Radiative Cooling Devices and Air Conditioning Systems with Vertical Orientation

This invention is for radiative cooling devices and air conditioning (AC) systems for installation in vertical environments such as windows and walls. This new engineering features coatings with angular emissivity designed to optimize energy efficiency by targeting the zenith and avoiding thermal radiation output from nearby structures, while also shielding radiation from the Earth.

Background: 
Radiative cooling systems typically have a horizontal orientation with unobstructed access to maximize exposure to the sky above. Contrarily, vertical systems struggle to achieve the same access with challenges stemming from structural interference and cooling limitations from surrounding radiation in thicker sections of the atmosphere and in larger spaces. This new vertically oriented device combines several innovative coatings, mirrors, and thermal emitters to improve cooling efficiency and reduce structural radiation interference.

Applications: 

• Vertically oriented radiative cooling system
• Vertically oriented air conditioning system

Advantages: 

• Energy-efficient 
• Versatile applications in residential and commercial establishments
• Direction of thermal radiation towards zenith
• Mirror reflection to improve cooling efforts
• Allows for larger spaces to be cooled more efficiently
• Design reduces structural radiation interference
