ABSTRACT:
Using a cutting device (10) including a rotor (11) with a principal plane, a spindle (13) provided in a normal direction to the principal plane and at least one impacting body (100) mounted on the spindle rotatably, in which the impacting body is mounted so that a predetermined fitting gap is provided between the impacting body and the spindle and a part of a periphery of the impacting body can be positioned beyond a periphery of the rotor, the rotor is rotated at a high speed so as to allow the impacting body to impact on at least a heat exchanger of an air conditioner at least at a critical impact velocity. The heat exchanger is cut while a top layer of an impact portion being smashed. It is possible to disassemble an air conditioner efficiently using a cutting device having a simple configuration and a long lifetime.
