FIELD: distillation processes, sea water desalination, etc. SUBSTANCE: vapor-compression plant has body, forced-draught fan, preliminary heat exchangers and reflux condenser made in form of membranes connected in pairs. Each pair of membranes may be simultaneously disconnected from reflux condenser for replacement. Membranes pair is made, mainly, from polymeric material. Membranes freely hangs down in reflux condenser. Condenser chamber is formed inside each pair, and evaporator chamber, in space between membrane pairs. EFFECT: higher efficiency. 9 cl, 5 dwg
