Heat Pump In this study, general five heat pumps were chosen with different capacities at Amman city and its climate conditions, it could be used for any building appropriate the capacity of any of these heat pumps, these heat pumps studied from energy and economical point of view. Table 4.1 shows these heat pumps and their capacities of cooling and heating in addition to required input work. Table ‎4.1 Heat pumps used in the study information Item HP1 HP2 HP3 HP4 HP5 Heating capacity (kW) 10.10 11.30 20.40 24.20 41.10 Cooling capacity (kW) 8.02 8.97 16.18 19.18 32.62 Input power (kW) 2.08 2.33 4.22 5.02 8.48 COP (Coefficient of Performance) 4.86 4.85 4.83 4.82 4.85 Refrigerant R407C R407C R407C R407C R407C Rated outlet hot water temperature (℃) 55.00 55.00 55.00…show more content…
So, the needed area 8.8 m2. Underground thermal energy storage (TES) tank Underground TES used to store thermal energy during sunny time, to avoid fluctuation of the water source of the heat pump temperature, which will keep the heat pump reliability and a good COP. To calculate the required volume of the tank to cover the requirements, could be calculated as below for the HP1: HP capacity = 10.1 kW, then for 24-hour operation with RHF 80% the heating capacity needed = 193.92 kWh. ETC-30 load = 193.92 kWh / 5.8 h (PSH) = 33.43 kW No. of ETC-30 panels = 33.43 kW / 1.852823 kW (peak load of one ETC-30 on December, Table 4.9) = 18.045 ~ 19 panel. According to Apricus their ETC-30 can provide 10.41oC difference between the inlet of the panel and its outlet at flowrate 2.5 L/min, then if the ETC-30 panels are connected in parallel and series connection to provide 50oC temperature
