The system is for regulating the climate of the greenhouse. The warm greenhouse air is cooled by cooling water. The system has a spray condenser that includes a conduit for leading the cooling water to the condenser. The condenser has a blower to transfer warm air to be cooled to the condenser. The warm air from the greenhouse is used to warm the water sprayed from the spray condenser. The cooling water may be delivered from an evaporator that has water that is cooled by outside air blown into the evaporator.
