天津农村住宅不同清洁采暖方式室内环境评价

Indoor Environment Evaluation of Rural Houses with Different Clean Heating Systems in Tianjin

天津农村住宅冬季采暖方式主要为空气源热泵热风式、空气源热泵暖气片式、燃气壁挂炉暖气片式、生物质锅炉暖气片式、洁净煤锅炉暖气片式。为研究不同采暖方式对室内环境的影响,本文采用线性回归和灰色关联方法分别对不同采暖方式下居民热舒适性及室内空气品质进行分析。结果表明:空气源热泵热风式、空气源热泵暖气片式、燃气壁挂炉暖气片式、生物质锅炉暖气片式、洁净煤锅炉暖气片式下,居民的热感觉投票从-1到+1所占比例分别为81%,73%,66%,74%,76%;热中性温度分别为20.09℃,18.48℃,18.21℃,18.24℃,18.88℃;相同热感觉投票下,生物质锅炉暖气片式热舒适性最高;在热中性温度时,居民期望维持现有热环境的百分比最高;室内空气品质依次为轻污染、未污染、未污染、未污染和中污染。

The main heating systems in rural residences of Tianjin include: air heating equipment based on air source heat pump,water heating equipment based on air source heat pump,water heating equipment based on natural gas boiler,water heating equipment based on biomass boiler,and water heating equipment based on anthracite boiler.To investigate the influence of different heating methods on indoor environment,the linear regression method and the gray correlation method were used to evaluate indoor environment.The results showed that: a large percentage of thermal sensation votes( TSVs) for the five heating systems were located in the range from -1 to + 1( 81% for air heating equipment based on air source heat pump,73% for water heating equipment based on air source heat pump,66% for water heating equipment based on natural gas boiler,74% for water heating equipment based on biomass boiler,and 76% for water heating equipment based on anthracite boiler).The thermal neutrality temperature of the five heating systems was 20.09 ℃,18.48 ℃,18.21 ℃,18.24 ℃ and 18.88 ℃ respectively.The water heating equipment based on biomass boiler had the highest thermal comfort in the same TSVs.The highest percentage of residents expected to maintain the existing thermal environment at thermal neutrality temperature.The indoor air quality of the five heating systems was lightly polluted,uncontaminated,uncontaminated,uncontaminated and moderately polluted.
