Abstract: A refrigerant gas is collected and a compressor is removed from a discarded refrigerator, a heat-insulating housing including a heat insulator is cut/processed and separated into a plurality of pieces, and the pieces are compressed/processed by compression rollers opposing each other so as to collect a gas contained in the heat insulator. In accordance with this method, substantially no gas contained in the heat insulator is diffused at the time of cutting the heat-insulating housing, and the gas can be collected at a high concentration because it is collected by being allowed to leak out at the time of compressing. Furthermore, by using the compression rollers, closed-cells in the heat insulator can be crushed easily, thereby collecting the gas completely and reliably. Thus, it is possible to collect a foaming gas contained in the heat insulator efficiently and disassemble a refrigerator at low cost without increasing the size of equipment and an installation space.

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.
