ELECTRICALLY-HEATED FLOOR Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: electrically-heated floors can be constructed in dwelling and industrial buildings, animal-breeding farms, in permanently build greeneries for heating soil when growing early vegetables. Electrically-heated floor has base that is flooring slab or like, heat-insulating layer, underlining layer, heat-accumulating layer, covering, and heating elements connected in parallel. Heating elements are made in the form of carbon bands which are located between underlining layer and heat-accumulating layer. Carbon bands are of 15-100 mm width, their linear electrical resistance is 2-20 Ohm/m. Ratio of band width to band length is from 1:10 to 1:125. Ratio of total surface area of electrically-heating bands to floor area is 0.2-0.9. Application of aforesaid arrangement for construction of electrically-heated floors enhances their attractiveness for consumers. EFFECT: higher efficiency. 2 dwg
