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 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...
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 کاملTheoretical and Experimental Investigation of a Heat Exchanger Suitable for a Hybrid Ventilation System
A key component in low energy houses is the heat recovery from the ventilation air. Over recent years, the most frequently used ventilation type is the mechanical ventilation with heat recovery. This kind of ventilation results in high heat recovery but does unfortunately consume a considerable amount of electrical energy. Natural or hybrid ventilation has the potential to consume less electric...
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...
