Abstract:
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.

Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
A system for drying and cooling greenhouse air, the system comprising water distribution means (1), by means of which water cooler than the dewpoint temperature of the greenhouse can be sprayed directly into its the air space without separate condenser chambers, structures and fans.
Abstract:
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.
Abstract:
Methods and systems are disclosed which make use of undulating motion imparted to a body which is situated in a fluid. The body and the fluid have with respect to the other a relative flow in a given direction, and the configuration of the body in the fluid is such that the body generates Karman vortices in the fluid, the body being supported in such a way that these vortices result in undulating motion of the body in the fluid. This undulating motion is made use of in a number of different ways.
