三联供水(地)源热泵机组的应用

Application of trigeneration water-source (ground-source) heat pump unit

介绍一种水侧转换的三联供水(地)源热泵机组,其主要特点是将冷凝器分成以显热交换为主的一级冷凝器和以潜热交换为主的二级冷凝器。通过对该机组及系统技术方案的分析,以及机组能效比和性能系数的计算,认为该机组可以充分利用冷凝热的潜热和显热分别对生活热水进行梯级加热,不必采用高温工质就能够满足生活热水和空调热水出水温度要求,达到最大化利用冷凝热的效果。

One kind of trigeneration watersource （groundsource） heat pump unit with changeover at the water side, whose main feature is that the condenser is divided into first level condenser with sensible heat exchange and second level condenser with heat latent exchange. Through the analysis on technical proposal of the unit and system, as well as the calculation of energy efficiency ratio and performance coefficient of the unit, it is considered that it can make full use of latent heat and sensible heat of condensation heat to carry out cascade heating of domestic hot water separately, and meets the requirements of the outlet temperature of domestic hot water and airconditioning hot water without hightemperature refrigerant, which makes use of condensing heat to the maximum.
