5203 |a"Earth to air thermal exchangers (EATEX) can provide a passive means of preheating and precooling ventilation and process air, thereby reducing reliance on electricity and fossil fuels. Their performance is governed by a series of interconnected variables such as tube material, length, diameter and layout; tube depth below grade; surface and deep soil conditions; ambient air temperatures and surface solar radiation; air flow, velocities, fan characteristics and operating schedules. The relationships between the soil, tube design, ambient air, and air velocity are quite complex. This document outlines the fundamental design principles and then applies these principles using complex energy simulation tools. The results of these complex sub-hourly simulations are then loaded into a tool that designers can use at the early design stage to assess the energy performance of design options for a series of Canadian climates"--Abstract.
