Patent ID: 8826676

Claim:
A system for regulating a climate of a greenhouse by means of cooling water, comprising: a condenser in operative engagement with a closed greenhouse, the greenhouse having warm air disposed within the greenhouse, the warm air being isolated from outside air disposed outside the greenhouse so that no outside air is being let in through ventilation doors or blown into the greenhouse, pipe means in fluid communication with the condenser for leading cooling water to the condenser, delivering means connected to the pipe means for delivering the cooling water into the condenser to exchange heat between the warm air and the cooling water to cool the warm air and to condense humidity in the warm air into water, the condenser having an outlet defined within the condenser to lead out overflow water from the condenser, the outlet being in operative engagement with the condenser and having a conduit connected to the condenser, the conduit having conduit means for removing the overflow water from the condenser without re-circulating the overflow water back to the condenser, a pump in operative engagement with the condenser to lead a main part of water collected in the pump from the condenser back for circulation to the pipe means, a blower in operative engagement with the condenser having blowing means for blowing warm air from the greenhouse, to be cooled down, into the condenser, and means for introducing carbon dioxide into the greenhouse.
