DESCRIPTION:
BRIEF SUMMARY
The invention concerns an air conditioning/treatment installation with centrifugal sprayers.
On certain premises, the hygrometry and temperature have to be kept within values compatible with specific utilization of the premises, whatever the outside environmental conditions, as it is the case in buildings equipped with a collective air conditioning installation, certain stores or warehouses, greenhouses and breeding/rearing buildings.
Particularly in greenhouses, rather strictly controlled relative humidity and temperature conditions have to be maintained which, combined with periodic, well-adapted waterings and treatments, enable obtaining maximum production output. In this area, it may be profitable (in order to restrict investment costs) to also use the hygrometric control installation to ensure periodic phytosanitary treatment of the plants, or even to ensure watering.
Certain means are already available to ensure constant hygrometry in greenhouses:
A device consisting of a rotary disk, notched on its periphery and which receives in its center the liquid then sprayed in the form of a thinner and thinner film towards the disk periphery. The peripheral notches create cyclic cut-outs of the fluid film. The particle dimension decreases as a function of the rotary speed of the disk.
A device which combines air and water: water is sprayed by compressed air in a spray nozzle.
Pressurized water installations, which ensure very thin spraying by means of jet pipes of a very small section.
Ultrasonic division, by very fast compressed air passage through a special chamber, supplied with a fluid: this causes the fluid scattering into fine particles.
All the above devices are rather fragile, use a lot of power, are rather susceptible to scaling and clogging and in certain cases, do not allow for the required spraying fineness.
The present invention is designed to remedy such problems. The invention as defined in the patent claims enables meeting the requirement to develop an air conditioning installation capable of maintaining humidity and temperature within a well-defined range, and allowing for the distribution of phytosanitary, nutritional, antiseptic or other products.
This air conditioning installation (with centrifugal sprayers) is mainly characterized by its components: it consists of centrifugal sprayers, each provided with a deflector the shape and slant of which are a function of the area to be covered. The sprayers are hydraulically connected to a loop circuit incorporating a buffer reservoir (supplied with liquid), a centrifugal purifier, a self-cleaning filter, a pump, individual flow regulating devices, a collective flow regulating electro-valve controlled by a regulation device (which is servo-controlled by a temperature sensor and a hygrometry sensor). The driving motors for the sprayers are power supplied through an adjustable frequency inverter.
The deflectors (fitted to the sprayers) present themselves in the form of a flat corolla (which may be concave or convex-shaped), secured to the base of the driving motor and making an angle a (75.degree. to 90.degree.) with respect to the motor shaft axis. The external edge of the deflectors is circular, elliptical or rectangular shape. The internal edge of the deflectors provides an opening around the base of the driving motors, with a passage section of approximately 1.5 times that of the centrifugal spraying head.
The larger deflector dimension is approximately three times the outer diameter of the centrifugal spraying heads, while the opening diameter roughly matches 1.5 times the outer diameter of the heads.
The internal edge of the deflectors is equipped with an annular gutter, for drippings recovery and recycling through a duct (which is connected to the centrifugal sprayer hydraulic supply line).
The centrifugal spraying head is topped by a fixed disk, at an adjustable distance from the upper edge of the centrifugal spraying head. The distance X of the fixed disk with respect to the deflector opening roughly matches one quarter of the spraying head
