In cosmetics, the most common use of acetone is in nail polish remover. Acetone is a colorless, flammable liquid that evaporates easily. It is an organic compound because carbon atoms are present in acetone's chemical formula, which is (CH3)2O.
Swenson thermal vapor recompression (TVR) evaporators use a thermocompressor to reduce the steam required per pound of evaporation. To reduce energy consumption, water vapor from an evaporator is entrained and compressed with high pressure steam in a thermocompressor so it can be condensed in the evaporator heat exchanger. The resultant pressure is intermediate to that of the motive steam and the water vapor.
Evaporative coolers draw hot air from outside through a series of wet filter pads that are supplied with water from a tank at the base of the unit. Water from the filter pads evaporates, drawing heat out of the air and humidifying it. The cooled, moist air is then blown through the house. Evaporative coolers work partly by cooling the air inside the house and partly by creating a cooling breeze.
