Abstract
Refrigerant pressure in the condenser unit of a chiller is monitored relative to a real time alarm limit for the refrigerant pressure. The real time alarm limit is computed from time to time by a microprocessor. The value of the computed alarm limit will vary with the cooling load being experienced by the chiller's evaporator unit.
