3 Terms and Definitions
GB/T 40104 and the following terms and definitions apply to this document.
3.1
A solar thermal power generation heat storage system in which the heat storage medium and the heat absorption medium are different media. Including the heat transfer fluid in the collector field entering the charging and discharging heat exchange
Heat transfer fluid piping within the piping interface of the equipment, as well as all process systems and equipment related to the heat storage medium.
3.2
A solar thermal power generation heat storage system in which the heat transfer fluid and the heat storage medium are the same medium. Including the heat transfer fluid outlet of the collector system to the heat storage system
System all involved process systems and equipment to the boundary where the heat transfer fluid releases heat and returns to the heat collection system.
3.3
The total mass of the heat storage medium that can participate in the charging and discharging process.
Note. The unit is kilogram (kg).
3.4
heatchargepower
The net heat flow into the heat storage system per unit time.
3.5
heatdischargepower
The net heat flow out of the heat storage system per unit time.
3.6
Heat storage depth storagelevel
The ratio of the available heat that can be provided by the complete heat release of the heat storage system to the design heat storage capacity.
