## 2 Materials and Methods  
The schematic diagram of the reference cycle [22] is given in Figure 1.  
Figure 1: Schematic diagram of the reference cycle [22]. P-h and T-s diagrams illustrated in Figure 2 demonstrate the processes in the reference cycle. This cycle integrates a power cycle with a refrigeration cycle. The working fluid in the cycle is separated into power cycle stream and refrigeration cycle stream after the condenser. In the power cycle part, the working fluid is compressed by the pump, then receives heat from geothermal source at the ORC evaporator and is expanded by a turbine which generates power. In the refrigeration cycle part, the working fluid is expanded to the pressure levels of the medium temperature (MT) evaporator and the low temperature (LT) evaporator. The working fluid receives heat from food preservation cabinets by evaporation. After leaving the MT evaporator, the working fluid is expanded to the LT evaporator pressure. Then, streams coming from the MT evaporator (\(\dot{m}_{12}\)) and the LT evaporator (\(\dot{m}_{10}\)) are mixed (\(\dot{m}_{13}\)) before entering the compressor. Finally, power and refrigeration cycle streams are mixed to condense at condenser. Then, the cycle continues. Figure 3 shows the schematic diagram of the proposed novel cycle. P-h and T-s diagrams of the proposed novel cycle are given in Figure 4.  
In the proposed novel cycle, which also integrates a power cycle with a refrigeration cycle, the working fluid in the cycle is separated into power cycle flow and refrigeration cycle flows after the condenser like the reference cycle. The operation at the power cycle part is exactly same as the reference cycle (compression at pump, heat absorption at ORC evaporator and expansion at turbine). In the refrigeration cycle part, the working fluid is split into two streams forming two sides of the heat exchanger (HEX). Expanded to the MT evaporator pressure between Point 7 and Point 15, the cold side of the heat exchanger receives heat from the hot side and the working fluid leaves the heat exchanger as saturated vapor at Point 16. On the other side of heat exchanger, the working fluid loses heat to provide lower quality at the inlet conditions of evaporators. Then, the working fluid is expanded to the pressure levels of the medium temperature (MT) evaporator and the low temperature (LT) evaporator for refrigeration process. After leaving the LT evaporator, the working fluid is compressed at Compressor 1 (Comp\({}_{1}\)). Then, firstly, stream coming from the MT evaporator and Comp\({}_{1}\) are mixed (Point 14). Secondly, the streams from the cold side of the heat exchanger and Point 14 are mixed before entering Compressor 2 (Comp\({}_{2}\)). Finally, the power and refrigeration cycle streams are combined before entering the condenser, and the cycle continues. Figure 2: (a) P-h diagram of the reference cycle; (b) T-s diagram of the reference cycle [22]. Thermodynamic modeling has been made by the Engineering Equation Solver (EES) [32]. All analyses performed in this study were conducted in accordance with the conservation of mass and energy laws. To clarify the processes in the proposed novel cycle, the application of the conservation of mass law is presented in Equations (1) and (2). \[\dot{m}_{14}=\dot{m}_{12}+\dot{m}_{13} \tag{1}\]  
\[\dot{m}_{7}=\dot{m}_{3}+\dot{m}_{8}+\dot{m}_{15} \tag{2}\]

Energy balances at mixing points are given in Equations (3)-(5). \[\dot{m}_{14}h_{14}=\dot{m}_{12}h_{12}+\dot{m}_{13}h_{13} \tag{3}\]  
\[\dot{m}_{17}h_{17}=\dot{m}_{14}h_{14}+\dot{m}_{16}h_{16} \tag{4}\]
