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 ...

Performance assessment of an integrated absorption cooling–hydrogen liquefaction system using geothermal energy
An integrated geothermal based triple effect absorption cooling and Linde–Hampson system for hydrogen gas liquefaction is proposed and analysed thermodynamically. The effect of various operating conditions and parameters on the system performance is studied. The results show that the mass of hydrogen gas pre–cooled by the absorption system per unit mass flow rate of geothermal water flowing ...

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 ...

Investigation of a hybrid solar and geothermal driven absorption cooling system for district applications
In this paper, a new hybrid geothermal and solar driven absorption cooling system (ACS) is proposed for low–temperature district energy applications. Two approaches are proposed in this study, namely: a) a new model for determining the specific entropy values of LiBr–water solution and (b) two new energetic and exergetic parameters, namely geothermal contribution index and solar contribution ...

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 ...
