FIELD: cold production, particularly water cooling devices, which use low ambient temperature in autumn and winter period.
SUBSTANCE: device comprises heat-exchanger having heat-exchanging surface made as building roof part, distribution pipes installed on roof ridge and provided with orifices distributed along pipe lengths. Device also has drain pipes included in inner rain water drain system, water spillway riser, receiving vessel and accumulation vessel located in floor depression. Receiving vessel comprises overflow partition, overflow pipe and electromagnetic valve. Accumulation vessel has pump for water delivery into distribution pipes and control means, which automatically controls electromagnetic valve in dependence of water level inside vessel.
EFFECT: simplified structure, decreased cold production costs and increased performance.
