Integration of variable refrigerant flow system and energy recovery ventilator in different construction climate zones in Vietnam: Case study of a primary school

The heating, ventilation, and air conditioning (HVAC) system consumes a lot of electricity in the building to meet the demand for thermal comfort. The energy recovery ventilator (ERV) has been used in commercial, industrial, and residential buildings to save energy consumption for HVAC systems. In this study, we investigated the efficiency of ERV systems in different construction climate zones in Vietnam and the energy consumption of the sample primary school.
