Given the critical importance of energy and cost savings, the application of engineering and management principles
has the potential to reshape the design of modern heat pump systems. Microchannel heat exchangers, ejectors,
and injection-compressors are some of the latest more interesting developments in heat pump components
that boost up the energy performance with respect to the basic heat pump cycle. In this article an overview of the
current development trends for heat pump components is discussed and the performance improvement using
novel, and sometimes complex and bizarre, heat pump cycles is summarized.
