摘要
介绍了三峡大厦冰蓄冷低温送风变风量中央空调系统的设计概况,着重指出了其中的设计优化点和创新点。详述了该系统的优化设计思路及运行控制策略,计算得到该系统全年的运行耗电量和电费,并与常规电制冷系统进行了比较,指出该项目采用冰蓄冷空调系统尽管增加了耗电量,但是将为用户节省可观的运行费用。由于空调末端形式复杂,节能量计算难度较大,低温送风变风量末端的节能量有待观察。
Introduced design general situation of ice storage cold air distribution variable air condition system of Sanxia mansion, accentuated design optimization point and innovation points. Dilated optimized design thinking and control strategy in system, presentd all year running power consumption and operation electricity charges, and contrast with conven- tional electricity air condition system, and then indicated that the ice storage air condition system used at this project would save considerable running cost for user although increased power consumption. Due to the complex air terminal form, it＇s difficult to calculate quantity of energy saving, so the quantity of energy saving of cold air supply variable air condition system remains to be seen at the end of the quarter.
