The work was completed under ASHRAE Research Project 1467-RP Balancing Latent Heat Load between Display Cases and Store Comfort Cooling. The overall objective is to provide a comprehensive assessment of the potential for energy savings in supermarkets by optimized design and operation of the combined HVAC and refrigeration systems. The research addresses the impact of supermarket design, HVAC and refrigeration system design, temperature and humidity setpoints, and store location. The study uses EnergyPlus as the simulation tool for modeling supermarkets, and generally found good agreement with both measured results and expected outcomes on an individual variable level.
