- SUMMARY Window mounted air conditioners are used extensively for cooling a single room of a dwelling, and unless the room area is too great, fairly satisfactory results can be achieved. However, if the room area is too great, unsatisfactory results are realized because the cool air can be blown but a relatively short distance from the air conditioner and the warmer air outside such small area is not drawn into the air conditioner for cooling purposes. Thus, although some cooling of the room certainly takes place, it is very inefiicient and inadequate because of the lack of adequate air circulation between all parts of the room and air-conditioner. So far as cooling an adjoining room, this is not possible on any appreciable basis even though the two rooms are in communication with each other, and this again is due to the fact that there is inadequate circulation of the air between the areas to be cooled and the air-conditioner unit.
- This invention makes possible the efiicient and satisfactory cooling of the air in adjoining rooms by a single room air-conditioner unit. This does not involve any great alteration of the structure of the rooms. All that is necessary is the provision of an opening in an outside wall in one room adjacent the partition wall and in that opening the air conditioner is mounted in such manner that the condenser is on the outside and the evaporator is positioned adjacent the partition wall through which an opening leads to the adjoining room.

Int. Cl. F25d 23/12 US. Cl. 62-263 1 Claim ABSTRACT OF THE DISCLOSURE An air-conditioner device for two adjacent rooms Separated by a partition wall which extends to an outslde wall. In such outside wall and disposed in the region of the partition wall is an opening, in which is mounted an air-conditioner unit, which can be installed and removed from the inside of the room. An opening in the partition wall communicates with the evaporator of the air conditioner and a motor-driven fan adjacent the evaporator draws air from one room, passes same about the evaporator and into the other room. A suitable opening in the partition wall remote from such outside wall enables circulation of air from one room to the other. An imperforate partition separates the air conditioner into two compartments, in one of which is the evaporator and its fan, and in the other is arranged the motor-compressor and condenser, as well as a fan for cooling same.
SUMMARY Window mounted air conditioners are used extensively for cooling a single room of a dwelling, and unless the room area is too great, fairly satisfactory results can be achieved. However, if the room area is too great, unsatisfactory results are realized because the cool air can be blown but a relatively short distance from the air conditioner and the warmer air outside such small area is not drawn into the air conditioner for cooling purposes. Thus, although some cooling of the room certainly takes place, it is very inefiicient and inadequate because of the lack of adequate air circulation between all parts of the room and air-conditioner. So far as cooling an adjoining room, this is not possible on any appreciable basis even though the two rooms are in communication with each other, and this again is due to the fact that there is inadequate circulation of the air between the areas to be cooled and the air-conditioner unit.
This invention makes possible the efiicient and satisfactory cooling of the air in adjoining rooms by a single room air-conditioner unit. This does not involve any great alteration of the structure of the rooms. All that is necessary is the provision of an opening in an outside wall in one room adjacent the partition wall and in that opening the air conditioner is mounted in such manner that the condenser is on the outside and the evaporator is positioned adjacent the partition wall through which an opening leads to the adjoining room. If the partition wall, at a place remote from such outside wall, has an opening so that the air from the room in which the air conditioner is located is in communication with the adjoining room, a complete circulation of air is achieved so that by the use of a single air-conditioner unit, such adjoining rooms can be efi'ectively air cooled. This is not only advantageous from the standpoint of achieving satisfactory air cooling for two adjoining rooms, but also reduces the expense because a single air conditioner can actually work more efficiently than a window type airconditioner arranged in each of these rooms.
BRIEF DESCRIPTION OF THE DRAWINGS FIGURE 1 is a diagrammatical plan view showing 3,501,926 Patented Mar. 24, 1970 rooms with a single air-conditioner unit arranged so that both rooms can be efficiently air cooled; and
FIGURE 2 is an enlarged fragmentary perspective view showing the mounting of the air-conditioner unit and the opening in the partition wall through which air can pass from the adjoining room.
