This study proposes a new type of dual-source building energy supply system with heat pumps and energy storage, which combines WSHP, ASHP, PV/T modules, and energy storage tank efficiently. The system can use the low-temperature hot water generated by PV/T modules or ASHP as the low-temperature heat source of WSHP.
For chilled water TES, the storage tank is typically the single largest cost. The installed cost for chilled water tanks typically ranges from $100 to $200 per ton-hour,12 which corresponds to $0.97 to $1.95 per gallon based on a 14°F temperature difference (unit costs can be lower for exceptionally large tanks).
