An Analysis and Evaluation on Adaptability of Wall-hung Mounted Gas Boiler between Indemnificatory Residential Buildings in Beijing

摘要

With an increasing emphasis on easy operation, flexible adjustment and high energy efficiency, the application of the wall-hung gas boiler are becoming more widely considered among the residential building as a competitive or alternative way to district and central heating in Beijing. It meets the implementation of the policies in twelve-five year plan of China: improving Beijing's environment and future sustainable transform on its coal-based energy structure. A survey of the heating way of indemnificatory housing, price-fixed housing and affordable housing in Beijing is proposed. The results show that the heating area using the wall-hung gas boiler in the resident building is 55% of the total heating area in Beijing and 67% of the total heating area in new buildings. Then, the adaptability between the household wall-hung gas boiler heating way and other heating ways is compared. The energy efficiency, initial investment, operating cost and user satisfaction are discussed. The final analysis is then evaluated by a panel of experts to determine its accuracy and potential for use in a greenway development plan of heating way in Beijing.
