Detailed baseline and post measurements were taken of six (6) nominal 10-ton, 4-yr old AAON Roof Top
Heat Pump Units (RTUs) serving the hotel. The primary purpose of this exercise was to

achieved by implementing the energy control measure (ECM) CRYOGENX4.

Additional validation with 1 minute meters measuring current:


Here's how this savings compares to other hotels validated (and over a thousand other machines validated, which is the average by age curve in green below):

HVAC Optimization, Now in its 4th patented generation called CryoGenX4, was validated in two stores. Total system efficiency across all five units improved by an average of 29%, while the EER across...
Summary Results The demonstration was a success as the units now provide colder supply air with greater efficiency due to the restoration of the heat transfer ability of the evaporator and condenser...
