Improvement possibilities of vapour compression refrigerating cycles by utilization of expansion engines.
Author(s) : MARKOSKI M.
Summary
The paper presents three possible ways of utilization of the expansion work in the vapour compression cycle. The first one is to replace the expansion valve with an expansion engine. The second one is the power recovery to the compressor in a non-conventional vapour compression cycle with isobaric-non-isothermal heat absorption. The third one is the utilization of expansion work for liquid recirculation through the flooded evaporator. Based on the above-mentioned analysis, guidelines for the use of expansion work can easily be derived.
