Definitions

  • the subject of the invention is an induction air-conditioning panel with increased inductance intended for ventilation, heating and air-conditioning of buildings, in particular single and multi-family residential buildings.
  • the purpose of the subject of the invention is to perform the functions of heating and cooling rooms with the minimum dimensions of the device.
  • the device uses the phenomena of air induction, Coanda effect, and the recovery of dynamic air pressure into static pressure.
  • the induction panel has water to air heat exchanger which can be supplied with hot or low water temperature (lower than dew point of air) and refrigerant both liquid and gas phase.
  • the heat exchanger can also be made in the form of an electric heater or cool and heat technology Peltier's module.
  • heat recovery pipe or heat recovery panel installed (for example, in the external partition of the room), it can form a semi-integrated and fully integrated ventilation, heating and air-conditioning device that also enable heat/cold recovery from exhaust air.
  • the version of the semi-integrated cooling and heating ventilation device is a variant that include of an induction air-conditioning panel with the increased inductance and water heat exchanger, also heat recovery pipe or heat recovery panel and an air intake-exhaust.
  • This variant requires connection to an external heat and cooling source, such as air-to-water or water-to-water heat pumps.
  • the fully integrated version of the ventilation, cooling and heating device creates a variant of an induction panel with the increased inductance, equipped with heat recovery pipe or heat recovery panel with a heat exchanger in the form of an electric heater and air intake-exhaust.
  • the fully integrated version creates a variant of the device with heat recovery pipe or heat recovery panel with two heat exchangers of the Peltier module, where one exchanger is installed in panel in the room, the other in a panel outside the room or with two heat exchanger in a closed refrigerant system also equipped with compressor and expansion valve where one exchanger is placed in room's panel and other in second panel placed outside the room.
  • the subject of the invention requires only to run electric power, which may come from photovoltaic panels or other ecological power sources.
  • the solution with a compressor requires 3, 4 times less power consumption compared to the solution with an exchanger in the form of an electric heater.
  • Heat recovery pipe and heat recovery panel are the subject of separate patent application.
  • induction air-conditioning panels mentioned in their horizontal version require the exchanger to be supplied with the cooling water at the appropriate temperature so that the condensate does not flow penetrate beyond the outline of the device. It reduces the possible cooling capacity of the device and allows for the assimilation of only sensible heat from the room.
  • the inventive solution of the induction air-conditioning panel with the increased inductance allows to reduce the distance between the diffusion panel and the heat exchanger, which in this version can be supplied with low-temperature cooling water, which increases the cooling capacity of the panel and allows for the assimilation of both sensible and latent heat gains.
  • the minimized distance between the heat exchanger in the structure according to the subject of the invention allows for the discharge of condensate even in overlapping of the heat exchanger and the diffusion panel in the longitudinal cross-section.
  • the dynamic pressure of the air flowing out of the slots or perforated holes at high speed is converted into an increase in static pressure and the pressure difference between blowing and suction side.
  • the Coanda effect is additionally used. It causes high induction of recirculated air by integrated heat exchanger even with small distance between suction and blowing side of the device. Additionally, it increases its efficiency.
  • the subject of the invention can be directly adjacent to the building partition of the room, thus reducing the space requirement for its installation in air-conditioned room. Therefore, it does not require a distance between the wall of the room and the air conditioning unit.
  • the induction air conditioning panel with increased inductance is available in two basic versions.
  • the first version with built-in supply fan unit.
  • the second version without a built-in supply fan.
  • the latter solution instead of the supply fan forcing the air to the diffusion panel, the device has an air supply and exhaust connector to which a heat recovery pipe or heat recovery panel is connected and where heat recovery is carried out along their entire length.
  • the fresh air through micro-channels of heat recovery heat recovery pipe or heat recovery panel is led to the diffusion panel of the subject of the invention.
  • the front panel/grill of the subject of the invention there are openings on its fragment through which the used air is charged to the supply-exhaust connection stub and further to the heat recovery pipe or heat recovery panel.
  • the variant without a built-in supply fan is configurable.
  • This variant differs from the unit currently available on the market in that device provides fresh air supply, exhaust used air, air induction from the room through a heat exchanger built in the device, which in its water version can be supplied with a cooling liquid of low temperature.
  • the condensate is collected for both versions of the object of the invention and with and without a supply fan in drain pan placed under the heat exchanger coils in the device case.
  • An induction air conditioning panel with increased inductance is made of housing that is also a supply and flow element, heat exchanger and fan assembly integrated with the diffusion panel.
  • the casing consists of a front panel, through which recirculating air from the room is flowing and a rear panel, mounted on the room partition.
  • the diffusion panel blows air at high speed at an angle to the front or back panel.
  • the diffusion panel which slots or perforated openings air flows out at high speed, it can be located between the front and the rear panel.
  • the diffusion panel can also be built into front panel or rear panel, then only heat exchanger is located between the front and rear panel.
  • the heat exchanger may also be built-in and integrated in the front or rear panel of the subject of the invention. Air blown from the perforated holes or through the air slots of a diffusion panel located between the front the front and rear panels or integrated in the front or rear panels is blown at high speed onto front or rear panel at an angle.
  • the front panel is equipped with openings of various shapes and cross-sections through which induced air flows from the room.
  • the diffusion panel is rear panel
  • air gaps of perforated openings protruding above the surface of the panel exude air from them at high speed, inducing room air flowing through holes placed in front panel.
  • Both front and rear panel casing panels are placed a short distance from each other, and there is a heat exchanger between them.
  • the heat exchanger can also be integrated in the front or rear panel.
  • the supply air from the rear panel can be directed towards the rear panel but also towards the front panel. In both cases induced room air flows through the flow openings in the front panel.
