Impact of air-flow on thermal performance of air-spaces behind cladding (ASHRAE 1759-TRP)

Dolaana Khovalyg, Mohammad Rahiminejad

The project ASHRAE 1759-RP addresses the impact of the ventilated cavity behind external claddings on the thermal performance of the wall structure by defining “effective thermal resistance” of air gaps based on the linearized network of thermal resistance ...

A data-driven model for the air-cooling condenser of large-scale coal-fired power plants based on data reconciliation and support vector regression

François Maréchal, Ligang Wang, Ivan Daniel Kantor, Jean-Loup Sylvain Robineau

The performance of a direct air-cooling condenser under operation is rather complicated, as it is interactively affected by the operating conditions (e.g., the mode of air fans) and ambient conditions (e.g., temperature and wind speed). To understand the c ...
