Co2 r744 transcritical

Even though CO2 is environmentally benign, the performance of CO2 HP has been of concern since its inception. To improve the performance of CO2 HP, research has been playing a pivotal role in developing functional designs of heat exchangers, expansion devices, and compressors to suit the CO2 transcritical cycle. 2017-08-31 · The operating pressures of CO2 or R744 on a subcritical system are similar to R410A air conditioning system. Please refer to a refrigerant pressure-temperature chart for exact pressures. See AE-1372 for additional information.
