摘　　要：分析了天津地区发展燃气空调的有利因素,探讨了燃气直燃式溴化锂吸收式冷热水机组(燃气直燃机)的特点。通过工程实例,对以燃气直燃机、集中供热+电制冷、燃气锅炉+电制冷、空气源热泵+燃气调峰锅炉4种冷热源的经济、环保性进行了比较。The favorable factors for developing gas air conditioner in Tianjin region are analyzed,and the characteristics of gas direct-fired lithium bromide absorption water chiller-heater units are discussed. By means of engineering examples, a comparison is made on the economy and environmental protection for four cooling and heat sources, including gas direct-fired machine, centralized heat-supply plus electric refrigerating, gas boiler plus electric refrigerating and air source heat pump plus gas peak-shaving boiler.
