in the comforts of a RV. From campgrounds right on the beach to
restaurants that deliver pizza straight to motor homes, there's no
better way to see the USA.

RV Top 3 - RV Fridge - Netflix
Recreational vehicles (RVs) are designed to be self-sufficient, making
an on-board refrigerator a highly desirable appliance. However, RVs are
subject to conditions that make the design of their refrigerators quite
challenging. The main issues are vibrations, accelerations, the energy
required to drive the refrigeration process, and the often off-level
attitude of the vehicle, especially while in transit. An absorption-type
refrigerator overcomes most of these design challenges, and therefore
has been popular in RVs since the 1950s.
RV Top 3 - Absorber - Netflix
The absorber or absorber coils is where the fluids are recombined to
complete the refrigeration fluids circuit. The ammonia gas Q5 drops down
from the evaporator into the absorber where it comes into contact with
the weak solution Q2 (water) flowing into the top of the absorber coils.
When the ammonia vapor Q5 comes into contact with the weak solution
liquid Q2, the weak solution absorbs the ammonia gas due to ammonias
affinity for water. The absorption of ammonia gas into the water
solution is an exothermic process, thus heat needs to be rejected from
the absorber coils. The absorber coil is where the heat from within the
fridge is rejected into the surroundings.
