Heat Pumps

The heat pump learning solution helps students develop a solid understanding of typical domestic heat pumps.

Clearly-identified, separate circuits connect through a 4-way reversing valve to demonstrate the cooling and heating modes of operation. Timed automatic defrost, as well as back-up electric heating, are also covered. Students use manual and programmable thermostats to implement different scenarios in a plenum chamber.

Topics Covered

  • Blowers and ducting simulate distribution methods of heating and cooling
  • Several test points
  • Electric heat for secondary heating
  • Capillary-tube controls with check valves
  • Controls that include manual and programmable thermostats, fan/limit temperature sensor, high-pressure controller, low-pressure controller, and defrost timer
