| 摘 要： | 建立了某房间围护结构、散热器、温控阀的数学模型，基于房间热平衡理论联立各模型求解，得出设定条件下室内温度、散热器流量、散热量及外墙各层温度的动态变化规律．研究结果表明：室外温受在10℃温差范围内波动时，外保温外墙的保温层内侧温度受室外温度影响很小，散热器温控阀调节流量对室内温度影响不大，室内温度还受墙体蓄热和放热的影响．

| 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℃ ; 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. |
