摘 要: 通过分析评价各类热回收空气机组的性能及热回收效率,拟选定最优类型的热回收空气机组,计算出其回收的能量,按空调系统综合能效比将回收的能量折合成节约的运行电能,从而计算采用空气热回收机组在运行中节省的运行费用。将热回收空气处理机组与常规的空气处理机组进行比较,综合分析其技术经济性,最终得出该项目采用热回收空气处理机组的可行性,为业主是否采用热回收装置的决策提供技术参考。
Abstract: The optimal type of heat recovery unit is to be selected to calculate the energy of its recovery and to calculate the operating expenses of the air heat recovery unit in operation, through analysis and evaluation of the performance of various heat recovery air units and their heat recovery efficiency. By comparing the heat recovery air handling unit with the conventional air handling unit, the technology and economy of the unit were analyzed, the feasibility of using the heat recovery decisions is obtained, and the owners is provided of the technical reference abort the decision whether to adopt the heat recovery device.
