FIG. 1
Method and arrangement for controlling a diffuser
FIELD OF THE INVENTION
The invention concerns a method in accordance with the preamble to claim 1.
The invention also concerns an arrangement in accordance with the preamble io claim 4.
S TATE OF THE ART
The diSuser is used for bringing supply air into the room space in such a way that the supply air jet can be distributed in the desired manner into the room space. An optimum range can be dimensioned for the supply air jet. whereby fee air can be distributed into the room space free of drafts. In state-of-the-art solutions, the range or throw of fee supply air jet discharging flora the diffuser can be controlled throughout, so feat with a variable flow rate system fee throw of fee supply ah· jet will remain constant at all times as will the desired distribution of the supply air jet,
DE utility patent application 202 04 970 Ul presents a supply air terminal device comprising a supply air chamber, which is formed in an elongated honsing and which contains an inlet opening and an outlet opening for fresh air, which outlet opening is formed by nozzles or by a nozzle gap. Under fee supply air chamber feere is a mixing chamber, into which fresh air is conducted from fee nozzles or nozzle gap of fee supply air chamber’s outlet opening. The fresh airflow conducted into the mixing chamber induces a circulated airflow to flow from the airconditioned room space through a heat exchanger and into fee mixing chamber. Under the mixing chamber there is the supply air terminal device’s exhaust air duct, from which a combined supply airflow formed by the fresh ait and the circulated air is conducted into the air-conditioned space. The exhaust air duct has an air guiding element, winch Is controlled in the direction of the exhaust air duct. The air guiding element comprises a shaft in a transverse direction to tire exhaust air duct and a damper as a rotary fit on the shaft. The air guiding element is used to control the direction of the supply airflow discharging from the supply air terminal device into the air-conditioned room space, so that the supply airflow is directed directly downward or directly to the side, in practice, the spreading of the diffuser’s air jet is also affected by convection, flows, which result from heat sources outside the heating and cooling system of the air-conditioned room space. Such heat sources outside tire heating and cooling system of the air-conditioned room space are formed, for example, by people in file room space and by sunlight radiating from the window into the room space. Especially one-sided heat loads in. the air-conditioned room space may him the diffuser’s supply air jet into a one-sided air jet. This will become a particular problem in situations where the ventilation system’s exhaust air terminal devices are in the opposite part of the air-conditioned room space in relation to the window wall of the air-conditioned room space. The window’s convection flow may hereby turn the diffuser’s supply air jet directly to the exhaust air terminal device. The fresh supply air will not hereby be distributed uniformly into the airconditioned room space, in consequence of which the ventilation in the airconditioned room space becomes less effective and in a cooling situation a temperature gradient will be formed between the window and the corridor zone.
SUMMARY OF THE INVENTION
The main characteristic features of the method according to the invention are presented in the characterizing part of claim 1.
The main characteristic features of the arrangement according io the invention are presented in the characterizing part of claim 4.
In the solution according to the invention, the temperature of the inside surface of the window in the air-conditioned room space is measured by a temperature sensor fitted to the inside surface of the window, and the measurement signal given by the sensor is conducted to a control unit, and the control unit is used to control an actuator controlling a control device mounted in connection with, the diffuser’s air duct, whereby based on the measured temperature the control device Is used io control an asymmetric throw pattern for the airflow discharging from the diffuser’s air duct into the air-conditioned space.
With the solution according to the invention an improvement is achieved on the above-mentioned problems, which relate to the diffuser’s fresh air distribution and which result from heat sources outside the heating and cooling system of the airconditioned room space.
