基于室外气象参数的排风热回收装置能耗特性

摘要

提出一种基于室外气象参数的排风热回收性能分析方法.在计算热回收装置的节能量时考虑了装置本身的运行能耗,计算得到不同热回收方式下该地区可使用热回收装置的最低比焓或温度.以上海地区某图书馆为例,逐时计算了热回收装置的回收量和电耗,经比较获得了全年不同条件下相对节能的热回收方式和工作模式,为系统的优化设计提供计算参考.%Presents a related analysing method. Considers its energy consumption in calculating the energy savings of the heat recovery unit, and obtains the local minimum enthalpy or temperature under different recycling modes. Taking a library in Shanghai for example, based on typical all-year meteorological parameters, calculates the hourly energy recovery amount and power consumption and obtains the optimal recycling modes and working modes for the heat recovery units through comparison, providing calculation reference for optimal design of HVAC systems.
