This mathematical model and its calculating program can be used to measure the thermal performance of passive solar houses with heating systems of sunspace.Its functions are predication of indoor air temperature hour-by-hour ,determing of auxiliary heat amount required and optimum selection of design plans and calculating parameters.
With the experiments of the sunspace solar houses in our country the calculating formulas and the recommended parameters presented in this paper can easily calculate the natural con-vective heat transfer through an opening between the sunspace and the adjoining room. On the other hand,the method for the mean radiation temperature net presented by J·A·Carroll can be used to calculate the radiation heat tranrsfer between the interior surfaces of a room. This new approach is easier as compared with the traditional calculating method and it is also suitable for computer operations.
The calculating program can be operated conveniently on a micro-computer with fairly complete functions. The calculated results are in good agreement with the measured actual values and can meet the requirements of design and research on the same types of solar houses.
