R600a

Features R600A, which is a hydrocarbon (HC), is used for household refrigerators and vending machines. Especially in household refrigerators, most of them use R600a. In addition, it is used as a fuel of the cassette cylinder by using the nature of burning besides the refrigerant as you know. Since r600a is a natural refrigerant that … Read more

AMOLEA 370Y2

Features HFO-1123, the main component of AmoleaX and Y, has zero ozone depletion coefficient (ODP) and a global warming coefficient (GWP) is less than or equal to 1, and has a very low impact on the global environment. Although this HFO-1123 has very high performance in refrigerant performance and environmental performance, it was known that … Read more

EPA’s Proposed Changes to Midea opts for Honeywell’s A1 aircon refrigerant R466A

USA/CHINA: Chinese manufacturer Midea is looking to use Solstice N41 (R466A), Honeywell’s new non-flammable, lower GWP refrigerant, in all its VRF and chiller systems. Honeywell’s partnership with Midea Group, follows “promising” test results with the new refrigerant announced by fellow air conditioning manufacturer Toshiba Carrier in January. “As the first non-flammable refrigerant replacement for R410A, … Read more

R744

Features Heat pump water heaters and car air conditioners, are also used as refrigerant in the binary refrigeration cycle of refrigerated showcases. When used as a hot water heater, it is characterized by being extremely high pressure and exceeding the supercritical zone and becoming a transcritical cycle. The reason why the use of CO2 , … Read more

R1234ze (Z)

Features R1234ze (Z) is a very low refrigerant for GWP. Due to the high critical temperature, it is not suitable for use in air conditioners or refrigerators, but it may be used for high temperature heat pumps. Refrigerant number R1234ze (Z) Name CIS-1, 3, 3, 3-Tetrafluoropropene Category HFO (Hydrofluoroolefin) Molecular structure ODP 0 GWP 1 … Read more
