Finally, a novel in-situ monitoring study of an air-to-water heat pump in Ireland is presented. Of the 378 heat pumps reviewed, it was found that the average seasonal performance was 2.59, significantly lower than typical product rated performances. Three reasons for this underperformance include...
The maritime climate of the islands and western coast of continental Europe is suitable for the use of air source heat pumps, working in the heating mode only, for domestic space heating. Field trials of several types of air to air and air to water heat pump systems in homes in Ireland ...
Frescold Services offer Air Conditioning Ventilation and Refrigeration to the South East and rest of Ireland.
In this work, operational optimisation is performed of an air-source heat pump system aimed at providing space heating and domestic hot water to a single-family dwelling. The novelty of this work lies in the development of comprehensive thermal network models of two different system configurations:...
Six cases having installed an air-to-air heat pump and realized two other energy efficiency actions, two cases having installed a water-to-water heat pump and one case having installed an air conditioning system out of the operation.
“The liquid piston is our invention - and it’s one of the elements that enables this to work with really large underground reservoirs,” says Ramamurthy, adding that moving a body of water “make this less compressed air and more pumped hydro. ...
Air source heat pumpHeat pumps are proven energy efficient space heating devices for homes in UK and Ireland. Ground source heat pumps (GSHPs) are best suited to new installations where it is possible to install underfloor heating and the necessary ground coils or bore holes without disruption....
The hot water valve then must be normally open. For VAV systems such as this one, reheating of supply air will occur at the VAV boxes when zones require heat. To reduce this inefficiency, the supply air temperature set point may be reset. Various strategies have been used for reset ...
The latent heat of condensation of the humidity allows the balloon to go much higher, up to 10 km. For the descent, the drive balloon is emptied of the hot air at its maximum altitude. The support balloon slows down the descent. The water condensate can be recycled [158]b. In a ...
to water usage being expensive only the wealthiest could afford it. An earlier form of air conditioning was invented in Persia (Iran) thousands of years ago in the form of wind shafts on the roof, which caught the wind and passed it through water and blew the cooled air into the building...
