The systems control components like the expansion valve is more expensive because of the higher pressures at which the CO2 is operating. Because of the higher pressure the pipes would also be more expensive because they should be able to withstand higher pressures than what is necessary for the R-22 system, but the cost difference is not that big because the CO2 is able to operate with smaller diameter pipes than the R-22 system which lowers the cost again. 2 , ()(X), ()(X).OO 1,800,()(X).oo , 1,600,()(X).oo 1i' c 1.4OO.()(X).00 t) ( Ql .!! :J ~ 3 1ii Figure 5.6: Present value vs. Life expectancy. 0.00 0 2 4 6 8 10 12 Year Figure 5.6 shows the present value cost of the systems over a period of ten years and depicts the life expectancy of the three systems. Each system's capital cost was implemented in year one including the operating cost of the first year and thereafter the accumulated operating cost is shown with the increase in tariff rates as previously mentioned. When comparing Figure 5.6 with Figure 5.5 the effect of capital cost on a system's life cycle cost can be seen. The ILH system has a low capital cost and therefore will be the less expensive choice to install when conSidering the first year of the system's life. However, it can be seen that just before two years the ILH system will A Techno-Economical Analysis of a CO2 Heat Pump.
