热回收冷水机利用冷水机回收的热量为建筑物提供热水，这既高效又经济。然而，并不是每个中央设备都适用于热回收冷却器，因为需要同时加热热水和冷冻水负荷。以往关于热回收式制冷机应用的大多数研究都集中在带有热回收式制冷机的公用设施的优化设计技术上。关于如何在不同的操作条件下高效运行热回收冷却系统，操作员几乎没有指导方针。 影响因素包括电力需求费用和费率结构、供暖热水供应温度、供暖热水回路delta-T退化、冷冻水回路delta-T退化，以及电厂中其他变速驱动冷水机组的性能，这些都会影响运行效率。本文介绍了德克萨斯州中部一个大型地区工厂热回收制冷机应用的几种调试措施。楼宇自动化系统（BAS）的现场测量数据用于开发回归模型，以评估每项测量的节约潜力。 与无热回收的基准冷水机相比，当前的运行策略每年节省270375美元，但在当前公用事业价格下，拟议的控制策略将节省389182美元/年，比当前的控制策略多节省43.9%。虽然这些节省是基于一个案例研究项目，但该方法和控制策略可用于优化其他热回收制冷机应用。引文:2018年冬季会议，伊利诺伊州芝加哥，技术论文

A heat recovery chiller provides heating hot water tobuildings by using recovered heat from the chiller, which is efficientand cost-effective. However, not every central plant is anappropriate application for heat recovery chillers becausecoincident heating hot-water and chilled-water loads arerequired. Most previous studies on applications of heat recoverychillers have focused on techniques for optimal design ofa utility plant with heat recovery chillers. There are very fewguidelines for operators on how to run a heat recovery chillersystem efficiently at different operating conditions. Factorsinclude electricity demand charges and rate structure, heatinghot-water supply temperature, heating hot-water loop delta-Tdegeneration, chilled-water loop delta-T degeneration, andthe performance of other variable-speed drive chillers in theplant, which all affect operational efficiency. This paper presentsseveral commissioning measures for a heat recoverychiller application at a large district plant in central Texas. Theon-site measured data from the building automation system(BAS) is used to develop a regression model to evaluate thesavings potential for each measure. The current operatingstrategy saves $270,375/year compared to a baseline chillerwithout heat recovery, but the proposed control strategieswould improve the savings to $389,182/year at current utilityprices, or 43.9% more savings than the current control strategy.Although these savings are based on a case-study project,the methodology and control strategies can be applied to optimizeother heat recovery chiller applications.
