Smart Control of Temperature Hysteresis in Cooling Systems
Smarter Energy Management through Precise Control of Temperature Range
Energy losses and unused storage potential in cooling
In some facilities, cooling is one of the largest energy expenses. Standard systems control cooling based on fixed temperature hysteresis, ignoring energy price fluctuations (like cheap night rates or SPOT market prices). This leads to frequent switching, higher costs, and a failure to use cold storage to its full potential – for instance, by "buying" energy when it's cheaper.
FLOWBOX Solution: Dynamic temperature control based on real-time and forecasted conditions
Intelligent Layer Above Existing Control Systems
FLOWBOX does not interfere with the control logic of the cooling system itself. Instead, it works as a smart decision-making layer that continuously monitors SPOT energy prices, thermal storage levels, and availability of on-site generation (e.g. from PV). Based on this data, it dynamically adjusts requests for switching cooling (or heating) systems on or off.
Dynamic Adjustment of Temperature Hysteresis
The system shifts and narrows the hysteresis band depending on current energy availability and cost. When energy is cheap, the band is narrowed closer to the lower temperature limit, pre-cooling the system (e.g. from 5–6 °C to 5–5.2 °C). When energy is expensive or during demand peaks, cooling is delayed or reduced by shifting the band upwards (e.g. to 5.8–6 °C) – still within the permitted operational range.
Result: Measurable Savings and Maximum Use of Cooling Storage Capacity
This smart control strategy delivers measurable energy savings of 10–20% on cooling consumption — without any changes to the existing infrastructure. It helps reduce demand peaks, improves the use of self-generated energy, and increases overall operational stability. Cooling thus becomes not just more efficient, but a fully integrated and intelligent part of the energy management system.
