空调系统的一种集总参数模型

One Lumped Parameter Model of Air-conditioning System

空调系统模型的研究对改善系统性能有重要意义。建立的一种集总参数法热力学模型与现有空调系统模型相比,不需要对空调内部各个部件分别建模计算,达到平衡,再进行系统平衡计算,而是选出各个部件模型中与系统模拟密切相关的热力参数,建立其模型,然后直接对所有未知变量同时迭代求解。建立的集总参数法热力学模型具有物理概念清晰、计算过程简明科学、迭代次数少、速度快等优点。

The research on air-conditioning system has important significance on improving system performance.Compared with the current air-conditioning system model,rather than respectively conducting modeling calculation on each parts of air conditioner interior and calculation of balance of systems after reaching to balance,the thermodynamic model of lumped parameter method built only chooses thermal parameter of each component models which is closely related to system simulation,establishes its model and settles iterative solutions directly to all the unknown variables at the same time.The thermodynamic model of lumped parameter method built features advantages of distinct physical concepts,simple and clear calculation process,less iterations and fast speed etc.
