已经开发了一个计算机代码，用于以灵活的模块化形式模拟吸收系统，这使得研究具有不同工作流体的各种循环配置成为可能。代码基于单元子程序，包含系统组件的控制方程。这些由主程序根据用户的规范连接在一起，形成完整的系统。同时求解方程，并从属性数据库中获取流体属性。该代码面向用户，需要一个相对简单的输入，包含给定的操作条件和每个状态点的工作流体。 用户通过指定不同的子单元及其互连，向计算机传送其循环的图像。根据这些信息，程序计算系统中每个状态点的温度、流速、浓度、压力和蒸汽分数，以及每个单元的热负荷，从中可以确定性能系数。该程序已成功地用于模拟各种单级、双级和双回路热泵和热变压器，工作流体包括LiBr-H20、H20-NH3、LiBr/H20-NH3、LiBr/ZnBr2-CH3OH等。 单位:双引文:研讨会，ASHRAE交易，1987年，第93卷，第。田纳西州纳什维尔2号

A computer code has been developed for simulation of absorption systems in a flexible and modular form, which makes it possible to investigate various cycle configurations with different working fluids. The code is based on unit subroutines containing, the governing equations for the system’s components. Those are linked together by a main program according to the user’s specifications to form the complete system. The equations are solved simultaneously, and fluid properties are taken from a property database.The code is user-oriented and requires a relatively simple input containing the given operating conditions and the working fluid at each state point. The user conveys to the computer an image of his cycle by specifying the different subunits and their interconnection. Based on this information, the program calculates the temperature, flow rate, concentration, pressure, and vapor fraction at each state point in the system and the heat duty at each unit, from which the coefficient of performance may be determined.The program has been used successfully to simulate a variety of single-stage, double-stage, and dual-loop heat pumps and heat transformers, with the working fluids LiBr-H20, H20-NH3, LiBr/H20-NH3, LiBr/ZnBr2-CH3OH and more.Units: Dual
