The XChanger damper system is a forced heating and cooling air management system that brings its greatest benefits to facilities with high ceilings. XChanger works with all HVAC systems that use forced air (warm and cold) to condition the space. It can stratify or de-stratify a space depending on season and building demand greatly enhancing the existing HVAC equipment’s efficiency. Up to 30% improvements in air conditioning and heating have been demonstrated. The XChanger uses conventional HVAC construction materials and easily integrates with existing HVAC rooftop units (RTUs) and building controls. XChanger targets from 5 ton up to 20-ton single systems (or zones).
The costs vary per application, depending on existing HVAC infrastructure and building requirements. Significant annual utility savings + IRS Section 179 Bonus Depreciation + utility rebates + low interest financing make most applications in the 1-year payback range or less. We would be glad to evaluate your facility and give you a cost and savings estimate.
Due to the enhanced efficiency and lower peak demand periods, an XChanger installation during a retrofit can save significant capital costs on RTU count and HVAC total tonnage required. The number and size of RTU’s can be reduced – effectively paying for the XChanger upgrades.
Humidity levels are typically measured at occupant level and because the XChanger system focuses on increasing comfort and temperature control at that level, humidity in that space is also controlled more effectively. By stratifying the air in cooling mode and returning at the mid-line, the air temperature above the mid-line will be elevated. As the temperature of the volume of air above the mid-line rises, by definition the humidity level at the ceiling decreases. If you raise the temperature of a constant volume of air at constant humidity – making that air warmer – by definition you are lowering the moisture content of that air. As the air temperature goes up high in a space, two things occur. The humidity level of the air goes down and the materials in contact with the air heat up. The warming of the materials prevents condensation (sweating). The lack of liquid water prevents the growth of mold.
Our experience at Holmatro in the hot and humid Maryland summer is that the increased efficiency of the system, the stratification of the air, and the focus on the occupied zone allowed us to raise the thermostat setpoint from 70 to 72 or 72 to 74. The occupants were more comfortable at the desired internal humidity setting, resulting in significantly less energy consumption.
XChanger uses HVAC engineering partners for evaluation of your facility pre- and post-installation utilizing Trace software to model the improvements. Data such as past utility bills, ambient site conditions, existing HVAC equipment, etc. will support an informed assessment.
