A Thermodynamic Computer Simulation of an Air-To-Air Heat Pump System for a Commercial Building

摘要

The development of a computer simulation program for an air to air heat pump system by using specific procedures proposed by ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) is presented. The program is to be used to optimize the heat pump system by changing set points, temperature schedules, and control arrangements; and to predict energy consumption over given periods to compare with energy consumption predicted by the system simulation program for the installed system. Included in the report are: a description of the building and installed environmental control system used in the study; specific steps in the heat pump system simulation development, including guidelines, limitations, and basic system simulations for cooling and heating cycle operations; a basic system sensitivity study; system modification and experimentation; a comparison between the heat pump system and the installed system; and conclusions and recommendations. Definition of variables, the computer program listing, and typical results are contained in the appendix.
