“…With the formation of the air jet effect in the air curtain, the packages 7 and 8 given in Figure 3 with the highest package temperatures were kept within the temperature range required by the standard. Zhijuan et al (2013) examined the relationship between cooled package temperature and environment. They noted that when the velocity of the air curtain increased by 0.15 m/s, there was a decrease in the temperature of the packages by 0.2 °C ~ 1.1 °C [16].…”

Air flow is of great importance in terms of energy efficiency and homogeneity of the cooled package temperatures in open type refrigerated display cabinets (RDCs). Deflectors are critical components for air curtains which are provides air directioning to air channel and grill. A new deflector structure was investigated to increase the performance of the air curtain in this study. Current design deflector structure (Design 1) and new design deflector structure (Design 2) were compared for temperatures of air off-air on and energy consumption parameters. Airflow in the new design deflector structure was tested under Class-3 conditions (25 °C temperature and %60 relative humidity) with ISO 23953-2 2015 standard. According to the results obtained the data compared with the current design deflector structure. The thermal performance has been increased by reducing the temperature of the air off by 1.2 °C on average, the air on temperature by an average of 2.05 °C and the average package temperature by %17.8 with the new deflector design. Cooling performance was increased using new deflector structure with effective airflow between the air off and air on. In addition, thanks to Design 2, the annual energy consumption of RDC has been reduced by 10.17% and accordingly the CO2 emissions released to the environment have been reduced at the same rate.

“…Despite there were no significant differences between mean thermal sensation votes (TSV) expressed by men and women, from the analysis of the distribution of votes and the percentage of dissatisfied calculated according to Fanger's approach (percentage of persons who voted ±2 and ±3 [11,73]) women appeared more unsatisfied. Particularly, in C1 (D1) PD F value for women was 10% (22%) instead of 0% (13%) in case of men.…”

The freezer system on ships involves provisions where meat, fish, vegetables etc. are cooled down. Provision room is one of the essential features on ships for the preservation of food. The size of the cooling chamber varies according to the length of the ship and the number of personnel. Under the scope of the study, a room with volume of 15 m 3 (H x L x W, 2.5 x 3 x 2 m.) has been designed for the preservation of the meat. Boundary conditions which are determined for numerical and theoretical analysis in provision room have been chosen considering existing ship conditions. Refrigeration load, temperature distribution and flow streamline to keep the meat at the desired temperature in the provision room have been analyzed for one hour working period. Within this time interval, average meat domain and air temperature drop have been found as 4.33 K and 13 K, respectively. CFD analysis and theoretical calculation results have been compared. The results have found to be in agreement with acceptable errors less than 10%. The outputs from analysis show that refrigeration unit provides suitable temperature decrease within determined time interval.
