Study On Incorporate System Of Canulate Exterior Shading And Natural Ventilation Design

Shading and natural ventilation are two kinds of traditional and effective energysaving technology and the important means and methods of realization of buildingenergy saving and indoor thermal environment improvement. Shading construction isable to reduce indoor thermal load effectively，as to prevent indoor environment fromoverheat in summer; Natural ventilation，by means of the thermocompression and windpressure，exchange air of outdoor for indoor，carry off the indoor waste gas and overheateffectively，maintain the indoor air fresh.Both of Shading and Natural ventilation are sustainable passive energy savingtechnology，however，at present research on the relationship of them is less thanexpectation.In the basic on previous theory and research experience in the shade， naturalventilation， solar energy， author come up with a new concept as Incorporate systemof Canulate ExteriorShading and Natural Ventilation (ISV system for short). Thesystem is a kind of energy saving system with double function. By the constructionreformation， the Exterior Shadings was transformed into the canulate shading boardwith a hollow air cavity. The air cavity was connected with indoor and outdoorenvironment in some way. Air in the cavity will be heated by solar radiation when theshading board was exposed in the sun. The themocompression will be engendered as thedrive of natural ventilation. In this way，the ISV system could achieve the both aims ofsolar shading and natural ventilation improvement.Content of this thesis:1. Present the concept of Incorporate system of Canulate Exterior Shading and NaturalVentilation. Design the construction of the ISV system Preliminary. 2. Proof the system operation principle，namely the physical theory feasibility of theISV system.3. Establish the mathematical model to simulate the system performance in summerworking condition，and to evaluate the ventilation effect.4. Alter the measurement of ISV system， make a Further discussion about therelationship of the measurement and ventilation by comparison of the simulateconsequence.
