ODESSA, FLA.—Hasek Communications, the Odessa, Fla.-based publisher of Green Lodging News, has added an AirRevive case study to its website. The case study details the successful refurbishing and re-commissioning of 167 fan coils at a Marriott hotel—a process that took 21 days.
The hotel that runs at 98 percent occupancy year round needed to upgrade or replace their guestroom fan coil units. The units were not properly operating to cool and heat. This resulted in guestroom complaints, reduced guest satisfaction and the consumption of more energy for less return. The challenge for this airport property was the property could not give up guestrooms. The age of the property and the fan coil units was also a challenge.
The property’s flagship, Marriott, engaged AirRevive to explore an alternative to replacement fan coil units.
Built in 1984, the two buildings that consist of 167 guestrooms are equipped with Unilux vertical fan coil units. The guestroom units are supplied by central chilled water and hot water.
Most Units Were Not Operating Properly
AirRevive conducted a site survey. AirRevive determined 84 percent of the guestroom fan coil units were not operating as designed.
The case study details how the fan coil units were brought back to their original operating performance level through valve replacement, coil rejuvenation, upgraded insulation, and EC motor retrofits. Graphs illustrate improved performance levels.
The project resulted in the fan coil units operating “as new”. The re-commissioning enhanced the units’ operation to perform better than new by:
• Consuming up to 60 percent less energy;
• Maintaining guestroom temperature within narrow band; and
• Cooling the guestrooms within minutes and maintaining temperature set point.
