The re-commissioned unit consumes the equivalent of $84 less energy annually, approximately $58,800 in total!
In the graph below, the AirRevive re-commissioned unit in room 932 is represented in blue.
The AirRevive re-commissioned unit’s averaged fan amps, when the unit was operating fan amps, was 1.5 amps.
The slip-in unit in room 933 is represented in red.
The slip in unit’s averaged fan amps, when the unit was operating fan amps, was 4 amps.

The manufactured unit represented in red produced guest room temperature demonstrates a wide band fluctuating between 60 and 74 degrees. It can be concluded the low temperature points on the bands represent a ramp up of very cold air before settling to the intended temperature set.
The AirRevive re-commissioned unit represented in blue produced guest room temperatures that fluctuated narrowly between 65 and 73 degrees. It can be concluded the accurate temperature set is reached quickly maintaining a comfortable guest room environment and using less energy.
The data demonstrates the re-commissioned unit maintained guest room temperature with a 6 degree variance while the slip-in unit produced guest room temperature with a 14 degree variance.
