Due to the special properties of the thermoelectrical effect, Peltier devices can be used for both heating and cooling. 由于其特有的热电效应，珀尔贴装置在加热和冷却条件下都可以使用。
Spurious microvolt level signals are often present in low resistance circuits, most often as a result of thermoelectric effects. 在低阻电路上往往会出现毫伏级的杂散信号，大多数是由于热电效应引起的。
