FIELD: equipment for production of purified fresh water; applicable in agriculture and industry and in household conditions. SUBSTANCE: vacuum plant has heat exchanger-condenser in form of vacuum vessel communicated with vessel for water. In water spraying, it evaporates under effect of deep vacuum in vessel and cools it. Damp air condenses on external surface of condenser-heat exchanger. There are drip pan, receiving, hollow for water catcher. EFFECT: reduced power input and cost of produced fresh water. 1 dwg
