Abstract: Radiator types may affect the drying method or drying speed. Experiments to investigate the effect of a radiator type on a room temperature distribution and heat transfer rate were conducted. There were three radiator types used in this work, i.e., parallel radiator (Case A), finned radiator (Case B) and serpentine radiator (Case C). The prototype room with an overall size of was made of plywood and employed in this study while the radiators were made from copper pipes and aluminium fins. The water temperature at the entrance was increased gradually at 0 to 1000s and then kept at 80°C. The maximum temperature of 50°C was reached in the prototype room and shown by the closest thermocouple to the radiator. In general, Case A is the best radiator type and recommended as a heat source in a dryer room. |
