This is a retrofit application since the cooling and heating systems are already in place. Currently installed CO2 heat pump system prototypes have not been designed to provide such high load. Hence, the initial cost of this system is difficult to predict. Figure 5-2 shows the achievable pay back period with change in the initial cost of the system. Commercial production of CO2 heat pump system is expected to lower the initial cost and thus, decrease the payback period. With commercialization of the system will make the system more feasible. Figure 5-2. Variation of payback period with initial cost of the system. 5.1. Payback Analysis with Storage Subchapter 3.4 discusses the advantages of including Thermal Energy Storage (TES). Integration of daily TES increases the energy savings to 33.2% from 27.8%. Cost of a standard water storage tank of ~37 m3 is estimated to be $13,500 (State of Michigan, 2015). This cost is the average cost of the factory coated, bolted steel surface reservoirs erected on sand or gravel with a steel ring 44PDF Image | CO2 HEAT PUMPS FOR COMMERCIAL BUILDING APPLICATIONS
