【暖通专业实践论文】摘要： 阐述了利用热电联产热、锅炉房供热和废热驱动的各种冷热联供系统的能耗估算方法。对热电联产情况考虑了汽轮机进排气参数等条件的变化对供热供冷能耗的影响。给出了一定条件下各种系统包括热泵系统的供热供冷一次能耗率，并与常规系统作了比较。 关键字： 供热 供冷 热电联产 能耗
AbstractRepresents an energy estimation method for combined heating and cooling system (CHC) operated by heat from cogeneration systems or heating bollers and wasted heat, with consideration of effects of variation in inlet and outlet steam properties of the turbine on the heating and cooling energy consumption. Gives estimation of the primary energy ratio of heating and cooling for systems including the heat pump system and comparison with those for conventional systems.
Keywords heating, cooling, cogeneration energy, consumption

利用热能驱动的制冷其可回收利用各种低品位余热，从而在能量梯级利用中起着不可替代的作用。热制冷通常伴随着一个供热系统。由于共用了热源和其它一些设备，冷、热两部分互相联系成为一体，故称之为冷热联供。与采用电动制冷、热能供热的冷热分供相比，供热装置的冬、夏共用提高了它的全年得
