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.
The evaporator works the opposite of the condenser, here refrigerant liquid is converted to gas, absorbing heat from the air in the compartment. When the liquid refrigerant reaches the evaporator its pressure has been reduced, dissipating its heat content and making it much cooler than the fan air flowing around it. This causes the refrigerant to absorb heat from the warm air and reach its low boiling point rapidly.
