Title:
AIR CONDITION/VENTILATION SIMULATOR IN UNDERGROUND SPACE
Document Type and Number:
Japanese Patent JP2765630
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To correctly simulate the state of air flow in an underground space so as to be able to correctly predict the temperature, humidity, CO2, powdery dust density in the underground space by providing respective specified first to fourth processing parts.
SOLUTION: An air flow/pressure analytic processing part (the first processing part) 1, a caloric analytical processing part (the second processing part) 2, an underground temperature/wall temperature calculation processing part (the third processing part) 3, and an air flow speed/temperature/humidity/CO2 concentration precise calculation processing part (the fourth processing part) 4 are provided. The first processing part 1 finds out the air flow speed of each branch, such as a tunnel, stairs, ventilation port, etc. The second processing part 2 calculates the wall temperature, short period variation quantity of the underground temperature of each branch, and the temperature, steam density, CO2 concentration in each branch. The third processing part 3 makes calculation process of the temperatures in the wall and the earth and an air flow temperature of each branch. The fourth processing part 4 makes precise calculation process of air flow speed, temperature, humidity and CO2 concentration for calculating the time changes data of the air flow temperature, steam density and CO2 concentration of each branch.
