PAGE PAGE 65 珠海市高新区热电冷三联产系统设计 摘 要 热电冷三联产是热电联产的最近发展，人们比较熟悉的是热电联产，也就是在一个过程中同时生产电力和热力。而热电冷三联产就是在热电联产的基础上，收集蒸汽产生的热量，通过吸收式制冷机组，或是离心式冷冻机来制冷，从而发展出热电冷三联产。 经济发展和人类生活水平的提升，使得节能措施变得越来越重要，同时对于环境保护的需求也随之提高，并且对相关的技术和管理模式进行了合理的改进和完善，促使了热电冷三联产技术的迅速发展。 此次设计，通过已知的燃料、水质、气象和热负荷资料，合理地对锅炉汽机进行选型，以及对整个系统进行设计和相应的选择设备，从而进行锅炉热平衡的计算；汽水系统的设备选择与计算，送汽与供水主要管路管径的计算；换热站中换热器的选择与计算；管道敷设与保温的计算；吸收式制冷机组的选择与计算；热经济性评价等。 关键词：吸收式制冷；热电冷三联产；锅炉；热经济性评价 Design of thermoelectric cooling triplex system in Zhuhai high-tech zone Abstract Thermoelectric cooling triple generation is the recent development of thermoelectric cogeneration, people are familiar with is thermoelectric cogeneration, that is, in a process at the same time to produce electricity and heat. And thermoelectric cooling triple generation is based on thermoelectric, the use of steam heat source, the use of absorption refrigeration units, or the use of engine driven centrifugal refrigerator to refrigeration, so as to develop thermoelectric cooling triple generation. With the development of economy and the improvement of peoples living standard, energy-saving measures become more and more important, and the demand for environmental protection also increases. In addition, relevant technologies and management modes have been reasonably improved and improved, which has promoted the rapid development of thermoelectric and cooling tri-generation technology. This design, through the known fuel, water quality, meteorological and thermal load data, reasonable boiler turbine selection, as well as the entire system design and the corresponding selection of equipment, so as to calculate the boiler heat balance; The equipment selection and calculation of the soda water system, the calculation of the main pipe diameter of the steam supply and water supply pipeline; Selection and calculation of heat exchanger in heat exchange station; Calculation of pipe laying and heat preservation; Selection and calculation of absorption refrig
