CHAPTER 4: COMPARISON BETWEEN R-22 AND CO2 SYSTEM 89 4,1 System Setup In chapter 3 the method for deriving the formulas for a CO2 heat pump system in terms of COP and heating capacity was discussed. The same equations were derived by M Tech Industrial (pty) Ltd. for a heat pump system operating with R-22 as refrigerant. These equations are now implemented into the WHSIM Statistical program (Rousseau, 2006) which can be used to compare the two systems, and they are also compared to a system having only an ILH. The ILH system is also implemented in the programme used to determine the performance. The WHSIM Statistical program describes and predicts the performance and power consumption of a heat pump under any circumstances taking into consideration the location and weather and will be used to compare the three systems under the same given conditions. It is a software application containing weather data for certain areas in South Africa and different setup possibilities like for instance a hotel situation. The scenario surrounding the implementation of the three systems are given in Table 4.1. The program contains historic weather data of South Africa so the heat pump systems can be compared for every half hour over a period of a total year. 4,1.1 Scenario Table 4.1: Scenario for the system set up. 7900 litres Series 50kW used with heat pum s 48kW (on its own) The installation is set up with a typical hotel situation. It is set that the occupancy of the hotel is 190 persons and it is set that each person will use an average of 75 litres of hot A Techno-Economical Analysis ofa CO2 Heat Pump.
