Abstract

An air conditioner which can be controlled remotely having a compressor capable of changing the number of rotations in response to a variation of frequency. The air condition includes a first sensor circuit section arranged in outdoor machinery, a second sensor circuit section arranged in indoor machinery, an operative state sensing section for receiving the output signals of the first and second sensor circuit sections and sensing the operating state of the air conditioner. The air conditioner further includes an LED display section for receiving the output signal of the operative state sensing section and displaying the operating state under control of the first microcomputer, and a first signal transmitting circuit section for transmitting a signal to a remote controller in accordance with the sensed operating state signal under control of the first microcomputer. The remote controller includes an LCD display section for receiving the transmitted signal from the first signal transmitting circuit section and displaying the circuit condition and the operating state under control of a second microcomputer.
