Proper ventilation of the refrigerator can also be
achieved by lower air intake aperture in the floor
and upper roof exhaust vent (see Fig. 7). A flue
has to be provided between the top edge of the
refrigerator and the roof ventilation which
directs the hot air and the exhausts straight to
the air vent in the roof.
The floor opening must have a cross section of
at least 250 cm² . Protect the opening, e.g. with
a baffle plate and a net, to prevent dirt from
entering the gas burner. Compared to side ven-
tilation, this ventilation method can allow more
dirt to enter the rear area of the refrigerator,
which makes regular maintenance of the gas
burner, at least once a year, necessary.
With this installation method, regular main-
tenance of the gas burner is only possible
once the device has been dismantled. It is
imperative that the refrigerator be installed in
a way to allow easy removal.
We therefore recommend providing an ade-
quate access opening (service flap) for ready
serviceability from the outside.
4.1.2 Side installation with floor-roof
ventilation
Another unfavourable method of rear installation
is to install the air intake and exhaust grilles (Fig.
10) at the side wall of the recreation vehicle. The
air-heat recirculation is very restricted which
means that heat exchangers (condenser, absor-
ber) cannot be adequately cooled. The optional
method of an additional air vent grille installed in
the floor also exhibits an insufficient air flow
duct.
4.1.3 Rear installation
Rear installation often causes an unfavourable
installation arrangement, as ideal ventilation
cannot always be assured (e.g. the lower venti-
lation grille is covered by the bumper or the rear
lights of the vehicle!) (Fig. 8). The maximum coo-
ling performance of the aggregate is actually not
available.
