Our site features a 2-ton residential SolarHVAC unit.
In lieu of generating electricity, the solar panel on the iAIRE Solar HVAC generates heat. The Solar HVAC unit utilizes the sun’s energy to put heat into the refrigerant. This process replaces a portion of the energy the compressor would normally put into the system from the electrical network in the building.
The Solar panel is installed on the condensing unit. There is a VFD installed on the compressor. There are sensors in the condensing unit that sense pressure or temperature and provide feedback to the HVAC controls indicating how the system is operating. As the solar panel adds more heat to the system, the VFD slows down the speed of the compressor to keep the system running at its normal operating pressure. As the compressor runs slower, it utilizes less electricity to operate. The compressor is normally the item in the HVAC system that uses the most energy. many times utilizing up to one-half the energy normally required to operate an HVAC system.
