HVAC system design for a passive ultra-low energy consumption kindergarten in Beijing

Analyses the energy consumption of the heating and air conditioning system in a passive ultra-low energy consumption kindergarten in Beijing, and presents the heating and air conditioning system design and the efficient heat recovery system. Verifies the rationality of the indoor air distribution by simulation. Through the analysis of toilet ventilation, concludes that toilet ventilation is directly related to the indoor environment and the realization of the goal of ultra-low energy consumption buildings, so the problem of toilet ventilation should be focused on.
