A Study on The Three-Dimensional Temperature and Velocity Fields of Natural Convection Heating Systems for Mobile Home

Abstract

This study explores the use of natural convection heating in mobile homes by embedding panels in the walls that utilize hot water to supply thermal energy. It implemented natural convection heating with the thermal energy supplied by hot water by embedding natural convection panels in the walls of a natural convection heating system for mobile homes. The size of the natural convection heating system for mobile homes is 1800 mm wide, 1100 mm long, and 2100 mm high. The results of three-dimensional temperature and velocity fields inside the mobile home in this study showed uniform three-dimensional temperature and velocity fields resulting from the natural convection heat transfer inside the mobile home, and the temperature fields were shown to be well-being temperature fields beneficial to health. It was verified that heating is achieved by natural convection heat transfer, which is beneficial to health. In mobile home heating, the experimental natural convection heat transfer value and the theoretical natural convection heat transfer value of the air for heating matched relatively well in the entire range of the experiment. In addition, as the mass flow rate of hot water increased, the air temperature inside the mobile home rose. Therefore, as the hot water flow rate increased, the heating performance of the mobile home improved.
