Thermal insulator for construction using thermoelectric module

Abstract

The present invention provides a thermal insulator for construction including: a thermoelectric module inserted in a wall or floor of a building and including a plurality of thermoelectric elements; a power supply module for supplying power to the thermoelectric module; and a power control module for controlling size and polarity of the power supplied to the thermoelectric module from the power supply module. This thermal insulator for construction can provide much better thermal insulation performance in comparison with a conventional thermal insulator, and it is possible to reduce thickness of the wall or floor in comparison with when using the conventional thermal insulator since the thermoelectric element has very small size. Further, it is possible to implement a cooling or heating effect only by changing polarity and size of applied current.
