  1. Evaluation of the Performances of Electrically Heated Clothing

    … these problems, a slim garment with a built-in heating element could be useful. The heat input power and heating efficiency are the two most important parameters for a piece of heated clothing. The input power determines how much heat can be released from the whole clothing system, while the …
