PURPOSE:To achieve the air conditioning of a large room at optimum state, a room having a large depth or a room which needs to be illuminated always by providing illuminating appliances etc. which are connected to a wall panel having a heat pump window so that by taking the heat away from the illuminating appliances etc. by the air drawn from the room, the heat of the illumination etc. may be removed when cooling, and such heat may be utilized for the room heating when heating is desired. CONSTITUTION:When a wall panel 10 having a window is to be operated as a cooling unit, a selecting switch is operated to set a heat exchanging means inside a waist-high wall so that an outside unit 26 may work as a condenser, and a room unit as a vaporizer. Further, a switch plate 64 in a ceiling ventilating an illuminating panel 12 is disposed in a position that is parallel to the direction from the window side to the farther side. When heating, the selecting switch is operated to set the heat exchanging means in the waist-high wall so that on the contrary to the cooling mode the heat exchanging means 34 of the room unit 28 may work as a condenser, and the heat exchanging means 32 of the outside unit 26 as a vaporizer. At the same time, the switch panel 64 in the ceiling ventilating and illuminating panel 12 is moved from the solid line position to the dotted line position. |
