Because R-410A can absorb and release more heat than R-22, your air conditioning compressor can run cooler, reducing the risk of compressor burnout due to overheating. R-410A also functions at a higher pressure than R-22, so new compressors are built to withstand greater stresses, reducing the chance for cracking.Geothermal/Water Source Heat Pump • R-410A Refrigerant • 0.75-1.5 Ton Single Speed. ... Where ‘gpm’ is waterflow in gpm and ‘Press Drop’ is the pressure drop through the unit heat exchanger at rated water flow in feet of head.
