The proposed model is only based on the thermodynamic laws and the thermodynamic properties of refrigerants. As major design parameters of the analysis, the R134a condensing temperature, the R410A evaporating temperature and the temperature difference in a cascade heat exchanger are applied. To ...

primarily dependent on the guest properties. Studies on pure hydrates of methane8or carbon dioxide9observe a high equilibrium pressure requirement. However, the accidental release of these greenhouse gases from the dense hydrates can negatively impact the environment. The use of thermodynamic promoters ...
