TECHNICAL FIELDThe present disclosure relates in general to air conditioning systems, and more particularly, to an air conditioning system for a reduced space area of a room.
BACKGROUND INFORMATIONAir conditioning (“A/C”) systems are widely used for “conditioning” habitable spaces with inside closed structures such as buildings, offices, and dwellings among others. “Conditioned” air may include cooled air, warmed air, dehumidified air, or any other method by which the quality and/or properties of the air are selectively modified. Typically, an air conditioner unit removes heat from the air by passing it through a heat exchanger containing a cooling fluid, or a heat exchanger cooled by some other mechanism such as the Peltier (or thermoelectric) effect. Usually, but not always, the air inside the cooled space absorbs heat from the walls, floor, people, and other objects inside the space being cooled. A substantial part of the energy used in conventional air conditioning arrangements results only in cooling of the building structure and the objects inside the cooled space, and removal of heat entering through the roof or ceiling, walls, floor, and particularly through open or covered apertures, such as the windows and doors. This energy requirement can be reduced by providing additional insulation or by shading the roof, walls, windows, and doors. However, these measures are not always possible, particularly with older buildings not designed with energy efficiency in mind.
People often spend long periods of time at a single location within a room (such as sleeping on a bed), and it is only necessary to keep the upper body and face cooled for a person to feel very comfortable. During the night, especially during warmer months, a majority of the energy load in residential buildings, particularly within multi-family complexes, is from the air conditioner units located in bedrooms or a thermostat for a central A/C system set lower in bedrooms. In fact, A/C loads at night determine the peak electricity loads for such multi-family complexes, resulting in significant investment by the builders. Thus, any significant reduction in this peak load can result in savings and electrical power installation for the building.
Aspects of the present disclosure provide an A/C system for conditioning the air within a partitioned space in a room or structure. Aspects of the present disclosure provide an A/C system for conditioning the air primarily within a partitioned space in which one or more persons reside within a room or structure, where the A/C system does not condition the air outside of the partitioned space within the room or structure (except possibly as a result of relatively insignificant leakage through the materials creating the partitioned space). In accordance with embodiments of the present disclosure, such a partitioned space within a room or structure is a portion of the room or structure in which a sleeping bed is positioned, and a portion of the living space lying over the sleeping bed. By localizing the effect of an air conditioner unit to just a small section of the cooled space, typically away from doors, windows, and walls, very large energy savings are possible.
As a result, aspects of the present disclosure provide a reduced energy consumption A/C system for conditioning the air inside limited areas, which may include the implementation of lower cost air conditioning equipment.
Aspects of the present disclosure provide a reduced area A/C system that selectively conditions the air within a given structure. The reduced area A/C system includes an air conditioning unit connected to a reduced space inside a structure. The air conditioning unit supplies conditioned air to the reduced space area in order to selectively modify or adjust the quality and/or properties of the air inside the reduced space area. The reduced space area may be surrounded and covered by a layer or layers of a thermal insulation material. Such a thermal insulation material may be configured to reduce heat losses as well as leakage of conditioned air from the reduced space area.
An advantage of embodiments of the present disclosure is that only a smaller volume of the entire room needs to be air conditioned in comparison to the volume of the entire room or structure. Hence, only a reduced “livable” area is actually conditioned as opposed to conditioning regions or areas in the room or structure that are not normally occupied by a person during certain times of the day (e.g., during the night).
Aspects of the present disclosure provide an A/C system that is configured for conditioning air within a desired reduced space area surrounding a region of one or more articles of furniture to be occupied by at least one person.
In accordance with certain embodiments of the present disclosure, the A/C system includes an air conditioning unit that replaces a typical ceiling fan, which was previously mounted from the ceiling of the room (i.e., the overhead interior surface of a room) in which the desired reduced spaced area is located.
In accordance with embodiments of the present disclosure, the canopy 102 may be made from any well-known canopy material, such as those commercially available for creating a canopy over a sleeping bed. In accordance with embodiments of the present disclosure, the canopy 102 may be a thermal insulating material fabricated from a lightweight flexible material. For example, the canopy 102 may be made from a high thermal resistance woolen cloth material to maintain a lower temperature (e.g., 4-5 degrees lower), and possibly humidity, for the air over the sleeping bed canopy 102 relative to the remainder of the room 120 not enclosed by the canopy 102. However, other suitable materials having good thermal and insulating properties may be substituted for the canopy 102. For example, the canopy 102 may be made from other various materials, such as a thermoplastic material, acrylic, polyester, olefin, nylon, aramid, silk, spandex, linen, cotton, rayon, and acetate, to name a few. Moreover, a closely woven fabric of a cooler fiber may be utilized, since it can be warmer than a not so closely woven fabric of a warmer fiber.
