Heat 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 کاملHeat 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 کاملAssessment and Deployment of Ground Source Heat Pump for Air Pollution Reduction in Tehran, Iran
The use of renewable energies, especially in metropolises has led to a reduction in environmental pollution and greater access to clean, renewable and sustainable energy. This paper evaluates the effectiveness of a national plan adopted by the Tehran city council for reducing air pollutions. This plan is designed to increase the share of renewable energies in residential buildings. This study a...
متن کاملResearch on Ground Source Heat Pump Design
One of world’s largest uses of energy is the heating and cooling of buildings. Ground Source Heat Pumps (GSHP) provide a more energy efficient way to meet building energy needs than conventional alternatives. At a relatively shallow depth, the ground temperature is nearly constant year round providing a reliable heat source or sink for the operation of a heat pump. The design of such systems is...
متن کاملOptimal Design for a Hybrid Ground-Source Heat Pump
Although the advantages of ground-source heat pumps over their conventional alternatives make these systems a very attractive choice for air conditioning, not only for residential buildings but increasingly also for institutional and commercial buildings, a significant barrier to wider application of this technology is a high first cost. When used in cooling-dominated buildings, ground-source h...