In a maximum cooling situation in the summer, the window surface of the airconditioned room space is hot due to the radiation heat caused by the sun. The heat load coming from the window will hereby easily cause the supply air jet of the ceiling diffuser to turn away from the window. Turning of the ceiling diffuser’s supply air jet can be prevented by controlling a one-sided supply air jet for the ceiling diffuser, so that a larger part of the supply air jet is directed in the direction of the window and a smaller part of the supply air jet is directed elsewhere into the air-conditioned room space.
in a maximum heating situation in the winter, the window surface of the airconditioned room space is cold. A strong supply air jet directed from the ceiling diffuser towards the window could then cause- a sense of draft. The situation can be controlled by controlling a one-sided supply air jet directed from the ceiling diffuser into the air-conditioned room space, so that a smaller part of the supply air jet. is diDK 179258 B1 reeled in fte direction of the window and a larger part of the supply ah jet is d irected elsewhere into the air-conditioned room space,
In a maximum heating situation in the winter, when the room is empty and there Is need for heating in the room, a larger part of the ceiling diffusers supply air jet can be directed against the cold window surface, whereby an efficient mixing of the room air is brought about.
ht the cases mentioned above, the direction, of the ceiling diffuser’s supply air jet can be controlled based on the measurement signal of a temperature sensor mounted on the inside surface of the window.
The invention can be applied to all such diffusers intended for location in connection with the ceiling, from which the fresh airflow is discharged in the direction of the ceiling surface. The fresh airflow may discharge from the diffuser into the room space, for example, as a radial jet, as a vortex jet or as a linear jet.
Of course, the solution according to the invention can also be applied in a situation where a one-sided heat load, is caused by something else than the sun, whereby the control signal is taken from elsewhere than the window’s temperature.
The invention will be described in the following by referring to the figures in the appended drawings.

DESCRIPTION OF ADVANTAGEOUS EMBODIMENTS
Figure 1 is a cross-sectional view of a room space, in which the control principle can be seen for a diffuser located in connection with the ceiling of the airconditioned room space, hi connection with the ceiling 12 of the air-conditioned space 10 a diffuser 50 is located, from which a supply air jet LA, LB is discharged in the direction of the ceiling 12 into the air-conditioned space 10, A temperature sensor 20 is attached to the inside surface of a window 13 in the air-conditioned space for measuring the temperature of the window’s 11 inside surface. The temperature sensor 20 is connected to a control unit 30, which control unit 30 controls an actuator 40, To the actuator 40 lor its part a suitable control device is connected for controlling a throw pattern with a desired asymmetry for the fresh air jet discharging from the diffuser 50 into the air-conditioned space 10 in the direction of the ceiling 1.2,
Figure 2 is a cross-sectional vie w of a diffuser located in connection with the ceiling of an air-conditioned space and it shows an arrangement for controlling the diffuser. The diffuser here is a so-called radial diffuser 50, which comprises an air duet 51 having a circular diameter and which is directed into the air-conditioned space 10, preferably to wards the floor of the air-conditioned space 10. At the lower end of the air duct 51 there are control devices 52a, 52b, which are fanned by a round and solid bottom plate 52a and by a ceiling plate 52b, which is located at a distance from the bottom plate and which has an opening in the center. The ceiling plate 52a is connected at its opening to the bottom end of the air duct 51. Between the bottom plate 52a and the ceiling plate 52b a guiding duct 52 is thus formed in a radial direction, through which the fresh airflow LI travelling downwards in the air duct 51 is guided in a radial direction LA, LB out of the diffuser 50.
Diffuser 50 also comprises a control device 53a, 53b in air duct 51. in this embodiment, the control device 53a, 53b is formed by two horizontal, superimposed, round dampers 53a, 53b in contact with, each other. The fest or upper damper 53a rotates in the horizontal plane and fee second or lower damper 53b is supported and fixed in the air duct 51. The fest damper 53a is supported through a vertical shaft 41 to an actuator 40, which can he a driving motor. The first damper 53a supported to shaft 41 rotates rotated by driving motor 40, whereby its position in relation to tire second fixed damper 53b will change.
