+Model of an organic Rankine cycle (ORC) as a bottoming cycle. +

+

+The thermodynamic cycle is steady-state while the evaporator and the condenser +can be configured to have first order dynamics. +The fluid stream 1 (using Medium1, port_a1, etc.) +is the evaporator hot fluid, e.g., waste heat, +and the stream 2 is the condenser cold fluid. +The working fluid of the cycle is not based on a typical Modelica medium model. +See the Thermodynamic Properties section of this document for the rational. +

+

Cycle Architecture and Governing Equations

+

+The implemented ORC is modeled based on the simplified cycle shown in the figure below. +The cycle has two variants depending on the shape of the saturation lines of +the working fluid and ηexp. +For any given working fluid, the cycle is fully determined by providing +the working fluid evaporating temperature Tw,eva, +the working fluid condensing temperature Tw,con, +the expander efficiency ηexp, and +the pump efficiency ηpum. +The superheating temperature difference ΔTsup +is minimized, meaning it is zero whenever possible; otherwise it assumes +the smallest value not to cause the expander outlet state to fall +under the two-phase region, i.e. the \"dome\". +Subcooling after the condenser is not considered. +The Thermodynamic Properties section of this document details how these +state points are found. +

+

+An important assumption is that all heat is dissipated, i.e., +the cycle is not controlled by thermal load. +

+

+

+

+The cycle processes the heat at a fixed +Tw,eva provided by the user. +The evaporator heat exchange is governed by +

+

+Q̇eva = ṁh cp,h (Th,out - Th,in),
+Q̇eva = ṁw (hpum,out - hexp,in), +

+

+where the subscripts are +eva for evaporator, +exp for expander, +h for hot fluid of the evaporator, i.e. the fluid carrying heat, +pum for pump, and +w for working fluid. +

+

+The cycle accommodates the variable flow rate and temperature +of the waste heat stream by changing the working fluid mass flow rate ṁw +to maintain a constant pinch point (PP) temperature difference +at the evaporator ΔTpin,eva. +This difference is found from +

+

+(Tpin,eva - Th,out) (hexp,in - hpum,out) += (Th,in - Th,out) (heva,pin - hpum,out),
+ΔTpin,eva = Tpin,eva - Tw,eva. +

+

+The condenser side uses the same equations with the evaporator variables +replaced by their condenser counterparts where appropriate. Hence, +

+

+Q̇con = ṁc cp,c (Tc,out - Tc,in),
+Q̇con = ṁw (hpum,in - hexp,out),
+(Tc,pin - Tc,in) (hexp,out - hpum,in) += (Tc,out - Tc,in) (hcon,pin - hpum,in),
+ΔTcon,pin = Tw,con - Tc,pin, +

+

+where the subscripts are +con for condenser, and +c for cold fluid in the condenser.
+

+

+The electric power output of the expander is +

+

+Pexp = ṁw (hexp,in - hexp,out). +

+

+The electric power consumption of the pump is +

+

+Ppum = ṁw (hpum,out - hpum,in). +

+

+The pump work is +

+

+Ppum = ṁw  +(peva - pcon) / (ρpum,in ηpum). +

+

+This takes advantage of the negligible density change of the liquid +to avoid a property search in the subcooled liquid region. +

+

+In summary, the model has the following information flow: +

+ + + + + + + + + + + +
User-specified parametersInputsOutputs
+Tw,eva - Working fluid evaporating temperature,
+ΔTpin,eva - Evaporator pinch point temperature difference,
+ΔTpin,con - Condenser pinch point temperature difference,
+ηexp - Expander efficiency,
+ηpum - Pump efficiency. +		 +Th,in - Evaporator hot fluid incoming temperature,
+ṁh - Evaporator hot fluid flow rate,
+Tc,in - Condenser cold fluid incoming temperature,
+ṁc - Condenser cold fluid flow rate. +		 +ṁw - Working fluid flow rate,
+Tw,con - Working fluid condensing temperature,
+Th,out - Evaporator hot fluid outgoing temperature,
+Tc,out - Condenser cold fluid outgoing temperature,
+Q̇eva - Evaporator heat flow rate,
+Q̇con - Condenser heat flow rate,
+Pexp - Expander power output,
+Ppum - Pump power consumption. +
+

Constraints

+

+The ORC system controls ṁw to maintain the prescribed +evaporator PP temperature difference set point. +Although the model does not implement this as a control loop, +an upper limit and a lower limit are imposed on +ṁw to reflect the capacity constraints of a sized cycle. +

+ +

+How these constraints affect the cycle's behavior reacting to +a variable waste heat fluid stream is demonstrated in + +IBPSA.Fluid.CHPs.OrganicRankine.Validation.VariableSource. +

+

Thermodynamic Properties

+

+The thermodynamic properties of the working fluid are not computed by a typical +Modelica medium model, but by interpolating data records in + +IBPSA.Fluid.CHPs.OrganicRankine.Data. +Specific enthalpy and specific entropy values are provided as support points +on the saturated liquid line, the saturated vapor line, and +a superheated vapor line (called the reference line). +The values of these support points were obtained using CoolProp +(https://www.coolprop.org; +Bell et al., 2014) through its Python wrapper and stored as Modelica records. +An example Python file is provided in +IBPSA/Resources/Python-Sources/MakeORCFluidRecord.py, +but note that this file is not maintained. +The records included in this library have ten data points for each line. +It is recommended to have at least four points to take full advantage of +the cubit Hermite spline interpolation that is set up in this model. +

+

+Thermodynamic state points in the cycle are determined by various schemes +of interpolation and extrapolation. +

+

+

+ +

+The cycle can be completely defined by providing the following quantities: +evaporating temperature Teva or pressure peva, +condensing temperature Tcon or pressure pcon, +expander efficiency ηexp, and +pump efficiency ηpum. +Most of the important state points can be found via the interpolation schemes +described above. The only exceptions are the expander inlet, expander outlet, +and the pump outlet. +

+

+

+ +

Implementation

+The user can parameterise the evaporating condition by providing either the +evaporating temperature TWorEva or the evaporating pressure +pWorEva. To support this, a default parameter assignment is +provided to both. Otherwise there would be unassigned parameters even though +they are not needed. +
