|  | 1 | +# PERFORMANCEMAP | 
|  | 2 | + | 
|  | 3 | +PERFORMANCEMAP defines a multiple-dimension table of values from which models can derive performance data via interpolation.  Subordinate PMGRIDAXIS and PMLOOKUPDATA allow input of performance maps of a range of dimensions and granularity. | 
|  | 4 | + | 
|  | 5 | +Following ASHRAE Standard 205 terminology, sets of "grid" values are the independent variables and sets of "lookup" values are the dependent variables. | 
|  | 6 | + | 
|  | 7 | +The following example defines a 2D map based on grid variables outdoor dry-bulb temperature and (arbitrary) compressor speed.  For each grid value combination, lookup values are provided for capacity ratio and COP. | 
|  | 8 | + |

|  | 12 | +        PMGRIDAXIS "ClgSpeed" pmGType="Speed" pmGXValues=1,2,3 pmGXRefValue=2 | 
|  | 13 | + | 
|  | 14 | +        // Capacity ratio = net total capacity / net rated total capacity | 
|  | 15 | +        PMLOOKUPDATA LUClgCapRat pmLUType = "CapRat" pmLUValues = | 
|  | 16 | +          0.48, 1.13, 1.26,   // 60F at min, mid, max speed | 
|  | 17 | +          0.42, 1.05, 1.17,   // 82F | 
|  | 18 | +          0.39, 1.00, 1.12,   // 95F | 
|  | 19 | +          0.34, 0.92, 1.04    // 115F | 
|  | 20 | + | 
|  | 21 | +        // COP = net total COP | 
|  | 22 | +        PMLOOKUPDATA LUClgCOP pmLUType = "COP" pmLUValues = | 
|  | 23 | +          14.22, 16.44, 15.00,  // 60F at min, mid, max speed | 
|  | 24 | +          7.93,  7.59,  6.71,   // 82F | 
|  | 25 | +          6.01,  5.58,  4.91,   // 95F | 
|  | 26 | +          4.12,  3.82,  3.34    // 115F | 
|  | 27 | + | 
|  | 28 | +    endPERFORMANCEMAP | 
|  | 29 | + | 
|  | 30 | +At OutdoorDBT=95 and Speed=2, this performance map would yield CapRat=1.00 and COP=5.58.  At other (OutdoorDBT,Speed) combinations, suitable 2D interpolation is performed on each lookup variable.  Lookup variables are extrapolated outside of PMGRIDAXIS ranges; adequate axis ranges must be provided to avoid unrealistic extrapolation. |
