eothermal heat pumps (GSHPs) or direct expansion (DX) ground source heat pumps are a highly efficient renewable energy
technology which uses the earth, groundwater or surface water as a heat source when operating in heating mode or as
a heat sink when operating in a cooling mode. It is receiving increasing interest because of its potential to reduce primary
energy consumption and thus reduce emissions of the greenhouse gases (GHGs). The main concept of this technology is that it
utilises the lower temperature of the ground (approximately <32°C), which remains relatively stable throughout the year, to provide
space heating, cooling and domestic hot water inside the building area. The main goal of this study is to stimulate the uptake of
the GSHPs. Recent attempts to stimulate alternative energy sources for heating and cooling of buildings has emphasised the
utilisation of the ambient energy from ground source and other renewable energy sources. The purpose of this study, however, is
to examine the means of reduction of energy consumption in buildings, identify GSHPs as an environmental friendly technology
able to provide efficient utilisation of energy in the buildings sector, promote using GSHPs applications as an optimum means
of heating and cooling, and to present typical applications and recent advances of the DX GSHPs. The study highlighted the
potential energy saving that could be achieved through the use of ground energy sources. It also focuses on the optimisation
and improvement of the operation conditions of the heat cycle and performance of the DX GSHP. It is concluded that the direct
expansion of the GSHP, combined with the ground heat exchanger in foundation piles and the seasonal thermal energy storage
from solar thermal collectors, is extendable to more comprehensive applications.
