Ice Bank

Ice Bank with a constantly large ice surface

An Ice Bank with a constantly large ice surface allows you to cool the product as quickly as possible despite peak loads. Ice storage enables high cooling consumption peaks to be handled even with refrigeration systems that are only designed for the daily average value. The advantage of an Ice Bank is the high cooling capacity for the reduction of peak cooling loads, which can be provided with relatively small refrigeration systems, because they must be designed only for the average load. For the best possible quality of food and dairy products, the cooling performance at peak loads must not break. Ice grants the maximum power reserve and safety.

Operating cost efficiency

The operating cost efficiency of the ice storage is based in particular on the ability to either use low-priced night power, often costs only half compared to the normal tariff or limit the maximum power requirements, because this determines the base price of the electricity supplier. On the other hand, Falling-Film Chillers are much cheaper and, in addition to lower energy consumption, they also require less space. The clear advantage of an Industrial Ice bank in the past in the use of partial load operation has gradually changed over the last few years and has been differentiated by the fact that Falling-Film Chillers can be also used in partial load operation in case of fluctuations in water temperature or quantity.

Ice Bank Storage Mode

How does an Ice Bank work?

Storage mode or ice buildup: In the static ice storage, the evaporator plates are in an open tank filled with water, i. A. in a rectangular tank. Ice freezes, depending on the storage time at an evaporation temperature of -4 to -10 ° C on the vertical plates to a homogeneous layer of up to 55 mm, which firmly adheres to the plates. (static ice storage).

Cooling operation or defrosting phase: The heated return water is distributed via a system of pipes arranged on the bottom of the tank, which ensures homogeneous defrosting of the ice. An air recirculation pipes at the bottom of the tank creates strong turbulence and ensures a very effective heat transfer and thus very low ice water temperatures. The air circulation is energy-saving only when needed, but then automatically. The ice surface is advantageously identical to the plate surface and remains constant until the end of defrosting, which ensures a very high, constant cooling performance.
