Janus Multilayer for Radiative Cooling and Heating in Double-Side Photonic Thermal System.

ACS Applied Materials and Interfaces, 2021
The temperature of outdoor structures, such as automobiles, buildings, and clothing, can be tuned by designing photonic properties. However, particular challenges arise when considering the temperature of an object itself rather than the enclosure in ...

Collisional-radiative cooling and heating of a gas

Soviet Journal of Quantum Electronics, 1980
An analysis is made of a new effect resulting in cooling or heating of a resonant gas in a radiation field. The effect is due to collisions of resonant atoms with particles of a buffer gas. The magnitude of the effect depends on the ratio of the transport cross sections of the excited and ground states. Qualitative estimates of the degree of cooling or

A self-adaptive film for passive radiative cooling and solar heating regulation

Journal of Materials Chemistry A, 2022
Although passive radiative cooling has received great attention recently because it can minimize the absorption of thermal energy and emits its own thermal energy to the cold outer space, the...

A mathematical study of a combination of night radiative cooling and solar heating system in the subtropical climate

2023 3rd International Conference on Innovative Research in Applied Science, Engineering and Technology (IRASET), 2023
In subtropical climates, the problem of the lack of studies concerning the parametric analysis of radiative cooling technology and its combination with solar heating draws attention.

Improving Heat Dissipation and Temperature Uniformity in Radiative Cooling Coating

Energy Technology, 2020
Heat dissipation has become a key issue in electronic devices with high integration and miniaturization. As an effective way of heat transfer, radiative cooling has aroused a great attention in these devices. However, heat dissipation based on radiative cooling coating is limited by the poor heat spreading and temperature nonuniformity.

Radiative Heating and Cooling Rates in the Middle Atmosphere

Journal of the Atmospheric Sciences, 1986
One of the limitations to the accurate calculation of radiative heating and cooling rates in the stratosphere and mesosphere has been the lack of accurate data on the atmospheric temperature and composition. Data from the LIMS experiment on Nimbus-7 has been extended to the South Pole with the aid of other observations. The data have been used as input

Radiative heating and cooling with spectrally selective surfaces

Applied Optics, 1981
Matter continuously exchanges energy with its surroundings. This exchange can be dominated by radiation, conduction, or convection. In this brief review we discuss how proper design of radiative surface properties can be used for heating and cooling purposes.

Weather‐Adaptive Janus Aerogel Integrated with Phase Change Materials Enables Dual‐Mode Thermal Regulation via Radiative Cooling and Solar Heating

Advanced Functional Materials
Passive radiative cooling offers an electricity‐free strategy to reduce energy consumption. However, most radiative cooling systems focus solely on maximizing cooling performance while neglecting diurnal temperature fluctuations and weather variations ...

Distributions of Atmospheric Radiative Heating and Cooling

1960
Abstract : The time variation of the atmospheric radiation regime is investigated for a selected synoptic situation. Elsasser's graphical method shows the diurnal variation of the upward-directed longwave flux to be in phase with surface temperature changes, but no such change of downward flux was found.

A Dual-Mode Textile for Year-Round Passive Thermal Regulation Combining Radiative Cooling and Solar Heating.

ACS Applied Materials and Interfaces
Maintaining a stable body temperature proves to be critical for human survival and functional capacity. However, conventional textiles exhibit significant limitations in preserving thermoregulatory microenvironments during dynamic climatic variations ...
