A defrost timer taken out of a household refrigerator. The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. [1] The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer.
A refrigerator with a crisper drawer at the bottom of its main compartment Open crisper drawers. A crisper drawer (also known as a crisper) is a compartment within a refrigerator designed to prolong the freshness of stored produce. Crisper drawers have a different level of humidity from the rest of the refrigerator, optimizing freshness in ...
An energy tower (also known as a downdraft energy tower, because the air flows down the tower) is a tall (1,000 meters) and wide (400 meters) hollow cylinder with a water spray system at the top. Pumps lift the water to the top of the tower and then spray the water inside the tower. Evaporation of water cools the hot, dry air hovering at the top.

If the water flow velocity is below the rising velocity of air bubbles, then water trickles down to the low point Lo2 and traps the remaining air between Hi1 and Lo2. As more water flows down, the upward leg Lo2 to Hi2 fills up. This exerts a pressure on the trapped air of either H2 m of water (WG = water gauge) or H1, whichever is less.
The Einstein–Szilard or Einstein refrigerator is an absorption refrigerator which has no moving parts, operates at constant pressure, and requires only a heat source to operate. It was jointly invented in 1926 by Albert Einstein and his former student Leó Szilárd , who patented it in the U.S. on November 11, 1930 ( U.S. patent 1,781,541 ).
