Influence of heat gains on heat recovery in a two-zone-industrial building with several available hot refuse flows

摘要

Several refuse hot air flows with different flow rates and temperature potential are foten generated by an industrial building. A recovery heat exchanger in an industrial building is used to het incoming air for space heating by using the enthalpies of some mixure of these refuse hot-air flows. A proper scenario for use of their enthalpies is essential for efficient management of the energy system. Moreover, there area also in these buildings different heat gains so as from lightance and machines used in production process.
