In this paper, the possibility of using hydrate-salts in solar pond as phasechange heat storage material is discussed, due to its formation of gradient layer for both sensible and latent heat storage for seasonal heat storage with only 3-5 cycles year round.
The result showed that this product has good heat storage stability,water separation characteristics,detergency,synergism with detergents such as sulfurized calcium alkyl phenate- It can be used to marine cylinder oil and medium & premium diesel oils. TBN40 and TBN70 marine cylinder oils formulated with it have past Bolnes-3 DNL bench test
Based on the compassion and analysis of three kinds of heating storage of active solar heating system this paper makes a conclusion that there is no a ideal heating storage way to make active solar heating system meeting the requirements of people for heating confortableness without aid of another energy.
The paraffin wax (with melting temperature of 29°C, crystallizing temperature of 26°C and latent heat of 142 J/g) served as latent heat storage material and the silica as supporting material, which prevented the leakage of the melted paraffin wax.
The upper oceanic heat budget in the South China Sea (SCS) is studied on the basis of ocean surface heat flux, upper sea heat storage and horizontal oceanic heat transport calculated from Comprehensive Ocean and Atmosphere Data Set.
The variation of upper oceanic heat storage of the SCS is tightly connected with the oceanic heat transport as well as the vertical movement in the SCS and so on.
The water used as heat transfer fluid (HTF) to transfer heat from the solar collector to the storage tank also acts as sensible heat storage material.
Performance of underground heat storage system in a double-film-covered greenhouse
