The heating method
The invention relates to a heating engineer and can be used for heating of industrial, agricultural and public buildings. The method is carried out by mixing in the jet of hot air from the heat with a cold from the premises, and the suction of cold air exercise with the lower point of the room by the ejector through which extends the mixed air with a given constant temperature. The technical result of the invention is to eliminate the temperature gradient along the height of the room, saving heat and electricity. 1 Il. The invention relates to a heating engineer and can be used for heating of industrial, agricultural and public buildings.The closest technical solution adopted for the prototype, is the method of heating large areas where cold air collects in the collector, made in the floor, and from there is fed to the heat source, then through distributing nozzle and eductor mixers installed in the upper area of the premises, which is implemented in the heating system of the premises.The disadvantages of this method, proracer air from the heat with a cold from the premises, as well as excessive energy consumption of the installation and the additional financial cost of the installation of the headers.Object of the present invention is to eliminate the temperature gradient along the height of the room, saving heat and electricity.The task is implemented through mezhrajjonnogo distribution of thermal energy in the height of the premises, carried out by mixing in a jet of hot air from the heat with a cold from the premises by the ejector through which extends the mixed air with a given constant temperature.A distinctive feature of the proposed method of space heating from above, closest to him, is that leak cold air exercise with the lower point of the room by the ejector, which uses part of the velocity head of the fan heater.The coefficient of ejection of the ejector is selected by the calculation method so that the temperature of the mixture ejected and the ejection of the air flow was in accordance with the requirements of the TDA or sanitary standards for this type of premises.The ejector can be installed in any part of the premises, for example, as shown in certeine and therefore, the solution is new and involves an inventive step.The implementation of the method is illustrated by the drawing device.Device heating provides heat generator 1, a distributing pipe duct 2, the ejector 3.The method of heating is carried out as follows.Intake air is preheated in the heat generator 1, passes through the duct to the distributing pipe 2 and then enters the ejector 3. Thus ejected cooler air sucked by the ejector from the bottom point of the room (this is the part of the velocity head of the fan of the heat source and through the confuser enters the mixing chamber, where it mixes with hot, achieved a high degree of alignment of the velocity fields air mixture flow and air temperature. Then the mixed flow of air through the diffuser comes out, reducing the speed and expands, increases the contact area with the ambient air, where there is a further averaging of thermal energy. Resulting in a uniform temperature field along the height of the premises to a specified temperature and are provided with comfortable working conditions in the working area.Heating of the air in Teploenergo Ecevit - heat energy savings without additional energy consumption due to the optimum distribution along the height of the room during the heating supply heating installations; - the elimination of the temperature gradient along the height of the room and create a comfortable environment in the working area; - eliminates overheating of the floor space and abnormal icing in winter conditions on the cornice of the ceiling.
ClaimsThe method of heating high spaces, including the forced mixing of the hot air from the heat and cold air from the premises, characterized in that the suction of cold air exercise with the lower point of the room by the ejector.
FIELD: building construction.
SUBSTANCE: building has foundation with grillage, support member placed onto grillage, metal frame composed of posts with connecting items, which posts are fastened to support member, and reference beams connected with posts, slabs, walls formed by internal and wall panels mounted to have space in between, heating system. Posts, connecting items, and support beams of metal frame are made in form of boxes. Panels of slabs are made hollow. Building has air-forced heating system; it is provided with heat exchanger and is provided with heat exchanger to for air duct inside posts, connecting members and support beams of metal frame, cavities of panel slabs and space between external and internal wall panel to let heated air medium circulate, which medium warms room through warmed walls and ceiling. Slabs are made of metal curved U-shaped profile, disposed with its shelves outside at two sides along side surface of panel to fix profile on shelves at any side of facing sheet provided with sound-isolating layer, or with heat-insulating layer for panel of ground floor, which on one side has to be basis for floor structure and on the side - floor slab, mounted at internal side onto heat-insulating layer. Units for fixing panel to metal frame are made in form of metal U-shaped insertions, placed and fixed along perimeter of panel in heat-insulating layer and fastened with external decorative layer; there are also metal plates attached to the panels. Internal wall panels have facing layer, sound-insulating layer and members for fixing panel to metal frame, which members are made in form of U-shaped cross-section insertion disposed along perimeter of panel in sound-insulating layer and fixed onto insertions of metal plates. Mounting costs of for pipelines for heating systems can be reduced or rejected due to usage of members of carrier structure of building as pipelines.
EFFECT: reduced labor input; rejection of costs on mounting of pipeline of heating system.
