The method of construction of a wall heating panel and a wall heating panel consists in constructing an aluminium multi-channel collector, preferably with one phase transition channel, connecting it inseparably with vertical aluminium heating elements, arranging the heating elements in the grooves of a dry wall construction board, preferably magnesium, and filling the space between the grooves and the heating elements with elastic compound, and then applying paper—aluminium foil laminate onto the whole surface of the board. A wall heating panel consists of an aluminium collector (1) with stub pipes (2), inside the collector there are horizontal parallel phase transition channels (3) and a water channel (4), the phase transition channel (3) is inseparably connected with the vertical aluminium heating elements (5) which are inserted into the grooves of the dry wall construction board (6), spaces between the grooves and the heating elements are filled with elastic compound (7) and sealed with paper—aluminium foil laminate (8), whereas the top part of the collector (1) adjoins the bottom surface of the board (6).

A heating panel includes a lower panel mounted on the floor and an upper panel serving as a cover of the lower panel. The lower panel includes: a plurality of first guides protruding upward from the bottom surface to guide installation of a heating hose; and a first air passage formed as a groove on the bottom surface and the surface of the first guide, and further includes a plurality of second guides protruding upward from the bottom surface, having the first air passage on the surface thereof, and disposed between the plurality of first guides to guide installation of the heating hose. The upper panel is coupled to the lower panel and includes: a second air passage formed on the bottom surface in a groove form; and a second fastening member coupled with the first fastening member.

A single-stage carbon dioxide multi-split cooling and heating multifunctional central air conditioner, comprising a single-stage carbon dioxide circulation system using carbon dioxide as a circulation working medium; the single-stage carbon dioxide circulation system comprises an outdoor unit and a plurality of end heat exchangers provided in parallel; and the carbon dioxide medium performs cooling and/or heating in a circulating manner in a carbon dioxide compressor, an outdoor heat exchanger, a liquid storage tank and the end heat exchangers which are in communication with one another.

A universal membrane is configured to be installed between a subfloor and floor tiles to allow movement of the floor tiles relative to the subfloor. The universal membrane includes a base layer, a plurality of studs projecting from the base layer, and a plurality of sidewalls projecting from the base layer and disposed between adjacent ones of the plurality of studs. Each sidewall of the plurality of sidewalls forming a perimeter of a pocket. The base layer forms a bottom wall of the pocket.

A regulating method for a heating and/or cooling system uses at least one load circuit (6), through which a fluid as a heat transfer medium flows and switches the at least one load circuit (6) on and off in dependence on a room temperature in a room to be thermally regulated by the at least one load circuit (6). A feed temperature (T.sub.mix) of the fluid fed to the at least one load circuit (6) is set in dependence on the relative switch-on duration (D) of the at least one load circuit (6). A manifold device is also provided for a heating and/or cooling system with a control device for carrying out such a regulating method.
