16 Jul Transform Your Guestroom Fan Coil Units into State of the Art Energy Savers

As seen in Green Lodging News:

AirRevive provides the hospitality industry with an affordable, energy efficient alternative to replacement units.

AirRevive Re-commissioning Service

 

Ownership and management save time and money while contributing to sustainability initiatives.

  • Reduce FCU energy usage by up to 80%. View AirRevive project results.
  • Spend less; AirRevive is a fraction of the cost of replacements.
  • Avoid discarding hundreds to thousands of units.
  • Receive energy rebates and incentives.
  • Minimize A/C related service calls.
  • Extend the life of the asset.
  • Receive service when you need it; AirRevive works in operating hotels turning rooms over within 24 hours.
  • Proactive approach to guestroom renovations: avoid A/C related costs and customer service complaints resulting from renovation contamination.

 

Significantly improve guest comfort. 

  • Reduce A/C related noise to the sound of a whisper.
  • Lower humidity to under 66%, creating a dry, comfortable environment.
  • Attain temperature set points quickly.
  • Improve indoor air quality with fresh, crisp air and eliminate A/C related odors.

 

AirRevive conducted a case study comparing a fan coil unit’s performance with a PSC motor vs. an EC motor.

The blue line in the chart below represents  guestroom humidity measured before AirRevive service. The orange line represents humidity after  AirRevive refurbishment and re-commissioning.

Relative humidity below 66% signifies dry air.

The unit retrofit with an EC motor maintained guestroom relative humidity at or below 65%.

How?

 

AirRevive’s custom refurbishment solutions integrate proprietary cleaning technology with highly focused part and component replacement. AirRevive’s refurbishment process results in:

  • Coil temperature reduction; and
  • Optimized airflow.

This combination prepares the unit to be retrofit with an electronic commutation motor (EC motor).

 

AirRevive collected data measuring the performance of 164 fan coil units before AirRevive service and after AirRevive refurbishment and re-commissioning. 

The red line on the chart below represents the units’ airflow before AirRevive services demonstrating little to no airflow. The blue line represents the units’ airflow after AirRevive services. All units were brought back to the manufacturer’s specification of 450 CFM.

 

Hotel airflow before and after

The red line represents the units’ coil temperature before AirRevive services. The blue line represents coil temperature after AirRevive refurbishment and re-commissioning.

  • Coil temperature dropped by an average 4.5 degrees from 51.5 degrees to 47 degrees
  • 73% of coil temperatures at or below 49.9 degrees

AirRevive coil temperature comparison

 

 

The EC motor is programmed when the coil is working at maximum operating efficiency. This combination of optimized airflow and lower coil temperature makes AirRevive the proven best practice to retrofit EC motors.

 

AirRevive conducted a case study comparing a guestroom fan coil unit’s performance when an EC motor was retrofit into a unit with an impacted coil vs. a unit after AirRevive refurbishment – rejuvenated coil.

The graph below represents wattage in both scenarios.  Watts were reduced by 38% when the EC motor was retrofit into an AirRevive rejuvenated coil compared to an EC motor on a dirty coil. Click to view the complete case study.
