燃气空调机的环境影响探讨

本文讨论在城市使用燃气空调机的能源利用效率和环境保护问题.指出以燃气空调机取代电力空调机并不能必然地提高一次能源的利用效率,若燃气空调机把一次能源转换过程产生的污染物和余热的排放地点,转移到城市的建筑物和住宅,有关地区的空气质量因而恶化,而且,热岛效应的加剧将导致空调能耗明显增加.同时,燃气空调机的安装、运行受到资源和环境的制约.因此,在城市中心地区和中、高密度住宅区,应限制燃气空调机的使用.

Discussion of the Impact of Gas Air Conditioners upon the Environment

This paper discusses issues about energy utilization efficiency and environmental protect for gas air conditioners in urban districts,and points out that replacing electrical air conditioners by gas air conditioners could not inevitably improve primary energy efficiency,if gas air conditioners bring pollutants and waste heat exhaust into the urban districts during the primary energy conversion process,the air quality would be deteriorated,also enhanced heat island effect would certainly increase energy consumption for air conditioning.Meanwhile,installation and operation of gas air conditioners are limited by resource and environmental factors.Therefore,Gas air conditioners should be limited in central site,residence site of high- and medium-density in urban districts.
