Integration of the hidden refrigeration capacity as heat pump in smart energy systems
Discover the potentials of extending the traditional supermarket refrigeration systems to a wider energy context consisting of flexibility enabled electrical and thermal networks. Supermarket systems can become decentral heat producers and export heat to available thermal networks beyond the normal waste heat recovery by utilizing present 70% stand-still capacity in the systems. This capacity can further be utilized to help balance the production/load on the electricity grid by an efficient conversion from electricity to heat, when the production from renewable sources like e.g. wind surpass the immediate consumption. Investigations are based on real supermarket cases and technology choices in the aspect of low GWP refrigerants are evaluated. Barriers like electricity prices versus system COP and framing conditions like Thermal network temperature lift is evaluated and a method of optimizing is suggested.

Opportunities from rethinking refrigeration system architecture in retail
This presentation looks at a cooperation between Emerson and a supermarket chain where both companies worked together to understand what is the best refrigeration system option for a 2000m² supermarket. Various system architectures (centralized system, condensing unit, integrated display cases) are assessed from the view of the supermarket chain, in terms of energy efficiency, investment cost, and other operating criteria that eventually even impact overall business performance.

Adiabatic CO2 gas coolers – Smart efficiency (also) in hotter climates
This lecture explains the advantages of adiabatic air pre-cooling applied to gas coolers for transcritical CO2 (supermarket) plants. Based on a practical example, the participants will be introduced to smart control functions ensuring lowest operating costs. What’s more, the different connection options of the Controller to superordinate BMS will briefly be presented.

Transcritical CO2 condensing unit driven by DC inverter technology for small format stores
Carel is promoting a new solution for CO2 condensing unit with DC inverter compressors in order to accelerate the introduction of carbon dioxide in this segment and to comply with the main regulations addressed to the low ambient impact both direct using low GWP refrigerants and indirect focusing on high energy efficiency systems. This speech informs about the results achievable with this control solution and its adaptability even in warm climates.
