Simulation analysis of energy saving effect of ERV on EHP heating energy consumption in a classroom

초록

This study aims to verify energy saving effects of an ERV system on the EHP energy consumption in a classroom. Simulations were carried out by TRNSYS, of which classrooms are equipped with EHP and ERV, which is a typical classroom heating system in Korea. The system performance models are proposed using an optimized method, and they are used for simulations. Results show that the energy saving rates of the ERV on Monday and in the early hours become lower since the classroom remains unheated during the weekend and night time. From the work, it can be concluded that the energy saving rates of the ERV are lower for buildings with lower occupancy rates.
