Definitions

  • the present invention relates to an air conditioner that takes air into a cabinet thereof, then conditions the taken air, and then sends out the conditioned air into a room.
  • FIG. 28 shows the behavior of air streams in a room as observed when this air conditioner performs heating operation.
  • An indoor unit 1 of the air conditioner is installed on an upper part of a side wall W1.
  • an blowout port (unillustrated) is provided in a lower part of the indoor unit 1.
  • a start-up state that is, a state in which heating operation has just been started and thus the room temperature rises quickly
  • air is sent out via the blowout port (unillustrated) vigorously, for example at a "high" wind speed (about 5 to 6 m/sec), and substantially straight down, as indicated by arrow B.
  • the air flows inside the room R as indicated by arrows, and returns to a suction port 4 provided in an upper or front part of the indoor unit 1.
  • FIG. 29 shows the behavior of air streams inside the room as observed in a stable state, that is, a state in which the room temperature has stabilized within a predetermined range around the user-specified temperature.
  • Conditioned air is sent out via the blowout port at a "low" wind speed and substantially straight down as indicated by arrow B'.
  • the air flows inside the room R, and returns to the suction port 4.
  • the wind speed is increased again. In this way, the room temperature is kept around the user-specified temperature.
  • Patent Publication 1 discloses an air conditioner in which the orientation of a wind direction plate can be varied so that conditioned air can be sent out via an blowout port substantially straight down.
  • EP0811310 A2 discloses an air conditioner in which at least one up-down wind direction board rotates in on up-down direction around an almost horizontal rotation axis as the center within an air outlet, and a plurality of lateral wind direction boards rotating laterally are provided around rotation axes as the center which are almost orthogonal to the rotation axes of said up-down wind direction board.
  • FIGS. 30 and 31 show the temperature distribution inside the room as observed when heating operation is performed at a "high" wind speed in a start-up state ( FIG. 28 ) and at a "low” wind speed in a stable state ( FIG. 29 ), respectively.
  • the user-specified temperature that is, the desired room temperature
  • the room R is six- talami -mat large (2 400 mm high by 3 600 mm wide by 2 400 mm deep). Measurements are taken at a total of 48 spots, that is, six by eight spots at 600 mm intervals in the height and width directions, respectively, on a middle cross section of the room R indicated by dash-and-dot lines D in FIGS. 28 and 29 .
  • the warm air that the indoor unit 1 sends out straight down to frontward down has a low specific gravity and thus receives a strong buoyant force.
  • the direction of the warm air is bent sharply frontward.
  • the warm air pours directly into the living space. If the warm air continuously pours onto the head of the user, he feels discomfort.
  • the conditioned air that the indoor unit 1 sends out straight down not only has a low speed but also a low specific gravity and thus receives a strong buoyant force.
  • the conditioned air goes up as indicated by arrow B'.
  • FIG. 31 only an upper part of the room R is heated, while a part thereof close to the floor surface is not. The user feels cold in a lower part of his body, while warm air directly hits his head. The user thus feels great discomfort.
  • FIGS. 28 and 29 also show that part of the conditioned air sent out from the indoor unit 1 goes up as indicated by arrow B" and is immediately taken in by the indoor unit 1 without circulating inside the room R, causing a so-called short circuit.
  • the air around the indoor unit 1 is overheated, and the temperature close to the suction port 4 becomes 3 °C or more higher than the user-specified temperature of 28 °C, producing a so-called pool E of warm air. This diminishes air conditioning efficiency.
  • An object of the present invention is to provide an air conditioner and an air conditioning method that offer enhanced comfort and enhanced air conditioning efficiency.
  • an air conditioner according to claim 1.
  • Preferable features are set out in the depending claims.
  • the air taken in via the suction port is heated, and is then sent out via the blowout port, for example, in a frontward-upward direction.
  • the conditioned air comes to be sent out via the blowout port, for example, in a rearward-downward direction.
  • Examples of the operating status of the air conditioner based on which the wind direction can be varied include: the temperature of the air sent out from the air conditioner; the temperature of the indoor heat exchanger provided in the indoor unit; the wind volume of the air sent out from the air conditioner; the operating frequency of the compressor that operates a refrigeration cycle; the current consumption or power consumption by the air conditioner; and the wind volume of the air taken into the outdoor unit.
  • examples of the air conditioning status inside the room based on which the wind direction can be varied include: the temperature inside the room; the humidity inside the room; the purity of the air inside the room as evaluated based on the presence of odor-producing substances or the amount of dust present; and the ion concentration inside the room.
