Rooftop Ac Unit With Free Cooling Function
Rooftop systems offer a flexible way to provide treated air for one to eight-story buildings. Many options and configurations are available to satisfy a wide number of applications. Fresh outside air is mixed with return air from the occupied space and then filtered, conditioned, and supplied back into the building. Conditioning involves cooling, dehumidifying, or heating the air for optimal space comfort. Rooftop units can serve a single zone, or an entire building filled with many zones. Some units can be specifically designed for make-up air, where only outside air is treated and sent to the space. Inverter compressors, belt-less EC fans, and energy recovery solutions make rooftop systems an easy-to-maintain, energy-efficient choice for conditioning any space. Electric, hot water, steam, and heat pump heat provide reliable heating for spaces with colder seasons and climates.
