The invention relates to the field of heating technology and systems for cooling and can be used to maintain the temperature in the residential and industrial buildings both in winter and in summer.

The known method of maintaining the temperature in the residential and industrial buildings and device high-pressure ducted air conditioning with heating function for its implementation. The device consists of an outdoor unit inverter cooling system, producing heat or cold, and internal inverter unit of the refrigeration system with internal heat exchanger, cooled high-pressure fan.

In the internal heat exchanger of the indoor unit comes with a hot or cold working fluid from an external unit. The air from the room using a high pressure fan is sucked into the indoor unit of the device, passes through the internal heat exchanger, which is heated or cooled, and distributed pipeline flows back into the room.

The disadvantage of this device are significant flows of the heated or cooled air circulating in the room when his work is affecting the indoor climate, as well as the fact that when the device is in the cooling on the inner surfaces of the heat exchanger results in condensation of moisture, contained in the atmosphere of the room. This circumstance leads to the growth of non-productive energy consumption for cooling and negatively affects the humidity of the air in the room.

The disadvantages of this method is also a low proportion of the radiant component of heat or cooling of the people inside the premises. ("Heating, ventilation and air conditioning (theoretical basics of creating a microclimate in the room). - Polushkin VI and other SPb: Profession, 2002.).

The aim of the invention is the reduction or elimination of forced air circulation throughout the room and preventing condensation of moisture from the air on the cooled surfaces, as well as increasing the share of the radiant component of heating or cooling.

This objective is achieved in that the heat or cold from the circulating air is passed into the volume of space indirectly by heat transfer through the outer surface of the heating/cooling panels, inside of which circulates a heating/cooling air.

Preferably the circulating air is humidified by means of one or more fogging devices.

When the device is in heating mode return air preferably humidified by the appliance.

Preferably within the device support the side of the vacuum.

Heating/cooling panels are preferably installed along the ceiling, walls or floor of the room closely or at a small distance from them.

Preferably provide forced air cooling side heating/cooling panel, facing the ceiling, walls or floor, with the withdrawal of heated/cooled air into the room through the openings along the edges of the panels.

Heating/cooling panel preferably consists of two flat or corrugated, hermetically joined to each other along the edges of the surfaces between which are partitions that prevent closure surfaces to each other under the action of atmospheric pressure, and separating the internal volume of the hollow panels on the cell, which moves the circulating air.

Preferably the cross-section of the internal cells of a heating/cooling panels smoothly or stepwise decreases according to the direction of circulating air.

Preferably the heat transfer characteristics of the surface heating/cooling panels smoothly or stepwise increases according to the movement direction of the circulating air.

The ducts, the inlet of the circulating air from the indoor unit to the heating/cooling panels and discharge it back, preferably in the ideal two flat, hermetically joined to each other along the edges of the surfaces between which are partitions that prevent closure surfaces to each other under the action of atmospheric pressure, and separating the internal volume of the ducts hollow longitudinal cells, which moves the circulating air.

Openings connecting the longitudinal cells of the ducts and longitudinal cell heating/cooling panels, preferably lie along the diagonal of the site of the crossing panel duct.

Panel and ducts are preferably set at some distance from each other.

The use of the claimed invention allows to obtain the following technical result.

The method will allow transmission of heat or cold from the inverter cooling system the air through the heating/cooling panels installed on the ceiling, on the floor or along the walls of the room.

The use of heating/cooling panels will increase the proportion of radiant component for heating/cooling of the people inside the premises.

The method will reduce or eliminate air circulation inside the room.

The way to avoid lowering the relative humidity of the air inside the premises when the operation mode is cooling.

Hydration of the circulating air by means of romanobritish or steam generator will increase the relative heat content of the circulating air. The increase in the heat content of the circulating humidified air will while maintaining the required cold or thermal performance of the device or reduce the volumetric rate of the circulating air flow, or reduce the temperature difference between air entering and leaving the heating/cooling panels.

Lowering the pressure inside the device, with a corresponding decrease in the density of the circulating air will significantly increase the apparent speed while maintaining or reducing energy costs on the blower device.

Low air pressure will increase the speed of achieving thermodynamic equilibrium in the processes of evaporation and condensation of a liquid circulating system together with the air flow.

High-speed transfer of the circulating air flow through the narrow channels of the panels and ducts will allow you to move the condensed liquid droplets together with the air flow, including against the action of gravity.

Use as a working fluid hydroalcoholic solution will increase the relative enthalpy of the circus which regulates air.

The increase in air flow rate, moving on to the final stretch of the canal, heating/cooling panel, compared with the initial plot, will increase the heat transfer coefficient between the moving air and the wall of the channel and substantially equalize the heat flow transmitted to the walls of the start and end parts of the channel from the cooling/heating along the channel of the air.

