Patent ID: 6836947

Claim:
A method for disassembling an air conditioner including a heat exchanger, comprising the process of: separating the heat exchanger from the air conditioner by cutting both ends of the heat exchanger; wherein the process of separating the heat exchanger uses a cutting device comprising: a rotor with a principal plane, a spindle provided in a normal direction to the principal plane, and at least one impacting body mounted on the spindle rotatably, wherein 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, and the separating process cuts/processes the heat exchanger by rotating the rotor at a high speed to allow the impacting body to impact on at least the heat exchanger at least at a critical impact velocity.
