本文提出了一个吸收式制冷机和热泵的模型，该模型将这些机器的特性简化为两个简单的代数方程:一个用于容量，一个用于COP。然而，这些方程仍然包含系统的完整热力学信息（以稍微简化的形式），它们可以解析求解。如果操作条件范围不太大，则使用该模型获得的结果仅与精确的数值模拟略有偏差。由于其简单性，该模型非常适合作为一个非常稳定和快速的吸收机模块纳入能源系统仿真包中。 另一个主要好处是，它是一个合适的工具，用于拟合商业设备的目录数据，以便以系统模拟应用所需的计算机形式提供其运行特性。该模型已成功应用于商用单效溴化锂/冷水机组和水/氨热泵的目录数据。单位:SICitation:研讨会，ASHRAE交易，第105卷，第页。1.

This paper proposes a model of absorption chillers and heat pumps that reduces the characteristics of these machines into two simple algebraic equations: one for the capacity and one for the COP. These equations, however, still contain the complete thermodynamic information of the systems (in a slightly simplified form), and they can be solved analytically. The results obtained with the model deviate only marginally from exact numerical simulations if the range of operating conditions is not too large. Due to its simplicity, the model is well suited to be incorporated as a very stable and fast absorption machine module in energy system simulation packages. A further major benefit is that it is an appropriate tool for fitting catalog data of commercial equipment so that their operating characteristics become available in the computerized form required for system simulation applications. The model has been successfully applied to catalog data of commercial single-effect lithium bromide/water chillers and water/ammonia heat pumps.Units: SI