Enhancement of heat transfer characteristics of the walls of the heating/cooling panels according to the direction of movement of the circulating air will substantially equalize the heat exchanger flows to the indoor air or teploizolyatsii flows walls of the premises, running from the start and end zones of heating/cooling panels.

The use of air with low aerosol and droplet liquid as the heat transfer fluid closed loop heat transfer system will significantly reduce the contribution of the mass of the heat carrier in the total weight of the heating/cooling panels in comparison with traditional systems circulating liquid heating/cooling with the same space heat/teplovosprinimajushchie surfaces.

Considerable heat/teplovosprinimajushchie surface heating/cooling panels placed on the floor or on the ceiling placed the I, will achieve significant capacity heating/cooling at a low temperature heating/cooling panels and respectively at a small temperature difference between the circulating working fluid and air. Also, will significantly increase the contribution of the radiant component for heating/cooling of the room and occupants.

The small temperature difference will increase the efficiency of heating/cooling and to achieve high performance indoor climate.

The invention is illustrated in the drawing, where figure 1 shows the design of the device to maintain the temperature in residential and industrial premises, with panels placed along the ceiling of the room, side view; figure 2 is the same, end view. Figure 3 shows the circulation flow of outdoor air, transferring the heat/cold in the volume of space from the top side panels. Figure 4 shows a diagram of the internal air flow circulating in the device top view. Figure 5 shows a magnified cross section of a heating/cooling panel in the initial zone of the moving air stream, figure 6 is the same, in the end zone.

The device consists of the indoor unit 1 inverter cooling system comprising a heat exchanger 2, the internal height is Conpany fan 3, fogging devices 4, 5, immersed in the working fluid 13 and the external fan 6, the ducts 7 and the heating/cooling panels 8, containing the channels 9 and 10 are connected to each other by means of openings 11, the panels coated with the lower side teplosberezheniya film 12.

The device operation is carried out as follows.

Circulating in the internal cavities of the device, air is drawn into the indoor unit 1, passes through the heat exchanger 2, which is heated or cooled, and high-pressure fan 3 is fed into the duct 7, 9 cells reaches the openings 11, through which enters the cell 10 panels 8. Next the air passes through the cells 10 of the panels 8, which are respectively cooled or heated, and then through the openings 11 enters the cells 9 of the duct 7, which is returned in block 1, closing the loop.

The walls of the openings 11, which connects the panel 8 and the ducts 7, have a certain height to provide clearance between the duct and panels. The gap allows air exchange between the cavities located on opposite sides of the panel.

When the device is in heating mode ultrasonic fogging device 4, is immersed in the liquid 13, forms an aerosol mixture, which wets the surfaces of the heat exchanger 2 and moisturizes the festival is ASI through him recirculating air. When heated circulating air part of the liquid evaporates, absorbing a significant amount of heat. The vapor content of the heated air increases. When the air reaches the heat-release channels of the panels, in which it is cooled, airborne water vapor is partially condensed, giving heat of condensation of the wall panels. Heat the walls of the panels is also passed by the partial cooling passing through its channels of air. The condensed liquid is fond of high speed air flow, and with it returns to the block 1 to a misting device 4.

When the device is in cooling mode ultrasonic fogging device 5, is immersed in the liquid 13, forms an aerosol mixture which reaches the channels 10 of the cooling panels 8. Aerosol mixture, during its movement wets the inner surface of the channels 10 panels. Upon contact with the heated surfaces of the panels wetting their liquid evaporates, absorbing a significant amount of heat and increasing the vapor content of the heated air. When heated circulating air through anhydride wall panels, the liquid contained in the droplets of the aerosol, also evaporates, absorbing a significant amount of heat. The heated air with high steam quality and comes in nl is 1. Passing through the cooling heat exchanger 2, the air is cooled to the condensation of the contained vapor of the liquid. The condensed liquid flows into the lower part of unit 1 and returns to the fogging device 5.

As the working fluid used distilled water. To provide a higher steam content of the circulating air is used boiling liquid, for example environmentally and fire-safe water-alcohol solution.

Preferably considered in the system maintain the vacuum. This decreases the proportion of heat transferred by the heat of non-condensable gases, however, increases the proportion of heat transferred in pairs condensable fluid. The increase of this share is as due to the increase of the relative humidity of the circulating gas mixture due to the increased evaporation rate of the liquid in rarefied gas environments, and by increasing the volumetric velocity of the sparse air flow due to decrease their viscosity. The vacuum can be maintained by using a compressor or a vacuum pump, is installed, for example, in the outdoor unit inverter cooling system. This compressor can also provide work ejector fogging device. In this case carried by the PR air out of the system and its reverse flow in the ejector device. Ejector device can also be used to move portions of liquid from one system to another, including against gravity.

