Definitions

  • the 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.
  • Air 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.
  • 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.
  • the air inside the cooled space absorbs heat from the walls, floor, people, and other objects inside the space being cooled.
  • FIG. 1 illustrates an air conditioning system for conditioning the air over and around a sleeping surface, such as a sleeping bed.
  • FIG. 2 illustrates a process for retrofitting a bedroom in accordance with
  • FIG. 3 illustrates an air conditioning system configured in accordance with embodiments of the present disclosure.
  • 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).
  • 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.
  • 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.
  • 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.
  • 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.

  • the canopy 102 may be a thermal insulating material fabricated from a lightweight flexible material.
  • 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.

  • 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.
  • 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 be installed, which might require access to crawl space behind the ceiling and/or walls of the room.

  • 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 be set to maintain the remainder of the room 120 at a higher temperature.

Abstract

L'invention concerne un système de climatisation ("A/C") pour le conditionnement de l'air principalement à l'intérieur d'un espace cloisonné dans lequel une ou plusieurs personne(s) habitent à l'intérieur d'une pièce ou d'une structure, le système de climatisation ne conditionnant pas l'air à l'extérieur de l'espace cloisonné dans la pièce ou la structure. Un tel espace cloisonné à l'intérieur d'une pièce ou d'une structure peut être une partie de la pièce ou structure dans laquelle un lit de couchage est positionné, et une partie de la pièce d'habitation se trouvant au-dessus du lit de couchage. Le système de climatisation peut remplacer un ventilateur de plafond existant, et être installé à la place de celui-ci. Un baldaquin est drapé sur l'espace cloisonné pour entourer la zone climatisée.
