Product overview

R407C refrigerant, alias R-407C. As R-407C is a HFC type non azeotropic environment-friendly refrigerant (completely free of CFC and HCFC that destroy the ozone layer), it is recognized and recommended by most countries in the world as a mainstream medium and high temperature environment-friendly refrigerant, which is widely used in the initial installation and maintenance of new refrigeration equipment. It meets the standards of EPA, SNAP and UL, and meets the A1 safety class of ASHRAE (the highest level and harmless to human body).

Application

R407C, as a medium and high temperature refrigerant widely used today, is mainly used in household air conditioners, small and medium-sized commercial air conditioners (small and medium-sized unit air conditioners, household central air conditioners), mobile air conditioners (automobile air conditioners, etc.), dehumidifiers, refrigerated dryers, marine refrigeration equipment, industrial refrigeration and other refrigeration equipment. R407C refrigerant is the simplest alternative to freon R22 on newly installed refrigeration equipment (usually air conditioning system); However, since R407C is different from R22 in physical and chemical properties, theoretical cycle performance and compressor oil, R22 can only be added to the after-sales maintenance of refrigeration equipment initially installed with R22 refrigerant if it is necessary to add or replace refrigerant, Generally, R407C cannot be directly used to replace R22 (that is, blood exchange replacement is not allowed; however, for the refrigeration equipment that uses R22 for the first time, R417A can be directly used to replace R22 during maintenance or replacement).

Storage and transportation

R407C refrigerant cylinder is a pressurized container. It should be stored away from spark, heat source and direct sunlight. It is usually stored in a cool, dry and ventilated warehouse; Handle with care to prevent damage to steel cylinders, valves and other accessories.

Matching refrigerant oil

According to the recommendations of the refrigeration compressor and refrigeration (air conditioning) equipment manufacturers, or according to the specific conditions of the refrigeration compressor and refrigeration equipment, determine which refrigeration oil R407C refrigerant will eventually use in different equipment and different application sites. That is, select the equivalent refrigeration oil with the same design and requirements of the technician.
