==Passive Radiative Cooling Ceramic - A simplified explanation of the abstract==


This abstract first appeared for US patent application 20240044593 titled 'Passive Radiative Cooling Ceramic

==Simplified Explanation==

The patent application describes a radiative cooling apparatus that utilizes a layer of material to reflect incoming electromagnetic radiation from the sun while emitting thermally-generated electromagnetic emission in the mid-infrared wavelengths. This technology, specifically using ceramics, can provide additional cooling effects without the need for electricity consumption, making it beneficial for energy-saving in air conditioning systems of buildings.

* The radiative cooling apparatus includes a layer of material that reflects incoming electromagnetic radiation from the sun.
* The material composition of the layer is designed to reflect at least some wavelengths in the solar spectrum.
* The layer is also configured to emit thermally-generated electromagnetic emission in the mid-infrared wavelengths.
* Ceramics are used in this invention to enhance the cooling effect without requiring electricity consumption.

Potential Applications:

* Energy-efficient cooling systems for buildings and homes.
* Cooling solutions for electronic devices and equipment.
* Thermal management in vehicles and transportation systems.
* Cooling solutions for outdoor spaces and structures.

Problems Solved:

* Reduces the need for electricity consumption in air conditioning systems, leading to energy savings.
* Provides an alternative cooling method that does not contribute to greenhouse gas emissions.
* Offers a sustainable cooling solution for areas with limited access to electricity.

Benefits:

* Energy-saving: Reduces electricity consumption and lowers energy costs.
* Environmentally friendly: Decreases greenhouse gas emissions associated with traditional cooling methods.
* Cost-effective: Provides cooling effects without the need for additional power sources.
* Versatile: Can be applied to various cooling applications in different industries.
* Sustainable: Offers a sustainable cooling solution for areas with limited access to electricity.


==Original Abstract Submitted==

a radiative cooling apparatus including a layer of a material. the layer defines an exterior face. the material has a composition such that the layer is configured to reflect, at the exterior face, at least partly of the incoming electromagnetic radiation of at least some wavelengths in the solar spectrum. the layer is further configured to emit thermally-generated electromagnetic emission of at least some mid-infrared wavelengths out from the exterior face. ceramics provided by embodiments of the invention could produce extra cooling effect without any electricity consumption, creating a prominent benefit to the energy saving of air conditioning systems of buildings.
