Research On The Optimum Selection Of Air-Conditioner Heat/Cool Sourses And The System Design

The scheme selection method for the air-conditioner heat / cool sources is an important decision-making stage during the design of the air-conditioning system. How to select the optimized model scheme for the air-conditioner heat / cool sources based on the local conditions has become the focus of the engineers and users, which is also an important factor affecting the general society energy consumption and project investment.The main work is as followed:(1) Through an investigation and research of the heat and cool sources,analyze and compare some usual types of chillers and boilers in terms of primary energy ratio,and the influence to atmosphere of the chillers and boilers.(2) By use of the theory of the cost of year, calculate routine cost,depreciation cost every year, analyze economic condition of chillers and boilers under different price of energy.(3) In order to synthetically appraise the heat / cool sources scheme from multi-angle, multi-objective decision method in system science is introduced to the estimated process of the heat / cool sources schemes. This method makes up for some deficiency in the course of selecting chiller and makes the course of choosing and boilers more scientific and systemic. Through the comparison of the selection methods for the schemes of the air-conditioner heat and cool sources, the ideality point method is selected for its simple and practical merit. Establish the optimized selection model based on the scheme selection of the air-conditioner heat and cool sources and improve the array of estimation, which is the base in the software development of this optimized model.(4) With the analysis of the above theory and investigating information, design a set of software for comparing the performance of different types of chillers and boilers. So the users can obtain the most optimum design.
