Return Air Plenum Box
Product Introduction

Product Performance
- Return and exhaust air outlets are designed for air return. When the indoor cooling load is fixed, the volume of cold air supplied to the room remains constant.
- Compared with fresh outdoor air, indoor circulated air has a lower temperature in summer. Part of this indoor air is returned to the air handling unit via return air ducts and mixed with a small amount of fresh air to produce conditioned cold air for indoor supply.
- This method achieves significant energy savings compared with systems that use 100% fresh air for cooling.
