Description

Natural Convection Air Conditioning System

According to the present invention, since the air inlet is installed at a predetermined interval on the opposite side of the discharge port to generate a wind close to the natural wind, air pressure difference is generated in the room. It relates to a natural convection cold and hot air system.

In general, natural wind blows irregularly because it is caused by the pressure difference between two regions.

The artificial wind generated by rotating the blades in an electric fan, an air conditioner, or the like is intermittently blown by being caused by forcibly cutting off the air. In other words, natural wind does not generate pressure waves, but artificial wind generated by the rotating body generates pressure waves that are in a dense state and are mechanically and regularly transmitted.

In the above, the dense state refers to a state in which a small state in which the air molecules are coarse (a portion of small air density) and a dense state in which the air molecules are dense (a portion of high air density) are repeatedly followed.

In the above, the pressure wave refers to the movement of the artificial wind generated by rotating the rotating body in a fan or a cold / hot fan by forcibly cutting off the air. When the wind is intermittently generated, the pressure difference due to the minute roughness of the wind and the mechanical Continuity and regularity have a form of continuous and regular periods of some form, a description of the pressure difference and its mechanical regular period.

As described above, when the human body is exposed to an artificial wind for generating a pressure wave for a long time, headache or skin tingling or pain is felt, and a swelling of the face occurs. This is a phenomenon that occurs as the compactness of the artificial wind and mechanically repeated pressure waves continuously strike (slap) the skin at a certain frequency.

In the prior art, since the wind blows unilaterally from the rotating body or the hot and cold fan side to the room, the wind cannot reach far away due to the resistance of the indoor air or the strength of the wind rapidly weakens, so that the entire convection can be quickly and smoothly. There is a problem that is not made.

In other words, natural wind flows from one side to the other continuously by two forces that naturally push or pull air due to the air pressure difference between the high pressure and the low pressure, whereas the conventional method of the injection method by the pressure difference is the wind from one side. Because only forced air is blown, natural convection does not occur due to the pressure of indoor air and the resistance generated by air particles. For reference, the weight of air 1㎥ at temperature of 0 ℃ and pressure of 1㎏ / ㎠ is 1.251㎏, so the wind has to overcome the resistance by the weight of the air, so the strength decreases gradually as it moves away from the outlet and the overall convection It does not occur.

In particular, in the case of the cold and hot air fan, the discharge port is located on the upper side and the suction port is located on the lower side of the vertical line, so the convection circulation range is very short, and the wind does not tend to be transmitted far.

However, the natural wind hits the skin with an irregular wind, which is unpredictable by two forces that push or pull due to the irregular air pressure difference, which is significantly less than the artificial wind, and thus the skin is exposed to the natural wind for a long time. Even if you do not feel the tingling or swelling does not occur, you will have a soft feeling.

According to the present invention, the suction port is installed at a position far from the discharge port, so that the indoor air is sucked, so that it communicates with the case with a duct or a hose to make a low pressure state from the discharge port, and the user is located between the discharge port and the suction port. As the movement of air is made by air pressure by air pressure difference like natural wind, the movement of cold and hot air is not unreasonable. Therefore, the distribution of indoor temperature is good and the temperature control is easy. It is formed quickly and smoothly to increase user's comfort, and it can save energy by shortening the time of cooling and heating and managing the effective and direct cold and hot wind.

The object of the present invention is to discharge the air sucked from the suction port at a predetermined angle to the wind discharged toward the discharge port to impinge on each other by disturbing the pressure waves and by installing the suction port at a position far from the discharge port to give a pressure difference in the room It is to provide a natural convection cold and hot air system in which indoor airflow naturally convections by two forces that push or pull like a natural wind.

In addition, the present invention efficiently supplies the wind close to the natural wind to make the convection as a whole naturally, and by controlling the collision (mixing) ratio of the air discharged from the blower and passed through the heat exchanger and the indoor air sucked through the suction port The user can easily control the temperature of the discharge wind and directly supply the wind (cold or hot air) to the area where the person is located to provide a natural convection cold and hot wind system that can increase energy efficiency and achieve energy saving.

The suction port 50 is preferably provided with a filter 58 for filtering foreign matter from the air sucked in.

The suction blade 54 may be implemented by applying a variety of methods, such as a propeller method, an impeller method, a sirocco fan method.

