Theoretical Study On New Refrigeration Cycle In House-hold Refrigerator

At present, people have confronted two major problems, the shortage of energy and the environmental pollution. It will be the central task of science and technology development in 21st century to find an efficient solution to them. Refrigerating industry, which is closely related to our daily life, is facing severe challenge because some refrigerating fluids used consume Ozone layer and increase green-house effect. Simultaneously how to reduce the quantity consumed by the system of refrigerating is also a forward question for study in thermal-physical engineering.At the basis of analyzing thoroughly the Stirling-Cycle, the thesis puts forward a new refrigerating cycle in house-hold refrigerator, which adopts the two-state, two-component working fluid. Comparing this cycle with the evaporation compression refrigerating cycle, the new cycle has more high coefficient of performance ( COP ) under the same condition. At the same time the working fluid employed doesn't destroy the Ozone layer. The new refrigerating cycle gives a new thinking for refrigerating industry and contribute to the CFCS alternatives.The paper illustrates thoroughly how to establish the model of physics and math, how to chose the working fluid and calculate its thermal-physical quality etc.
