建立了制冷系统的状态空间模型，研究了制冷系统的动态特性。采用向量矩阵表示法和线性化方法，将描述冷水机组动态热力特性的常微分方程组转化为状态空间的表示形式。该模型已被一系列的制冷剂R-134 a的冷水机组的动态响应实验验证。在实验工况下，模型计算结果与实验数据的平均误差均小于10%。然后，利用该模型研究了蒸发器出口冷载体温度在不同A扰动下的瞬态特性。本研究中开发的状态空间模型有助于我们有一个很好的想法在瞬态条件下的制冷系统的动态性能和设计优化的控制策略，高能效的暖通空调系统。
A state-space model has been developed to investigate the dynamic behaviors of refrigeration system. By using vector-matrix notation and linearization, the ordinary differential equations describing the chiller's dynamic thermal behaviors are transformed into a representation form of the state space. The model has been validated by a series of dynamic response experiments of a chiller with the refrigerant R-134a. The average errors of the model results compared with the experimental data are all less than 10% in the experimental cases. Afterward, the model is used to investigate the transient behaviors of the exit cold carrier temperature of evaporator under differentAdisturbances. The state-space model developed in this study helps us have a good idea of the dynamic performance of a refrigeration system under transient conditions and design optimized control strategies for a high-energy-efficiency HVAC system.