In addition, the suction motor 53 may not be installed in the suction port 50 in a small indoor space such as a passenger car, and the suction motor 53 may be installed in the suction port 50 in a wide space such as a factory, a church, an office, a department store, and the like. It is preferable. In addition, in order to quickly remove the heat storage in the room and to form a basic air flow, it is possible to configure a part or all of the intake air to be discharged to the outside for a predetermined time (for example, 30 seconds to 5 minutes) at the beginning of the operation of the cold / hot air fan. .

The opposite side of the suction port 50 of the suction duct 60 is preferably connected to the front of the heat exchanger 40 because the sucked air passes through the heat exchanger 40 and is converted into cold or warm air.

As shown in FIG. 4, the suction port 50 may be installed at the left and right lower sides of the wall opposite to the discharge port 20 by branching the suction duct 60, as well as the left and right wall surfaces opposite the discharge port 20. It is also possible to install in.

In the second embodiment of the natural convection cold and hot air system according to the present invention, as shown in FIG. 5, the suction port 50 is provided without a structure for sucking air in front of the case 10. It consists of a structure for supplying the indoor air sucked through the air blower 30 through the suction duct (60).

In the second embodiment, since the heat is exchanged by sucking the air in the room through the suction port 50 connected to the suction duct 60, the air inlet 18 for suctioning the air toward the case 10 is provided. The circulation of air is made without installing.

In the case of supplying the indoor air sucked through the suction duct 60 toward the blower 30, although not shown in the drawing, it is also possible to supply the inlet of the blower 30, and the blower 30 and the heat exchanger 40 are provided. It is also possible to feed into the space between them.

Also in the above-described second embodiment, the present invention can be implemented in the same configuration as the above-described first embodiment except for the above-described configuration, and thus detailed description thereof will be omitted.

In the third embodiment of the natural convection cold and hot air system according to the present invention, as shown in FIGS. 6 to 8, a part of the indoor air sucked by branching the suction duct 60 toward the blower 30 is shown. Through one or more injection holes 68 which are supplied to and installed in the case 10 above the heat exchanger 40 through one or more branch pipes 62 branching from the suction duct 60. It is discharged from the blower 30 and the blower wind (hot air or cold air) passing through the heat exchanger 40 is made of a configuration to be discharged to interfere at a predetermined period and angle.

The injection hole 68 may be fixed to the case 10 and may be installed to rotate (variable) at a predetermined angle.

By installing the valve 64 in the branch pipe 62 in the above, it is also possible to control the amount of injection air discharged through the injection hole 68 to be equal to each other or to be arbitrarily set at different intervals and angles. .

The branch pipe 62 may be made of a pipe, a hose, or the like, or may be made of a duct.

The angle between the direction of the blowing wind (hot or cold) discharged from the blower 30 and passing through the heat exchanger 40 and the blowing direction of the air discharged through the injection hole 68 is 0 to 180. Set within the range of °.

The angle between the direction of the blowing wind discharged from the blower 30 (or the center line of the longitudinal section of the longitudinal section of the case 10) and the blowing direction of the indoor air discharged through the injection hole 68 are As shown in FIG. 6, it can also be provided so that a predetermined angle (henceforth a side angle (beta)) may be made from a side view. In addition, the angle between the center line of the transverse cross section, which is a horizontal cross section of the case 10, and the jetting direction of the indoor air discharged through the jetting port 68, is a predetermined angle (hereinafter referred to as a planar angle) as shown in FIG. It is also possible to install so as to achieve ().

In addition, the blowing directions of the two or more injection holes 68 are installed to have a predetermined angle to each other, and at the same time, the blower wind is discharged from the blower 30 and passes through the heat exchanger 40 (hot or cold air). It is also possible to install so as to achieve a predetermined angle with the direction of.

It is preferable to set said plane angle (alpha) in the range of 0 degrees <(alpha) <90 degrees, and it is preferable to set said side angle (beta) also in the range of 0 degrees <(beta) <90 degrees.

When the plane angle α and the side angle β are 0 °, the center line of the case 10 and the discharge direction of the injection hole 68 are located in parallel with each other, and the plane angle α and the side angle When (β) is 90 degrees, the center line of the case 10 and the discharge direction of the injection port 68 are located perpendicular to each other.

The plane angle α and the side angle β may be set at the same time, or may be set separately one by one, or may be set to be regularly or irregularly variable using a variable device or an electronic controller. It is also possible to configure the user to set arbitrarily.

