70 : // AUTHOR Dan Fisher
71 : // DATE WRITTEN July 1998
72 : // MODIFIED June 2000 -Brandon Anderson
73 : // Changed to Group Similar Components. Components will
74 : // be defined by ComponentType:SpecificComponent.
75 : // The colon will act as the type delimeter, So all
76 : // components of one type will be grouped. ex.(Boilers,Chillers)
77 : // May 2003 - Simon Rees
78 : // Added initial loop to force free cooling chiller etc to be
79 : // simulated before other components.
80 : // RE-ENGINEERED na
81 :
82 : // PURPOSE OF THIS SUBROUTINE:
83 : // This subroutine calls the appropriate routines to simulate
84 : // the equipment on the plant.
85 :
86 : // METHODOLOGY EMPLOYED:
87 : // This subroutine employs a rule-based
88 : // scheme to operate the plant equipment simulation without
89 : // requiring a detailed flow network solver. The scheme is based
90 : // on several restrictive assumptions which may be relaxed when
91 : // a more detailed solution technique is developed. The current
92 : // assumptions are:
93 : // 1. All loop cooling/heating equipment is connected
94 : // in parallel.
95 : // 2. Only one circulation pump may be specified per loop.
96 : // 3. The circulation pump must be specified first in the
97 : // simulation order and is assumed to be connected in
98 : // series with the cooling/heating equipment.
99 : // 4. The Circ. pump determines the maximum flow rate for
100 : // the loop.
101 : // The scheme is valid only for Part Load based plant equipment
102 : // models (currently the only type implemented). Each equipment
103 : // simulation updates its outlet node temperature, estimates its
104 : // flow rate and returns a remaining loop demand which is passed
105 : // on to the other available equipment.
106 :
107 : // NOTE: All Equipment return the index of their lists during "InitLoopEquip"
108 : // as a time reduction measure. Specific ifs are set to catch those modules that don't.
109 : // If you add a module or new equipment type, you must set up this structure.
