High discharge temperature

[@HVACTechGuidebysreejith]

Boss I was too busy. If discharge temperature high . 1) Check discharge temperature sensor 2) short of refrigerant 3) over charge refrigerant 4) liquid injection not working 5) condenser Air recycling 6) Check condenser fan motors 7) compressor working unload condition long time with high chilled water temperature 8) economizer not working

1)Check suction temperature and suction pressure transducer 2) check discharge temperature sensor and discharge pressure transducer 3) check expansion valve 4)check chilled water flow 5) refrigerant overcharged 6)too much oil in the evaporator
