摘要

焓差实验室设计用于空调性能测试，可以模拟环境条件。采用焓差法对空调制冷能力和制热能力进行了研究。实验室的温度由三台加热器、五台冷水机和电动机控制。由于设备功率和房间大小的影响，温度控制具有非线性和强滞后的特点。本文采用建模方法得到较好的温度曲线。得到了四种温度模型，并通过比较选择了两种合适的控制模型。最后，根据实验数据确定实验室模型，并采用合适的方法进行温度控制。通过仿真验证了所提方法的有效性。

Modeling and Control of Temperature in Enthalpy Difference Laboratory

The enthalpy difference laboratory is designed to test the air conditioner performance, which can simulate the environmental conditions. The enthalpy difference method is used to investigate the refrigeration ability and heating capacity of air conditioner. The temperature of the laboratory is controlled by three heaters, five chillers and motors. Due to the influence of equipment power and room size, the temperature control has the characteristics of nonlinearity and strong hysteresis. In this paper, the modeling method is used to get a better temperature curve. We got four temperature models, and choose two suitable control models through comparison. Finally, the laboratory model is determined by experimental data and the apropriate methods is adopted to control the temperature. The simulation is carried out to verifies the effectiveness of the proposed methods.
