CHAPTER 3: PUMP SIMULA TION MODEL A system working with a transcritical CO2 compressor won't have a conventional condenser but will rather have a gas cooler that cools down the compressed CO2 (Dorin, s.a.). Therefore it must be known that the global efficiency of the system will depend on how good the heat transfer is in the gas cooler and thus the gas cooler should be designed accordingly. A higher refrigerating capacity will be found for a lower gas cooler outlet temperature. Table 3.1 shows the compressor performance for the TCS362-D compressor that will be used in the system simulation. Table 3.1: Performance chart for the TCS3S2-D compressor (DORIN, s.a.).
