Solutions for Energy Conservation and Pollution Reduction: Earth-Air Heat Exchangers

Cătălin Teodosiu, Lidia Niculiţă, and Raluca Teodosiu
Abstract—The aim of this work is to evaluate the capacity of earth-air heat exchanger (EAHX) systems to contribute to energy and pollution savings for heating and cooling of buildings. This is fulfilled by means of numerical simulations (dynamic regime) based on coupled model: “weather file/soil model/EAHX/ventilation system/building. Detailed results concerning EAHX efficiency, energy conservation and pollution reduction (in comparison with classical solutions for winter heating and summer cooling), are shown for three different Romanian regions for a single-family separate house.

Index Terms—Earth-air heat exchanger, energy saving, greenhouse gas emission reduction, modeling, simulation, ventilation.
