An evaluation of a rankine cycle driven heat pump

摘要: Abstract This paper discusses a configuration of Rankine cycle engine-driven heat pump, and includes theoretical investigation its performance characteristics. The system employs power cycle, using R-113 as the working fluid, coupled to vapour compression pump R-22. A novel feature concept is use hydraulically connected rolling diaphragm piston-cylinder devices motor, compressor pump. Heating cooling COPs 2.01 1.06 respectively are predicted, making potentially attractive where both heating required.
