Design Optimization For Water System Of Air-Conditioning

The architecture design of water system is occupied a important position in air conditioning system design, and is also an existing most faults part of air conditioning system. Nowadays, more and more people is concerned to save energy of buildings, but how to make the water system of the air condition more efficiently and more economically work, building the foundation for energy saving of air conditioning system and building, is an area for people to discuss and research. In this paper, the author has integratedly given the method of optimization of air conditioning water system and written computer programs in order to solve the problems of water system , perfect the design and make the system work more efficiently and more economically.The experience of balancing pressure method of municipal engineering pipe network gives the author inspiration. But there are something different between the pipe network of air conditioning water system and urban water network. To discriminate the two pipe networks, adds penalty function to target function of pipe network optimized problem of air conditioning water system. By using the genetic algorithms, the author solves the pipe network optimized problem and gets the satisfactory solution with few projects comparing. In this paper, also provides the method to get the simulated function of pump performance curve and writes related computer program to let the user get the operating point data of pumps easily, then select suitable pump for water system. This paper also establishes a fuzzy judgment model of water system choosing based on fuzzy mathematics basic theory to realize the optimisation of whole air conditioning water system.Based on the thought that the optimization is not the optimization of a part of water system but of the whole water system, proposes optimization of pipe network, opti- mization of pump selection and water system project choosing. Also provides the method and direction for the successive research of air conditioning water system.
