AIR-CONDITIONING CONTROL SYSTEM USING NATURAL VENTILATION CREATED BY WIND BLOWN BY TRAIN

摘要

PROBLEM TO BE SOLVED: To provide an energy and space saving type air conditioning system and its method by utilizing the amount of natural ventilation created by winds blown by train in an underground space such as premises ofsubway stations with which excessive mechanical facilities for air supply and exhaust can be made simpler and the areas of ventilation towers, ventilators, and air conditioning facilities can be reduced and also by predicting heat environment grasped by the winds blown by the trains. SOLUTION: The amount of ventilation created by the winds blown by the trains in a subway space such as train platforms and in tunnels is measured by train operation diagrams, train running speed detectors 5 or wind velocity detectors installed at stairs at the time of start and arrival of the trains. Based on the amount of natural ventilation, the amount of air supply from fresh air above the ground is reduced to a volume conforming to the ventilation criteria and the minimum amount of the outside air required is calculated; signals for temperature detectors installed in the underground space such as platforms and concourses are input and the temperature control and air conditioner control for each air conditioning unit are performed by using an air-conditioning load computing and controlling means 2 which provide a minimum power for the air conditioners.
