Research tool for use in the steady-state simulation and design analysis of heat pumps and air conditioners. The program can be used with most of the newer HFC refrigerants as well as with HCFCs and CFCs. The standard vapor-compression cycle is modeled with empirical representations for compressor performance and first-principle region-by-region modeling of the heat exchangers.
An online Mark VII Web version is available that can be used with default configurations or with user-specified component and operating parameters for analyzing the performance of single-speed, air-to-air equipment. User configurations can be saved for later use. Parametric analyses can be conducted.
Another online Web version can be used to model dehumidifiers at https://web.ornl.gov/~doehpdm/hpdm/MarkVI_DH.shtml
A downloadable desktop version for Windows with Excel-generated text file input is also available on the home page of the Mark 7 web site. That version can also be used to model multi-speed, water-to-air, and water-to-water heat pumps as well as dehumidifiers and evaporative condensers.
