The standard way of providing climate control inside most commercial facilities is with the air-source heat pump. You’re most likely familiar with these as the rooftop units found on commercial buildings. They work through refrigeration circulation to move heat either into or out of a facility space. The reason they’re called “air-source” heat pumps is because the use the air both indoors and outdoors for heat transfer.
But what other option is there aside from using the air? The ground! The ground-source heat pump draws and deposits heat in the ground beneath the frost line, allowing it to either heat or cool the air inside a space. You know this type of HVAC system better as a geothermal system.
