Different heating methods of rural northern indoor thermal environment simulation analysis

With the rapid development of the rural economy, social progress and indoor heating methods also will be diversified, but given the limitations of technical means, resulting in lower rural energy efficiency, energy consumption is rising. To achieve the purpose of building energy efficiency in rural areas, two common ways of heating in rural areas are to compare. Select the same farm house kang - firewall and kang - soil heating in two different heating methods comparative analysis and apply fluid dynamics software to simulate two heating methods on the indoor temperature field, comparing two ways of heating of the room temperature at different heights. Kang - firewall in a joint operation is better than kang - soil heating joint operation on indoor temperature distribution, it was more uniform high comfort, you can save about 424Kg of standard coal annually. Compared to soil heating that firewall has a higher thermal efficiency and it is an energy efficient way of heating buildings in rural. Firewall heating consistent with sustainable development concept, which use renewable energy as fuel for lower cost. In- depth study can be important for social, environmental and economic value.
