Another round of air conditioning refrigerant price rose sharply

in December, the European air conditioning refrigeration industry will face high GWP refrigerants R404A, R507A price further dramatic growth, or as high as 60%. Even low GWP R404A alternatives, such as R448A, R449A, are faced with from next month up to 20% of the rise in prices. Refrigerant R410A air conditioning contractors and end users are facing up to 30% of the price rise.

R - 404 - a refrigerant, because R404A to HFC type non azeotropic refrigerants (environmental protection Entirely without damage to the ozone layer of the CFC, as) , now the international recognized the vast majority of countries and introduce the mainstream of the low temperature environmental protection refrigerants, widely used in new refrigeration equipment to add in the process of die erste installation and maintenance. Fit the environmental arrangement EPA, SNAP and UL specification, fit into the American society of heating, refrigeration and air conditioning engineers ( ASHRAE这样) A1 security level category ( This is the highest level, harmless to human body) 。 R - 404 a as today's widely used in low temperature refrigerant, often used in cold storage, food refrigeration equipment, Marine refrigeration equipment, industrial cryogenic refrigeration, commercial refrigeration, transport refrigeration equipment at low temperature ( Refrigerated trucks, etc. ) , refrigeration condensing units, such as supermarket display showcase refrigeration equipment. R404A refrigerant is new clothes instead of freon refrigeration devices most throughout the industry norms of refrigerants of R22, r114? ( Generally for low temperature freezing system) ，. R - The physicochemical properties name of refrigerant R - 404 - a 404 a molecular weight of 97. 6 the boiling point ( 1 atm) ℃ - 46. Eight critical temperature 72 ℃. 1 critical pressure, kPa3732 full steam pressure ( 25℃） , kPa1255 transpiration latent heat of vaporization/( Below boiling point, 1 ATM) , kJ/kg207 damaged ozone ozeme depletion potential ( ODP) 0 ozeme depletion potential global warming, GWP, 100年) 3800 ashrae security level A1 ( Non-toxic nonflammable) - - - - - - - - - - - - Thus R404A is attributed to ban of freon. And he is now the international recognition of the vast majority of countries and introduce the mainstream environmental protection refrigerants in low temperature.

R507 is made from a mix of R125 / refrigerant R143 refrigerants, is a kind of the environmental protection refrigerant does not destroy the ozone layer.

the above are environmental protection refrigerants, and the state advocates the usage amount of refrigerant, chemical sales of new environmental protection refrigerants, authentic, high content, good quality, welcome customers to come to consult!
