针对我国既有建筑暖通空调系统存在的问题,基于层次分析法建立暖通空调系统绿色改造评价指标体系,结合调查问卷结果,计算评价指标体系中各项指标的权重。既有建筑暖通空调系统绿色改造应从设备和系统的节能降耗、室内净化以及实现自然冷源、余热(余冷)、可再生能源的综合利用入手,能耗降低幅度、静态投资回收期、室内热湿环境改善是绿色改造效果的关键评价指标。
In view of the existing problems of HVAC system in our country, the index system of green reform of HVAC system based on Analytic Hierarchy Process (AHP) was established. Based on the questionnaire results, the weight of each index in the evaluation index system was calculated. The green retrofit of existing HVAC systems should start with the energy saving of equipment and systems, indoor purification and the realization of natural cooling, waste heat (cooling), comprehensive utilization of renewable energy, reduction of energy consumption, static payback period, Indoor hot and humid environment improvement is the key evaluation index of green renovation effect.
