[Experience] What happens if the compressor suction pressure is too high and the discharge pressure is too high

[Experience] What happens if the compressor suction pressure is too high and the discharge pressure is too high Compressor suction pressure is too high, discharge pressure is too high 1. Too much refrigerant. Too much refrigerant will cause the suction pressure and discharge pressure to be too high at the same time. This is because when too much refrigerant fills the reservoir, it will occupy a part of the condenser volume, reducing the heat dissipation area and causing the condenser Poor condensation. Discharge excess refrigerant from the low-pressure side.
