CHAPTER 3. RESULTS AND DISCUSSIONS The annual data was input into the model discussed in Chapter 2 to derive various results discussed below. Figure 3-1 shows that annual potential energy savings of 15% can be achieved when a simple single stage compression transcritical CO2 cycle with a throttling valve is simulated. Figure 3-1. Potential primary energy savings. Various system alterations which were simulated to increase the overall efficiency of the system are discussed in the following subchapters. 3.1. Two-Stage Compression in Summer Months The system performance greatly depends on the ambient temperature. From Figure 3-1, it is evident that the system does not perform well in the summer 26
