activates the heat exchange filter driving means 170 heater driving means 190 and fan motor driving control means 150 in order to heat exchange the sucked in room air to warm air and at the same time signals are sent out to the respective output ports in order to display to the outside whether or not the means 170 190 and 150 are activated as seen from the aforesaid the system controller 130 discriminates whether or not the water temperature within the water tank detected by the water temperature detecting means 157 is the adequate level and if the water temperature within the water tank is increased by the activation of the heater driving means 190 here if the water temperature detected therefrom is above the adequate level the system controller 130 reverses the signal outputted from a port p21 from 34 high 34 to 34 low 34 to thereby supply the same to an inverter in14 so that the operation of the heater driving means 190 is halted if the detected water temperature is below the adequate level the system controller 130 keeps activating the heater driving means 190 to thereby increase the water temperature within the water tank so that warm airs are always discharged within a predetermined range during a selection of warm airs as seen in the foregoing in the cooling heating air conditioner employing a circuit controlling the peripheral equipment if a fan 280 illustrated in fig3 and 4 is rotated the room air is sucked in through a plurality of holes 232 of the suction grille unit 230 by a rotating force of the fan and the dust and the like floating in the air are inducted into the interior by being filtered through an air.
