辽宁阜新某商场中央空调系统设计与节能探讨

Discussion on the design &energy-saving of central air-conditioning system in a store of Fuxin in Liaoning

结合辽宁阜新某商场中央空调系统工程实例,从中央空调系统设计和节能两个角度探讨.中央空调系统设计主要包括工程概况、空调系统工作原理和主要设备三个方面.空调系统节能主要从夏季调整室内温湿度参数、过渡季节采用冷却塔供冷两种方案分析.进一步得出结论：夏季将室内温度设定值提高1～2℃,节能比例至少为12.7％,至多为37％;过渡季节采用冷却塔节能方案,尽管存在管路堵塞问题,但从整个空调系统的运行成本来看,还是可行的.

Based on the central air-conditioning system project from a store in Fuxin, we discuss the problem of its design and energy-saving aspects. The design of the central air-conditioning system mainly includes the layout of the project, the principles of its operation and its main facilities. Its energy-saving aspect is achieved by adjusting the indoor humidor parameters and using the cooling tower to cool in transitional season. Further conclusions are if the set temperatures of indoors are increased 1 to 2 ℃, the rate of energy-saving can be up to at least 12.7%, and even 37% to the most. Although using the cooling tower to save energy in the transitional season can cause line congestion, it is still acceptable concerning the running cost of the whole system.
