Latent storage systems are suitable for refrigeration systems that have to cope with highly fluctuating load requirements throughout the day. If such systems were designed without storage, they would have to be dimensioned for peak demand. This would result in the cooling system being oversized. In addition, overall utilisation would be poor, as the refrigeration machine would only run at peak load for a fraction of the day.
In combination with BMS power® module technology, latent storage systems offer another advantage: they allow the system to be operated on a heat-led basis in the event of time-delayed heating and cooling requirements, and to store the cooling energy generated for later use. (An example of this would be heating a building on spring or autumn nights and air-conditioning its south side on sunny afternoons with the cold stored at night).
An ice storage system can be charged during off-peak periods and spontaneously supply large amounts of cooling during peak loads. This has several positive effects
This bundle of advantages opens up potential savings in refrigeration and air conditioning technology, for example in supermarkets, process cooling, food processing and the chemical and pharmaceutical industries.
Since ice storage eliminates the need to design the system for peak loads, investment costs are reduced not only in the area of refrigeration machines. Recoolers, electrical systems, fuses and much more can also be smaller. In addition, operating and maintenance costs are reduced, thus lowering operating costs.
Ice storage from Fafco, expertise from BMS
BMS-Energietechnik AG sources its ice storage tanks from Europe's leading manufacturer of ice storage tanks, FAFCO S.A. Thanks to our many years of experience, we can guarantee optimal integration of the ice storage tank into your system. We supply and calculate all the technology related to the ice storage tank. You receive a complete system solution – from a single source.
Like ice storage tanks, energy storage tanks with balls serve to decouple cold generation and consumption by storing thermal energy and releasing it at a later time as needed. However, a special principle is applied in this storage tanks. Energy storage is based on the melting heat principle and utilises the phase change of the storage medium: the medium to be frozen is contained in individual, airtight welded balls (hence the name of the storage system), which are charged or discharged by means of a carrier brine. The balls remain in the storage system, which thus forms a closed system.
The phase change principle allows very large amounts of energy to be stored in a small space. Thanks to the high storage capacity, even operators of refrigeration systems with limited installation space can generate cooling energy when electricity is cheapest. With an optimised design, cooling can be generated and stored exclusively at low tariffs.
The energy storage tanks with phase change material balls are available for different temperature levels:
0 °C, -3 °C, -6 °C, – 10 °C, -15 °C, -21 °C, -26 °C und -33 °C.
