Abstract
The purpose of this field study was to evaluate the performance of heat recovery ventilation (HRV) systems in daily usage. A one-year field measurement campaign was conducted in 25 dwellings with an HRV system among three climate zones in China. The operating pattern of ventilation systems obviously varies from that in developed countries. The occupant’s behavior affects the performance and profitability of HRV systems in households. The operating behavior and economic applicability were analyzed. The heat recovery unit extended the average daily operating duration of mechanical ventilation by 47.2%. The average recovery efficiency of the HRV system was approximately 75% in SC, 65% in C and less than 50% in the HSCW. The efficiency curves of the HRV system under real working conditions were proposed. The applicability of the HRV system must consider not only the climate characteristics but also the use behavior and energy use level of people in different countries. This study is expected to contribute to accurate field data for HRV system evaluation and provide a reference for system design and operational strategies among different climate zones.
