Performance analysis on borehole energy storage system including utilization of solar thermal and photovoltaic energies; Taiyonetsu hikari riyo wo fukumu borehole energy chozo system no kenkyu

Abstract

A permanent borehole energy storage system utilizing solar energy and waste heat from coolers is simulated, to be used as an air conditioning system for super-tall buildings. A 100m-long pipe is buried vertically into the ground, and a heat medium is caused to circulate in the pipe for the exchange of heat with the soil. Thirty borehole units are used, each measuring 9m{times}9m (with the pipe pitch being 3m). Solar cells occupying half of the wall surface facing south and solar collectors installed on the roof supply electric power and heat for cooling and warming. Heat in the ground is transferred mainly by conduction but also is carried by water and gas in movement. So, an analysis is carried out using an equation in which heat and water move at the same time. Because waste heat from cooling and warming systems is accumulated in the ground and none is discharged into the air, big cities will be protected from warming (from developing heat islands). As compared with the conventional boiler-aided air conditioning system, a hybrid borehole system incorporating solar collectors and solar cells will bring about an 80% reduction in CO2 emission and annual energy consumption. 7 refs., 3 figs.,  More>>
