“…Clear from this figure is that the refrigerated cases energy consumption during the summer season is higher for all cities because of the higher humidity ratio present in the stores. The trend of the energy consumption of the display case cabinets is consistent with the field measurements conducted by Axell and Lindberg, who found that electrical consumption increased 55% during summer because of the variations in the ambient humidity [9]. Here with the utilization of solar dehumidification, the summer increases seen respectively in Dayton, OH, Phoenix, AZ, and Pine Bluff, AR were respectively 30%, 15%, and 26%.…”

“…In the base case model, the indoor relative humidity was set at 55%. This assumption permitted a comparison to a prior study [9], but in practice real stores see the relative humidity fluctuating throughout the year. The second limitation is that the savings and conclusions drawn are based upon theoretical analyses only.…”

Food deserts have emerged in underserved urban and rural areas throughout the United States. Corner markets have filled the food voids, but generally without offering residents access to healthy food. The economics for doing so are prohibitive. The purpose of the study is to investigate an opportunity for reducing corner store energy costs in order to make possible retail of fresh produce and meat. Given the typical dominance of refrigeration to the energy cost in such stores, an integrated solar dehumidification system with heating, ventilation, and air conditioning (HVAC) is considered. A typical corner store baseline reliant upon conventional refrigeration and HVAC equipment is defined to serve as a basis for comparison. MATLAB Simulink dynamic models are developed for the posed system and baseline model. The results show energy reduction in the refrigerated cabinets of maximally 28%, 27%, and 20%, respectively, in Dayton, OH, Phoenix, AZ, and Pine Bluff, AR. The respective HVAC energy savings are respectively 28%, 56%, and 4%. Collectively these correspond to total annual energy savings of 43%, 51%, and 53%, translating to annual energy cost savings of greater than $12K in all locations.

“…A review of the literature on experimental and numerical investigations of the performance of display cabinets was carried out by the authors (Chaomuang et al, 2017). An experimental study of heat transfer in a closed display cabinet was conducted and the effect of operating conditions on the product temperature was highlighted: room temperature, door-opening frequency and occupiedvolume percentage (Chaomuang et al, 2019a(Chaomuang et al, , 2019b.…”

Air velocity measurements were carried out using the Particle Image Velocimetry (PIV) technique in a display cabinet under two configurations: closed and open doors. Two conditions (refrigeration system turned "on" and turned "off") were studied in the closed configuration. The airflow pattern was almost the same for both conditions. The air curtain was quite stable. In the upper part of the cabinet, air recirculation occurred, and this phenomenon induces external air infiltration through the door gaps. The air curtain in the open configuration (refrigeration system turned "off") was less stable than the closed configuration. Large unsteady eddies developed in the mixing layers, thereby promoting greater external air infiltration. A two-dimensional computational fluid dynamic (2D-CFD) model was developed and showed the ability to reproduce the main flow phenomena observed in the experiment. The trend of predicted product temperature profile was also in agreement with the experimental values, despite slight underestimation.

“…According to available data, yearly energy demand of supermarkets varies in the range from 400-500 kWh/m 2 (in Netherland [32], UK [33], USA [32] and Italy [34]) to 700 kWh/m 2 (in USA and Canada [32]) with an incidence of refrigerating equipment of about 45% [33,35,36] which correspond to about 4% of global electricity consumption [23,37,38]. In addition, it is accepted that using doored refrigerated cabinets results in 30% of energy saving with respect to open vertical refrigerated displays [39,40].…”
