INQUIRIES ABOUT THE A/C UNIT
–
Inquiries to your Airxcel, Inc. representative or
to Airxcel, Inc. pertaining to product installation
should contain both the model and serial
numbers of the roof top unit. These roof top
heat pumps have model and serial number
identification in two locations : (1) The rating
plate sticker can be seen by removing the
upper unit outer plastic shroud, (2)
model/serial number sticker (silver color) is
located on the return air section of the
basepan of the roof top unit.
Additionally, a sticker is visible on the rear of
the plastic shroud with the Manufacturer Name
and Model Number.
II. HEAT PUMP SIZING
The ability of a heat pump in the cooling mode
to cool a vehicle or maintain a consumer
desired temperature is dependent on the heat
gain of the vehicle. The physical size, the
window area, the quality and amount of
insulation, the exposure to sunlight, the
number of people using the vehicle and the
outside temperature, may increase the heat
gain such that the capacity of the air
conditioner is exceeded.
As a general rule, air supplied (discharge air)
in the cooling mode will be 15 to 20 degrees F.
(8 to 12 degrees C) cooler
than the air
entering (return air) the ceiling assembly
bottom air grilles.
For example, if the air entering the heat pump
is 80 degrees F. (27 degrees C) (return air),
the supply air (discharge air) into the vehicle
will be 60 to 65 degrees F. (15 to 19 degrees
C). As long as this temperature difference (15
to 20 degrees F, 8 to 12 degrees C) is being
maintained, the unit is operating properly.
Again, give careful consideration to the vehicle
heat gain variables. During extreme outdoor
temperatures, the heat gain of the vehicle may
be reduced by:
➢
Parking the vehicle in a shaded area
➢
Keeping windows and doors closed
➢
Avoiding the use of heat producing
appliances
➢
Using window shades (blinds and/or
curtains)
For a more permanent solution to high heat
gain situations, additional vehicle insulation,
window awnings and/or window glass tinting
should be considered.
