Abstract
The mathematical model of the envelop enclosure of the room, radiator and thermostat valve was built, and several equations based on the heat balance theory of room were solved. The dynamic characteristics of indoor temperature, heat medium flow and heat dissipating capacity of radiator, and the temperature of each layer of the external walls were obtained. The study result shows that inside temperature of insulation layer of the outer wall changes very little when outdoor temperature changes within 10°C; The method of regulating heat medium flow of radiator by thermostat valve has little influence on the indoor temperature, and the indoor temperature is also affected by the wall heat storage and release.
