As a fundamental concept for dynamic component of the climate system, resilience is typically defined as the ability of individual trees, forests or ecosystems to resist sudden disturbances and recover to their initial state (Holling, 1973; Simoniello et al., 2008).Given the large potential of vegetation to take up atmospheric …
WebA heat exchanger is a component that allows the transfer of heat from one fluid (liquid or gas) to another fluid. Reasons for heat transfer include the following: 1. To heat a cooler fluid by means of a hotter fluid 2. To reduce the temperature of a hot fluid by means of a cooler fluid 3. To boil a liquid by means of a hotter fluid 4. WebThe earth tube is part of the supply air system. Building return air or exhaust air does not interact with the earth to air thermal exchanger (EATEX). In a closed system, building air is recirculated through the buried pipe system to transfer building heat to the earth, thereby cooling the building.
