DOE/ORNL Heat Pump Design Model

The DOE/ORNL Heat Pump Design Model is a research tool for use in the steady-state design analysis of air-to-air-heat pumps and air conditioners.

The WEB version has an HTML-based input interface which generates the required input text file, executes the FORTRAN application, and summarizes the results on your Web browser.

As this is a hardware-based model, the user can specify the heat exchangers and air flows and select a compressor. The flow control devices may be specified or sized by the program based on desired conditions leaving the heat exchangers. The program analyzes steady-state performance for indoor and outdoor air conditions provided by the user. An example case is provided.

The Web version also has parametric analysis capability. A variety of performance trends can be viewed for a range of operating or design variables.
