The latest generation of heated and cooled seats in vehicles operate using Peltier devices that convert electricity into temperature differentials without resorting to compressors or liquid coolants. Temperature control is by means of a Peltier device which is said to offer simplicity and compactness, as well as relatively rapid changes in set point temperature. A reversing DC test current eliminates errors caused by device heating associated with conventional DC resistance measurements on Peltier devices. |
