ELECTRICAL RESISTANCE HEATING FOR AIR CONDITIONING IN DWELLINGS AND BUILDINGS

摘要

The objective of the invention is an electrical resistance heating system with an electrically conducting heating layer capable of being heated by electric current, consisting of a mixture of graphite particles and hardenable binder and capable of being operated at a minimal surface temperature. According to the invention, the mixture which forms a heating layer (11) is composed of graphite particles and a water-dilutable binder and can be applied directly to a moisture-absorbent support panel by painting, spraying, screen printing or the like in such a way that the surface load in relation to the electrical heat output of the heating layer (11) is 20 to 60 W/m<2>; the support panel in an underfloor heating system has a conventional sandwich plaster board (2), a composite board or a load-distributing layer (204) with a backing heat-insulating layer (4) and suitable for interior finishing. The field of application for the invention is air conditioning in dwellings and buildings, with a homogeneous heat radiation field which can prevent forced convection of the air in a room.
