Research on the Application of Gas Hydrate in Cool Storage Air Conditioning

Abstract

This paper discusses the cold storage characteristics and the formation mechanism of gas hydrate, studies the selection and substitution of g-h for cool storage air conditioning, the advantages of using g-h formed by multiple refrigerant and water soluble substances as cool storage medium, the effect of additives and the outfield on g-h formation, the characteristics of g-h slurry, the method that accelerates the rapid formation of g-h, the improvement of cold storage device and the requirements of ideal g-h. The flow performance of g-h slurry is the key whether g-h slurry can be applied to air conditioning well, so using CFD sets up the flow model of CO2 g-h slurry in pipeline, whose flow was simulated. Analysis of the pressure drop when the g-h flow in the Vertical bend. Research shows that the characteristics of CO2 g-h slurry is very suitable for the air conditioning system. Finally the paper puts forward some existing problems of g-h cool storage technology to make it practical.
