Norcold NRF30 Convection Basics, Ventilation for Norcold Portable Refrigerator/Freezers, Storage

Convection Basics

When ventilating an enclosed space, consider the facts of natural convection, that cool air falls and warm air rises. The ideal ventilation design will use natural convection and provide a path for cool air to enter below the refrigerator/freezer and warmer air to exit above the refrigerator/freezer. The design of the refrigerator/freezer allows this to occur if there is

a ventilation opening above the refrigerator/freezer. The heat created by the refrigerator/ freezer can then flow freely out of the enclosed space rather than be trapped within it.

Ventilation for Norcold Portable Refrigerator/Freezers

For the maximum cooling efficiency and the lowest power
consumption, use the following guidelines. These are
especially important when using the refrigerator/freezer
under a counter or in an enclosed space.
-	Make sure that there are at least 4 inches (102 mm)	10	10
	of clearance [10] from the vents on each side of the
	compressor compartment (See Art02218).
-	When using the refrigerator/freezer in an enclosed
	space such as an RV basement, make sure that

there are at least 48 square inches (310 square	Art02218
cm) of ventilation area above the compressor
compartment. Less than 48 square inches
(310 square cm) of ventilation area will result in

poor refrigeration performance, continuous compressor operation, and a shortened refrigerator/freezer life.

- The ventilation area should open into the living area of the vehicle

Storage

When storing portable refrigerator/freezers, make sure that there are no obstructions (luggage, etc.) around the refrigerator/freezer while it is operating (See Art02219). Make sure that there is adequate ventilation space to the refrigerator/freezer. Locate the ventilation space in an area that allows natural convection through the refrigerator/freezer condenser coils and around the compressor.
