General Description

The Marvair

Classic wall mounted heat pumps are the ideal HVAC system

for a wide variety of applications. The exterior mounting means that no

valuable interior space is required. The Classic heat pumps are packaged

units – the refrigerant piping and internal wiring are factory assembled

and thoroughly tested. All components are readily accessible for easy

service and maintenance. The energy efficient operation keeps operating

costs to a minimum and makes the Marvair heat pumps ideal problem

solvers for a wide variety of applications, including offices, classrooms and

telecommunication shelters.

Three Series to meet any Budget or Efficiency Requirement - Three

series of Classic heat pumps are available. The Classic HVPA models are

our most efficient models and feature EERs (Energy Efficiency Ratio) of up

to 11.50. No wall mount heat pump is more efficient. The HVPSA models

feature a 2-stage compressor that matches the cooling capacity to the

heat load. Our AVPA models have EERs of up to 9.75. The AVPA & HVPA

(single stage compressor units) are built in nominal cooling capacities of

2, 2½, 3, 3½, 4 and 5 tons. The HVPSA (2-stage compressor) units are

available in nominal cooling capacities of 3, 3½, 4 and 5 tons.

Outside Air for Ventilation or Free Cooling

- A full range of accessories and options allows the Classic

heat pumps to be optimized for each application. For classrooms, a complete range of ventilation

options are available to meet the fresh air requirements of the ASHRAE 62 standard, “Ventilation

for Acceptable Indoor Air Quality”, including the exclusive Marvair GreenWheel

Energy Recovery

Ventilator. Where cooling is required during cool or cold weather, e.g., telecommunications shelters, a

factory installed economizer should be used. To insure proper operation and optimum performance, all

outside air ventilation packages are non-removable, factory installed and factory calibrated.

2-Stage Compressor -The HVPSA models feature a two stage compressor with a first stage capacity

of 65% of the total capacity. The two stage compressor offers better comfort by maintaining more

precise temperature and relative humidity levels with improved overall energy efficiency. During mild

days, the first stage can satisfy the load, minimizing temperature fluctuations providing steady, even

comfort. With Integrated Part Load Performance Values (IPLV) of up to 15.0, the Classic heat pump

with the two stage, high efficiency compressor can provide significant energy savings compared to

older, less efficient systems. The cooling mode has two stage operation; heating is single stage.

Quiet in the Classroom - In addition to high efficiency, the HVPA and HVPSA models minimize sound

levels in the classroom. A high efficiency axial fan moves air silently through the outdoor

coils. A low vibration, scroll compressor insures quiet operation as well as energy efficiency.

The indoor air mover utilizes a revolutionary electronically commutated motor (ECM). This

motor consumes a minimum of power with whisper quiet operation. The ECM automatically

adjusts its speed to maintain the proper air flow at various external static pressures.

Safety Listed and Energy Certified - All Classic heat pumps are built to UL standard 1995, 4th

edition and CAN/CSA C22.2, No. 236-11, 2nd edition. For energy efficiency and performance, the

units are tested and rated in accordance to the ANSI/AHRI (Air-Conditioning Heating and Refrigeration

Institute) Standard 390 (Single Package Vertical Units). All units meet or exceed the efficiency

requirements of ANSI/ASHRAE/IESNA 90.1.2007. The Classic heat pumps are commercial units and

are not intended for use in residential applications.

Dehumidification - The introduction of outside air can cause humidity levels to rise to unacceptable

levels. To reduce humidity, the Classic heat pumps can be ordered with a Hot Gas Reheat (HGR) coil.

The HGR coil allows the heat pump to dehumidify without adversely lowering the temperature in the

classroom and uses less energy than electric reheat. When used in conjunction with the GreenWheel

ERV, humidity levels can be controlled at a minimum of expense. See page 4 for a detailed description

of the operation of the Hot Gas Reheat Coil.
