Abstract— Ground source heat pump systems offer economical alternatives of providing thermal comfort for use in various industrial, commercial and residential air conditioning applications. As the cost of energy continues to rise, it becomes imperative to save energy and improve overall energy efficiency by searching renewable sources of energy. In this light, the ground source heat pump becomes a key component in an air conditioning system with great potential for energy saving by use of renewable energy available from beneath the earth surface. Improving ground source heat pump performance, reliability, and its environmental impact has been an ongoing concern. Recent progresses in ground source heat pump systems have centered upon advanced cycle designs for both heat- and work-actuated systems, improved cycle components (including choice of working fluid), and exploiting utilization in a wider range of applications in different climatic conditions. For the ground source heat pump to be an economical in operation continuous efforts need to be devoted to improving its performance and reliability.
Keywords—Ground source heat pump, geothermal energy, air conditioning, Energy efficiency.
I. INTRODUCTION
The ground source heat pump (GSHP) has evolved to become a mature air cooling technology over the past two decades. However, it is not applied as widely as it should or could be. Initial costs, system design and integration remain to be challenging problems, since few major vendors of refrigeration systems offer large-scale heat pumps. Efficient use of geothermal energy in such energy-intensive operations as district cooling/ heating and drying is crucial to the reduction of net energy consumption and hence emissions of greenhouse gases. With the eventual acceptance of a carbon/energy tax around the world energy, energy conservation will become a key concern in many industrial operations. With raising cost of fuel and global warming at the forefront of world attention, the interest in ground source heat pump as a means of geothermal energy use (Fig. 1) appears to have been resurrected. Geothermal heat pumps offer one of the most practicable solutions to the greenhouse effect by use of geothermal renewable heat or cold energy.
