DOE/ORNL Heat Pump Design Model (HPDM)

Welcome to the new and improved HPDM on the web

The DOE/ORNL Heat Pump Design Model is a research tool for use in steady-state and quasi-steady-state design analyses of extensive thermal system configurations and HVAC applications. The WEB version has an HTML-based input interface which generates the required input file, executes the application, and summarizes the results on your Web browser.

As this is a hardware-based model, the user can specify the inputs of each component, i.e. compressor, heat exchanger, fan and pump, etc. The program analyzes steady-state performance for indoor and outdoor operation conditions provided by the user. An example case is provided for each individual system configuration. The user can download and upload a simulation case to the server. In addition, a desktop version, using an interface of Excel Add-In is available for the user to download (link at the bottom of this webpage) and use at a personal computer.

The wizard will guide you through the generation of your heat-pump design model input file. The wizard includes extensive configurations in numerous application categories. You are more than welcome to work with us and create other new configurations for your interest. If you have suggestions or find any bugs related to this modeling and design tool, please contact the author, Bo Shen, shenb@ornl.gov.

Below, you can either expand a category by clicking the triangle on the left, select an existing configuration and customize; or upload your previously saved configuration (files) to begin.
