Abstract

The needs to reduce pollutant emissions and the energy consumption, due to the growing energy demand, to the increased environmental consciousness of people in the world and to the increased price of crude oil, have been the fundamental engine for the development of innovative technologies in the field of heating and cooling systems in large buildings. Ground source heat pump (GSHP) systems have a good environmental compatibility and low impact on rooms reserved to heating and cooling systems in buildings. The choice of the GSHP has to be justified in many applications, such commercial and industrial buildings, by cost advantages. This work verifies numerically, with the help of the CFD code Fluent, the operating conditions for horizontal slinky heat exchangers, placed under the ground level areas of the South of Italy, that had to be provided with an air conditioning system for both winter and summer. In particular, the dependence of the cost and the effectiveness of the system on the parameters like the tube diameter, the depth of installation and the water inlet temperature has been investigated.