As described above, when the discharge directions of the two or more injection holes 68 are installed in the case 10 to form a predetermined angle with each other, the wind discharged from one injection hole 68 and the wind discharged from the other injection hole 68 are different. This causes interference with each other, which causes the dense state of the artificial wind repeated at regular intervals to be disturbed, so that the pressure wave almost disappears or weakens, and the turbulent state of the discharge wind is amplified and proceeds. In addition, the wind blowing from the blower 30 and the wind discharged from the injection hole 68 interfere with each other, and the mechanical regularity (denseness) of the discharge wind is disturbed, and the pressure wave almost disappears or weakens. And the wind softens.

Since the plane angle α and the side angle β are set as described above, it is preferable that the pressure waves of each other cause interference at a predetermined point so that the discharge wind and the blowing wind proceed in a desired direction.

Therefore, it is advantageous to set the plane angle? In the range of 5 to 60 ° in terms of the interference of pressure waves, the direction of travel of the discharge wind, and the blowing wind, and the efficiency.

In addition, it is advantageous to set the side angle beta in the range of 3 to 75 ° in terms of the advancing direction and efficiency of the discharge wind and the blowing wind.

According to the third embodiment of the natural convection cold and hot air system according to the present invention configured as described above, the wind in which the pressure wave is disturbed by the discharge wind of the injection hole 68 is discharged to the discharge hole 20 and the room is discharged. Since it moves and is sucked into the suction port 50, a natural convection is achieved as a whole.

If the position of the suction port 50 is installed below the opposite wall surface of the discharge port 20, the air discharged from the discharge port 20 flows into the suction port 50 through the room, so that convection occurs in the entire room. And the heating and cooling effect is maximized.

In the conventional case, since the flow of air discharged from the discharge port 20 flows back into only the intake port 18 below, convection is not performed throughout the entire room, and convection is locally performed.

Furthermore, in the first to third embodiments of the natural convection cold and hot air system according to the present invention, the air is discharged at a predetermined pressure, similar to the natural wind generated while the air moves by the pressure difference between the high pressure and the low pressure. Since the air is moved by the pressure difference between the discharge port 20 and the suction port 50 that sucks the air in the room at a predetermined pressure away from the discharge port 20, the natural wind having two forces pushing or pulling the air. Like this, the airflow is created by the difference in air pressure, and the natural wind is cool.

Also in the above-described third embodiment, the present invention can be implemented in the same configuration as the above-described first and second embodiments except for the above-described configuration, and thus detailed description thereof will be omitted.

When the discharge direction of the discharge port 20 is formed in three planes as described above, it is possible to evenly send cold or warm air to the entire room.

In the case of the discharge port 20 formed on both side surfaces (A) in the above, it is preferable to install the grill 22 so as to be openable and openable as necessary.

In addition, as shown in Figure 10, the discharge port 20 is also provided long up and down, it is also possible to separately control the direction of the grill 22 so that it is divided into two to three parts to be discharged in different directions, respectively, It is also possible to install so that the grille 22 of lower side D and E can be opened and closed according to this.

10 and 11, it is also possible to provide a branch film 28 so as to divide the flow of air discharged from the discharge port 20 to the heat exchanger 40 in two parts.

When the branch film 28 is provided as described above, it is possible to divide and control the wind discharged to the discharge port 20. That is, it is possible to control the temperature and air volume of the wind passing through the upper (C) grill 22 and the wind passing through the lower (D) and (E) grills 22 differently.

For example, as shown in FIG. 11, the heat exchanger 40 and the blower 30 are respectively divided into two parts, and the operation of each heat exchanger 40 and the operation of the blower 30 are controlled through a control device. By controlling differently, it is possible to adjust the temperature and the air volume of the discharged wind differently. It is preferable that the heat exchanger 40 and the blower 30 which are divided and provided in the above are comprised from 2-8 pieces.

The heat exchanger 40 and the blower 30 may be configured with the same number (for example, two heat exchangers and two blowers, etc.), and may have different numbers (for example, one heat exchanger and two blowers). , Two heat exchangers and one blower).

Although not shown in the drawing, the branch film 28 may be configured to be rotatably fixed to the discharge port 20 by a hinge so that the division of the discharged wind can be changed at a predetermined ratio as necessary.

When configured as described above, it is possible to implement two or more discharge winds of the same or different air volume, wind speed, temperature, etc. in one cold and hot air system. That is, when configured as described above, it is possible to control the discharge direction according to the temperature and intensity of the discharged wind differently, it is possible to implement to match the wind of different temperature and intensity according to the location and taste of the user.

