A Meteorological New Method for Analysis on the Capacity of Cold-protection of House

Abstract

Under considerations of natural ventiration caused by the temperature difference between room air and open air, and total heat transmission through the room-walls, the author obtained theoretically the following equation,
where θ and T denote temperature of room air and open air respectively, t time and β', η' constants.
In this paper the author determined analytically in several cases the value of η' and β' which indicate the capacity of cold-protection of house, comparing the solution of the above equation with observational data of θ and T.
The coincidence between the results obtained analytically and those obtained from the observation was considerably good.