  • the conditioned air when the blowout temperature is low, the conditioned air is sent out in a substantially horizontal direction or a frontward-upward direction.
  • the blowout temperature reaches a predetermined temperature that does not make the user feels cold even if exposed directly thereto, and thus a start-up state is reached in which the room temperature rises quickly, the conditioned air comes to be sent out in a substantially straight downward direction or a rearward-downward direction.
  • the room temperature stabilizes within a predetermined range around the user-specified temperature, and thus a stable state is reached, the conditioned air is sent out in a slightly frontward downward direction.
  • the wind direction of the conditioned air can be varied. This prevents the user from being continuously hit by warm air, and thus helps alleviate discomfort and instead enhance comfort to the user.
  • high-temperature air is sent out via the blowout port in a rearward-downward direction so as to quickly perform air conditioning; in a stable state in which the room temperature has stabilized, the wind direction, wind speed, and wind volume are so varied as to achieve enhanced comfort.
  • the wind direction can be varied based on the operating status of the air conditioner, such as the temperature of the air sent out via the blowout port, the temperature of the indoor heat exchanger, the operating frequency of the compressor, the current consumption or power consumption by the air conditioner, or the wind volume of the air sucked in via the suction port of the outdoor unit.
  • the operating status of the air conditioner such as the temperature of the air sent out via the blowout port, the temperature of the indoor heat exchanger, the operating frequency of the compressor, the current consumption or power consumption by the air conditioner, or the wind volume of the air sucked in via the suction port of the outdoor unit.
  • the conditioned air is sent out at a high blowout temperature, it is sent out more rearward to reduce the high-temperature air that hits the user. This helps further alleviate discomfort to the user.
  • the wind direction can be varied based on the wind volume sent out via the blowout port. For example, when the wind volume is high, the conditioned air is sent out in a rearward-downward direction to achieve efficient heating while alleviating discomfort to the user. By contrast, when the wind volume is low, the conditioned air is sent out in a more frontward direction to make it reach so far as to achieve heating up to all corners of the room.
  • the wind direction, wind speed, and wind volume can be varied based on the air conditioning status inside the room, such as the temperature inside the room, the humidity inside the room, the ion concentration inside the room, or the purity of the air inside the room.
  • the air conditioning status inside the room such as the temperature inside the room, the humidity inside the room, the ion concentration inside the room, or the purity of the air inside the room.
  • the difference between the actual degree of air conditioning inside the room and the user-specified degree of air conditioning is large, the conditioned air is sent out in a more rearward direction to widely agitate the air all over the room in order to quickly achieve a higher degree of air conditioning up to all corners of the room.
  • the conditioned air is sent out in a straight downward direction to reduce the part thereof unnecessarily sent out rearward in order to achieve efficient air conditioning.
  • inhibiting means is provided that inhibits the conditioned air from being sent out in a rearward-downward direction or a substantially straight downward direction.
  • the wind direction of the conditioned air in a start-up state in which the room temperature quickly rises, is set in a substantially straight downward direction or a rearward-downward direction; in a stable state, the wind direction of the conditioned air is set in a direction more frontward than in the start-up state.
  • the conditioned air in a stable state, in which the wind volume is low, the conditioned air can be sent out to reach far.
  • the conditioned air is sent out in a substantially horizontal direction or a frontward-upward direction.

Abstract

Une unité intérieure (1) de dispositif de traitement d'air est montée sur la partie supérieure d'une surface de paroi (W1), une ouverture d'aspiration (4) et une ouverture de sortie d'air (5) étant situées respectivement sur la face avant et la partie inférieure de ladite unité (1). Des parties de modification du sens du vent (113a, 113b, 113c) sont capables de modifier le sens de sortie du vent d'un sens horizontal vers l'avant à un sens vers le bas et vers l'arrière. Au début du réchauffement, l'air conditionné est envoyé obliquement vers le bas vers la surface de paroi (W1). L'air conditionné tombe le long de la surface de paroi (W1) sous l'effet de Coanda, passe au-dessus d'une surface de sol (F) et circule dans la pièce. En fonction de la stabilité du réchauffement, les parties (113b, 113c) limitent le trajet d'écoulement d'air afin d'envoyer un volume réduit d'air conditionné.
