水源热泵综合节能技术的工程应用分析

摘要

Water source heat pump is an application technology of renewable energy resource,which has advantages of improving efficiency of machine and reducing operation energy consumption.Taking a real project as an example,several problems in designing surface water source heat pump systems are discussed.The integrated application of WSHP and other technologies,including district heating and cooling,two-grade pump and variable water volume,can not only achieve the advantages of WSHP,but also the total energy efficiency of the HVAC system can be improved greatly.The comparison analysis between traditional system and WSHP system of this project concludes that combining other energy efficient technologies with WSHP together based on a detail analysis of conditions can reduce the operation energy consumption by 46%.%水源热泵技术是可再生能源利用技术,具有提高机组效率和降低系统运行费用的优点。以实际工程为例,研究了地表水水源热泵空调系统设计中的具体问题。结合工程具体情况,探讨了在应用水源热泵技术的同时,将集中供冷供热技术、二次泵技术、变流量技术等其他多项节能技术综合应用,不但能更有效地发挥水源热泵技术的优点,并能大大提高空调系统的能效。对常规空调系统形式与水源热泵空调系统形式进行了技术经济比较,结果表明该工程水源热泵技术与其他节能技术综合应用可减少全年运行能耗约46%。
