Abstract
An air-conditioning and ventilation simulator for predicting environmental conditions in a subsurface space, which includes a first processing portion for obtaining the airflow velocity in branches constituting the subsurface space; a second processing portion for calculating initial values and short-term change values of wall temperature and field temperature in each of the branches, initial values and boundary values of temperature, water-vapor density and carbon dioxide concentration in each of the branches; a third processing portion for calculating the wall temperature, field temperature and airflow temperature in each of the branches; and a fourth processing portion for performing detailed calculation of the airflow velocity, temperature, humidity and carbon dioxide concentration for calculating time-varying data of the airflow temperature, water-vapor density and carbon dioxide concentration in each of the branches by using, as input data, the space structure model data, the airflow analysis result data obtained from the first processing portion, the thermal analysis result data obtained from the second processing portion, and wall and field temperature data obtained from the third processing portion.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
