UN Number
Alternative R22, mainly used in home air conditioning, small commercial air conditioners (SME unit air conditioners, residential central air-conditioning, multi-line), mobile air conditioning (auto air conditioning, etc.), dehumidifiers, refrigerated dryers, marine refrigeration equipment, industrial refrigeration and other refrigeration equipment.
Storage and transportation
R407C refrigerant cylinders for pressurized containers should be stored away from fire, heat, avoid direct sunlight, usually put storage in a cool, dry and ventilated warehouse; handling with care, light disposal to prevent damage to the cylinder and valves and other accessories .
R407C refrigerant Freon R22 is an alternative to the newly installed refrigeration equipment easiest choice (usually air-conditioning systems); R407C and R22 but due to physical and chemical properties, the theoretical cycle performance and compressor oil, etc. are not the same, so for the initial installation of R22 refrigerant refrigeration equipment sales service, if you need to add or replace refrigerant, still only add R22, R407C usually can not directly replace R22 (ie usually not conduct shake-style replacement.
