COOLMIZER

CoolMizer® delivers ventilation air or FREE conditioning by selectively introducing outdoor air into any ducted heating and/or cooling system. Utilizing the system’s blower, air is drawn into the home through an opening controlled by Arzel dampers and distributed through the duct system.

The introduction of either ventilation air or free conditioning air is based upon temperature and humidity parameters for each mode. When the system is serving a heating or cooling call and conditions are favorable, the system holds off mechanical conditioning and opens dampers to the outside. If it receives a second-stage call, it will bring the mechanical system on at its lowest operating mode to “assist” the outside air.

If conditions become unfavorable then the system closes the dampers and goes back to normal mechanical service. Any call that is served by the HVAC equipment must satisfy before the CoolMizer® will interrupt again, so the system will not jump back and forth.
