Analysis of heat gain decrease achieved by ventilation heat recovery in solar cooling building: case study

摘要

The aim of this work is to present the improvement of the operation of the solar building cooling system by using ventilation with heat recovery, and thus reducing required cooling power of air conditioning system. The heat recovery system is divided into zones with counter-flow plate heat exchangers (laboratories, required system tightness, no air recirculation) and counter-flow spiral heat exchangers (office and conference rooms). The analysis was carried out for the real indoor conditions, measured on the site and climatic data of a typical meteorological year.
