1. 1. Vertical Display Cabinets in Supermarkets - Energy Efficiency and the Influence of Air Flows

   Författare :Monica Axell; RISE; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; display cabinet; model; simulation; supermarket; CFD; air curtain; energy; performance; air distribution; display case; infiltration;

   Sammanfattning : This thesis concerns investigations of the performance of vertical refrigerated display cabinets. Such cabinets are in widespread use and account for a considerable proportion of the energy used in shops. The open front is important for the shop-owner, who wants the chilled items in the cabinet to be well exposed and easily accessible. LÄS MER

3. 2. Indoor Thermal Environment in Supermarkets. A study of measured and perceived comfort parameters

   Författare :Ulla Lindberg; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigeration systems; supermarket; display cabinets; thermal comfort; thermal environment; interdisciplinary;

   Sammanfattning : In the supermarket environment three different groups must be considered: food (food quality), personnel (working conditions) and customers. Customers are of particular interest since they make up the commercial basis for the supermarket. Currently, however, there are no recommendations on the indoor environment for this category.

4. 3. Exploring barriers to energy efficiency in supermarkets

   Författare :Ulla Lindberg; MariAnne Karlsson; Högskolan i Borås; []
   Nyckelord :retail; servicescape; foodscape; chilled groceries; energy efficiency; barriers; refrigerated display cabinets; consumer behaviors; consumer perceptions; Resource Recovery; Resursåtervinning;

   Sammanfattning : Energy efficiency activities in sections of grocery stores for chilled groceries are subject to particular challenges as this is a complex indoor environment given that the goal of store owners is to offer consumers chilled groceries of high quality in a comfortable environment while at the same time trying to reduce energy use. Consequently, it is important to maintain the right temperature in the right place and to be aware of the consumers’ shopping situation. LÄS MER

5. 4. Supermarket refrigeration systems for demand response in smart grids

   Författare :Tommie Månsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supermarket; Demand-side management; Smart-Grid; Energy efficiency; Food retail; Demandresponse; Thermal modelling; Refrigerated Display Cabinet; Renewable energy;

   Sammanfattning : With an increasing share of intermittent renewable energy sources in the electrical grid, the need for adapting the demand to the available supply of electricity becomes increasingly important. Within this thesis, the demand response capacity by supermarket refrigeration systems are investigated and methods for enabling it is developed. LÄS MER

7. 5. Energy in supermarkets - An overview on the energy flows and refrigeration controls

   Författare :Tommie Månsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The electrical energy used by supermarkets represents approximately 3% of Sweden's annual energy use. Of this, the refrigeration system accounts for 50%. To reduce greenhouse gases introduced by energy generation, a larger share of renewable energy sources must be implemented. LÄS MER
