  • Energy and exergy analysis of Hybrid Ground-Coupled Heat Pumps with hot water supply

    The energy and exergy efficiencies of a Hybrid Ground-Coupled Heat Pump (HGCHP) system with Domestic Hot Water (DHW) supply are analysed based on experimental study. Comparisons between the HGCHP and conventional DHW systems, i.e., Air Source Heat Pump (ASHP), Electric Heater (ElcH) and Gas-Fired Boiler (GasB), are made with respect to the energy and exergy efficiencies. The results show that the ...

WATER SYSTEM CHALLENGES The domestic hot water for the site is produced by two sets of three boilers ...

  • What Are Solar Buildings Technologies?

    Solar buildings technologies use the non-polluting power of the sun to help heat, cool, and power our buildings. Because buildings now use one-third of the energy currently consumed in this country, the potential markets for using solar buildings technologies in place of conventional ones is substantial. Whether you're a home owner, architect, builder, business owner, or industry or utility ...

  • Geothermal Energy... Power from the Depths

    The Earth's crust is a bountiful source of energy—and fossil fuels are only part of the story. Heat or thermal energy is by far the more abundant resource. To put it in perspective, the thermal energy in the uppermost six miles of the Earth's crust amounts to 50,000 times the energy of all oil and gas resources in the world! The word 'geothermal' literally means 'Earth' plus 'heat.' ...

  • Saving waste in the boiler house

    Burner technology has improved greatly in recent years. Older Burners had a series of cams and levers that were calibrated to provide specific amounts of air for a particular rate of firing. Being mechanical items, these wore and sometimes required calibration. They, therefore, had to be regularly serviced and calibrated. Generally, new burners use frequency controlled motors and cams to open air ...
