Review of thermal comfort design based on PMV/PPD in cabins of Korean maritime patrol vessels

This study has focused on the evaluation of the optimal temperature in each cabin of the Korean maritime patrol vessels. We aptly modified the inland indoor items and criteria of clothing and activities, and then investigated the human factors in the cabins of Korean maritime patrol vessels. The total thermal resistance of clothing in the wheelhouse was 0.097, 0.079, 0.096, and 0.130 m 2 °C/W and that for the accommodation areas was 0.067, 0.059, 0.084, and 0.101 m 2 °C/W in spring, summer, fall, and winter, respectively. The metabolic rate was 228.04 W/m 2 in the training room and above 100 W/m 2 in the engine room and auxiliary machine room. In the wheelhouse and accommodation, the metabolic rate was 78.14 and 44.45 W/m 2, respectively. Based on human factors, the optimum temperature was 23 °C in the wheelhouse and 29 °C in the accommodation. Therefore, 6 °C of energy can be saved in case of PMV/PPD-based air conditioning.
