Thermal Assessment of a Novel Combine Evaporative Cooling Wind Catcher
energies Article Thermal Assessment of a Novel Combine Evaporative Cooling Wind Catcher Azam Noroozi * and Yannis S. Veneris School of Architecture, National Technical University of Athens, Section III, 42 Patission Av., 10682 Athens, Greece; [email protected] * Correspondence: [email protected]; Tel.: +30-210-772-3885 (ext. 3567) Received: 5 January 2018; Accepted: 13 February 2018; Published: 15 February 2018 Abstract: Wind catchers are one of the oldest cooling systems that are employed to provide sufficient natural ventilation in buildings. In this study, a laboratory scale wind catcher was equipped with a combined evaporative system. The designed assembly was comprised of a one-sided opening with an adjustable wetted pad unit and a wetted blades section. Theoretical analysis of the wind catcher was carried out and a set of experiments were organized to validate the results of the obtained models. The effect of wind speed, wind catcher height, and mode of the opening unit (open or closed) was investigated on temperature drop and velocity of the moving air through the wind catcher as well as provided sensible cooling load. The results showed that under windy conditions, inside air velocity was slightly higher when the pad was open. Vice versa, when the wind speed was zero, the closed pad resulted in an enhancement in air velocity inside the wind catcher. At wind catcher heights of 2.5 and 3.5 m and wind speeds of lower than 3 m/s, cooling loads have been approximately doubled by applying the closed-pad mode.

The Wind-Catcher, a Traditional Solution for a Modern Problem Narguess
THE WIND-CATCHER, A TRADITIONAL SOLUTION FOR A MODERN PROBLEM NARGUESS KHATAMI A submission presented in partial fulfilment of the requirements of the University of Glamorgan/ Prifysgol Morgannwg for the degree of Master of Philosophy August 2009 I R11 1 Certificate of Research This is to certify that, except where specific reference is made, the work described in this thesis is the result of the candidate’s research. Neither this thesis, nor any part of it, has been presented, or is currently submitted, in candidature for any degree at any other University. Signed ……………………………………… Candidate 11/10/2009 Date …………………………………....... Signed ……………………………………… Director of Studies 11/10/2009 Date ……………………………………… II Abstract This study investigated the ability of wind-catcher as an environmentally friendly component to provide natural ventilation for indoor environments and intended to improve the overall efficiency of the existing designs of modern wind-catchers. In fact this thesis attempts to answer this question as to if it is possible to apply traditional design of wind-catchers to enhance the design of modern wind-catchers. Wind-catchers are vertical towers which are installed above buildings to catch and introduce fresh and cool air into the indoor environment and exhaust inside polluted and hot air to the outside. In order to improve overall efficacy of contemporary wind-catchers the study focuses on the effects of applying vertical louvres, which have been used in traditional systems, and horizontal louvres, which are applied in contemporary wind-catchers. The aims are therefore to compare the performance of these two types of louvres in the system. For this reason, a Computational Fluid Dynamic (CFD) model was chosen to simulate and study the air movement in and around a wind-catcher when using vertical and horizontal louvres. -
