Enthalpy Recovery System

More ventilation designs are including Energy Recovery Ventilators (ERVs) to improve the system's efficiency. Besides providing controlled ventilation, ERVs are able to filter, humidify, dehumidify, heat, or cool the incoming fresh air. ERVs and HRVs (heat and energy recovery ventilators) were both initially designed and used in Canada and the northern part of the United States, using cold-climate ventilation strategies. ERVs are now beginning to see wider use in the southern climate (southern United States) and during warm and humid summer months in Canada for removing moisture from the incoming air. Therefore, when ventilating in the summer, less moisture brought into the home means less work for the air conditioner, energy savings for the owner, and perhaps improved confort by way of reduced indoor relative humidy.

This study was conducted at the Canadian Centre for Housing Technology to assess the energy performance of an innovative Energy Recovery Ventilator (ERV) in a single-detached house at the Centre, compared to the energy performance of a conventional Heat Recovery Ventilator (HRV) in an identical house next door, to achieve appropriate indoor humidity levels.
