US Patent No. 10,473,348 Plain Language Overview

The patent relates to eliminating air stratification via ductless devices. Specifically, the patent describes methods and systems of increasing air turnover in a building to accomplish this goal.
The patent recites at least the following features:
• Based on how much air needs to be managed and where the current HVAC systems are located, the patent describes figuring out how many “ductless devices” are needed to eliminate air stratification and where to put these devices within a building.
• Two or more “ductless devices” with three exit ports (one front, two side) are used to increase air turnover within the building.
• Devices output air at a distance of 200 feet or more from the front port horizontally; the distance air is output from the side ports is less than 200 feet.
• Devices are placed so that air from one of the devices joins air from another device.
• Devices have fans which rotate in opposite directions.
• Air coming out of the devices is mixed with the building’s air so that air turnover increases.
• A sensor detects the temperature of the building and adjusts the volume of air drawn into the device based on the temperature.
