US Patent 11754300 Direct room economizer

A device and a method to provide direct room air cooling. The device is a duct-less economizer that runs independent of existing HVAC systems. The device has its own thermostat setting and is capable of providing significant insulation values when closed. In addition, the method by which the device determines the availability of cool air is improved. This is achieved by using internet weather data, to read outdoor heat indexes, instead of primarily relying on local sensors.
