Which risk increases when a chiller using R-134a reaches low suction pressure?

💡 Explanation

If suction pressure is too low, the superheated refrigerant entering the compressor will be excessively hot because R-134a temperature depends strongly on phase. This will cause the compressor motor winding overheating, therefore increased thermal stress and insulation breakdown, rather than less likely flow reductions and tube faults which depend on separate issues.
