Thermodynamic analysis and assessment of space heating with ground–source heat pump for sustainable future
In this paper, the thermodynamic modelling of exergy loss, exergy efficiency, exergy destruction rate, environmental destruction coefficient, improvement potential, exergy destruction factor, relative irreversibility, productivity lack and exergetic factor of ground source heat pump (GSHP) system are investigated. The results show that these exergy indexes should be used integratively. Compressor ...

Heating Electrification: Policies to Drive Ground-Source Heat Pump Adoption
Executive Summary Ground-source heat pumps (GSHPs) are typically the most efficient form of heating and cooling for buildings. For every unit of electricity a GSHP system consumes, it produces roughly 3-4 units of equivalent heat (or cooling), thanks to the solar energy naturally stored underground. Because of these efficiencies, GSHPs can provide significant cost savings in the effort to ...

Rational use and management of geothermal energy resources
This article identifies and explains several attributes of geothermal energy. High exergetic efficiency due to a close temperature tie between geothermal energy and district heating and cooling was noted. Parameters governing the rational use and management of geothermal energy systems with special emphasis on integrated-cascaded district energy systems were formulated and explained with two case ...

Ground Source Heat Pumps Rudges Hill Case Study
Rudges Hill is a converted farm house in rural Oxfordshire undergoing renovation and extension. The owners were keen to reduce the future running costs of heating the house, producing hot water and heating the outdoor pool. Isoenergy installed a 34kW CTC ground source heat pump system with energy collected from 2,400 meters of horizontal collector array in a nearby field. The system is supported ...

Impacts of Shallow Geothermal Energy on Groundwater Quality
The use of shallow geothermal energy (SGE) systems to acclimatize buildings has increased exponentially in the Netherlands and worldwide. In certain areas, SGE systems are constructed in aquifers also used for drinking water supply raising the question of potential groundwater quality impact. Impacts of Shallow Geothermal Energy on Groundwater Quality provides a hydrochemical and geomicrobial ...

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 ...

COP and SPF for Heat Pumps Explained
Heat pumps are powered by electricity but unlike conventional electrical heating, a heat pump is highly efficient. If you are looking into heat pumps, you’ll have come across the terms COP and SPF. Coefficient of Performance (COP) of Heat Pumps COP (Coefficient of Performance) is a measure of efficiency. The efficiency of any machine or system can be calculated as the ratio of amount of ...

Proof: For superior energy efficiency - Water Beats VRF - Case Study
ASHRAE’s Apples to Apples Comparison Proves Hydronics Delivers Superior Energy Efficiency over VRF For years Variable Refrigerant Flow (VRF) manufacturers have been touting their systems’ superior energy efficiency over hydronics without providing the supporting data. Then ASHRAE decided to showcase both systems in its Atlanta headquarters and meter their performance. The results ...

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 ...

Heather glen country house hotel – renewable energy advice case study
Background Heather Glen Country House Hotel in Cumbria was undertaking a major extension and alterations to the premises and sought advice from Envirolink Northwest on how to make energy improvements. Envirolink Northwest recommended a switch from LPG to a renewable biomass fuel, which was followed by assistance with an application for a local grant to help with the cost. The grant was awarded to ...

Air Source Heat Pumps Guide
Using similar technology to that in your refrigerator, an air source heat pump is able to absorb ambient heat from the outside air and deliver it into your home for use with heating systems and in domestic hot water. Here we look at how they work, how to tell if your home is suitable and some of the considerations you’ll need to take into account. How do air source heat pumps work? ...

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 ...

Strada Global: Why we need to rethink the map on Geothermal
For decades, everything we’ve known about geothermal potential has been modelled on a map that shows available resources in some parts of the world, but not others. We need to change that mindset and make people aware that we’re standing on vast resources of geothermal heat, wherever we are in the world. When it comes to geothermal, there are hurdles in people’s minds. They ...

Bio-SNG featured in energy world in February 2011
The use of bio-fuels for heating and lighting pre-dates the use of fossil fuels by thousands of years. However, unlike with fossil fuels, a systematic knowledge of the challenges posed by solid bio-fuels is not as widely understood, a fact attributable to the exponential acceleration of fossil fuel usage as global demand increased during the industrial revolution. In the wake of this, producers ...
