PAGE 大型制药厂热电冷三联供工程设计研究 摘　要:热电冷系统利用吸收式制冷技术给设备供暖和制冷。利用现有热电联产系统发展集中供热,供电和供冷为一体的能源综合利用系统。该系统将溴化锂吸收式制冷机引入到热电厂的热电联产系统中,可增加热电厂的夏季热负荷,从而使冬夏热负荷平衡,保证热电厂更经济高效地运行。本文根据热电冷三联供节约能源的原理，对一座较大型的药厂进行工程设计研究，结合药厂对温度，湿度要求高的特点，进行详细计算，仔细论证，对制冷设备参数提出要求。通过调查和计算,将热、电、冷联产与热电和冷量分供系统加以比较,表明该系统不但可节能,而且具有增加电能生产和保护环境的效益。 主题词:热、电、冷三联供;吸收;环保 Electricity Heat and Chilled Water Congenerating System in large-scale pharmaceutical factory is provided in the engineering design research. Abstract: Combined heat and power(CHP) systems often use absorption technology to supply heating and cooling to a facility.This paper puts forward an energy comprehensive utilization system, Electricity Heat and Chilled Water Congenerating System(EHCWCS).This system introduces H2O-LiBr Absorption Refrigenerating Machine into Heat and Power Plant to increase the heat load of the plant in summer,which can balance the heat load in summer and winter, so Heat and Power Plant can run in a high efficiency. This text is according to the thermo-electricity cold triple-generation system provide the principle that economize the energy, proceeding to a large pharmaceutical factory the engineering design study, joining together the pharmaceutical factory to the temperature, the degree of humidity requests the high characteristics, proceeding the detailed calculation, carry on detailed calculation, put forward the request to the refrigeration equipments in system parameter. The result of analysis states that this system can not only save energy, but also increase the output of electricity of Heat and Power Plant and protect environment.
