DEVELOPMENT OF A SMALL INTEGRATED HEAT PUMP (IHP) FOR NET ZERO ENERGY HOMES


An integrated heat pump (IHP) prototype was developed and tested over a range
of operating modes and conditions. Test data was used to validate a detailed analysis model
and the validated analytical tool was used to calculate the yearly performance of air- and
ground-source IHP system designs optimized for R-410A in five major US cities. For the airsource
IHP version, the simulation results showed ~46-67% energy savings depending upon
location. For the ground-source IHP version, the simulation showed over 50% savings in all
locations.
