WebJul 1, 2013 · Earth–air tunnel heat exchanger (EATHE) is one of the passive systems, which utilizes the undisturbed earth temperature to heat and cool the buildings. Authors … The earth–air heat exchanger (EAHE) is a promising technique which can effectively be used to reduce the heating/cooling load of a building by preheating the air in winter and vice versa in summer. In the last two decades, a lot of research has been done to develop analytical and numerical models for the analysis … See more The following assumptions were made in order to simplify the development of the one-dimensional model of the EAHE system: 1. The surface temperature of the ground is defined as equal to the ambient air temperature, … See more The mass flow rate of air is an important parameter, and it must be known by the designer so that the selection of size and number of pipes can be initiated. There is no unique value of … See more The earth’s undisturbed temperature is an important parameter in designing an EAHE system. Assuming homogeneous soil of constant thermal diffusivity, the temperature at any depth z and time t can be estimated by the … See more
