Patent ID: 8850847

Claim:
An air conditioner comprising: a compressor to compress a refrigerant; a condenser to condense the refrigerant from the compressor; an expander to expand the refrigerant from the condenser; an evaporator to evaporate the refrigerant from the expander; a refrigerant pipe to bypass the refrigerant from the condenser to an inlet side of the compressor, the refrigerant pipe being formed of one of copper, aluminum and steel; a valve to control the refrigerant in the refrigerant pipe, an insulating sheet on an outer surface of the refrigerant pipe; a pair of electrodes on an upper surface of the insulating sheet and connected to a power supply line, the pair of electrodes including a first electrode and a second electrode spaced from the first electrode; connection members to surround the refrigerant pipe to connect the pair of electrodes to the power supply line, the connection members including a first connection member coupled to the second electrode and a second connection member coupled to the first electrode; and a carbon nanotube heating element on the pair of electrodes to generate heat using power from the pair of electrodes, and wherein the pair of electrodes are between the insulating sheet and the carbon nanotube heating element, a length of the first electrode is shorter than a length of the second electrode, and the second connection member includes a bent portion to prevent the second connection member from contacting the second electrode.