DESCRIPTION OF THE PREFERRED EMBODIMENT The illustrated embodiment of the invention comprises a pair of adjoining rooms A and B, which are separated by a partition wall 10 in which is remotely disposed a door opening and a door 11, and on the far side of the door toward the adjacent wall is a grille covered opening 12. The outside walls are indicated by the reference numerals 13 and the inside walls by the reference numerals 13a. Windows 14 are indicated on the outside walls, and in one of the inside walls is indicated a door opening and an outside door 15. It should be noted that one of the outside walls 13 is common to both rooms. As shown, the room B, which is somewhat larger than the room A, may constitute the living room of an apartment and the room A, the bedroom. In the room B near the partition wall 10 is an opening 16 in the outsidewall 13 into which fits an electric driven air-conditioner unit 17, approximately half of which extends outside of the respective wall 13 and half inside of the room B. The air-conditioner unit 17 is mounted in a suitable sheet metal shell or housing 17a, which is suitably anchored in the opening and braced on the outside by one or more brackets 17b, the shell being such that the air-conditioner unit 17 can be readily slid into or out so that it can be readily arranged for use, but may be slid into the room B for servicing or repairs. Thus, the air-condi tioner can be readily mounted in position of use from the inside of the room B and similarly can be withdrawn therefrom as desired.
The air-conditioner unit is generally of a well known type and includes a casing having an electric motor-compressor unit 18 arranged generally centrally of the unit, a condenser .19 disposed outside of the respective wall 13, and evaporator 20 on the inside of the room B generally aligned with the condenser 19. About in line with.
the respective outside wall 13 is an imperforate partition 21 suitably curved partially to embrace the motor compressor unit 18 and which extends transversely of the air-conditioner unit to separate the same into an inside compartment I and an outside compartment 0, the motor compressor unit 18 and condenser 19 being in the outer compartment 0 and the evaporator 20 in the inside compartment I. As will be readily understood by those skilled in this art, the motor compressor unit is connected by suitable tubing to the condenser 19 and evaporator 20. Provided in the partition wall 10 in the region of the evaporator 20 is an opening 22 havinga short pipe connection 22a to the evaporator and this opening 15 suitably covered by a grille or louvers 23.
For cooling the condenser 19 is a fan 24, which is preferably of the squirrel cage or sirocco type, and directly back of the evaporator 20 is a similar fan 25 for the purpose of drawing in air from the room A through the opening 22 and pipe 22a, over the evaporator 20 and forcing the cooled air out into the room B through an opening 26 in the side of the unit. For driving the fans 24 and 25 is an electric motor 27, which extends partially through the partition wall 21 with suitable surrounding seal. As shown, the armature shaft of the motor 27 projects in opposite directions so that one shaft extension drives the fan 24 and the other the fan 25. Manifestly, the shrouds for the respective fans 24 and 25 are arranged so as to effect the desired direction of air flow.
In operation, it will be understood that air from the room A is forced by the fan 25 into the air-conditioner chamber I over the evaporator 20 and thus cooled, and the cooled air is forced by the same fan into the room B through the opening 26. In the event that the door 11 is closed, the air from the room B passes through the grille or opening 12 into the room A, but should the door 11 be open, then the air may pass through both the door opening and grille so as to effect complete circulation of air. The direct draft from the blower or fan 25 is in the larger room B, thereby to efiect adequate cooling of this room since the air is caused fully to circulate therethrough. The only noise created by air conditioners of this type is by the fan or blower, and since the fan 25 is disposed in the room B, or the living area, the room A, above designated as the bedroom, will be quieter. In effect, both rooms are maintained at nearly the same temperature since a constant circulation of air is maintained from one room to the other. Thus, by the use of a single air conditioning unit both rooms are satisfactorily cooled.
A particular advantage of this system is the ease by which the air conditioner unit can be mounted in position of use or removed for servicing and the like. It will be readily apparent that this can be achieved from the inside of the room B so that regardless of the height above the ground no difficulty is encountered in the handling of the unit.
Numerous changes in details in construction, arrangement and choice of materials may be effected without departing from the spirit of the invention, especially as defined in the appended claim.
