Alternative technologies for refrigeration and air conditioning applications [thesis]

Don Carlyle Gauger
A study was conducted to assess refrigeration technologies which are alternatives to vapor compression refrigeration for use in five application categories: domestic air conditioning, commercial air conditioning, mobile air conditioning, domestic refrigeration, and commercial refrigeration. A fundamental criterion for the selection of the alternative refrigeration technologies to be assessed was that they be environmentally safe. The study was conducted in three phases: a survey of U.S.

The U.S. patent survey was conducted from 1918 to the present. A method was developed for classifying refrigeration technologies found during the survey. Thermodynamic models were developed for the alternative refrigeration cycles. A computer program was written using these thermodynamic models to conduct a parametric study of the cycle efficiency of the alternative refrigeration technologies. A method for assessing and comparing the refrigeration technologies was developed. Six technical assessment criteria were identified: state-of-the-art, complexity, size and weight, maintenance, useful life, and efficiency. It was concluded that the most promising alternative refrigeration technologies to vapor compression were absorption and solid sorption. From environmental and economic standpoints,
