Heat Sponge: A Concept for Mass-Efficient Heat Storage [PDF]

open access: yes46th AIAA Aerospace Sciences Meeting and Exhibit, 2008
The heat sponge is a device for mass-efficient storage of heat. It was developed to be incorporated in the substructure of a re-entry vehicle to reduce thermal- protection-system requirements. The heat sponge consists of a liquid/vapor mixture contained within a number of miniature pressure vessels that can be embedded within a variety of different ...

Latent heat storage integration into heat pump based heating systems for energy-efficient load shifting

open access: yesEnergy Conversion and Management, 2021
Abstract Integrating latent heat thermal energy storage (LHTES) units into building heating systems has been increasingly investigated as a heat load management technology. A conventional LHTES integration method for heat pump based heating systems is to connect the heat pump’s condenser for charging the LHTES unit.

A Study on Heat Storage and Dissipation Efficiency at Permeable Road Pavements [PDF]

open access: yesMaterials, 2021
The main contributing factor of the urban heat island (UHI) effect is caused by daytime heating. Traditional pavements in cities aggravate the UHI effect due to their heat storage and volumetric heat capacity. In order to alleviate UHI, this study aims to understand the heating and dissipating process of different types of permeable road pavements. The
