Summary

In order to determining the relevance between thermal comfort and key energy design elements during energy-saving design process, the method of extracting energy design factors of air conditioning and calculating its weight is proposed. The house of quality based on thermal comfort is built with the energy-saving design frame. The thermal comfort requirements are converted to function and weight of air conditioning. The energy characteristic of the function is analyzed, and the extract means of energy design factors is provided based on the relation of functions with energy. The method of calculating influence degree of energy design factors on thermal comfort and energy consumption is also put forward. Taking the household air conditioning as a case study, the energy design factors based on thermal comfort are extracted. Two coupled factors, volume efficiency and heat transfer coefficient, are decoupled, and the influence coefficient of energy design factors on thermal comfort and energy consumption in overall layer are calculated. The comprehensive influence coefficient in descending order is compressor power,system control mode, ventilation quality and heat exchange amount.
