AIR CONDITIONING AND VENTILATING UNITS COVER

Abstract: The air conditioning and ventilating units cover according to the present invention consist of the external element (1) formed from uniform plate into the U profile in the cross-section and connected disconnectedly internal element (2) made of uniform plate in the similar to the external element shape. The impression of the external element (1) gives side edges surfaces (3) after forming shape with cross-section similar to U. The side edges of internal element (2) has collar ends (4) for fish joint with side edges planes (3) of external element (1). In the space between external (1) and internal element (2) is placed thermoinsulation material (5). On the frontal side of external element (1) is disconnectedly mounted diaphragm or shielding plate (6) and removable shielding plate (7) on the inspection side. Inside the cover from the inside element side could be for example mounted fan (8) and heat exchanger (9).

Description: Air conditioning and ventilating units cover The object of the present invention is air conditioning and ventilating units cover especially useful for small and medium units. In the present state of the technology generally known and used air conditioning and ventilating units cowers are made in form of set of separate metal panels mounted to the frame by disconnecting bolt joints. Examples of such solution are air conditioning and ventilation units manufactured by German companies like: WOLF Klimatechnik or AL-KO THERM GmbH. There are also known air conditioning and ventilation units cover solutions in which separate metal panels are formed in such way that, after completion and joining by bolts, forms the self-supporting structure. Such solutions are used in the air conditioning and ventilation units manufactured by German company GES Happel or by Franch company Seven Air. Inconvenience of the known solutions is, that spatial cover is divided into segment flat panels, that has disadvantageous influence on the strength performance of all cover, especially in the edge joints planes. Additionally separate panels joined by bolts, create necessity to use additional structural elements, rising the unit cover weight. Additional operation of bolting with help of special equipment makes montage and production technology more complicated, and also rising unit production cost. Big number of joint points creates bigger danger of corrosion centres creation in the joints, which reduce lifetime of the unit. The essence of the present invention is the construction of the air conditioning and ventilating units cover of thin metal walls consisted of external element formed from uniform plate into U - profile in cross-section and, joined by disconnecting joint, internal element made of uniform plate in the shape of external element profile. The impression of the external element gives after forming side edges surfaces shape with cross-section similar to U. The side edges of internal element has collar ends for fish joint with side edges planes of external element. In the space between internal and external element is placed thermoinsulation material. On the frontal side of external element is removable mounted diaphragm/shielding plate and shielding plate on the inspection side. In the solution according to the present invention the cover solution of external element and removable joined internal element, both made of uniform plates formed in the U profile in the cross-section, permitted obtaining of structurally and materially uniform spatial cover construction, giving it the high strength box construction character, without weakening in the joint planes and with rigidity obtained without special plane configuration. The important advantage of the cover according to the present invention is significant reduction of number of joining elements, which reduces construction weight, making montage technology easiest and opens a possibility of significant reduction of montage time and production cost and in the consequence the unit price. The significant advantage of the solution according to the present invention is ability to use it as modular cover construction of the air conditioning and ventilating units of different types and different functional units. That gives the solution markings of universal solution and make possible manufacturing the dimensional series of types of covers. Object of the present invention in the effect example are presented on the sample drawing on which on the fig.1 is presented axonometric view of the air conditioning and ventilating units cover, on the fig.2 were presented axonometric view of the basic cover construction consisted of joined together external and internal elements, on the fig.3 were presented - axonometric view of the external element, on the fig.4 were presented - axonometric view of the internal element, on the fig.5 were presented - axonometric view of the air conditioning and ventilating units cover with sample internally mounted fan and heat exchanger. The air conditioning and ventilating units cover according to the present invention consist of the external element 1 formed from uniform plate into the U profile in the cross-section and connected disconnectedly internal element 2 made of uniform plate in the similar to the external element shape. The impression of the external element 1 gives side edges surfaces 3 after forming shape with cross-section similar to U. The side edges of internal element 2 has collar ends 4 for fish joint with side edges planes 3 of external element 1. In the space between external and internal element 2 is placed thermoinsulation material 5. On the frontal side of external element 1 is disconnectedly mounted diaphragm or shielding plate 6. The removable shielding plate 7 on the inspection side is mounted. Inside the cover from the inside element side could be for example mounted fan 8 and heat exchanger 9.

Claims: What is claimed is: 1. The air conditioning and ventilating units cover of metallic thin wall construction consisted of external element (1) formed from the uniform plate into U shape profile in the cross-section and disconnectedly connected internal element (2) made of uniform plate in the shape similar to the external element (1) profile. At the same time external element (1) impression gives side edges (3) after forming cross-section profile shape similar to U, and side edges of the internal element (2) has collar edges (4) for fish joints with side edges surfaces (3) of external element (1). In the space between external (1) and internal element (2) where placed thermoinsulation material (5). 2. The cover according to the claim 1 , with disconnectedly mounted on the front surface of the external element (1) the diaphragm/shielding plate (6) and removable shielding plate (7) mounted from the inspection side.