  • the diffusion panel is located between the front panel and rear panel of the device, it may be in close proximity to them, moreover, there may be heat exchanger coils between the blowing elements and the diffusion panel, thus reducing the overall depth of the device.
  • the heat exchanger can also be integrated in the front or rear panel.
  • the supply air in the diffusion panel can be directed at a certain angle to both the rear panel and the front panel.
  • the through-holes of the front panel are located fragmentarily on the front panel and not on its entire surface.
  • the front panel is also a diffusion panel of the device
  • perforated holes or air gaps are placed between the openings through which induced air flows into the device.
  • the slots and perforated holes are then positioned so that the air flows at high speed only to the rear panel and does not flow by the heat exchanger coils between the rear and front panel. Only induced air from the room flows through the coils.
  • condensate trays are placed under the exchanger coils. They collect the condensate formed as a result of the flow of warm air through the cold surface of the heat exchanger coil supplied with cooling water with a low temperature below the dew point of the air induced from the room and flowing into the exchanger.
  • Supply air slots or perforated openings at high speed is directed at an angle to rear panel mounted on the room wall or to the front panel.
  • the air blown on the rear panel or the front panel causes an increase in pressure in the layer of the panel, the pressure difference between the blowing and suction sides and the induction of air from the room.
  • the dynamic air pressure is recovered to increase the static pressure within the rear or front panel.
  • This air is quickly entrained due to the Coanda effect, and due to the large pressure differences between the discharge and suction sides (resulting from the conversion of the dynamic pressure of the air flowing at high speed from the slit into static pressure) the air flow from the room through the heat exchanger is intensified.
  • the Coanda effect is made possible by blowing air flowing from the slots or perforated openings to the rear or front panel at a certain angle, but also by its parallel flow along the surface of the rear or front panel.
  • the subject of the invention has been shown in an exemplary embodiment on the drawing according to the figure 1 and according to the figure 2 showing the structure and principle of operation of the device.
  • the drawing according to the figure 1 shows the solution in which the diffusion panel is placed between the front and rear panel and in the version with air blowing onto the rear panel.
  • the drawing according to the figure 2 shows an example of a solution in which the diffusion panel is both the front panel and the rear panel, and the air blast is applied to the rear panel of the subject of the invention.
  • the heat exchanger for both versions according to figure 1 and according to figure 2 is shown as being located between the front and rear panels of the housing of the subject of the invention.
  • the induction air-conditioning panel with increased inductance shown in figure 1 consists of an outer casing 1 in which, between the front 2 and rear 4 panels, there are several parallel or centrifugally star-shaped conductors, forming the so-called diffusion panel 7 and ending along the entire length with an air slot 3 or perforated holes 3. Air exiting at high speed from the air gap 3 or the perforated holes 3 is blown onto the rear baffle 4 of the case opposite the gaps/perforated holes 3. Air gaps 3 or perforate openings 3 of the housing are located at certain angle to the rear panel 4, which creates a Coanda effect in the wall layer of the partition.
  • the heat exchanger 5 can be supplied with cooling water, heating water, a refrigerant in the vapor or liquid phase.
  • the exchanger 5 may be an electric heater or Peltier module.
  • Positioning the air blast at a certain angle on the rear panel 4 for its version with parallel branches of the diffusion panel allows the positioning and displacement of the heat exchanger coil 5 even between the blower elements of the diffusion panel 7 through which air flows through slots 3 or perforated holes 3. This allows the depth dimension of the device to be reduced.
  • the heat exchanger 5 can then be supplied with cooling water, also at low temperature, and the produced condensate can also flow down by gravity on the surface of the diffusion panel 7. In this way at the same time, the correct flow of the condensate inside the object of the invention is obtained and easier to discharge them outside, together with the condensate under the heat exchanger 5.
  • the fan 6 is responsible for the air flow, which suck in the air from the room through the openings placed fragmentarily on the front panel 2 of the housing 1 and forcing it to the closed profile of the diffusion panel 7.
  • the fan 6 with the whole diffusion panel 7 and the heat exchanger 5 is placed inside the casing 1.
  • the entire structure is closed by an outer casing 1, in the front panel 2 there is are openings from the room side and through which induced air flows to the subject of the invention and which in its lower part together with the rear panel of the casing 4 forms a drip tray. from the room side through which induced air flows to the subject of the invention and which in its lower part together with the rear panel of the casing forms a condensate tray.
  • the entire structure can be located directly next to the room's building partition, allowing the induction of air from the room without keeping the distance from the wall.
  • the induction air-conditioning panel with the increased inductance from the drawing according to figure 2 is built similarly to the solution from the drawing according to figure 1 , but inside the housing 1 between the front panel 2and the rear panel 4 there is no diffusion panel 7, only the diffusion panel 7 is integrated in the front panel 2 and/or in the rear panel 4 of the enclosure 1.
  • the front panel 2 of the device also has openings through which induced air flows to the device.
  • the diffusion panel 7 can also be integrated simultaneously or exclusively with the rear panel 4 of the housing of the device 1. In the rear panel 4 then there are perforated openings 3 or air slots 3 from which air is blown at high speed onto its surface.
  • Perforated holes 3 and slots 3 extend above the surface of the rear panel 4 in such a way that air is blown over the entire surface, inducing air from the room.
  • the induced air from the room flows successively through the openings in the front panel 1, heat exchanger coils 5 and together with the air blown from the perforated openings 3 or air slots 3 it flows through the supply opening into the room.
  • Air can also be blown at high speed from the rear panel 4 to the front panel 2. Then the front panel 2 has inlet openings, located only on its fragment, through which induced air flows from the room.
