Design of refrigeration systems for grocery stores based on best technology

Aim and goal
Evaluate how to design three different refrigeration solutions in grocery stores in order to reach highest possible efficiency with focus on the technical potential.

Challenge
In order to meet the requirements of the new F-Gas Regulation, a large part of the rebuilding will take place in existing food premises. When it comes to eco design, EU rules set requirements for energy-efficient components, but do not include system solutions, which means that a system of energy-efficient components can still be ineffective if it is constructed incorrectly. Many of today's cooling systems are not energy efficient, but there is potential for efficiency. There is an opportunity to construct and install energy efficient cooling systems in conjunction with the rebuilding.

Solution
To propose the best possible system solution to cover the grocery store's refrigeration and freezing needs. Demonstrate how a system solution can be designed to interact with the building's heating system in order to recover heat. The solution refers to both systems and components.

Effect
To provide knowledge about the best possible technology for designing the refrigeration systems and dissiminate  the knowledge widely to grocery stores in order to accelerates the development towards a larger proportion of energy efficient food premises. By doing so, the project contributes to combating climate change by increasing the proportion of grocery stores with efficient cooling systems that extract less electricity and use low-carbon refrigerants.