Each damper 53a. 53b has large openings, through which a fresh airflow LI is discharged from air duct 51 into guiding duct 52. When fee first damper 53a is rotated by driving motor 40 into a first end position, the first openings in fee first damper 53a and the second openings in the second damper 53b are placed in such a position in relation to each other, wherein on the left-hand side of motor 40 a larger free opening is formed for the fresh air LI in comparison with the free opening on the right-hand side of motor 40. The airflow LA directed to the left from the diffuser’s 50 guiding duct 52 is then larger than the airflow LB directed to the right from guiding duet 52. When the first rotating damper 53a is rotated to a second end position, which is opposite to the first end position, a contrary situation results. Hie airflow LA directed to the left in the figure is then smaller than the airflow LB directed to the right in the figure. When the first rotating damper 53a is set in a mid-position between the end positions, the airflow LA directed to the left in the figure is as large as the airflow LB directed to the right in the figure. Of course, airflow is directed radially in every direction from the diffuser’s 50 guiding duet 52, but the airflow LA directed to the left and the airflow LB directed to the right are those, which are the primary target of control. The openings in the dampers 53a, 53b are preferably such that the total surface area, of free openings letting through air is of equal size hi ail control positions of the dampers 53a, 53b, whereby the airflow’s pressure loss over dampers 53 a, 53b will remain at a constant magnitude.
Figure 3 Is a cross-sectional view of the diffuser shown in Figure 2 and it shows another arrangement for controlling the diffuser. This embodiment uses only one round damper 55, which is supported through a shaft 41 to a driving motor 40, whereby the damper 55 rotates when rotated by motor 40. In the inside surface of the lower part of air duct 51 there arc two opposite vertical control pins 54a, 54b and in the top surface of damper 55 there is a bulge 55a.
When damper 55 is rotated by driving motor 40 to a first end position, the damper’s bulge 55a will he placed at the first control pin 54a located to the left in the figure, whereby damper 55 will be inclined in a first direction in the manner shown in the figure. On the damper’s 55 left-hand side in relation to driving motor 40 a larger free opening is formed for fresh air LI in comparison with the free opening on the right-hand side in relation to driving motor 40. The airflow LA directed to the left in the figure, that is, in the tilting direction of damper 55 is then larger than the airflow LB directed to the right hi the figure. When damper 55 is rotated to the second end position opposite to the first end position, the damper’s 55 bulge 54a will be placed at the control pin 54b located at the right, whereby damper 55 will be inclined in the second opposite direction. On the right side of damper 55 a larger free opening is formed for the fresh air LI in comparison with, the free opening on the left side of damper 55. The airflow LA directed to the right in the figure, that is, in the tilting direction of damper 55, is then larger than the airflow LB directed to the left in. the figure. When damper 55 is set in the midposition. between the end positions, the airflow LA directed to the left in the figure is as large as the airflow LB directed to fee right in the figure. Damper 55 can be made more rigid with a spring, so that damper 55 is not allowed in fee midpositions to swing in fee airflow. Control pins 54a, 54b are set in such a way feat the total surface of free openings letting through air Is of equal magnitude hi ail control positions.
Figure 4 is a cross-sectional view of fee diffuser shown in Figure 2 and it show's a third arrangement for controlling a diffuser, hi this embodiment, the control device is formed by a horizontal, round damper 57, which is supported by a spacer 58 to a horizontal control bar 56 extending through an air duct 51. The control bar 51. is supported to rotate carried by the air duct’s 51 casing. Control bar 56 is connected through a horizontal shaft 41 to a driving motor 40. When control bar 56 is turned by driving motor 40, damper 57 will move with a rocking motion along with the rotary motion of shaft 56. When damper 57 is rotated by driving motor 40 into a first end position, in which damper 57 will be inclined from fee paper towards the viewer, a larger free opening Is formed for a fresh airflow LA directed from the paper towards fee viewer in comparison with the free opening for the fresh airflow LB directed towards fee paper. When damper 57 is rotated to a second, end position opposite to the first end position, a contrary situation arises. When damper 57 is set In a mid-position between fee end positions, the frosh airflow LA directed from the paper towards fee viewer is as large as tlie fresh airflow
LB directed into the paper. In this principle, the damper 57 is thus inclined hi the same manner as in the embodiment shown in Figure 3.
