What are the application of solar energy in house architecture

It wasn't about the application of solar energy, the energy problem these years begin emerging cases, at least in our country, has a history of, the earliest application of solar energy can be attributed to the more than two thousand years ago during the warring states period, at that time people started to use steel all around mirrors focus sunlight to ignition, use the sun to dry agricultural and sideline products. At that time, of course, the purpose of using solar energy and solar energy development now, however, as the energy utilization, there is no doubt that is positive and effective.

first, hot water system. Early solar energy application is the most widely used to heat the water, the world millions of solar water heating device. Solar water heating system main components including collector, storage device and the circulation line of three parts. In addition, there may be secondary energy device ( Such as electric heaters, etc. ) To supply without the use of sunlight, in addition to fair can have forced circulation use of water, to control the water level control electric parts or temperature of the device, and received a load of pipeline, etc.

second, lighting system. Solar street lighting is essentially a photoelectric conversion system, field called & other; Silicon wafer surface photovoltaic modules & throughout; 。 Its working principle is through the silicon wafer after receive the sun's rays into electricity, then stored in the storage battery, and then by the light switch control, can automatically light up when the day is black, and automatically put out at daybreak. An application of the photoelectric conversion technology products & other; Solar energy lamp & throughout; Trenching is not influenced by power supply, don't bury a line, don't consume regular power and other characteristics, can be widely used in residential stair lighting, building external lighting and lighting inside the village road, grass, with the gradually reduce of non-renewable resources, solar lights, solar garden light will be widely used.

third, heating system. Solar energy heating system in general by hot components, thermal storage components, radiators and auxiliary heat source. Structure can be divided into natural and mechanical two categories, the former as the active heating, which is called passive heating. The so-called active solar energy heating system, namely installed solar collectors on housing, indoor storage tank ( Water as heat transfer medium system, thermal storage medium is hot water; Air as heat transfer medium system, thermal storage medium for pebble) And conventional radiator, the pipeline will them into heating system, the system of forced circulation, by a pump or fan heating medium. Passive solar heating, it is depend on the natural features of low Angle of the sun in winter, with the building structure itself to complete the set of functions of storage heat and heat release heat, heating system. In essence it is emphasizes the use of solar energy saving building, cost increase is not much, can benefit is remarkable, therefore, has become the world the mainstream of the promotion of solar energy heating technology.

4, air conditioning system. Current solar energy air conditioning technology is varied, mainly absorption refrigerating and photoelectric conversion power driven refrigeration. Lithium bromide - more mature technology Hydraulic epicuticular absorption refrigeration, at present already has been employed in some demonstration project, but because there are so many types of solar energy air conditioning technology, maturity is different also, in its application in residential construction is less.
