地下水源热泵的最优化研究

为了根据不同的使用条件，进一步提高地下水源热泵机组的性能，通过对机组运行特性的分析，依据技术经济优化准则，以年度费用总额为目标函数，建立系统综合优化数学模型，并编制了计算程序。在保证机组安全可靠地满足建筑物冷热负荷需求的前提下，根据不同的地下水温度与深度，对系统关键运行参数及部件进行了优化选择计算。该方法兼顾了供热供冷运行的可靠性与经济性，可实现系统内各部件的最优匹配。与传统设计方法相比，该方法能大幅度改善机组的性能。

OPTIMIZATION OF A GROUNDWATER-SOURCE HEAT PUMP

This paper puts forward an integrated optimal mathematical model with an objective function of the annual total costs by analyzing the operating characteristics according to technical and economic optimal principle for improving the performance of the groundwater source heat pump. A computation program was also developed. On the premise of ensuring the unit to fulfil the heating and cooling requirements of buildings, this model is used to calculate and optimize some key operating parameters and components according to different temperature and depth of the groundwater. It combines the reliability and economy of heating and cooling and achieves the most optimal match of each part of the system. The present method will lead to a greater improvement in the performance of the heat pump than traditional method.
