1. An air conditioning system, comprising:
a compressor that compresses a refrigerant; an indoor heat exchanger that condenses the refrigerant discharged from the compressor in a heating operation; an outdoor heat exchanger that evaporates the refrigerant condensed in the indoor heat exchanger and that has an inlet to introduce the refrigerant and an outlet to discharge evaporated refrigerant; and a heater comprising:
a heating chamber formed with a passage in which the refrigerant flows and a heat transferring part having a one surface contacting the refrigerant flowing in the passage,electrodes disposed on another surface of the heat transferring part,a plurality of carbon nanotube heating elements disposed on the other surface of the heat transferring part spaced away from each other, connected to ends of the electrodes, respectively,an insulator that insulates the electrodes and the carbon nanotube heating elements, anda first conduit that connects the outdoor heat exchanger with the heater to selectively guide refrigerant evaporated at the outdoor heat exchanger to the heater;a second conduit that connects a pipe connecting the indoor heat exchanger and the outdoor heat exchanger with the heater to allow refrigerant condensed at the indoor heat exchanger to introduce into an inside of the heater, each end of the pipe being connected to the indoor heat exchanger and the outdoor heat exchanger respectively; andan indoor expansion valve disposed on the pipe to decompress the refrigerant in a cooling mode;an outdoor expansion valve disposed on the pipe to decompress the refrigerant in a heating mode;a valve disposed on the second conduit to selectively close the second conduit;a third conduit that connects the compressor with the heater to guide refrigerant heated in the heater to the compressor, andwherein the second conduit comprises a first end connected to the pipe and a second end connected to the heater, andthe pipe is connected to one of the inlet and the outlet of the outdoor heat exchanger and the first conduit is connected to the other one of the inlet and the outlet of the outdoor heat exchanger. |
