提出一种新型复合太阳能炕系统,该系统由提供被动采暖的太阳能空气集热器和提供主动采暖的太阳能炕系统组成。系统的运行模式是影响室内热环境的重要因素,为寻求最佳的运行模式,在3种运行模式下对系统进行实验测试。结果发现:当系统以晚上模式或下午模式运行时,运行过程中炕体所吸收的热量在之后的放热过程中无法充分释放,且炕面和空气温度的波幅较大;当系统以傍晚模式运行时,炕体能够充分发挥其蓄热优势,使炕面和空气温度的变化相对平缓。
A new solar system with solar energy is proposed. The system consists of a solar air collector that provides passive heating and a solar kang system that provides active heating. The operating mode of the system is an important factor affecting the indoor thermal environment. In order to find the best operating mode, the system is experimentally tested in three operating modes. The results show that when the system is operating in night mode or afternoon mode, the heat absorbed by the kang body during operation can not be fully released during the subsequent exothermic process, and the amplitude of the kang surface and the air temperature is relatively large. When the system operates in the evening mode Run, kang body can give full play to its thermal storage advantages, so that the surface of kang and air temperature changes relatively smooth.
