The Effects of Exterior Glazing on Human Thermal Comfort in Office Buildings

open access: yesEnergies
As a major component of the building envelope, the energy-saving design of exterior windows is key to energy savings in office buildings. The conventional design of exterior windows mainly focused on their impact on heating and cooling energy but ignored

Hourly calculation method of building energy demand for space heating and cooling based on steady-state heat balance equations

open access: yesJournal of Civil Engineering and Management, 2012
Correct evaluation of solar heat gains through fenestration into the rooms has a great impact on energy demand calculations for buildings. This article presents an hourly energy demand calculation method for heating and cooling, which considers the fact ...

Temperature-independent thermal radiation [PDF]

open access: yesProceedings of the National Academy of Sciences, 2019
Significance Conventional wisdom states that the hotter an object is, the brighter it glows. This is the case for thermal light at any wavelength and enables applications such as infrared imaging and noncontact thermometry. We demonstrate a coating that emits the same amount of thermal radiation irrespective of temperature, within a ...

Adiabatic Thermal Radiation Pumps for Thermal Photonics [PDF]

open access: yesPhysical Review Letters, 2019
We control the direction and magnitude of thermal radiation, between two bodies at equal temperature (in thermal equilibrium), by invoking the concept of adiabatic pumping. Specifically, within a resonant near-field electromagnetic heat transfer framework, we utilize an {\it instantaneous} scattering matrix approach to unveil the critical role of wave ...

Physics with nonperturbative quantum gravity: radiation from a quantum black hole [PDF]

open access: yes, 1996
We study quantum gravitational effects on black hole radiation, using loop quantum gravity. Bekenstein and Mukhanov have recently considered the modifications caused by quantum gravity on Hawking's thermal black-hole radiation.

On the Emissivity and Absorptivity of Plastic Shading Nets under Natural Conditions

open access: yesAdvances in Mechanical Engineering, 2015
It is impossible to directly measure the thermal radiative properties of shading nets because of the net's perforated structure and the difficulty to distinguish the transmitted, reflected, and emitted radiation on the net surface. In addition, Kirchhoff'

Numerical Simulations on the Protection of the Molten Salt Thermal Tube under Cloud Occlusion

open access: yesZhongguo dianli, 2020
Based on the single tube model of the receiver, the temperature drop characteristics of the endothermic tube such as the heat flux, molten salt flow rate and surface convection heat transfer coefficient were studied through numerical simulations on the ...