In the case of configuring two or more blowers 30 as described above, the blower winds discharged by installing the blower winds so that the central axes of the blowers 30 have a predetermined plane angle and a side angle with each other interfere with each other, resulting in tissue deformation and turbulence. It is also possible to configure to occur effectively.

The two or more blowers 30 may be installed in a structure in which the central axis is rotated so as to vary the plane angle and the side angle formed from each other. The plane angle and the side angle formed by the two or more blowers 30 as described above are set in a range of about 3 to 60 ° so as to be fixed or variable.

In addition, the two or more blowers 30 may be configured to control each rotational speed in the same manner, or may be configured to rotate at different rotational speeds, and each blower 30 rotates at different periods. It is also possible to configure the speed to be variable.

12 and 13 show an embodiment in which the natural convection cold and hot air system according to the present invention is applied to an air conditioning system of an automobile.

As shown in FIG. 12 and FIG. 13, when the above-described suction port 50 is provided in the middle and / or left and right of the rear seat, respectively, natural convection is achieved in the cabin. In particular, since the interior of the car is very narrow compared to the case of the house, the air flow between the discharge port 20 and the suction port 50 is more directly made, the effect of convection is greatly shown.

And although not shown in the drawings, it is also possible to install the suction port 50 in various places, such as between the driver's seat and the passenger seat and both sides of the rear seat.

Therefore, in the conventional vehicle, the cold air and hot air discharged from the front dash panel do not reach the rear seat sufficiently, so the cooling and cooling time is long and the cooling and heating effect is greatly reduced by applying the natural convection cold and hot air system according to the present invention. The movement of the cold and hot air, that is, the air flow is made smoothly and quickly by the pressure difference like the natural wind, so it is surely improved.

In addition, although the discharge port 20 is installed in a position to avoid the user due to inconvenience in direct contact with the discharge wind for a long time in the automobile, it is possible to adjust the discharge wind temperature and air volume for each discharge port 20, The position and the size can be configured in various ways, and the appearance can be changed.

And in the natural convection cold and hot air system according to the present invention, it is possible to use a combination of various devices for improving the structure and function of the discharge wind, such as antibacterial, deodorant, humidification, discharge, ionization. In other words, it is possible to install various additional devices to improve the user's comfort.

For example, spraying water generated in a heat exchanger (evaporator) with a humidifier and discharging it with a discharge wind during operation with cold wind can prevent drying of indoor air. At this time, the water sprayed by the humidifier can also be sterilized and purified.

In fact, the water generated in the evaporator during the operation of the cold wind is inconvenient to treat this, and it is a very cumbersome task in the indoor unit, it is possible to effectively solve this by installing a humidifier as described above.

In addition, it is possible to improve the user's comfort by additionally installing a discharge device for collecting and discharging static electricity generated in the particles of air during dust collection and blowing.

Furthermore, various methods can be applied to improve the user's comfort as a whole by using cutting-edge science with an interest in the organization of the discharged wind and air.

When the wind (cold or warm) is blown, it always feels cool, warm, and soft, and the skin does not feel sick or swelling. This does not happen.

According to the natural convection cold and hot air system according to the present invention, since the wind is discharged close to the natural wind, it is possible to directly induce the direction of the wind to the part where the person is located, the energy efficiency is high, and the time of cooling and heating is short due to the direct cooling and heating Energy savings. By closing only the intake port of the part which does not need heating and cooling, it is possible to realize the optimum energy saving by operating only the intake port where necessary.

Furthermore, according to the natural convection cold and hot air system according to the present invention, by convection of the convection of the indoor air by installing the inlet facing the opposite side of the discharge port, as well as convection by the pressure difference like the natural wind throughout the room Cooling and heating can be evenly distributed to every corner, and cooling and heating to a far distance is possible even when the discharge amount is small. Therefore, heating and cooling efficiency is increased by more than 15%.

It is possible to control easily.

According to the natural convection cold and hot air system according to the present invention, in the case of the air conditioner, by controlling the collision (mixing) ratio of the wind (indoor air) discharged from the blowing wind and the injection port, the user can easily adjust the discharge wind temperature and the air volume of the cold and hot air Since it is possible to directly lead to the position to be located, it is possible to reduce the energy lost in the conventional luminaire or the upper layer by forming the air flow by inducing the discharge wind downward.