Figure 5 is a cross-sectional view of another diffuser located in connection with the ceiling of an air-conditioned space and it. shows a fourth arrangement for controlling a diffuser. This is a so-called air-conditioning beam 50, which comprises an elongated air duet 51 with a right-angled cross-sectional shape, which is directed into the air-conditioned space 10, preferably towards the floor of the airconditioned space 10. At that end of the air duct 51, winch opens into the airconditioned space 10, there are guiding devices 60, 61, with the aid of which the airflow L1+L2 arriving from air duct 51 is guided in the direction of the ceiling of the air-conditioned space LA. LB out of the diffuser 50. The guiding devices 60. 61 are formed by a control piece 60, which has a triangular cross-section and which extends in. the lengthwise direction over the entire length of air duet 51, and by a guiding plate 61, which is located in a direction transverse to the air duct 51 and on top of which die base of the triangular control piece 60 is resting. Diffuser 50 also comprises a control device 60 in the ah' duct 51.
Above the air duct 51 there is an elongated fresh air chamber 51a, which has a rectangular cross-section and hi the bottom wall of which there is a nozzle row 51b and in the back wall of which there is an inlet opening 51c, from which fresh air is blown into die fresh, air chamber 51a. The fresh air is guided from fresh atr chamber 51a through the row of nozzles 51b into air duet 51. The side walls of air duct 51 are formed by heat exchangers 70a, 70b, which have a rectangular crosssection, The fresh airflow LI blown into air duct 51 induces a circulated airflow L2 to flow from the air-conditioned space through die heat exchangers 70a, 70b into air duct 51, in which the fresh airflow LI and the circulated airflow L2 are mixed together to form a combined airflow L1+L2, which is guided in the direction of the ceiling to die left LA and to the right LB into die air-conditioned space. Thus, the air duct 51 also fimctions as a mixing chamber. In the heat exchangers .10
70a, 70b the circulated airflow L2 can be either heated or cooled. A nozzle gap may be used instead of the fresh air chamber’s 51a nozzle row 51b.
In this embodiment, the control device 60 is formed by the above-mentioned triangular control piece 60. The base of the triangular control pi ece 60 is resting on the air duct’s 51 transverse guiding plate 61. The control piece 60 is connected to an actuator 40. whereby control piece 60 can be moved along the top surface of guiding plate 61 in tire transverse direction St of air duct 51. When control piece 60 is in the middle of air duet 51, as shown in the figure, the combined airflow Ll -i-L2 discharging from air duct 51 into the air-conditioned space will be divided equally to the left LA and to the right LB. When control piece 60 is moved to the right in the figure, a larger part of the combined airflow LI+L2 discharging from air duct 51 into tire air-conditioned room space will be directed to the left LA than to the right LB. When control piece 60 is moved to the left in the figure, the situation is reversed, that is, a larger part of the combined airflow L1+L2 discharging from air duet 51 into the air-conditioned room space is directed to the right LB than to the left LA. The actuator 40 may be formed, for example, by a driving motor and by a toothed gear connected to it through a shaft (not shown hi the figure), The driving motor’s toothed gear can for its part be connected to a toothed bar mounted to the bottom surface of control piece 60, The driving motor rotates the toothed gear, which for its pari moves the toothed bar and in this way the control piece 60 in a direction SI transverse to air duct 51.
Figure 6 is a cross-sectional view of a third diffuser located in connection with the ceiling of an air-conditioned space, in which the arrangement for controlling a diffuser shown in Figure 5 is also applied. This is a so-called gap diffuser 50, which comprises au elongated, air duct 51, which has a right-angled cross-section and which is directed Into the air-conditioned space 10, preferably towards the floor of the air-conditioned space 10. The guiding devices 60, 61 and the control device 60 located at the bottom end of air duct 51 correspond entirely with the solution shown in Figure 5. The side walls of air duet 51 are here formed by plates
71a, 71b, in the bottom ends of winch there are bends guiding the airflow LI to the sides.
Above air duet 51 there is an elongated, rectangular fresh air flow 51a, the bottom of which is entirely open or covered by a sparse grate and in the side wall of which there is an inlet opening 51c, from which fresh air is blown into the fresh air chamber 51a. The fresh air LI is guided through the bottom of the fresh air chamber 51 a into air duct 5.1.
The control unit 30 shown in Figure 1 may be formed by a separate control unit 30, but control unit 30 may also he integrated in the control electronics of driving motor 40.
Only some advantageous embodiments of die invention were presented above, and it is obvious to a person skilled in the art that numerous modifications can be made to these within the scope of the appended claims.
