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.

The aeration system is for aeration and/or mixing of water, which system has at least one aeration unit that has a pump/propeller inside a feed pipe. The feed pipe, to which the water to be aerated, is sucked from beneath. The aeration system has the feed pipe expanding in the upper part of the aeration unit to a conical space working as a nozzle, via which the water continues its way to at least one annular opening.

Apparatus and method for aeration/mixing of water

A method and device for removing, from liquid such as water, dissolved volatile substances and gases when water is being distilled or evaporated. Feed water of a distilling apparatus or evaporator is heated to a sufficiently high temperature, whereby part of the feed water changes into vapor, and is then conducted to a purifying device. The feed water is discharged in the purifying device in the form of a thin film. The gaseous substances present in the feed water or liquid are separated by a separator device provided in the purifying device, and then conducted away through a connector provided on the purifying device.

Removal of dissolved volatile impurities from liquid

A procedure and apparatus for generating steam for an autoclave or an equivalent device, so that the load of the autoclave or device can be equalized. Thermal energy is stored in water under pressure which is converted when needed into steam which, in turn, is accumulated and later purified. The present invention also concerns the use of the procedure and apparatus to equalize load in the autoclave or device.

Generation and accumulation of steam

A column construction or boiling space in a distilling apparatus, having a pure vapor input connector, an input connector for water to be distilled, numerous heat exchange tubes within the column construction, a pure vapor removal connector, a condensate removal connector, and a connector for removing water to be distilled that has not vaporized. Pure steam is disposed to flow through heat exchange tubes, while impure water to be distilled is disposed to flow through an intermediate space between the heat exchange tubes. The heat exchange tubes are, at both ends, joined to flanges.

Distilling apparatus

A pure steam generator having a feed line for conducting feed water thereinto, a heating steam input for conducting heating steam thereinto, and a heat exchange apparatus therein for providing heat exchange between the heating steam and the feed water. A pure steam output is also provided, with a separation space being located in a lower portion of the pure steam generator, along with a centrifugal separator through which the pure steam flows from the separation space to the pure steam output. The pure steam output communicates through a circulation line with the pure steam generator for circulating pure steam from the pure steam output to the pure steam generator. The circulation line is preferably arranged to feed a mixing space, in which the feed water and the circulating pure steam are mixed.

Pure steam generator

Distillation apparatus is disclosed which operates according to the so-called thermocompressor principle and which incorporates tubular means disposed within the apparatus to define an inner conduit and an outer annular flow duct, means for dividing the outer annular flow duct into an upper portion and a lower portion, and aperture means provided in one of these portions of the divided annular flow duct. Energy imparting means, preferably blower means, is disposed within the housing of the apparatus such that after a fluid stream, composed of at least one of liquid to be distilled and vapor, flows through at least one heat exchange tube within the apparatus and through the inner conduit, vapor flows through the energy imparting means which conveys the same into one of the two portions of the divided annular flow duct, whereby the vapor discharges from the annular flow duct to be condensed.

Distilling apparatus operating on the thermocompressor principle

Distillation apparatus is disclosed which operates according to the so-called thermocompressor principle and comprises a housing in which a boiling chamber is situated to accommodate the liquid to be distilled, a heating device for heating the liquid to be distilled in the boiling chamber, a feed line for conducting the liquid to be distilled into the boiling chamber, an output line for removing the distillate from the distillation apparatus, and apparatus for imparting additional energy to the vapor that is produced from the liquid to be distilled in the boiling chamber such that the temperature of the vapor on the output side of the energy imparting apparatus is increased. According to the invention, at least one heat exchange tube is provided within the distillation apparatus through which a mixture composed of the liquid to be distilled and of the vapor produced therefrom is adapted to flow. A droplet separator is provided which defines a gush or overflow gap between it and the boiling chamber and through which the liquid-vapor mixture discharging from the heat exchange tube flows whereupon the vapor flows through the droplet separator to the apparatus for imparting additional energy thereto and which is constituted by a blower disposed within the distillation apparatus. Preferably, the heat exchange tubes are disposed around the boiling chamber and extend through a vapor condensation chamber.
