Heat transfer analysis of underground U-type heat exchanger of ground source heat pump system
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...
متن کاملHeat exchanger technology and applications: ground source heat pump system for buildings heating and cooling
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...
متن کاملSimulation of a Domestic Ground Source Heat Pump System Using a Transient Numerical Borsehole Heat Exchanger Model
Common approaches to the simulation of Borehole Heat Exchangers (BHEs) assume heat transfer in circulating fluid and grout to be in a quasi-steady state and ignore fluctuations in fluid temperature due to transport of the fluid around the loop. However, in domestic ground source heat pump systems, the heat pump and circulating pumps switch on and off during a given hour; therefore the effect of...
متن کاملDevelopment of a Ground Source Heat Pump System with Ground Heat Exchanger Utilizing the Cast-in-place Concrete Pile Foundations of Buildings
Ground-source heat pump (GSHP) systems can achieve a higher coefficient of performance than conventional airsource heat pump (ASHP) systems because the ground, which functions as the heat source or sink, is at a higher temperature in winter and lower in summer than the air temperature (Kavanaugh 1992; Kavanaugh et al 1997). In addition, there will likely be some mitigation against the effects o...
متن کاملInfluence of Ground Heat Exchanger Modelling on the Predicted Efficiency of the Heat Pump System
This paper presents simulations of the integral coefficients of performance of a heat pump system coupled with a vertical ground heat exchanger (GHE). The GHE is simulated using different assumptions concerning the heat transfer in the ground, heat exchange between the ground and the brine and vertical variation of the brine temperature. The differences in the predicted performance coefficients...
