Door with integrated heating surfaces

摘要

The door has a door panel (1) and a cooperating door frame (2), with one or more of the door panel surfaces (3,4) and/or the door frame provided with incorporated heat transfer surfaces supplied with a heat transfer medium e.g. hot or cold water. The closed and open sides of the door and the door frame are thermically and hydraulically separated from one another, with independent circulation of the heat transfer medium. The door may incorporate electrical power and signal lines, e.g. for operation of electrical sensors and/or a door operating drive.
