Seasonal thermal energy storage system

摘要

A seasonal thermal energy storage system for heat supply and removal, including an energy-storage device, a solar collector, a refrigerating unit, and a water supply device in closed-loop connection to a user terminal. The energy-storage device includes at least a heat source storage pond and a cold source storage pond. The heat source storage pond and the cold source storage pond are connected to water source via first water pumps. The water supply device includes a hot water supply pool connected to the heat source storage pond and a cold water supply pool connected to the cold source storage pond. The solar collector is connected to the heat source storage pond and the hot water supply pool via second water pumps. The refrigerating unit is connected to the hot water supply pool and the cold water supply pool via third water pumps.
