摘要： 文章针对某单相流体回路地面原理样机，提出采用泵变频调速技术进行控温，并对系统控温特性进行了地面试验研究，整个瞬态试验过程中控温精度一般都在±0.3℃以内，最大波动也基本不超过±0.5℃，基于泵变频调速技术的热控制策略性能优良、有效，试验结果可供实际工程设计参考。

Abstract: The traditional temperature control mode using temperature sensing valve has three deficiencies with the reliability, dynamic behavior, pump operational efficiency. In order to solve these problems, a new thermal control technology based on variable frequency pump was put forward for a fluid loop prototype model. The temperature control performance of the thermal control technology based on variable frequency pump was tested. During all transients, the controlled temperature was within the range of ±0.3℃ around the setpoint, with a maximum admissible variation range of ±0.5℃. Thermal control strategy based on variable frequency pump has effective performance.
