Supermarkets, Indoor Climate and Energy Efficiency - Field Measurements Before and After Installation of Doors on Refrigerated Cases
Year: 2008
Type: conference-paper
Abstract: Supermarkets are large users of energy and approximately half the electricity use derives from the display of refrigerated food.Ambient climate influences the performance of the cabinets and their energy use as well as the thermal comfort of people and the temperature quality of the food.An increase in temperature and humidity will raise the energy requirement for display of chilled and frozen food.Energy savings through energy efficient systems should not affect people or foodstuffs negatively.This paper presents field-measurements on the indoor climate, energy and impact on people and foodstuffs before and after glass doors have been installed on vertical display cabinets (retrofit).The results show that if the systems were optimized the installation could be even more energy-efficient.Less power consumption is possible for the refrigeration system as well as the other systems.
