Total Air Conditioning 1

Ultra Efficient Total Air Conditioning in One Package

This unit, built for an Elementary School in Michigan, is the ultimate in year-round efficiency. Under summer conditions, it uses a highly efficient AIRotor® hygroscopic heat wheel to recover energy from the exhaust airstream and pre-cool and dehumidify warm outdoor air. The flat plate exchanger then further cools the supply air before the on-board heat pump and DX coil provide final cooling. The flat plate exchanger is then used for reheat. In the winter, the heat wheel preheats the air before the same heat pump and coil complete the required heating. This unit
will provide total year-round air conditioning at the lowest possible operating cost.
