精密空调应用广泛,但在精密空调应用场所,空调系统能耗占场所总能耗的很大比例。为优化精密空调运行及节约能耗,建立基于能耗模拟的精密空调温湿度协同控制优化运行模型。采用热平衡理论,结合场所室内设备的散热功率及室外温度变化,建立室内温度设定值与空调负荷的热平衡方程;进一步考虑室内外相对湿度的差异,建立空调加湿与除湿的能耗平衡模型;并以空调运行的经济性和稳定性为目标,建立精密空调温湿度协同控制优化运行模型。采用理想点法和遗传算法对模型求解,实现兼顾稳定及经济性的空调运行方式的优化控制,最后通过算例分析证明模型的正确性和有效性。
Precision air conditioning is widely used, but in precision air conditioning applications, air conditioning system energy consumption accounts for a large proportion of total energy consumption. In order to optimize the operation of precision air-conditioners and save the energy consumption, an optimal operating model of temperature-humidity coordinated control of precision air conditioners based on energy consumption simulation is established. Based on the theory of heat balance, combined with the cooling power and the outdoor temperature change of indoor equipment, the heat balance equation between indoor temperature setting value and air conditioning load was established. Then the difference between indoor and outdoor relative humidity was further considered to establish the energy consumption balance model of humidifier and dehumidifier. Aim at the economy and stability of air-conditioner operation, and establish the optimal operation model of temperature and humidity coordinated control of precision air-conditioner. The ideal point method and genetic algorithm are used to solve the model to realize the optimal control of the stable and economical operation mode of air conditioning. Finally, the correctness and effectiveness of the model are proved by the example analysis.
