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 کاملExperimental Analysis of Solar Water Heater Using Pulsating Heat Pipe
Solar energy is used for solar water heater in domestic and industrial purpose. Pulsating heat pipe is a fast responding, flexible and high performance thermal conducting device. The CLPHP system described in this study relies on the natural forces of gravity and capillary action and does not require an external power source. The flat plate collector consisted of a 2 mm thick sheet of Aluminum ...
متن کاملHeat pipe-based radiator for low grade geothermal energy conversion in domestic space heating
A severe technical drawback of geothermal heat pumps (GHPs) is the fact that the nominal operating temperature available for domestic space heating is typically in the region of 50°C. This is 25°C to 40°C less than conventional boiler settings used in hydronic central heating applications. As a result, GHPs are not generally ideal for direct replacement of conventional hydronic central heating ...
متن کاملModeling of A Single Turn Pulsating Heat Pipe based on Flow Boiling and Condensation Phenomena
Demand for high-performance cooling systems is one of the most challenging and virtual issues in the industry and Pulsating heat pipes are effective solutions for this concern. In the present study, the best predictor correlations of flow boiling and condensation are taken into account to model a single turn pulsating heat pipe mathematically. These considerations, result in derivation of more ...
متن کاملInvestigation of Entropy Generation Through the Operation of an Unlooped Pulsating Heat Pipe
In the present study, an unlooped pulating heat pipe has been considered with two liquid slugs and three neighboirng vapor plugs.The governing equations such as momentum, energy and mass equations are solved explicitly except the energy equation of liquid slugs.The aim of the present study is to calculate the entropy generation through the performance of a pulsating heat pipe. Additionally, the...
