The characteristics of refrigerant r410a introduction and piping requirements

by HFC32 and HFC125 two refrigerant r410a refrigerant mixture, do not contain chlorine refrigerants, because HFC not chlorine, will reduce the lubrication performance of the compressor, so the friction parts of the texture, frozen oil, resin materials for the replacement, become a special refrigerant compressor. No compatibility with previous refrigeration oil, can adopt miscibility of synthetic oil, raised the pressure characteristics, system pressure rise, corresponding air test pressure changes, instruments and tools, refrigerant piping material and thickness changes.

advantages: no damage of atmospheric ozone layer long-term substitute for R22 and low temperature heat reduce, high unit refrigerant cooling loads.

faults: pressure is 1 of R22. About 6 times, it is necessary to improve the piping such as compressive strength.

r410a refrigerant of piping requirements:

construction requirements: in the process of purchasing copper tube wall thickness must be in accordance with requirements, the copper must be treated with skim, transportation and storage must be sealed on both ends of the pipe, prevent the copper collision damage. Installation, must adopt the corresponding special tools, practical and ensure clean, dry, air-tight system.

drying: confirm whether the tube in dry, wet when removing moisture. If there is a small amount of water mixed with, because the impedance of the moisture, prevent the circulation of the refrigerant capacity decreased and refrigeration oil hydrolytic decomposition and promote aging, cause compressor insulation fault

airtight: refrigerant piping due to high pressure gas filling, so the air is the basic requirement. Especially piping connections to ensure airtight, confirm there can be no refrigerant leakage. （ For example: the nitrogen pressure of refrigerant with tube until it reach the design pressure of the machine to the pressure distribution pipe refrigerant, until you reach the design pressure of the machine above)

to the refrigerant piping material requirements: dephosphorization seamless copper tube, drawing. Comes into play should have the factory certificate, test report. Inside and outside of the pipe surface should be no pinhole, crack, peeling, blister, inclusion, copper powder, carbon deposition layer, green rust, dirt and severe oxidation film, does not allow exist obvious defects such as scratches, pits, spots.

the above introduction about the r410a refrigerant to the over here, hope to bring you some help.
