It was chosen as the preferred equation of state Compressor oils have to be the right type and viscosity intended for use in each particular system. BG Frigi-Charge® for R-134a, PN 704, contains R-134a (as the name implies) and is only intended for use in systems designed for this refrigerant. BG Frigi-Quiet® for R-134a, PN 701, is a suitable compressor oil for systems utilizing R-134a, but It was selected because its unique design would reduce the likelihood of cross-treading service hoses on R-12/R-134a refrigerant storage containers and service equipment. The high low pressure hose in SAE J2196 requires the charge coupling (used to connect service hoses to vehicle access ports) to be an integral part of the hose assembly. As a result of the theoretical analysis, COP HP values of all three fluids are almost the same. The COP HP values of R134a, R513A and R1234yf at − 10 °C evaporator temperature are 4.42, 4.32 and 4.30, respectively. R134a has COP HP values of 2.3% and 2.7% higher than R513A and R1234yf, respectively. performance under the same operating conditions. It shows the capacity and COP ratio of R-134a against the other refrigerants and the discharge temperature difference between R-134a and the other refrigerants. The refrigerants of lower boiling point such as R-32 gives higher capacity than those of higher boiling The same number and type of atoms make up R134 and R134a, but the arrangement differs. Although R134 is technically a refrigerant, it’s less efficient at moving heat. Does R134a contain CFC or HCFC? R-134A belongs to a group of chemicals called hydrofluorocarbons (HFCs) and is also known as HFC-134A. R-134a Safety Data Sheet R-134a 1.
