benefitted from a unique interchanger. Disadvantages of the external heat exchangers – They are more expensive than the internal heat exchangers – In the majority of the cases they need a pump additional water that is required in the secondary circuit of the heat exchanger.Therefore, they are not an option for the thermosiphon systems.
