Carrier is expanding its line of WeatherExpert packaged rooftop units with the new high outdoor air system, a light commercial rooftop unit capable of conditioning up to 100% outdoor air. The WeatherExpert high outdoor air system can operate with up to 100% outdoor air for ventilation or make-up air or building ventilation. They can pair with space air conditioning and heating systems, such as Carrier VRF, water source heat pumps or rooftop units, to provide a complete HVAC solution for schools, hotels or office buildings.
When a stand-alone solution is preferred, the WeatherExpert high outdoor air system can condition up to 50% outdoor air to provide heating, air conditioning, dehumidification and ventilation for retail spaces, gymnasiums, restaurants and other light commercial buildings.
Commenting on the development, Mark Rabbia, Director of Light Commercial Product Management, Carrier, informed, “The demand for HVAC systems that can introduce high levels of outdoor air in occupied spaces has significantly increased in the last two years. It’s not enough to just replace indoor air with fresh outdoor air more quickly, but rather to do so in a cost-effective and energy-efficient manner. High outdoor air applications require specific features and options to deliver solid, cost-effective performance under a wide range of operating conditions. These units deliver on all those fronts.”
The WeatherExpert high outdoor air systems are part of the WeatherExpert 48/50LC ultra high-efficiency rooftop unit family and achieve up to 13.1 EER full-load and 20.8 IEER part-load cooling efficiencies.
