  • Zoo-technical application of Ground Source Heat Pumps: a pilot case study

    Ground Source Heat Pumps are energy-efficient HVAC systems usually adopted in residential and commercial buildings. However the control of the thermal environment is required not only in spaces occupied by people, but also in intensive breeding farms, in order to maintain healthy conditions and to increase productivity. In the Italian livestock breedings, heating is usually provided by means of ...

  • Exergetic and sustainability performance assessment of geothermal (ground source) ejector heat pumps

    Although ejectors have been used in cooling/refrigeration and Heat Pumps (HP) applications for a long time, utilisation of Geothermal Ejector Heat Pump (GEHP) with Ground–Heat Exchanger (GHE) is a new idea, which has recently appeared in the literature. In this study, we model a GEHP system with a GHE in terms of exergetic aspects and apply our model to this system in the heating mode. The system ...

  • What’s geothermal again?

    Some green energy sources seem to have charisma; others struggle for public attention with little success. Solar energy is an “it” technology, as evidenced once again by the tremendous participation in the annual Solar Power International conference in Anaheim, California this week (Oct. 27-29). Twice as many companies (945) are displaying their wares in the Expo Hall this year, despite the still ...

  • China and US cooperate on building efficiency

  • Using electricity to save the planet

    When it comes to energy efficiency, it used to be the big guys that mattered. Policymakers and market leaders focused on manufacturers, refiners and others that gobbled up lots of kilowatt hours.It’s not surprising. Manufacturers create bang for the buck. Better motors, refrigeration or combined heat and power can lead to six-digit dollar savings — far more impressive than the $10 per month an ...

  • Heat Pumps – FAQs

    1. What is a Heat Pump? To put it simply; ground source heat pumps and geothermal heat pumps produce high grade heat from low grade heat which is found in the earth and our atmosphere.2. How does a Heat Pump Work?Heat pumps work in exactly the same way as air conditioners or refrigerators, but in reverse! Heat pumps capture latent energy which is stored in sources such as air, water and earth. ...


  • Ground Source Heat Pumps

    In many buildings Ground Source Heat Pumps (GSHPs) provide an efficient solution for heating and cooling. Using low temperature latent heat which exists naturally below ground, GSHPs provide solutions by harvesting and transferring this energy for the benefit of the built environment. It is important to understand the feasibility of GSHP prior to designing a system. This guidance note has been ...

  • Geothermal Energy Technologies

    Technology Overview   Nowhere is the raw power of geothermal resources more evident than at the Old Faithful geyser at Yellowstone National Park. (Joel Renner)  Geothermal energy is natural heat from the Earth's interior where temperatures reach greater than 7000°F. The heat is brought to the surface as steam or hot water—created when water flows through heated, permeable ...
