余热利用部分一��又称热电冷联供系统�是指以燃料（燃气、燃油等）为能源，并同时满足区域建筑物内的电、热、冷需��的能源供应系统，通常由发电机组�溴化锂吸收式冷（热）水机组和换热设备、电气控制设备等组成。热电冷联供系统将高品位能源用于发电，发电机组排放的低品位能源（烟气余热、热水余热）用于供热或制冷，实现能源的梯级利用，提高能源的综合利用率�?/DIV>
实际应用中，一��在燃气发电机组发电的同时，以机组废气的热量为能源，烟气�过特制的热交换系统加热介质水，使水温达到规定温度，然后制热或通过溴化锂冷水机组制冷，通过风机盘管空调器给房间制冷或供热�一��的废气余热利用流程图如图3.3所���?/DIV>
Cogeneration system
Cogeneration system also called combined heat & power system (CHP). It is a power supply system to burn fuels (gas and gasoline, etc.) as energy source and meets the demand of building in certain areas for electricity, heat and cooling of. Generally, this system is consisted of generator set, lithium bromide cooling water unit, heat exchanger, electrical control equipment, etc. the high quality energy source is to generate electricity, meanwhile low quality energy ( waste heat fume, waste water heat) from generator set is to for cooling or heating. By this method, energy is utilized much efficiently.
In practice, while the generator set operates to generate electricity, its exhaust heat from the gen-set flows into the special heat exchanger to heat water inside up to specified temperature. Heat water energy is blown into room in winter through the piped conditioner. Heat water is delivered into a lithium bromide cooling water unit. After treatment there, air conditioning is delivered to rooms through the piped conditioners. Please refer to the flow chart of exhaust heat utilization in fig. 3.3 .
