Ice storage loading cycle
Charging process depending on the charging temperature
The graph shows the development of the average charging temperature, which is the average of the flow and return temperatures (Tv+Tr)/2.
- At an average charging temperature of -2.2 °C, the storage tank can be charged within 10 hours.
- At -3.4 °C, the charging time is already less than 6 h.
In the example, an average charging temperature of -4.5°C (-6.5/2.5°C) has been selected as the switch-off time (dashed line).
The diagram serves as a basis for planning. The storage units are always designed on a project-specific basis. Further adjustments to the loading time are possible and can be determined on a project-specific basis.
Discharge cycle ice storage tank
- The diagram shows the average discharge temperature (Tv+Tr)/2 as a function of the ice storage temperature. At a storage tank temperature of 0 °C, the full capacity is available. If the storage tank temperature rises above 0 °C, the latent storage tank is used up and the discharge capacity decreases.
- The diagram serves as a project planning aid. In the example (dashed line), an average discharge temperature of 8 °C (4/12°C) has been chosen as the design criterion.
Pressure loss
- The diagram shows the pressure loss of the standard storage tank variants as a function of flow rate.
- The diagram is intended as a planning aid. Exact values are always determined on a project-specific basis.
- The design of the heat exchanger achieves low pressure drop at high capacity, resulting in high efficiency and economy.
