Window Freezer & Air Cooler

IceFAC.com

Freezes water at night and uses the ice to cool indoor air during hot summer days.

This process saves energy by taking advantage of the temperature difference between day and night.  It also uses electricity during off-peak hours at night to freeze water.

The 3 images above, display an icebox sitting on top of a window refrigerator-freezer with the back of the refrigerator-freezer (its condenser) exposed to the outdoors. A cone shaped heat exchanger (a cone shaped hole for air passage) is inside the icebox. The vertical lines are copper pipes containing water-ice to cool the air passing through the cone inside the icebox.  The blue square is an air fan blowing hot outdoor air into the cone shaped hole inside the icebox. The cone shaped hole in the icebox acts as a heat exchanger. At night when temperature is cooler than day, the freezer freezes the ice in the icebox.  During the hot days, the air fan (blue) blows hot air through the hole into the insulated icebox (heat exchanger). Cold air then exits the cone shaped hole and enters the home, cooling indoor space.

Great for Studios, Homes, Offices, RVs, Dorms, Motels, Show Rooms, Factory Floors 

Benefits:

* Saves indoor space. It uses the rarely used space on top of the fridge-freezer (for cooling air) , or under the window A/C (for fridge-freezer).

* 2 synergistic green devices (Air Cooler & Fridge-Freezer) in one that is used all year (not just during hot summer days).

* It can cool indoor air faster than conventional window or portable AC. See 2 Min. Video
       A larger, detachable, external fan and heat exchanger, helps it cool indoor air faster.

* The hotter it gets, the faster it cools. Its cooling power (efficiency) increases at higher indoor temperatures.

* Dehumidifies indoor air.

* Circulates Indoor Air. It transfers heat from indoor to the icebox, melting the ice.

* True Portability:  During the hot days, while cooling indoor air, it can be detached from the window.

*   It does not have an internal fan coil which reduces manufacturing cost, prevents dust & mold built-up inside the unit,  reduces indoor air pollution.

* Saves Energy by taking advantage of the temperature difference between day & night and using electricity during off-peak hours at night to freeze water.

* To save energy or reduce the size of water-ice reservoir, instead of water, it can use other phase change material.
