BACKGROUND Ground source heat pumps is a building energy conservation technique. The underground buried pipe heat exchanging system of a ground source heat pump (GSHP) is the basis for the normal operation of an entire heat pump system. METHODS Computational-fluid-dynamics (CFD) numerical simulation software, ANSYS-FLUENT17.0 have been performed the calculations under the working conditions o...

Abstract The rapid economic growth of Southeast Asian countries is followed by accelerated population and energy demand growth. On the other hand, region still relies heavily on fossil fuels as primary source electricity. As a result, there growing concern about future regional sustainability. Space cooling has become one fastest-growing sectors. Introducing new space technology capable providi...

Abstract Due to the lack of suitable evaluation systems for heating, ventilation, air-conditioning (HVAC) with ground source heat pump (GSHP) and energy storage (ES) technologies, it is difficult design a building HVAC system achieve optimized regard investment cost, saving environmental protection. This study on developing fuzzy by including GSHP ES comprehensively determined weights into an s...

Utilization of the renewable resources in district heating systems can reduce use fossil fuels, operating costs and protect environment. In this study, an integrated hybrid system consisting concentrating photovoltaic/thermal collectors (PV/T), geothermal (GSHP) absorption (AHP) heat pumps is considered for heating. The thermodynamic performance at various conditions explored through detailed s...

The earth’s surface acts as a huge solar collector, absorbing radiation from the sun. In the UK, the ground maintains a constant temperature of 11-13oC several metres below the surface all the year around.1 Among many other alternative energy resources and new potential technologies, the ground source heat pumps (GSHPs) are receiving increasing interest because of their potential to reduce prim...

The PV/T-GSHP heating control system is proposed to address the energy consumption problem of building in northern China. By using TRNSYS establish an automatic model, heat pump start/stop, water supply temperature on load side tank, and high return can achieve purpose being saving, providing stable heating, heating. results show that has annual fluctuation range 0.01~0.17 kW period for a typic...

The data reported in this article presents actual installation costs and performance data for a selection of residential Ground Source Heat Pump (GSHP) systems in Melbourne, Australia. The installation cost data includes five main cost components: ground loop installation, head pipe installation, heat pump, mechanical room installation, and fittings. The performance data presented here includes...

Ejector-based refrigeration systems can make direct use of many forms thermal energy, such as solar thermal, waste heat, biogas, or natural gas. The present paper describes the estimation coefficient performance (COP) a binary fluid ejector ground source heat pump (BFE GSHP) cooling system. A method for selection was defined based on favorable thermo-physical properties working fluids. short li...
