说明水循环热泵系统由位于每个区域的单独水源热泵组成。热泵与一个公共循环水回路相连，该回路在冷却时充当散热器，在加热时充当热源。当冷却占主导地位时，回路中的水温升高。当加热占主导地位时，回路中的水温降低。描述了在一系列回路水温下对系统运行的检查，并指出了性能特征的趋势。在分析的基础上，提出降低系统能耗的回路水温建议。关键词:热泵，水热泵，加热，冷却，水温，优化，能耗引用:研讨会，ASHRAE Trans。1991年，卷。 97，第2部分

States that a water-loop heat pump system consists of individual water-source heat pumps located in each zone. The heat pumps are linked with a common circulating water loop that serves as a heat sink when cooling and a heat source when heating. When cooling dominates, the temperature of the water in the loop increases. When heating dominates, the temperature of the water in the loop decreases. Describes an examination of the operation of systems over a range of loop water temperatures and notes trends in performance characteristics. On the basis of the analysis develops recommendations for loop water temperatures that minimise system energy consumption.KEYWORDS: Heat pumps, water heat pumps, heating, cooling, water temperature, optimum, energy consumption
