History
While the Crosley Icy ball refrigerator is no longer sold or manufactured, absorption cycle refrigeration is still in use. In addition to RV applications, ammonia cycle refrigerators are still used in developing countries. These are also batch-cycle devices, but incorporate various condensers, check valves, integral kerosene burner, etc., so that the disassembly and tub of water required to regenerate the Icy Ball are no longer needed. Ammonia refrigeration is also used in large industrial applications, where its efficiency more than compensates for the higher initial cost, and associated risk. Though it was once fairly popular for home air conditioning, concerns related to ammonia leakage have caused mechanical refrigeration to dominate that market.

Famous quotes containing the word history:
“The history of philosophy is to a great extent that of a certain clash of human temperaments.”
—William James (1842–1910)
“Let us not underrate the value of a fact; it will one day flower in a truth. It is astonishing how few facts of importance are added in a century to the natural history of any animal. The natural history of man himself is still being gradually written.”
—Henry David Thoreau (1817–1862)
“Hence poetry is something more philosophic and of graver import than history, since its statements are rather of the nature of universals, whereas those of history are singulars.”
—Aristotle (384–322 B.C.)
