“…Further, the COP can be improved by approximately 25% when the mass percentage of R134a is 50% of the mixture R22/R134. Lee et al [32] found that R32/R152a mixture can be a substitute for R22. Park et al [33][34][35] measured the thermodynamic performance of R431A, R432A, R433A, and R22 under the same conditions, and demonstrated that both R432A and R433A are good alternatives to R22.…”

“…Both of them have been regarded as the potential candidates of the new generation refrigerants [1,2,35,36]. Besides, the normal boiling point of R152a is quite closed to that of R1234ze (E), which is beneficial to form to be azeotropic or near azeotropic mixtures.…”

“…Additionally the ranking of the four heat pump types from high to low according to the exergy destruction rates of them is as follows; air to air (2.93 kW), air to water (2.84 kW), water to air (2.64 kW) and water to water (2.55 kW). It is understood that exergy efficiency of water to air and air to air heat pump systems are higher than the exergy efficiency of water to water and air to water type heat pumps.…”

Owing to the eye‐catching pros of high energy and environmental performances, numerous ground‐source heat pump (GSHP) systems have been employed in domestic and industrial buildings throughout the world. One of the proved renewable energy technologies is the GSHPs which is able to fulfill the gap between cooling and heating. The main contribution of this article is to present a fully description and critical review of the GSHP systems along with their current developments. At first, the energy efficiency and working standard of a heat pump are introduced. Furthermore, an expansive description of the GSHPs and its advances, and a fully explanation of the ground‐couplet (GCHP) heat pumps, ground‐water (GWHP), and surface water (SWHP) are provided. The mainly representative ground thermal response examination approaches and simulation for the vertical ground heat exchangers presently existing are reviewed counting the heat transfer progressions inside and outside the holes. Similarly, various info regarding a different GWHP by a heat exchanger with different structures, and the opportunity to gain the enhanced energy efficiency with joint cooling and heating using GCHP are explained. The numerous hybrid GCHP systems for heating or cooling‐dominated constructions are appropriately illustrated. It can be deduced that the GSHP technology can be employed both in hot and cold weather areas and the potential of energy saving is noteworthy. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1241–1265, 2018
