It uses the temperature difference between day & night; freezes water at night and lets it melt during day to cool the fridge & indoor space (saving electricity).  It's a great energy efficient, synergistic, multi-functional, quiet appliance for home, office or apartment, saving electricity and indoor space all year round.  Another unique feature is that to save electricity, during hot summer, the user can reduce the cooling space inside the refrigerator.  For cooling, it uses latent heat of melting ice to water (80 calories/gram). It also uses some latent heat of vaporization of water (540 calories/gram) depending on indoor humidity level.

Like a window A/C, the condenser (back) of the window refrigerator is outdoors. A refrigerator may also be added to a thru-the-wall A/C or heat pump (very common in hotels, office buildings and rental units) commonly installed under the window through an opening in the wall.


Unique Features, Advantages & Benefits:
red  Saves Electricity: Up to 80% during winter & cold nights.  Up to 70% during fall, spring & summer

red  Less Expensive:  When combined with a heat pump, cooler or A/C; it's one quiet, energy efficient, synergistic, multi-functional appliance that costs less to buy and maintain, weighs less, takes less space & uses less electricity than the above appliances bought separately.  
red  Refrigerator's internal size can change: To save electricity, during hot summer, the user can reduce the cooling area inside the refrigerator.  
red  Quieter:  Its condenser is outdoors
red  Humidifies:  During summer it cools & humidifies indoor space
red  Has direct access to solar & wind energy:  Its condenser (back) is outdoors


For seasonal energy saving features click on the links below:  

1.  Summer, Fall/Spring/Night  By freezing water at night when it's colder outdoors.  It allows the ice to melt during day when it's warmer outdoors.    

2.  Fall/Spring/Night (Mild)   whenever outdoors is colder than the kitchen (see example below).
3.  Winter  By letting cold outdoor air into the refrigerator/freezer. 


Example:  When the outdoor temperature is 80 °F, the window A/C consumes less electricity than when the outdoor temperature is 100 °F. The same is true of a window refrigerator. When outdoor temperature is 60 °F,  50 °F,  40 °F or 30 °F, the window refrigerator uses less electricity than a similar indoor refrigerator that is in a 70 °F or 80 °F kitchen day and night all year round.    


According to Energy Information Administration's 2001 official energy statistics Table, refrigerators consumed 13.7% (156 billion kWh), freezers 3.5%, lighting 8.8% and TVs 2.9%. Every home has at least one refrigerator/freezer and it's never turned off.
