By placing the Eutectic products within the cold store one can create a TES facility whereby the excess refrigeration capacity during off-peak periods and lower ambient
conditions over-night can be utilised to shift the peak load.
Eutectic TES can either be installed as part of the cold store fabric for example hanging TubeICE on ceiling/walls or alternatively containers like FlatICE can be placed on pallets and stored with the shelves or alternatively using ice packs / pouches Eutectic TES can be incorporated as part of the packaging / palleting.
Although one may over-cool the stored products to create a small load shifting capability but utilising the Latent Heat Capacity of the Eutectic TES one can increase the thermal energy storage capacity by as much as 10~15 times for a given volume.
As the cooling load significantly varies over daily or weekly periods, Eutectic TES enables the operator to spread the load over a 24 hour period which in return offers the facility of running the refrigeration machinery during lower night-time ambient conditions to charge the Eutectic TES. Later during day-time / peak cooling periods this over-night stored energy can be utilised to top up the refrigeration load without the need for full load mechanical cooling.
Finally, a Eutectic TES is a static system i.e. no moving parts offering a full stand-by capability in case of any mechanical failures and offers a maintenance free back-up
facility.
By simply running the refrigeration machinery over night-time cooler ambient periods, one can save as much as 15~25% electricity consumption due to higher efficiencies of the refrigeration machinery at lower ambient condition as illustrated in this graph.
Reduced actual kWh electricity consumption coupled with the possible cheap off-peak electricity costs may reduce the overall cold store annual running cost by as
much as 30~50% depending on the region.
