Definitions

• the present invention relates to a single-block wall-mounted air conditioner
• a condenser unit traversed by a main flow of outside air between an input section and an output section, which are in communication with the exterior
• an evaporator unit traversed by a flow of air internal to the space to be conditioned, which unit comprises a fan positioned with the inlet in front of an evaporator.
• the conditioner can be wall mounted so that said input section and said output section can be set to coincide with appropriate holes for communication with the exterior, obtained in the wall.
• the disposition of the conveying grid through which the cooled (and dehumidified) air is reinserted into the space changes: if the position is low, the grid must be located in the upper part of the conditioner, if it is high, the grid must be located in the lower part of the conditioner.
• the prior art provides the traditional solution of building two distinct apparatuses: one structured for low positioning, the other one structured for high positioning.
• the main aim of the present invention is to provide a single-block conditioner equipped with a single structure, comprising a condenser unit and an evaporator unit set side by side, able to be adapted indifferently for low or high positioning.
• a sure advantage of the invention is its structural simplicity.
• Another advantage of the invention is represented by its ability to enable the achievement, in a simple manner, of an effective air renewal in the interior space in which the conditioner is installed and operating.
• Figure 1 shows a schematic section drawn according to a horizontal median plane
• Figure 2 shows, in enlarged scale, a schematic section of the evaporator unit 3 drawn according to a vertical median plane;
• Figure 3 schematically shows the possible positions of the invention in a space
• Figure 4 shows a schematic exploded perspective view.
• the reference number 1 indicates a single-block air conditioner apparatus comprising a condenser unit 2, traversed by a main flow of external air between an input section 21 and an output section 22, and an evaporator unit 3, traversed by a flow of air internal to the space to be conditioned, which, in turn, comprises a fan 31 positioned with the inlet in front of an evaporator 62.
• the condenser unit 2 and the evaporator unit 3 are set side by side and are enclosed in a single rigid case or cover 4.
• the condenser unit 2 comprises a chamber 23 which is in communication with the exterior through said input section 21 and output section 22.
• a mouth 24 able to place in communication said internal space with the chamber 23.
• the mouth 24 is provided with closure organs (25) whose activation is controlled in a motorised manner by an external remote control set not shown herein and, by placing the internal space to be condition in communication, it serves the purpose of enabling the achievement of an appropriate air renewal.
• the chamber 23, during normal operation, is under a slight vacuum and hence is able to intake air from said interior space.
• the evaporator unit 3 is structured in such a way that at least the fan 31 is contained in a chamber which is laterally delimited by vertical or nearly vertical walls whilst its upper side and its lower side are suitable for being closed alternatively and indifferently with a wall 32 and with a grid 33 for regulating the outflow of air.
• the grid 33 can be mounted superiorly or inferiorly whilst the wall 32 is correspondingly mounted to close the lower side or the upper side of the chamber inside which the fan 31 is contained. This is made possible by the choice of a radial fan 31.
• the structure of the evaporator unit adaptation is very simple and quick and it is further facilitated by the characteristics of the rigid case or cover 4 which has approximately parallelepiped shape and is provided with a slit 41, extending in width in proximity with an edge of the front face 42 of the case itself.
• the slit 41 occupies the entire width of the rigid case of cover 4 and it is set up to be easily inserted (and extracted), with a snap-on coupling without screws or other fastening organs, a closure element 43.
• the latter comprises a half constituted by an open area, provided with the grid 33, to allow the passage of air flowing out of the evaporator unit 3, and another half constituted by a panel destined to house indication and control organs, in addition to the mouth 24.
• the rigid case 4 is suitable to be coupled indifferently on the assembly formed by the condenser unit 2 and by the evaporator unit 3 with the slit 41 positioned superiorly or with the same slit 41 positioned inferiorly.
• the closure element 43 in turn can be mounted in the slit 41 in such a way as to have its own open area always facing the grid 33.
• a third hole 50 for the exterior communication of the evaporator unit 3 is shown.
• a motorised shutter 51 and an electrical fan 52 are installed on said hole.
• a renewal of the air in the space can be achieved by activating the opening of the shutter 51, and the electric fan 52, so as to replenish in pressure equilibrium any air ejected outwards through the mouth 24.
• the apparatus may also work as a heat pump.
• the functions of the two exchange units (2) and (3) will be inverted, with the first unit (2) serving as an evaporator unit, and the second one (3) as a condenser unit.
