Development and analysis of a high-temperature heat pump for steam generation using hydrocarbons as refrigerants.
Number: 0124
Author(s) : HASSAN A. H., PAYÁ J., NAVARRO-PERIS E.
Summary
The current paper investigates the thermodynamic feasibility of three different high-temperature heat pump (HTHP) configurations to generate steam at 150 ⁰C. The first and second configurations use the HTHP to generate saturated and superheated steam, respectively, while the final one is to couple the HTHP with a steam compressor. Various hydrocarbons with high critical temperatures were compared. The second configuration shows the most promising results compared with others. Under source temperature of 65 ⁰C and condensation temperature of 120 ⁰C, this configuration shows coefficient of performance (COP) values of 3.55, 3.50, 3.44, 3.14, and 3.03 for Propanone, n-Pentane, 1-Pentene, n-Butane, and Butene, respectively.
