It has to be noted that in the code in EES the nomenclature is a bit different that in the theory section. Specifically:  1’ is 1.5  3’ is 3.35  3’’ is 3.7 "Input data" {----------------------------------------------------------------------------------------------------------------------} {m_dot_water} {m_dot_brine} {rho_water} {cp_water} {rho_brine} {cp_brine} {delta_T_sub} {delta_T_sup} {T_brine_in=0} {input in {input in {input in {input in {input in {input in {input in {input in {input in parametric table, parametric table, parametric table, parametric table, parametric table, parametric table, parametric table, parametric table, parametric table, from experimental data Thermia} from experimental data Thermia} from experimental data Thermia} from experimental data Thermia} from experimental data Thermia} from experimental data Thermia} from experimental data Thermia} from experimental data Thermia} from Standard} {m^3/s} {m^3/s} V_dot_water=m_dot_water/rho_water V_dot_water_per_hour=V_dot_water*3600 V_dot_brine=m_dot_brine/rho_brine V_dot_brine_per_hour=V_dot_brine*3600 T_water_out=0.0036*T_amb^2-0.8342*T_amb+38.391 {T_water_out=0.0007*T_amb^2-0.3233*T_amb+27.579} Rho_1=Density(R410A,h=h_1,P=P_evap) Rho_1.5=Density(R410A,x=1,P=P_evap) Rho_2=Density(R410A,h=h_2,P=P_evap) Rho_m=(Rho_1+Rho_2)/2 Rho_3=Density(R410A,h=h_3,P=P_cond) Rho_3.35=Density(R410A,x=1,P=P_cond) Rho_3.7=Density(R410A,x=0,P=P_cond) Rho_4=Density(R410A,h=h_4,P=P_cond) {Cp_1=Cp(R410A,h=h_1,P=P_evap)} Cp_1.5=Cp(R410A,x=1,P=P_evap) Cp_2=Cp(R410A,h=h_2,P=P_evap) Cp_3=Cp(R410A,h=h_3,P=P_cond) {Radiator heating} {Floor Heating} -ii-

CO2 Organic Rankine Cycle Experimenter Platform The supercritical CO2 phase change system is both a heat pump and organic rankine cycle which can be used for those purposes and as a supercritical extractor for advanced subcritical and supercritical extraction technology. Uses include producing nanoparticles, precious metal CO2 extraction, lithium battery recycling, and other applications... More Info
