Product Introduction The AIRSYS FCB (Free Cooling Box) is one of several energy saving AIRSYS HVAC products
available to Verizon Wireless. The FCB system described in this document is a stand-alone
economizer that can be installed into a shelter configured with any existing 3rd
party HVAC
systems. When installed, the FCB takes master control over the existing HVAC system to
manage the environment for lowest cost operation.
The FCB has two key benefits:
1. Optimization of free air cooling Free Air Cooling Defined: Simply put, is using the outside air to cool a shelter instead of
running a compressor to cool. The AIRSYS FCB consumes 1% to 10% of the energy to cool
a site when compared to a compressor trying to cool the same site. There are some
limitations to the ability to Free Cool:
Outside temperature must be cooler than inside temperature. In fact the colder the outside air
the greater the cooling capacity of the FCB. As the outside air temperature warms up to the inside
air temperature the FCB will be unable to cool the site sufficiently to keep it with the set points
(77+2/-4°F). It is at this point the FCB will allow the existing HVAC system to provide cooling.
Relative Humidity in the shelter must stay below 85%. In order to prevent water vapor from
condensing on sensitive electronic equipment, the relative humidity inside the shelter is managed
by a humidity sensor that is part of the FCB control package.
Getting to the highest energy efficiency:
As stated above the FCB requires<10% of the energy consumed by a standard HVAC
system, to keep a site cool. As such the more the FCB can run the more energy is saved.
The AIRSYS FCB is designed to provide cooling benefit even when the outside temperature
is nearly equal to the inside temp. This is mostly due to the fact that the air being exhausted
at the site is extracted up higher, which is commonly much warmer air than the nominal
inside temperature. AIRSYS has years of experience optimizing their control schemes to
remove as much heat as possible while consuming the least amount of energy.
2. DC operation to preserve cooling during prime power outages. Shelters with no generator on site: The loss of prime power often means the loss of air
conditioning. Once the air conditioning is lost many sites will last 45 – 90 minutes before
shelter temperatures rise enough to cause critical equipment failures (>110 °F). If you have a
DC powered FCB installed the site can maintain temperature with a small additional load on
the DC reserve. Even if the outside temperatures are higher than the inside temperature, a
DC powered FCB will provide emergency ventilation to stave off the rise in site temp and
improve site reliability.

Physical Location of the FCB
Where on the shelter should the FCB be located?
FCB location is best if it can be located according to the drawing below:
Mounted on short side of the shelter so there is maximum Air flow
Centered on the wall to facilitate good air flow
With a minimum of 24“ clearance between supply vent and partial1 blockage
Do not place directly behind complete supply blockage suck as a battery bank.
1. Partial is referring to an open equipment rack whereby the space in the rack directly in front of the supply air
grill is at least 50% open.
