Hygro-thermal performance of earth-to-air heat exchanger: long-term data evaluation and short-term simulation

Popis výsledku v původním jazyce

The thermal comfort requirements and cooling energy demand have significantly increased during the last twenty years. Air heating and/or cooling in an earth-to-air heat exchanger (EAHX) is a possible approach for improvement of thermal comfort in a building and for reduction of ventilation heat loss. A passive family house using mechanical ventilation system equipped with heat recovery and simple EAHX is being monitored since the end of summer 2005. The paper deals with the evaluation of measured data collected during year 2006. Amongst others, the results show the tendencies in moisture performance of monitored EAHX. Besides pure data evaluation, the short-term hygro-thermal simulation of EAHX was performed with a numerical model specially developed for this purpose. The simulation is compared with the monitored data; the comparison serves as the basic experimental validation of the model.
