Further, stress exerted on the fans can be minimized by alternately operating the first and second fans with predetermined time intervals between the driving of them.
  • FIG. 15 is a schematic view showing an indoor temperature/humidity control system according to an embodiment of the present invention. As shown in Figs.
  • the system further comprises a control unit 900 for transmitting commands for controlling rotational speeds of fans to the controllers 20 of a plurality of air conditioning parts 300a, 300b and 300c in a space with the air conditioning parts installed therein.
  • the control unit 900 outputs signals for controlling the first and second fans 320 and 330 of each of the air conditioning parts 300a, 300b and 300c such that the amount of air to be introduced is substantially identical with the amount of air to be exhausted to achieve rapid ventilation of a room.
  • the remaining air conditioning part is operated to exhaust 100 m 3 /h of air by operating the first and second fans thereof at a rotational speed that is two times as large as that of the fans of the two air conditioning parts.
  • control may be achieved according to flow rates of the fans of the installed air conditioning parts.
  • the indoor temperature/humidity control system of this embodiment may be operated in cooperation with a range hood 700 installed in a kitchen.
  • the control unit 900 monitors the operation of the range hood 700 and outputs a signal for an air suction operation to the controller 20 of the air conditioning part 300 if the range hood 700 is operated, so that odors of cooked foodstuffs are exhausted by the range hood 700 and fresh air is introduced by the air conditioning part 300, thereby rapidly removing the odors of the cooked foodstuffs from a room.
  • the air conditioner of the present invention is compactly installed within a room and the exterior thereof is covered with a cover, there are advantages in that it is not necessary to install conventional complicated air flow ducts, the air conditioner can be conveniently installed, and the beauty of an installation space is not spoiled. Further, since filters made of charcoal are used to achieve heat exchange of air to be introduced and exhausted, there are advantages in that energy can be saved and humidity can be easily controlled. Moreover, since the duration of air suction and exhaust operations is controlled in consideration of a difference between measured indoor and outdoor temperatures, there is advantages in that waste of energy can be prevented in a season in which the difference between the indoor and outdoor temperatures is large, and maximum ventilation effects can be obtained.
  • the air conditioner is caused not to operate, thereby avoiding the occurrence of a problem in which the air conditioner may be damaged due to undue operations.
  • suction pressure and exhaust pressure are caused to be substantially identical with each other.
  • ventilation efficiency of indoor air is maximized.
  • the air conditioner is operated in cooperation with a range hood installed in a kitchen, there is an advantage in that when the range hood performs an exhaust operation, the air conditioner performs an air suction operation to rapidly remove odors of cooked foodstuffs.

Abstract

Le climatiseur avec échangeur de chaleur de l'invention aspire et évacue l'air intérieur d'une part, l'air extérieur d'autre part, tout en rendant possible un échange de chaleur et d'humidité entre l'air intérieur aspiré et évacué d'une part, l'air extérieur aspiré et évacué d'autre part. Ce climatiseur comprend: un carter sous forme d'enveloppe creuse comportant des trous traversant d'aspiration et d'évacuation sur ses surfaces tant longitudinales que transversales et qui est agencé de sorte que l'un de ses côtés communique avec l'extérieur; des moyens d'échange de chaleur/humidité disposés dans le carter dont la fonction est d'absorber et de compléter l'échange de chaleur et d'humidité avec l'air passant à l'intérieur du carter; un premier ventilateur disposé dans le carter, qui aspire l'air de la pièce et le rejette à l'extérieur; un second ventilateur disposé dans le carter, qui aspire l'air extérieur et le rejette dans la pièce; une première sonde thermométrique montée sur un côté du carter, contre l'extérieur; une seconde sonde thermométrique montée dans la pièce; une unité de commande qui reçoit des valeurs émises par les première et seconde sondes thermométriques, calcule un différentiel de température et commande en alternance le premier et le second ventilateur pendant un laps de temps prédéterminé si l'écart de température se situe dans une plage spécifiée de différentiel de température.
