Title:
REFRIGERATOR DISMANTLING METHOD, COMPRESSION EQUIPMENT, AND REFRIGERATOR DISMANTLING DEVICE
Document Type and Number:
WIPO Patent Application WO2002006668
Kind Code:
A3
Abstract:
A method of dismantling a refrigerator, comprising the steps of collecting refrigerant gas from a disposed refrigerator, removing a compressor, dismantling an insulated cabinet including insulators by cutting into a plurality of pieces, and collecting the gas contained in the insulators by compressing the pieces with compression rollers opposed to each other, whereby the gas contained in the insulators are not almost diffused during the cutting of the insulated cabinet, the gas can be collected in high density because the gas is collected by leaking at the time of compression, independent air bubbles in the insulators can be collapsed easily and the gas can be surely collected completely by using the compression rollers, and thus the foaming gas in the insulators can be collected efficiently, and the refrigerator can be dismantled at a low cost without increasing the size and installation space of the equipment.
