TEMPERATURE CONTROL METHOD OF A COOLING/HEATING DEVICE USING A THERMOELECTRIC ELEMENT MODULE, CAPABLE OF ENHANCING THE PERFORMANCE OR THE EFFICIENCY OF A COOLING/HEATING DEVICE

摘要

PURPOSE: A temperature control method of a cooling/heating device using a thermoelectric element module is provided to minimize the performance decrease caused by the change of external environment by determining the operating voltage of a thermoelectric element module based on the external temperature and the internal temperature of a cooling/heating device.;CONSTITUTION: The temperature of a cooling/heating part(10) and the temperature (T2) of a waste heat emitting part(20) are measured respectively. The mode value predetermined by a controller(40) is detected. The temperature of the cooling/heating part is compared with first and second predetermined temperatures. If the temperature of the cooling/heating part is higher than the first predetermined temperature or lower than the second predetermined temperature, the cooling/heating part is selectively controlled in a maximum efficiency mode, a maximum performance mode and an optimal operating mode by calculating the temperature difference between the heat radiating and the heat absorbing of a thermoelectric element module(30) based on the temperatures of the cooling/heating part and the waste heat emitting part.;COPYRIGHT KIPO 2011