When space heating device can operate in the following mode. The liquid 13 from the indoor unit 1 serves in an external steam generator, gas-fired or electric heaters. Obtained in the steam generator steam returns to the circulating air.

The heat exchange between the heating/cooling panels 8 and the air is as follows.

From the bottom of the panels, heat exchange is carried out directly by direct heat transfer and thermal radiation. For heat exchange with the upper surface of the panels is provided with an external fan 6 indoor unit 1, which feeds the air from the room into the gap between the ceiling and the heating/cooling panels (see figure 3). The air passes along the upper surface of the panels is heated or cooled depending on the mode of the device, and through the openings in the panels or through the openings between panels and walls comes into the room. Thus the top area of the walls is also heated or cooled, providing the increase of the contribution of radiant heating and cooling.

One way to increase the capacity of the system heating/cooling is HC is the chances of improving the temperature difference between the incoming panel and leaving them a coolant (air). However, this method is in conflict with the hygiene requirements, requiring that the temperature difference between the initial sections of the heat exchange panel and end sections does not exceed a certain value. To reduce the temperature difference between the data areas while maintaining the high temperature difference between the incoming and outgoing coolant applied the following configuration panels: the upper side of the cells gradually deepens in the center from the initial zone of the cell to the destination (see figure 5, 6). In the area of the openings 11, which connects the cell 10 panels with cells of the ducts 9, the upper side of the cell to ensure the tightness of the openings of the flat.

The mechanism of action consider the example of a device operating in cooling mode.

In the beginning of the movement of the fluid (air), when the temperature minimum, the cross section of the cells of the panel the most. As the fluid in the cell, its temperature increases, however, decreases the cross-section of the cells of the panels, so that the velocity of the air increases, more turbulence, resulting in a higher rate of heat transfer from the walls of the panel. By increasing the coefficient of heat transfer efficiency of heat transfer from the wall panel to the coolant increases, which partially is about compensates for the power loss of heat transfer due to the temperature increase of the coolant.

The difference in power is transferred to the cold outside air from different cooled from the inside walls partially offset by a change in surface area of heat transfer and change in the coefficient of thermal conductivity of the heat transfer walls of the respective sections of the panels.

The relative power and heat from outdoor air to less cold walls of the upper surface of the end part of the panel is higher than the relative power of the heat transfer from the outside air to the cooler walls of the upper surface of the initial part of the panel due to the larger area of heat transfer (the greater the total surface of the panel).

To apply the developed surface to the bottom side of the panel is difficult for aesthetic reasons. Traditionally ceilings have a flat bottom surface. To align the operating temperature to prevent condensation of atmospheric moisture on the cold parts of the underside of the panels are provided with teplosberezheniya film 12 with different on different parts of the heat-conducting characteristics. Heat transfer characteristics of film on cooler initial part of the panel is higher than the heat transfer characteristics of the film to less cold end part of the panel that leads to equalization of the temperatures on the outer surface of the film.

To prevent to is densely atmospheric moisture from the outside air, relative humidity which during the day is constantly changing, for panel systems typically involve multi-layered defense system and maintain the temperature of the coldest areas on the panels a few degrees above the dew point, which significantly affects the cold performance panel cooling systems. In this device the coldest outer area of the cooling pad is the top surface of the initial part of the panel. If you install a humidity sensor that is triggered when a minor overcooling the zone below the dew point, the automation of this device will greatly simplified while maintaining extreme cooling mode. Condensed in this area the moisture flowing under the action of gravity along the grooves in the less cold end panel area where the moisture evaporates again in the atmosphere of the room.

FIELD: heat-and-power engineering.

SUBSTANCE: method of heat supply which is based upon sequent transporting of two chemical reaction hidden heat matters-carriers to consumer, heat extraction for consuming by means of direct exoergic chemical reaction of transformation of those matters to single matter-product of direct reaction, transportation of the matter to primary heat energy primary source and its reverse transformation to two initial matters by means of reverse endoergic reaction to accumulate primary heat source heat chemical form. As matters-carriers of hidden heat of chemical reaction gaseous or liquid chemisorbent - carbon dioxide and solution of at least one chemisorbent in water or in organic solvent, for example, monoethanoamine that has content of chemisorbent lower than 60%. Physical heat whish is rest after transmission which heat achieved as result of direct reaction of chemical adsorption product is partially or totally recuperated due to performing heat exchange between the matter and chemosorbent and chemosorbent solution which center for direct reaction. Physical heat of chemosorbent and chemosorbent solution restored during reverse reaction is partially or totally recuperated due to carrying heat exchange out between them and product of chemical adsorption entering for reverse reaction.

EFFECT: savings of heat energy; reduced amount of heat of primary source.
