Peltier, Mattress, A Water Temperature Control SystemAbstract
This study aims to develop a water temperature control system for developing of temperature control mattress. In this step of study was designed a water temperature control system to get temperature control mattress prototype, that useful for quality of sleep in aging. The experiment in this study had examined the thermoregulation ability of the thermoelectric modules (peltier) for water temperature control. The 2 types of peltier were (1) TEC12706 and (2) TEC12712, which consisted of 4 scenarios. Scenario 1: experiment to study suitable peltier types for this application. Scenario 2: experiment to study the stored energy in water and peltier. Scenario 3: experiment to study the cooling ability of the developed system to the mattress. Scenario 4: experiment to study the heating ability of the developed system to the mattress. For all experiments, temperature of water at various locations were recorded to calculate the energy that the system could absorb and release using the peltier equations. The results showed that when supply electricity to peltier, hot water temperature rises and cold water temperature drops. The using of peltier TEC12712 resulted in a reduction in the time required to achieve the desired temperature for hot and cold water compare with TEC12706. Because of higher current and voltage were supplied to the TEC12712 peltier, resulted in increasing the released energy and absorbed energy of the peltier. In study the changing of stored energy in water and peltier energy revealed that the released energy and absorbed energy of peltier were agreed with the changing of store energy in water in both hot side and cold side. However, the changing of stored energy in water was less than the energy form peltier due to the efficiency of heat exchanging property of the device and the heat dissipation to the surrounding. For the study the effect of the heating and cooling ability of the system to the mattress showed that the developed system had high potential to be used for heating and cooling the mattress.
