Description
Summary:The temperature frequency method is used to analyze the energy savings of the wall-type energy recovery fresh air ventilator in three different typical regions, namely Guangzhou, with a tropical monsoon climate; the sub-temperate Wuhan; and Beijing, with a temperate monsoon climate, throughout the year. The influence of different temperature efficiencies and resistance levels of the energy recovery ventilator (ERV) on annual energy efficiency is also analyzed. The control temperature of the auxiliary heating device used in the winter is discussed, and the indoor temperature variation trend in the inter-wall-type energy recovery fresh air ventilator operating 24 h on four typical days of the year under different control modes is analyzed in the tropical monsoon climate of Guangzhou. The conclusions obtained can provide a reference for the application and selection of inter-wall-type energy recovery fresh air ventilators.
