General Description
The Marvair
®
ComPac
®
I and ComPac
®
II air
conditioners are used primarily to cool electronic and
communication equipment shelters. Due to the high
internal heat load, these shelters require cooling even
when outside temperatures drop below 60°F (15°C).
The ComPac I and ComPac II air conditioners have the
necessary controls and components for operation during
these (less than 60°F [15°C]) temperatures. All models
use the non-ozone depleting R-410A refrigerant.
The primary difference between the ComPac I and the
ComPac II units is that the ComPac
®
II air conditioner
has a factory installed economizer. When cool and dry,
the economizer uses outside air to cool the shelter. The
economizer provides temperature control, energy cost
savings, and increased reliability by decreasing the
operating hours of the compressor and the condenser
fan. The ComPac I and ComPac II air conditioners are
problem solvers for a wide range of conditions and
applications. To insure proper operation and optimum
performance, all economizers are non-removable,
factory installed and tested. In addition, factory and
field installed accessories can be used to meet specific
requirements.
The HVEA and HVESA models are Marvair’s most efficient wall mount air conditioners.
Electronically commutated outdoor fan motors combined with highly efficient scroll
compressors result in Energy Efficiency Ratios (EER’s) of up to 11.75.
Models HVESA36-42-49-60 have a 2-stage compressor with first stage cooling
approximately 65% of the total cooling capacity. The 2-stage compressor provides lower
start-up amps which can be critical when operating with a generator. The two stage
compressor can also reduce energy costs and is able to more precisely match the cooling
capacity of the air conditioner with the heat load in the shelter. Both ComPac I and ComPac
II units are available with 2 stage compressors.
Safety Listed and Energy Certified
All ComPac air conditioners are built to UL standard 1995, 2nd edition and CAN/CSA
C22, No. 236-5, 2nd edition. For energy efficiency and performance, the units are tested
and rated in accordance to the ANSI/ARI (Air-Conditioning and Refrigeration Institute)
Standard 390- 2003 (Single Package Vertical Units). All units meet or exceed the efficiency
requirements of ANSI/ASHRAE/IESNA 90.1.2007. The ComPac I and ComPac II air
conditioners are commercial units and are not intended for use in residential applications.
