Commercial Building Fresh-Air System Total Heat Recovery

Project Background

A certain 5A-grade office building has a large fresh-air volume during the transitional season, concentrating the load on the HVAC system.

Challenges

Large fresh-air volumes impose heavy cooling/heating load, especially in the shoulder season, keeping energy high.

Solution

Deploy ceiling-mountedEnergy-Recovery Ventilator (ERV) Unit, recovering exhaust energy through the rotary total-heat wheel.

Results

HVAC system energy reduced by 20%, with improved indoor CO₂ levels and enhanced comfort.
