Performance comparison with effect of door opening on variable and fixed frequency refrigerators/freezers

Stochastic control of cooling appliances under disturbances for primary frequency reserves

“…The relative energy lost due to fridge openings is about 7 % to 30 % of the total energy consumption, this figure being higher for non-efficient cold appliances [17,18,19,20].…”

Analysis of effecting factors on domestic refrigerators’ energy consumption in use

“…Most of these studies focused on ambient temperatures and internal compartment temperatures, which are said to be crucial factors [14][15][16][17][18][19]. Also the number of door openings was in the center of interest of different previous studies [20][21][22][23][24]. However, most of the aforementioned studies were limited to investigate the influence of one single variable on refrigerators' energy consumption.…”

Scheduling a single machine with concurrent jobs for the frozen food industry

“…The frozen food is a case of multiple products that have varying processing times. The interruption costs of freezing are mainly from the cost of energy consumption (Liu, Chang, & Lin, 2004) and the food quality (Li & Sun, 2002). That is because freezing is one of the most energy consuming processes (Chourot, Macchi, Fournaison, & Guilpart, 2003).…”
