ABSTRACT:
An air conditioner includes an air inlet and an air outlet, an electric dust collector for removing dust from the air, a refrigerant-conducting heat exchanger for changing a temperature of the air, a fan for circulating air through the air conditioner, and an electrical heater which is energized when the fan and the electrical dust collector are energized, for heating the cleaned air. The electric dust collector communicates with only a lower portion of the air inlet. A closure mechanism for opening and closing the air inlet is operable to open only the lower portion of the inlet to insure that all of the air entering the air conditioner passes through the electrical dust collector during an air cleaning operation.
