本文在上海典型冬季工况下,测试了太阳能驱动的除湿换热器系统的采暖加湿性能。同时针对再生热水温度、再生热水流量和再生风量等三个影响再生过程的重要因素进行了实验研究。结果表明,除湿换热器系统在冬季工况下可以有效实现采暖加湿,并在热水温度为40℃,流量为0.4 kg/s,再生风量为400 m~3/h的工况下达到最佳送风状态。此时送风含湿量为5.15kg/s,系统热力学性能系数(COP_(th))达到1.78。同时,针对冬季环境含湿量的变化提出了不同的风量控制策略,实现送风温湿度和系统性能的最优化。
This paper tests the heating and humidifying performance of the solar-driven dehumidification heat exchanger system under typical winter conditions in Shanghai. At the same time, three important factors affecting the regeneration process, such as regenerative hot water temperature, regenerative hot water flow and regenerated air volume, were studied experimentally. The results show that the dehumidification heat exchanger system can effectively achieve heating and humidifying in winter conditions and reaches the maximum under the conditions of a hot water temperature of 40 ℃, a flow rate of 0.4 kg / s and a regenerated air volume of 400 m 3 / h Good air condition. At this time, the air moisture content is 5.15 kg / s, and the coefficient of the thermodynamic performance (COP_ (th)) reaches 1.78. At the same time, different air volume control strategies are proposed according to the variation of the moisture content in the winter, so as to optimize the air temperature, humidity and system performance.
