The invention relates to systems for Underfloor heating and/or cooling and can be used to create an optimal microclimate parameters in residential and office buildings and facilities.

Known technical solution (EN No. 2341627 C1, CL E04F 15/00, publ. 2008) related to heated floor, comprising mounted on the ground reinforced concrete Foundation laid on a reinforced concrete Foundation waterproofing material and sequentially stacked insulation, metal mesh, tubular heating elements arranged zigzag and attached to a metal mesh reinforced screed and floor finishes that it is provided with a layer of sand with a thickness of 25-30 mm, poured in waterproofing material, and mounted on top of the sand aerated concrete blocks, spaced with a gap relative to each other, covered with sand, the density of insulation laid on concrete blocks, is 50-200 kg/m3and a thickness of not more than 50 mm in the unloaded state, the coupler is made with a solution of coarse-grained sand with a thickness determined by the formula a≥3b, where a is the thickness of a rod, b is the diameter of the pipes of the heating elements.

The specified invention is intended only for heating floors, in addition, it does not provide the ability to control the heating system.

And�known heat exchanger design floor to control the temperature in the premises (FR 2790819 A1, CL F24D 3/16, publ. 2001), which contains a heat dissipating metal bars laid on it with a circuit for circulation of coolant and coating with a high coefficient of thermal conductivity.

Known devices of Underfloor heating (JP 2895424, F24D 3/16, publ. 2000; JP 3045135, F24D 3/16, publ. 2001) containing insulating layer with grooves for laying pipes with circulating coolant, and heat-radiating sheet material.

The disadvantage of analogs is the complexity of the control system of convective heat transfer in which there is an exchange of thermal energy between the fluid and the environment.

The closest to the claimed is a device for heating and/or cooling buildings, for example residential and official premises (RU # 2178122 C2, CL F24D 3/14, E04B 5/10, publ. 2002), containing a carrier plate on which the laid pipe, through which passes a coolant or cooling medium, arranged in heat-conducting layer, wherein the supporting plate is on the room side to maintain uniform temperature has a profile which in cross section has a sinusoidal, i.e. has projections and depressions, passing each other under a flat angle, and the pipe in the area of the depressions of the support plate is arranged in heat-conducting layer, pass with clearance from the edge and bottom of the trench.

The main disadvantage of this technical�whom the decision is thermal inertia and poor adjustability of Underfloor heating (cooling), especially in the cooling mode as heat flows from the middle of a massive layer of overlapping spread much slower than changing thermal environment due to changes in outdoor temperature and solar radiation.

The technical task of the invention is the creation of a regulated system of water Underfloor heating (cooling), the efficiency sakkumulirovannaya in the array overlap of coldness (warmth) and regulation of hoodooed (heat) to maintain the optimal parameters of microclimate in the premises.

The main difficulty in the implementation of a combination of Underfloor heating and cooling is that the heating mode has a substantially larger thermal capacity than the cooling mode, and its implementation requires 2-3 times less heat exchange surface, for heating mode the temperature difference between the coolant and the surface of the floor is 15-20°C, while the standard coolant (14/16°C) this temperature difference only 5-6°C.

The task is solved by the fact that the under-floor heating (cooling) containing insulating layer, a layer of concrete with in it fast-response heat-exchange coil for circulation of the coolant or cooling�surrounding environment, located near a floor surface, a heat-conducting metallic material, further comprises the accumulation of the heat exchange coil located in the depth of concrete layer, with low-inertia and accumulation of heat-exchange coils combined with a bypass line provided with a valve and a circulation pump, and the heat conductive material comprises a metal mesh in contact with fast-response heat-exchange coil.

The invention is illustrated more drawings and description thereto.

Fig.1 shows a cross section of the concrete slab; Fig.2 - floor heating system (cooling).

The under-floor heating (cooling) contains insulating layer 1, a layer of concrete 2, in which fast-response heat-exchange coil 3 for circulation of the coolant or cooling medium, in contact with thermally conductive material is a metal grid 4 and located near the floor surface, and accumulation of heat-exchange coil 5 is located in the deep layer of concrete, with fast-response heat-exchange coil 3 and the accumulation of heat-exchange coil 5 of the consolidated by-pass line 6, is provided with a valve 7 and the circulation pump 8, and also fast-response heat-exchange coil 3 is provided with valves 9 and the accumulator�arianny heat exchange coil 5 - valves 10. Metal grid 4 that is in contact with fast-response heat-exchange coil 3, improves the uniformity of distribution of heat across the floor surface.

The under-floor heating (cooling) works as follows.

Mode charging cold (warmth) floor construction (Fig.1) the cooling medium (coolant) is supplied in fast-response heat-exchange coil 3 (Fig.2) when you open the valves 9 and accumulation in the heat exchanger coil 5 at open gate valves 10, and the valve 7 by-pass lines 6 are closed, and the circulation pump 8 is turned off. In the mode of discharging the cold (heat) from the accumulation of heat exchanger coil 5 is transferred to a low-inertia heat exchange coil 3 by means of a circulation pump 8 at open gate valves 7-pass lines 6 and shut-off valves heat exchanger coils 9 and 10.

The connection of the accumulator 5 and low-inertia 3 heat exchanger bypass circuits lines 6 with a circulating pump 8 allows you to quickly transfer cold (warmth) from the middle of the array the design of the roof to the floor. In the daytime do not want to use a refrigeration machine to produce cold (electric boiler for heating), but enough to use in the regulated mode sakkumulirovannaya energy. Regulation of cold�impact (heat transfer) of the floor is carried out at the sensors resulting temperature installed in a room, due to the change in performance of the circulation pump. In winter there is only one coil, and in the summer - both of the coil. Comfortable temperature of the floor surface in the cold period of the year +25-26°C, warm +20-21°C. Maintaining this temperature ensures compensation of heat loss in winter and heat gain in the warm period of the year.

Significant economic advantage of combined outdoor cooling (heating) is the ability to charge coldness (warmth) in the night time concessional tariff for electricity (in most regions it is 2-4 times less than the daily rate).

The stated heating (cooling) has several advantages over traditional (radiators, convectors, fan coil units, split systems): silent; no unwanted gradients of temperature and velocity of air movement in the room; saves energy; does not occupy valuable space; allows to accumulate the cold (heat) at night. The device of Underfloor heating (cooling) with two heat exchange coils located one (fast-response heat-exchange coil) near the surface of the floor, the other (the accumulation of heat-exchange coil) in the middle of an array of overlapping, solves the problem of system management Napo�professional heating (cooling), in which there is an exchange of thermal energy between the fluid and the environment.

The under-floor heating (cooling) containing insulating layer, a layer of concrete holds heat exchanger coil for circulation of the coolant or cooling medium positioned near the floor surface, a heat-conducting metallic material, characterized in that it further comprises the accumulation of the heat exchange coil located in the depth of concrete layer, while the heat exchange coil for circulation of the coolant or cooling medium and the accumulation of heat-exchange coil combined with a bypass line provided with a valve and a circulation pump, and thermally conductive material comprises a metal grid that is in contact with a heat exchange coil for circulation of the coolant or cooling medium.
