Solar heating is divided into passive and active heating. Passive style refers to the ingenious management of internal space and external form based on the rational arrangement of the building's orientation and environment, as well as the appropriate selection of materials and structures construction without the use of mechanical energy. a technology that has a certain heating function for buildings.
Passive heating, the three major elements of passive heating technology are heat collection, heat storage and insulation. The main forms are: direct income type, heat collection and livestock heating wall type, additional veranda combined type, etc.
When heating is necessary, it is often when solar radiation is at its maximum. Sometimes water from solar energy doesn't heat, so what can be used for heating?
It is said that solar heating saves energy, but in reality many problems remain.
For winter heating, a huge solar heat collection system must be configured to meet winter heating needs. How can we consume the large amount of thermal energy generated by this system in summer? During the heating season, even with such a large solar heat collection system, it may not be able to provide the required heat. If there is no sun, other conventional energy sources will be consumed.
Solar hot water heating may look good, but in fact it may not be necessary.
When designing and installing systems solar hot water systems, consider them for year-round use, especially during the seasons. with good solar radiation. During the heating season, the temperatureAmbient temperature is high and the base temperature of water used for heating is also high, so the solar hot water system can meet the usage requirements most of the time. On a small number of rainy days, other auxiliary heat sources can be used for heating (at this time, the water temperature in the solar system is higher than that of the water in the faucet) to meet the usage needs. A solar water heating system combined with suitable auxiliary heat source heating is the most economical, reasonable and energy efficient.
