针对目前供冷供暖供生活热水系统的热水温度达不到60℃,且系统能效较低的现状,提出了该空调系统作为解决方案,根据能源梯级利用原则,在不提高冷凝温度的同时回收了部分潜热及全部显热。介绍了热回收系统蓄热阶段、用热阶段和不用热阶段的工作模式。结合某工程实例,介绍了机组的详细参数以及热回收热水系统的设计计算,供冷期的运行分析结果表明,在不同负荷率工况下,热回收量均大于生活热水用热量,即在供冷期,可以免费提供生活热水。
In view of the fact that the temperature of hot water in domestic hot water supply system is less than 60 ℃ and the energy efficiency of the system is low, the air conditioning system is proposed as a solution. According to the energy cascade utilization principle, without increasing the condensing temperature Recycled part of the latent heat and all the sensible heat. This paper introduces the heat recovery system heat storage phase, with hot stage and not hot stage mode of operation. Combined with an engineering example, the detailed parameters of the unit and the design and calculation of the heat recovery hot water system are introduced. The analysis of operation during the cooling period shows that under different load rates, the heat recovery is greater than that of domestic hot water, In the cooling period, you can provide free hot water.
