[Case Study] Reuse through Refrigerant Piping Cleaning during Air Conditioner Replacement
When updating the air conditioning, the existing refrigerant piping can be reused through cleaning.
If there is no damage to the existing refrigerant piping during air conditioner replacement, it can be reused through cleaning. However, when replacing an air conditioner that involves changing the type of refrigerant, it is necessary to remove the refrigerant oil from the piping. If old refrigerant oil remains in the piping, it can cause issues such as compressor damage. Our company actively promotes the reuse and effective utilization of existing piping by using a specially developed cleaning agent for refrigerant piping, tailored cleaning methods, and measuring the residual oil amount in the piping after cleaning. [Case Study] ■ Issue - Removal of refrigerant oil from the piping is necessary during air conditioner replacement. ■ Solution - Use of a specially developed cleaning agent for refrigerant piping and tailored cleaning methods, along with measuring the residual oil amount in the piping after cleaning. *For more details, please refer to the PDF document or feel free to contact us.

basic information
【Unique Cleaning Agent】 ★Verification of Cleaning Chemicals We developed a dedicated cleaning agent for refrigerant piping, "NM2000," in collaboration with a refrigerant oil manufacturer. As a hydrocarbon-based cleaning agent, it does not fall under substances that deplete the ozone layer as specified by the Montreal Protocol. We have conducted various tests to verify its cleaning effectiveness and to confirm its safety in case any chemicals remain. ★Types of Verification - Compatibility verification with refrigerant oil - Stability verification (shield tube test) - Refrigerant oil removal performance verification 【Unique Cleaning Method】 To accommodate long piping and multi-systems for buildings with multiple branch pipes, we conducted various demonstration tests to verify the optimal cleaning method, cleaning time, and cleaning precision. Our company is equipped with self-developed cleaning units and technicians, allowing us to handle large machines and industrial equipment that cannot be addressed by commercially available cleaning machines, as well as large-scale cleaning involving 20 units in a single system. 【Determination of Cleaning Effectiveness】 For our refrigerant piping cleaning, we measure the amount of refrigerant oil in the cleaning solution and submit the results as a report. By measuring the electromagnetic spectrum (wavelength and polarization) specific to refrigerant oil, we can quantitatively analyze the remaining oil based on its intensity, enabling accurate residual oil analysis regardless of dirt or discoloration.
