Re: [EnergyPlus_Support] Optimum Part Load Ratio

[Richard Raustad <RRaustad@xxxxxxxxxxxx>]

See the IO Reference document for a description of the Plant Loop Load 
Distribution Scheme.

Plant Loop Object:

Field: Load Distribution Scheme

This alpha field contains the Load Distribution Scheme Keyword. The Load 
Distribution Scheme selects the algorithm used to sequence equipment 
operation in order to meet the plant loop demand. Currently, two schemes 
are functional. SEQUENTIAL* *uses each piece of equipment to its maximum 
part load ratio and will operate the last required piece of equipment 
between its minimum and maximum part load ratio in order to meet the 
loop demand. OPTIMAL* *operates each piece of equipment at its optimal 
part load ratio and will operate the last component between its minimum 
and maximum part load ratio in order to meet the loop demand. UNIFORM 
evenly distributes the loop demand amongst all available components on 
the equipment list for a given load range.
