The invention relates to a device for controlling the climate in a greenhouse, comprising a first heat exchanger (7) with a first series of channels (7a) and a second series of channels (7b), greenhouse supply means (1) leading from the greenhouse to the first series of channels, outside supply means (5) leading from outside to the second series of channels, greenhouse discharge means (4) leading from the device to the greenhouse and outside discharge means (6) leading from the device to the outside, wherein the greenhouse discharge means connect to the first series of channels and the outside discharge means connect to the second series of channels. The air is hereby retained in the greenhouse without supply of new air, while the temperature of the air in the greenhouse can be adjusted while maintaining a separation between greenhouse air and outside air.

Device for Climate Control of Greenhouses

The system (1) and method are for the cooling and dehumidification of a space (4) within an enclosed area and are provided with a first air/dry medium or air/water heat exchanger (6) for the cooling of dry medium or water by ambient air and a second air/dry medium or air/water heat exchanger (26) connected with the first heat exchanger for the receipt of dry medium or water. The second air/dry medium or air/water heat exchanger is provided with an air inlet which runs from the enclosed space and a cooled air outlet which runs to the enclosed space. Heat and vapor are withrawn without ventilation from the enclosed space.

System and method are for cooling and dehumidification of space within enclosed area

Process and device for concentrating saline water 12 with a view to an industrial production of the inorganic salts present in the latter. According to the invention the initial saline water 12 is delivered by pumping 20, 22 to a spraying device 24 arranged at a height, which sprays the saline water in the form of rain into a column of air 26 whose relative moisture is lower than the relative moisture existing at the surface of the concentrated saline water 14 collected. In addition, a mixing ratio of the sprayed saline water to the air is chosen such that the quantity of heat present in the droplets is much smaller than that present in the air (for example 0.02). The invention is intended especially for industrial production of potassium hydroxide from an appropriate saline water.
