Although mechanics tell owners that the high pressure is due to a problem with the accumulator or evaporator that is not likely the case. Difficult to ignite HFO-1234yf due to high Minimum Ignition Never use the high-side port to add refrigerant, doing so is very dangerous and could cause harm. In other words, refrigerant gas returns to the compressor through the suction line from the cooling coil (which is cooling building air). R-1234yf is a denser refrigerant, and the compressor with the 2.0L turbo is very close to the front engine mount, leading to the problem. R-134a and R-1234yf have similar pressure/temperature curves. Low pressure side high90-100 needle far left high side 65 needle far right. P. R1234yf manual high side coupler - complete Q. Carbon dioxide as a refrigerant operates in a very high-pressure cycle, with low-side pressures perhaps reaching 500 psi and high-side pressures going over 2000 psi. ALSO starting in 2013, many vehicles began using 1234YF refrigerant. Since then, GM has been gradually switching over its entire line of vehicles to R1234yf, and Ford has also begun using it, too. comparing R1234yf and R134a confirmed the trends observed during the numerical study. Typically, a high-side pressure receiver is installed between the condenser and the subcooler in order to separate liquid from vapor before liquid runs through the subcooler. Andy Jones on October 21, 2019: Hi. Although the latter is a denser refrigerant, you might wonder about using one machine for both refrigerants. The cooling capacity for a pressure ratio of 2. Press OK to recover, select VACUUM to bypass RECOVER, or press ESC to exit. Low side pressure is high and high side pressure is low. Talley, Eugene, R1234yf Refrigerant (2010). Page 45 If system pressure is below 0 bar gauge, until pressure increases, the display reads SYSTEM EMPTY CHECK CONNECTIONS RECOVER ANYWAY? Usually indicates an over charged system. Safe service When accompanied by a fluctuating digital reading, usually indicates faulty reed valves in compressor. 1/2 ACME-M x 1/2 ACME-F LH thread tank adapter for R1234yf R. 12mm-M x 14mm-F R1234yf adapter (hose to R1234yf You will notice an R12 style fitting right away as the hose screws on to attach and has the look of a tire valve, while an R134A fitting is a larger quick-connect. Purdue University Purdue e-Pubs International Refrigeration and Air Conditioning Conference School of Mechanical Engineering 2010 Refrigerant R1234yf Performance Comparison In 2014, Fiat Chrysler began filling the air conditioning systems on almost all of its models with R1234yf refrigerant. Remarks With the same gas concentration (0. This spring warm. That same year, General Motors (GM) began using it in the Cadillac XTS. Low side pressure is high and high side pressure is low. It would have to be based on R-1234yf requirements for the flammability factor, but it could be a reasonable stretch. High-side air conditioner compressor pressure: output (high side pressure during operation) is the pressure of the compressed refrigerant gas as it leaves the compressor motor. Verify high-side (red) and low-side (blue) hoses are connected and coupler valves open. Mechanics often misdiagnose high-pressure gauge readings in a car's air-conditioning system. They did a diagnostics and say the high side pressure is too high and suggest taking it One can think of the subcooler not only as I took my 2006 Mazda 5 in for a diagnostics as it hasn't been blowing an cold air for past few months. 1234YF Recover, Recycle, Recharge Machine The AC1234-6 was the first commercially available machine to fully meet the SAEs requirement for recovering, recycling and recharging vehicle A/C systems that use the new R1234YF refrigerant.
