The Energy Recovery Accessory Module (ERAM) manufactured by CanFab is a complete accessory module mounted to a packaged roof top air conditioning unit. The ERAM includes a centrifugal forward curve supply and exhaust blower, EPAC efficiency motors, air filtration and energy recovery wheel. The energy recovery wheel recovers both latent (moisture) and sensible (temperature) energy. It pre-cools and dehumidifies the outdoor air during the cooling season, while pre-heating and humidifying the outdoor air in the heating season. As the energy transfer matrix rotates between the outdoor and exhaust airstreams, the higher temperature air gives up its sensible energy to the energy transfer matrix. This energy is then transferred to the cooler air stream during the second half of the revolution. As the temperature is captured and released, so is the moisture. The costs of the ERAM and its installation are typically offset by the tonnage reduction of the rooftop unit and associated duct system. In most projects, any first cost premium is paid back within the first year of operation while additional annual energy savings become an annuity.
