<P>PROBLEM TO BE SOLVED: To provide a system for estimating a ventilating state and a temperature state in a building with high accuracy, and accurately estimating an indoor air quality state by taking account of influences of heat transfer and heat generation into a calculation of a ventilation circuit network. <P>SOLUTION: The system includes an input means, a calculating means and an output means. The calculating means determines a ventilation amount of air in each room by considering buoyancy caused by the difference in air densities depending on temperature, also calculates a ventilation amount of each opening, and calculates the temperature of each room on the basis of input and output quantities of heat in each room while considering heat transfer accompanying ventilated air, heat capacities of intervening objects such as walls between adjoining rooms, floors, ceilings, doors, and glass, and surface temperatures of the intervening objects, and considering a heat capacity of an earth floor and the surface temperature of the earth floor in the room, and regarding the surface temperature in the earth floor on the ground to be equal to the ground temperature. <P>COPYRIGHT: (C)2012,JPO&INPIT |
