Reduced CFC Refrigerant Emission By a Modified Vapor Compression Refrigeration Cycle
نویسندگان
چکیده
This paper describes a modification of vapor compression cycles with a novel Heat-Mass-Exchange (HME) technique. The HME unit reduces irreversibilities by utilizing the heat generated in the compressor to pump a portion of the refrigerant. It also allows the utilization of low grade heat sources (say, at 100°C) to supply a portion of the required thermodynamic work. Calculations indicate that energy savings of 20 to 30% can be realized, thus making the use non-CFC refrigerants more economically viable. Theoretical and technical considerations of HME-enhanced vapor compression cycle are discussed and two specific examples are provided.

New Refrigeration Cycle To Improve 100-Year-Old Technology
Refrigeration is one of the leading uses of electric power in the United States. The term "refrigeration" refers to air-conditioning for homes, businesses, and industry and the operation of refrigerators, freezers, and heat pumps. The technology most often used in refrigeration, the vapor compression cycle, is 100 years old, inefficient, and environmentally unsound. Since the 1980s, the refrige...

متن کاملDynamical modeling and thermo-economic optimization of a cold room assisted vapor-compression refrigeration cycle
A cold room assisted vapor-compression refrigeration cycle is dynamically modeled in a year and optimized. Total annual cost (TACO) and coefficient of performance (COP) are selected as two objective functions. Both cold room and refrigeration cycle parameters are considered as design variables. Moreover, three working fluids included R22, R134a and R407c are examined. The optimum Pareto front r...

Usually, it is common to use the internal heat exchanger subcooler-superheater after the condenser and before the expansion valve in the compression refrigeration cycles. In this study, the effect of the heat exchanger is evaluated by using recovery heat exchanger after the compressor and before the condenser. To this end, the vapor compression refrigeration cycle with conventional heat exchang...

 liquefied natural gas (LNG) is the most economical way of transporting natural gas (NG) over long distances. Liquefaction of NG by using vapor compression refrigeration system requires high operating and capital cost. Due to lack of systematic design methods for multistage refrigeration cycles, the conventional approaches of determining optimal cycle configuration are mostly based on trial-an...
