Advantages and benefits of using Model YDHA, packaged ventilation air, cooling/heating/dehumidification system. (2:32)



Description
Model YDHA space conditioning unit provides superior control of high volumes of outside air in a packaged DX system design. The model’s feature set allows it to properly condition upward to 50% outside air while maintaining space temperature and humidity conditions. The unit’s blower system incorporates superior energy efficient blower design with variable speed control to balance and control the airflow as needed. The DX system maximizes efficiency with the use of digital scroll technology, ECM condenser fans and optimized coil designs. The DX system exceeds ASHRAE standard 90.1 requirements. Model YDHA includes the Tcore3 condensing heat technology. Tcore3 condensing gas heating system maintains greater than 90% efficiency throughout the modulated control range. The system features state of the art stand alone control system that further maximizes energy use while maintaining space temperature condition.
