Based on a computing model of floor heating residences, indoor thermal environment and heat distribution under the effect of heat charge/discharge, operation control and solar radiation has been concluded. Concept and formula of equivalent heat supply has been put forward which indicate that actual heat supply will be equal to the sum of design heat supply and equivalent heat supply. Recommend coefficient has been given taken Dalian as an example. Computed according to the new method, design heat supply can be reduced to 37% in cloudy day and 43.3% in sunny day, energy saving effect is very obvious. In Tromb wall solar house, effect of concrete wall on indoor temperature swing and attenuation of temperature wave is very obvious. While the outdoor air-temperature swing exceeds 10℃, indoor air-temperature swing belows 3℃. In the experiment, maximal difference in temperature between inner surface and outer surface of the 300mm wall exceeded 10℃. Heat storage and collector efficiency varies adversely according to solar radiation. Factors such as thickness, material, absorptance of the wall and permeation of the glass cover all have big influence on heat storage and collector efficiency. There exsisted an optimal thickness of the wall, which can make the best of heat storage and collector efficiency. Most of the heat stored in conventional Trombe wall during the daytime has been lost to the outside at night without heat preservation. Heat preservation on the outside surface of the wall has effectively improved heat release performance of the wall at night, heat supply to the room has increased too.
