| With the development of people's requirement for comfortable in architecture, the consumption for heating energy will be increasing. In recent years, the most energy sources consumption is such as coal,petroleum and so on. The discharge of pollutants such as SO2 and CO2 will be lead to environmental pollution. It's also influence the greenhouse effect. With the development of energy development and increasingly acute of environment, the solar energy should be paid more and more attention.This paper firstly introduces the version of the solar water system, the critical component - the version and component of heat collector and the fundamental of the low temperature solar water for floor heating. Then analyzes the feasibility of the low temperature for floor heating take the case of Luoyang. In this paper, we also combine two categories of architecture in comparing low temperature solar water for floor heating with regular heating sources. Then we carry out analysis of the economic benefit. Because of the high initial cost of solar heating, just for heating request, shortly busy period, and the price of general energy sources in Luoyang is low, the implicit price of solar heating is not economical. This paper then outlines solar heating and domestic hot water. Then we conclude that with the increasing of water consumption and using period, the economical of solar heating is competitively strong.In the end, this paper analyses the economization and conservation benefit of solar heating system and domestic hot water. The conclusion indicates that the combination of solar heating and domestic hot water will increases the economical of the solar heating system. It's economization and conservation benefit is also unparalleled. The best scheme of villa is solar system combining centralizing hearing, and the best scheme of administrational building is solar system combining electrical heating. |
