Optimization of cold and heat source design of air conditioning system for WuXi gaoke building

Abstract

The construction area of the building is 9000㎡,which composition of two underground floors and the floors. This design is aim at select the best cold and heat resource.First, I have compared various cold and heat source in the paper,and focused on ice storage design.Including the ice main equipment selection,Plate heat exchanger calculation and calculation of various auxiliary equipment selection.Then compare various cold and heat source of investment and running costs,Considering environmental issues.Final,select the best cold and heat source.

Key Words: Cold and heat source; Ice storage; Running costs
