Known greenhouse, containing vegetation units, including mounted on a triangular frames and on the basis of the greenhouse trays for growing plants, communicated with the system of preparation of the nutrient solution, irradiation, VK is between neighboring vegetation blocks, and the second group of sources of optical radiation, located in the cavities between the triangular frames each vegetation unit and the base of the greenhouse, the heating system comprising a source of water heating and two heating sections of the heating elements the first of which is made in the form of ducts, which parts are positioned below the triangular frames that have two curved surfaces facing its concave part in the direction established under them sources of optical radiation of the second group, and the control unit with power supply.

A disadvantage of the known greenhouse is uneven heating in the amount of greenhouses, including space cenosis, which leads to low quality and productivity of farmed products.

The task of the invention is the creation of a greenhouse, which provides uniform heating of greenhouses that will affect the growing season and crop yield.

The claimed invention solved the problem of ensuring the uniformity of heating of the space in and around the vegetation units in the greenhouse, and therefore, in the area of cenosis that stimulates plant growth and affect the growing season and increase yields.

on bottom tray for growing plants, installed on triangular frames and trays for growing plants, on the basis of the greenhouse, and the control unit is equipped with a communication nodes, each of which contains one switch and two guard key element, the first terminal of one of the guard key elements of each switching node connected to the first output of the corresponding source of optical radiation of the first or second group, and a second terminal connected to the first terminal of the second closing key element and a switching contact switching key element of the switching node, the second terminal of the second closing key element connected with the first output of the corresponding heating element, the second output of which is connected to one polar terminal of the power source and to the first switching terminal of the switching key element of the above-mentioned switching node and the second switching terminal of this switching key element connected with the second output of the corresponding source of optical radiation of the first or second group, and with other polar terminal of the power supply, with at least coming to the sources of choice for the

In a preferred embodiment of the greenhouse heating system is equipped with a third heating section including a heat transfer paths connected to a source of water heating and posted on the surfaces of the ducts are covered with a reflective layer.

The invention achieves the following technical result.

The presence of a greenhouse heating system comprising three heating sections of the heating elements one of which is located under the bottom of the trays installed on triangular frames, trays and placed on the basis of the greenhouse inside a triangular frame, running off radiation sources, for example, at night will improve the temperature regime in the area cenosis of plants, and consequently, to increase the yield.

Equipment other sections of the heater, made in the form of ducts placed inside a triangular frame and having two curved surfaces facing its concave part aside installed underneath radiation sources, and the third heating section including a heat transfer paths connected to a source of water heating and posted on the surfaces of the ducts are covered with a reflective layer, called the greenhouse and therefore increase the yield of crops.

Connect ducts to water heating system will allow you to use the warmth of the light sources for heating greenhouses, to reduce overheating of the lamps, therefore, to save heat energy.

The management systems of irradiation and heating of the greenhouse with the control unit equipped with the switching nodes, will allow the systems to provide uniform heating of the space in the greenhouse and to increase productivity.

The invention can be used in agriculture, which allows to improve the temperature regime, to ensure uniformity of heating plants, to reduce the consumption of thermal energy and to increase yields by 7 to 11%

In Fig.1 shows the greenhouse, end view; Fig.2 hydroponic setup with vegetation blocks; Fig.3 the circuit diagram of the control operation of the heating and irradiation, and Fig.4 parts of a heating system.

The greenhouse contains a translucent barrier 1, hydroponic installation 2 containing vegetation units 3, including mounted on a triangular frames 4 tray 5 for growing plants 6 provided with the system of preparation of the nutrient solution (not shown), the irradiation system including a first group of sources 7 otrajaya located in the cavities between the triangular frames 4 of each vegetation unit 3 and the base 9 of the greenhouse.

The heating system includes a source of water heating 33 (Fig.4) and two heating sections. The heating elements 10 of the first heating section is made in the form of a duct having two curved surfaces 11,12, facing its concave part aside installed underneath radiation sources 8.

The heating elements 13 of the second heating section is located under the bottom of the trays 5, installed on a triangular frames 4, and tray 5 is placed on the base 9 of the greenhouse. The control unit is supplied by the switching nodes, each of which contains one switch 14 and the two ends 15, 16 of the key element (Fig.3). The first terminal 17 closing the key element 15 of each switching node through gear apparatus connected to the first output 18 of the radiation source 7 or 8 the first or second group (Fig.3 shows the connection of the lamp 8), the second terminal 19 is connected with the first terminal 20 of the second closing key element 16 and the switching contact 21 switching key element 14 of the switching node.

The second terminal 22 of the second closing key element 16 is connected with the first output 23 of the heating element 13, the second terminal 24 which is connected to one of the polar crionna terminal 28 switching key element 14 is connected to the second output 29 of the optical radiation source 8 (or 7) and with the polar terminal of power supply 26. In the control unit all the switching nodes connected to the panel 30. Closest to the radiation source 8 curved surface 12 of the duct 10 is covered with a reflective layer 31.

The heating system is equipped with a third heating section, including the contours of the heat exchanger 32, is connected to the source of water heating 33 and placed on the surface 11 of the duct 10, is covered with a reflective layer 31 (Fig.4).

In the drawing position 34 shows the external piping (outside hydroponic setup), position 35, the input source of carbon dioxide.

System irradiation and heating may contain one radiation source 7,8 and one heating element 13, and several parallel-connected sources of radiation and heating elements.

A greenhouse works as follows. Heating system and provide the necessary exposure for plant development 6 radiation and thermal conditions in the greenhouse. In day time the radiation sources 7,8 provide exposure cenosis plants 6 as the outside and inside.

The heat generated by the light radiation 7, heats the cenosis outside the vegetation units 3. Warm light radiation 8 is heated will wasoccupied moist air, carbon dioxide CO2. In addition, the heated air transfers heat to the water heating system of the greenhouse.

At night, the control box 30 according to the set program switches the power light radiation 7,8 or only 8 on the heating elements 13 positioned below the bottom of the trays 5, located on a triangular frames 4 and the base 9 of the greenhouse. Heating cenosis with heating elements 10 and 11 aligns the temperature gradient along the height (inclined cenosis) and in the center of the cenosis (horizontal cenosis).

The mode of irradiation and heating cenosis depending on the temperature in the greenhouse and value of the incoming natural (solar) radiation regulate disable and enable parallel connected lamps irradiation 8 and the heating elements 10.

The use of a greenhouse hydroponic system to grow plants in which the heating elements are located under the bottom of the trays installed on triangular frames and on the basis of the greenhouse will provide uniform heating plants in the greenhouse, to increase yields by 7 to 11% and to reduce the consumption of thermal energy.
