- the disposal necessity reference color corresponds to the oil color that has deteriorated from the cleaning necessity reference color in Part 1 31.
- the residual oil in the pipe 9 has deteriorated so that it cannot be used even after washing. It is a standard color for determining whether the pipe 9 can be reused by performing the cleaning process. More specifically, the reference color for the necessity of disposal is a color close to the color of the color display section 48 of the above color sample table 40 (the color of the ATM color code 8).
- the check sheet indicating the necessity standard color for cleaning and the necessity standard for disposal it is possible to judge whether or not the pipe 9 must be discarded without using the color sample table 40. become able to.
- the user who uses this check sheet can use the pipe 9 even after cleaning if the color of the residual oil in the pipe 9 attached to the sampling section 33 is darker than the standard color Judging that it cannot be done and must be discarded, and if the color of the sampling section 3 3 is darker than the standard color for cleaning necessity and lighter than the standard color for discarding, the pipe 9 is reused by washing. You will decide that you can.
- the first part 31 and the second part 32 and the sampling part 33 are integrated, but the first part 31 and the second part 32 and the sampling part 33 are separate. It is also possible to use the body tool.
- a cotton swab, a rag, or the like corresponding to the sampling unit 33 may be used together with the color sample table 40, and the determination regarding the reuse of the pipe 9 may be performed based on the swab or the waste.
- the check sheet 30 and color sample table 40 can also be used to determine whether the existing air conditioner to be removed can be recycled and reused. If the residual oil in the removed air conditioner piping is severely oxidized, it is often impossible to recycle the existing air conditioner parts at all.However, remove the compressor when the degree of residual oil contamination is small. Five
- the use of the heat exchanger unit according to the present invention makes it possible to easily determine the availability of refrigerant-using equipment or refrigerant piping by color using a check tool. Useless cleaning work when the inside of the piping is not so dirty and cleaning is not necessary, or cleaning work even if the inside of equipment or refrigerant piping is dirty enough to use even after cleaning The problem of reusing them only by doing so is suppressed.
