High Suction super heat and Low discharge super heat

[Ashok2005]

Hi friends, We are having Macuay Chiler PEH 100 using refrigerant 134a
Please advise me the probable reasons for:-
1) High Suction Super heat.
2) Low Discharge Super heat.
Thanks.

Seriously?
At least give us some data to go on.
Pressures and all the relevant temperatures would be a good start.

Sensors ok? would expect high discharge superheat if suction is high too, but i am not familiar with chillers.
