随着节能的需要和计算机的广泛应用,自六十年代后期开始,空调负荷的计算方法不断得以革新。在充分考虑房间物体的蓄热一放热作用的基础上,这些新方法在机理上更趋完善,其计算结果也更为符合实际。在新出现的方法中,目前研究应用较广也较为先进的是Z变换法。近年来我国也在这方面开展了应用研究。本文不单纯介绍这一方法,而是着重从基础入手循序地对如何运用控制工程的传递函数理论来解决空调负荷计算问题的整个思路作系统而简要的介绍,但不作严密和详细的数学推导。除Z变
With the need for energy conservation and the widespread use of computers, the calculation method of air conditioning load has been continuously innovated since the late 1960s. After fully considering the heat-releasing effect of the room objects, these new methods are more perfect in mechanism and their calculation results are more realistic. Among the newly emerged methods, Z-transform method is widely used and advanced. In recent years, China has also applied research in this area. This article does not simply introduce this method, but focuses on the basic idea of how to use the transfer function theory of control engineering to solve the whole idea of the air-conditioning load calculation system and a brief introduction, but does not make strict and detailed mathematical derivation. In addition to Z change
