WebJul 11, 2024 · Today, earth–air heat exchangers (EAHEs) are important heat exchangers used in the air-conditioning of buildings and can be seen in different types and capacities. Thermal comfort is perceived as the comfort of human beings under given room conditions, namely average temperature and relative humidity. WebA quasi‐steady state, three‐dimensional model was developed for simulation of earth‐air heat exchanger (EAHE) system. The simulation model of EAHE system was developed in CFD platform CFX 12.0. The simulation results were validated against experimental results obtained from experimental set‐up installed at Bhopal (Central India).
