Definitions

  • ABSTRACT An air conditionin device of thekind which can be F A 11 t P t ta 8 [30] orelgn pp ca [on r-lon y D8 6 mounted on wheels so as to be placed at any selected Apr. 24, 1971 Italy 23 35/71 position within a room which is operative in combina tion with air-discharging means placed in communica- [52] US.
  • This invention relates to a device for conditioning the environmental air of apartment rooms, comprising a refrigerating circuit, means for causing the circulation of the air treated by said circuit and means for transferring the device into said room(s).
  • a first kind of air conditioning device is adapted to be affixed into an empty space formed in a window or even through a wall: thus, the heat produced by the condenser and the compressor is removed, and the result is that the installation of the device is intricate and expensive.
  • a second kind of air-conditioning device can be transferred from one apartment room to another, but in each apartment room, it should be affixed in an opening as formed usually in a window, still with a view to removing the heat as produced by the refrigerating circuit.
  • the problem the device according to the invention intends to solve is the one of permitting an airconditioning device to be installed in any portion of the room which is even remote from a window or wall,.
  • the problem is solved by the device according to the invention which is extremely simple and inexpensive. It is characterized by first air-circulation means for circulating air in a substantially horizontal direction and by second air-circulation means for circulating air in a substantially vertical direction, with said first and second means being adapted to control air at different temperatures inthe room so as to-provide in said room at least two horizontal layers of air at different temperatures, and means are provided for activating the exchange of air appertaining to the layer having a temperature substantially higher than that of the other layers.
  • FIG. 1 is a cross-sectional view along a vertical plane of the device according to the invention.
  • FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1;
  • FIG. 3 is a cross-sectional view taken along a vertical plane of a room to be air-conditioned
  • FIG. 4 is a plan view of the room of FIG. 3.
  • FIG. 1 which shows the device in vertical crosssectional view
  • a cabinet 1 which has wheels 2 for its bottom portion, with the wheels being adapted to impart to the device the capability of being carried through the room.
  • a space 3 which houses a compressor 4 for a refrigerating unit.
  • connection 5 which carries the refrigerating fluid from the compressor 4 to a condenser 6.
  • the condenser 6 is placed in a vertical duct 7 having a mouth 8 directed upwards.
  • the arrows 9 indicate the air flow lines for the air flowing throughthe space 3 and the duct 7, which goes towards the top of the room in a linear motion.
  • the space 3 and the duct 7 which form the hot portion of the refrigerating circuit are heat-insulated towards the outside by an insulating layer 10 and towards the inside, that is, towards the cold portion of the refrigerating circuit, by an assembly of walls 1 1, 1 l
  • a line 22 (FIG. 3) indicates the separation surface between a top hot air zone above the M22 and an airconditioned zone situated thereunder.
  • FIG. .3 shows a window 23 in which, for example, an
  • FIG. 1 there can beseen a collection tank 26 for the water coming from air demoisturizing circuit, with the water dripping from the evaporator 13 into a collecting tray 27 through a duct 27'.
  • the tank 26 is removable.
  • FIG. 1 there can'be seen also a suction pipe 28 which returns from the evaporator 13 to the compressor 4 and springs 29for the elastic suspension of the compressor.
  • a pipe30 for feeding the refrigerating fluid to the evaporator 13.
  • the device according to the invention operates as follows:
  • the opening 24 of the window 23 is thus capable of discharging from the room air which is at a higher temperature and which is accumulated above the line 22, so that the line 22 remains at a level such as shown in the drawing, substantially adjacent to the room ceiling.
  • the exhauster 25 the withdrawal of warm air can be controlled by a thermostat 35 responsive to the attainment of a preselected temperature at a high-level point of the room. 4
  • the conditioning appliance according to the invention is particularly simple and unexpensive.
  • the warm air as produced by the condenser can be withdrawn from the room without any particular connections of the conditioning device with the external atmosphere.
  • the airconditioning device can be placed at any point of a room, and more particularly remote from windows or walls.
  • Thedevice the subject of the present invention.
  • a removable air conditioning unit for cooling rooms comprising a refrigeration circuit for processing the room air, said refrigeration circuit having an evaporator and a condenser, an air circulating device capable of producing at least two horizontal layers of air at different temperatures, and means for transferring the air conditioning unit in the room, the improvement that said air circulating device includes'first means provided with at least an inlet opening and at least an outlet opening, which are located substantially in the same horizontal plane, a fan and said evaporator being housed in the space between the inlet and outlet openings, second means provided with a duct having an inlet mouth situated at the bottom of the conditioning unit, said condenser being housed within said duct, said first and second means being capable of producing, respectively, a forced air circulation in a substantially horizontal direction and a natural air circulation in a substantially'vertical direction, and means for activating the removal of air belonging to the layer having a temperature substantially higher than that of the other layers.
