DESIGNING METHOD OF VENTILATION SYSTEM AND VENTILATION SYSTEM FOR BUILDING

摘要

PPROBLEM TO BE SOLVED: To provide a designing method of a ventilation system and the ventilation system for a building capable of reducing equipment cost, building cost and running cost, and capable of rationally setting a ventilation quantity. PSOLUTION: A replacement type gravity natural ventilation system for supplying and delivering air by using a driving force obtained by the buoyancy of inside air is adopted, only an air supply port is required as an air supply means, an air blower or an air supply duct is not required to be used, and the equipment cost for installing them or the building cost for securing an installation space can be reduced, and the electric power for driving the air blower is necessary, and energy saving can be promoted and the running cost can be suppressed. The temperature distribution of the inside air is simulated with high accuracy by repeated operations, and thereby an actual ventilation quantity based on the buoyancy of the inside air can be accurately calculated, and the natural ventilation system can be rationally designed.
