摘要
结合某工程项目附近有大量地下矿坑水的实际情况,比较分析中央空调水系统(冷水机组+热水锅炉)、地下水源热泵空调系统、水源多联机空调系统及空气源多联机空调系统这4种常见空调形式在本项目中的适用性与可行性.借助设计分析软件对项目建筑进行负荷计算、机房提效寻优、建模并模拟制冷运行工况,基于供暖运行负荷及运行时间计算冬季系统运行费用;通过动态年值和运行阶段碳排放分析,结果表明:在有低品位能源可利用的前提下,水源多联机空调系统方案的经济性和碳排放强度具有明显优势.
Abstract
Combined with the actual situation in a project that there is a large amount of pit water,the applicability and feasibility of four common air conditioning forms,namely central air transfer system(chiller+hot water boiler),underground water source heat pump air conditioning system,water source multi-line air conditioning system and air source multi-line air conditioning system,are compared and analyzed in this project.With the help of design and analysis software,load calculation,efficiency improve-ment and optimization of engine room,modeling and simulation of refrigeration operating conditions of the project building,and calculation of winter system operating costs based on heating operating load and operating hours;Through the analysis of dynamic annual value and carbon emission during operation,the results show that:under the premise of low grade energy available,the water source multi-line air conditioning system has obvious advantages in economy and carbon emission intensity.