The canopy 102 may be in the form of a sheet or a plurality of individual sheets (which may be fastened or attached to each other, or merely overlaying each other) surrounding and substantially enclosing the reduced space area, such as depicted in
A unique aspect of the A/C system 100 is that a low power (e.g., 100 watts) A/C unit can be utilized to replace a previously mounted ceiling fan within the room 120. In accordance with embodiments of the present disclosure, the A/C unit 101 may he mounted to the rod 103 previously utilized to mount the ceiling fan to the ceiling within the room 120. Such a lower wattage A/C unit reduces the total power consumption required for conditioning the reduced space area over the sleeping bed 110, because typical A/C units for conditioning entire rooms and structures utilize a 500 watt or greater A/C unit to maintain the entire environment for persons residing therein. Furthermore, the existing wiring that had been utilized to power the previously installed ceiling fan can now be utilized to power and/or control the newly mounted A/C unit 101 so that new wiring is not required to he installed, which might require access to crawl space behind the ceiling and/or walls of the room.
In accordance with certain embodiments of the present disclosure, the A/C unit 101 is configured to condition the air by passing it through a heat exchanger containing a cooling fluid, or a heat exchanger cooled by some other mechanism such as the Peltier (or thermoelectric) effect. Such an A/C unit 101 may utilize a freon condenser based A/C system. Control of the A/C unit 101 may be performed by a wired or wireless controller as is well known in the art.
Within certain embodiments of the present disclosure, the room 120 may also include another source of conditioned air, such as one or more vents (not shown) connected to a central A/C system (not shown), or an individual A/C unit, such as those typically installed within a hole or window of a wall of the room 120 (e.g., the A/C unit 140). In such a configuration, the combined efforts of the A/C unit 101 and the A/C unit 140 (or the aforementioned central A/C system) can be utilized to individually condition the air in the reduced space area enclosed by the canopy 102 and the air within the remainder of the room 120. A savings in electricity is still realized, since the A/C unit 101 can be set to condition (e.g., cool to a desired temperature) the reduced space area enclosed by the canopy 102, while the A/C unit 140 (or central A/C system) can he set to maintain the remainder of the room 120 at a higher temperature.
Note that in certain embodiments of the present disclosure, a vent (not shown) can be installed to exhaust the heated air (and evaporated water) from the A/C unit 101 to a location external from the room 120. In other embodiments, such heated air (and evaporated water) can be exhausted into the remainder of the room 120 outside of the reduced space area enclosed by the canopy 102. In this latter configuration, the heated air (and evaporated water) is added to the environment within the remainder of the room 120 outside of the reduced space area enclosed by the canopy 102, which is then conditioned by the second A/C unit 140 (or central A/C system).
For example, consider an exemplary room (e.g., the room 120) having dimensions of 10 ft. (“feet”)×12 ft.×8 ft., and the reduced space area enclosed by the canopy 102 has approximate dimensions of 8 ft.×6 ft.×4 ft. If the A/C unit 101 thermostat is set to about 69° F., and the thermostat for the A/C unit 140 (or central A/C system) is set to about 74° F., then the power consumption of the combined efforts of the two A/C systems will be about one third of the power consumption of solely the A/C unit 140 (or the portion of the central A/C system allocated to the room 120) in order to cool the entire room 120 to about 69° F. without the installed A/C system 100.
Referring to
Within alternative embodiments of the present disclosure, the existing ceiling fan is not replaced, but instead an A/C unit (e.g., the A/C unit 101) is combined with a ceiling fan (not shown in
It will be understood that particular embodiments described herein are shown by way of illustration and not as limitations of the disclosure. The principal features of this disclosure can be employed in various embodiments without departing from the scope of the disclosure.
The use of the word “a” or “an” may mean “one,” but it is also consistent with the meaning of “one or more,” “at least one,” and “one or more than one.” The use of the term “or” is used to mean “and/or” unless explicitly indicated to refer to alternatives only or the alternatives are mutually exclusive, although the disclosure supports a definition that refers to only alternatives and “and/or.” As used herein, the term “about” is used to provide flexibility to a numerical endpoint by providing that a given value may be “a little above” or “a little below” the endpoint.
As used herein, the term “substantially” refers to the complete or nearly complete extent or degree of an action, characteristic, property, state, structure, item, or result. For example, an object that is “substantially” enclosed would mean that the object is either completely enclosed or nearly completely enclosed. The exact allowable degree of deviation from absolute completeness may in some cases depend on the specific context. However, generally speaking, the nearness of completion will be so as to have the same overall result as if absolute and total completion were obtained. The use of “substantially” is equally applicable when used in a negative connotation to refer to the complete or near complete lack of an action, characteristic, property, state, structure, item, or result.
As used herein, “adjacent” refers to the proximity of two structures or elements. Particularly, elements that are identified as being “adjacent” may be either abutting or connected. Such elements may also be near or close to each other without necessarily contacting each other. The exact degree of proximity may in some cases depend on the specific context.
