A Study on the Cooling Load of Small Cabins for One Person

Abstract

This study was conducted to lay cold water panels inside the ocher walls of a small cabin for one person and install cold water tubes inside the cold-water panels for radiant cooling with the absorption of thermal energy by the cold water for the first time at home and abroad. One-person households are increasing, and the current number of one-person households is about 5.61 million, accounting for 28.6% of all households. One-person households are still gradually increasing. However, study reports on small cabins for one person are rare at home and abroad. Therefore, this study was conducted to examine the sizes of beds for small houses for one person, which can be utilized as beds at normal times and can be used to take cold pack at home by those who like cold pack in hot summer. The findings of this study, which include the results of simulations of changes in the flow rate of the cold water circulating in the cold water panels of small cabins for one person and the distribution of the temperatures of the air inside the small cabins for one person in relation to changes in the outdoor temperatures in summer, indicated that the air temperature inside the small cabins for one person was linearly reduced by the radiative heat transfer and that well-being low-temperature distributions beneficial to health were shown.
