  2. 1. Carbon Dioxide in Supermarket Refrigeration

    University dissertation from Stockholm : KTH

    Author : Samer Sawalha; KTH.; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CO2; carbon dioxide; refrigeration system; supermarket; cascade; indirect; trans-critical; modelling; simulation; experiment; safety analysis; comparison; TECHNOLOGY Engineering mechanics Mechanical and thermal engineering Mechanical energy engineering; TEKNIKVETENSKAP Teknisk mekanik Mekanisk och termisk energiteknik Mekanisk energiteknik;

    Abstract : This thesis theoretically and experimentally investigates different aspects of the application of CO2 in supermarket refrigeration. Theoretical analysis has been performed using computer simulation models developed to simulate CO2 indirect, NH3/CO2 cascade, CO2 trans-critical and direct expansion (DX) R404A systems. READ MORE

  4. 2. Supermarket food waste

    University dissertation from Stockholm : KTH

    Author : Mattias Eriksson; Sveriges lantbruksuniversitet.; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Food waste occurs along the entire food supply chain and gives rise to great financial losses and waste of natural resources. The retail stage of the supply chain contributes significant masses of waste. Causes of this waste need to be identified before potential waste reduction measures can be designed, tested and evaluated. READ MORE

  5. 3. Indoor thermal environment in Supermarkets : A study of measured and perceived comfort parameters

    University dissertation from Göteborg : Chalmers Reproservice

    Author : Ulla Lindberg; Högskolan i Borås.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal environment; supermarket; interdisciplinary; display cabinets; refrigeration systems; thermal comfort;

    Abstract : 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.
