Rooftop packaged heating, ventilating and air conditioning system utilizing phase change materials

摘要

A cooling system incorporates a return air duct, phase change module, first exhaust duct, second exhaust duct, HVAC module and duct extending from the phase change module to the HVAC module. In a retrofit version, an existing building return of a conventional HVAC system is re-routed to the phase change system and the output of the phase change system is connected to the return side of the existing HVAC system. Standalone cooling systems are also disclosed. In either version, the phase change module receives return air via the return duct and external ambient air via one or more inlets. Mixed return air and external ambient air are forced by a blower/fan to the evaporative cooler, rotating housing containing phase change material, dehumidifier and a subject area to be cooled.
