Description

An individual cooling and heating system

The present invention relates to a personal air conditioner, and more particularly, to a personal air conditioner capable of individually providing fresh air cooling and heating airflow to a user.

In general, the air conditioner is a device for cooling and heating an indoor space such as a living space, a restaurant, or an office. The operation of the air conditioner will be described with reference to FIG.

First, the refrigerant gas compressed by the high temperature and high pressure in the compressor (1) is sent to the first heat exchanger (2), and in the first heat exchanger (2) to the outside air blown by the blower fan (3) installed on one side. As the refrigerant gas liquefies by releasing heat of condensation, condensation occurs.

At this time, the hot air passing through the first heat exchanger 2 is discharged to the outside.

Thus, the refrigerant condensed in the first heat exchanger (2) is passed to the second heat exchanger (5) after being reduced to a pressure that is easily condensed and evaporated while passing through the expansion valve (4), and the second heat exchanger (5) In the refrigerant absorbing the external heat while the refrigerant liquid evaporates by the external air blown by the blowing fan (6) installed on one side.

Accordingly, the cooling air deprived of heat while passing through the second heat exchanger 5 is discharged into the room to cool the room. The evaporated refrigerant is a low-temperature low-pressure gas that is sent to the compressor 1 and The same process is repeated.

On the other hand, if you want to heat the room with the air-conditioning device as described above, the refrigerant may be circulated in reverse. In this case, the second heat exchanger (5) acts as a condenser so that warm air flows into the room. The first heat exchanger 2 acts as an evaporator so that cold air is discharged to the outside.

However, since the conventional conventional air conditioning and heating devices are designed to cool or heat the entire indoor space, not only the individual tendency of all people in the room can be satisfied, but the amount of air conditioning required for cooling and heating is inefficient. there was.

In other words, physiologically, the human breathing rate is 0.133 ℓ / s per person, but the standard air conditioner supplied by general air-conditioning system is 10 ℓ / s per person, and the actual amount required by humans is about 1% of the total air conditioning amount. It is only known.

In addition, the conventional air-conditioning device as described above is a bulky and heavy fixed type bar, the air-conditioning effect is not transmitted well in an area far from the air-conditioning device, the person does not have the air-conditioning device is installed outside the room is installed If you need to move to another place to work, there was a problem that you can not expect air conditioning at all.

Accordingly, the present invention has been made to solve the above problems, it is an object of the present invention to provide a personal air-conditioning device that can supply the air-conditioning airflow having a comfortable temperature and humidity to the user in the room individually.

In addition, another object of the present invention is to provide a personal air-conditioning device that is portable for the user to use while moving the place.

In order to achieve the above object, the present invention, the thermoelectric module to absorb heat from the heat absorbing portion by the electrical action to release heat through the heat radiating portion on the opposite side, and the air sucked in contact with the heat absorbing portion of the thermoelectric module Absorbs heat from the first heat exchange chamber and cools the air to flow in a direction opposite to the flow direction of air passing through the first heat exchange chamber in contact with the heat radiating portion of the thermoelectric module. Provided is a personal heating and cooling device that includes a second heat exchange chamber configured to release heat to heat air and then release the heated air, which can be placed on a flat surface of a desk or the like and is portable.

In addition, according to the cooling and heating device of the present invention, by simply rotating the rotation direction of the first and second cross-flow fan in the first and second heat exchange chambers in the opposite direction to the cooling operation, it is possible to simply switch the cooling and heating function, or By switching the polarity of the electricity connected to the thermoelectric module is switched to the heat absorbing portion and the heat dissipation portion, thereby switching between the heat absorbing chamber and the heat dissipation chamber is made to be freely switched to cooling and heating.

Hereinafter, with reference to the accompanying drawings an embodiment of a personal air conditioning device according to the present invention will be described in detail. Each component of the air-conditioning apparatus of the present invention described below is given a name based on the cooling operation, and it is disclosed in advance to help understand that the name of each part does not limit its function.

For example, the inlets and outlets of the respective chambers described below can each function as an outlet and each outlet as an inlet during the heating operation.

As shown in FIG. 2, the personal heating and cooling device of the present invention is connected to a power source (not shown) and absorbs heat from the upper ceramic plate 31 (see FIG. 4) by electric force, thereby lowering the lower ceramic plate 32; 4) and one or more thermoelectric modules 30, which are configured to emit heat through the air, and the upper surface of the upper ceramic plate 31, which is an endothermic portion of the thermoelectric module 30, to be in contact with the air introduced from the outside. It is installed so as to contact the bottom surface of the first heat exchange chamber 10 to absorb the heat and discharge to the outside again, and the lower ceramic plate 32, which is a heat dissipation unit of the thermoelectric module 30 to heat the air introduced from the outside. After the second heat exchange chamber 20 to be discharged to the outside again.

The first heat exchange chamber 10 is provided with an inlet 11 through which air is introduced and an outlet 12 through which the air introduced through the inlet 11 is discharged to face each other. A first cross flow fan (13) and a first drive motor (16) for driving the first cross flow fan (13) are installed so as to be discharged by suction.

In addition, the second heat exchange chamber 20 has a configuration substantially similar to that of the first heat exchange chamber 10, in which the inlet port 21 through which air is introduced from the outside and the air introduced through the inlet port 21 are heated. After the discharge port 22 is discharged again is formed to face each other, there is a second cross-flow fan that rotates in the opposite direction to the first cross-flow fan 13 and forcibly introduces the outside air to discharge (23) and a second drive motor 26 for driving the second cross-flow fan 23 are provided.

That is, the air flow in the second heat exchange chamber 20 is generated to be opposite to the direction of air flow generated in the first heat exchange chamber 10. Accordingly, the second heat exchange chamber 20 and the first heat exchange chamber 20 are generated. The chamber 10 is formed with opposite inlets 21, 11 and outlets 22, 12, respectively.

In addition, the inlet 11 of the first heat exchange chamber 10 is provided with a filter 15 for filtering out foreign substances from the inflowing air and discharging fresh air. It may be optionally installed in the inlet (11, 21) and / or the outlet (12, 22) of each of the first heat exchange chamber 10 and the second heat exchange chamber (20).

In addition, in the outlet 12 of the first heat exchange chamber 10, a wind direction guide 14 formed to be adjustable up and down and / or left and right in order to guide the flow direction of the discharged air is detachably installed and desired by a user. The wind direction can be adjusted in the direction.

Meanwhile, the discharge duct 24 for guiding and discharging the discharged air to the outside may be detachably installed at the discharge port 22 of the second heat exchange chamber 20, so that the second heat exchange chamber 20 may be detachably installed. It is possible to prevent the air discharged from passing into the room again.

Since the discharge duct 24 is detachable, the user may remove and use the discharge duct 24 when the user wishes to move and use the cooling and heating device to another place, and the discharge duct 24 is necessary. In order to prevent the user from entering the cold or warm air into the room through the inlet (11, 21) or the outlet (12, 22) of the first and second heat exchange chamber (10) for heating It is configured to be selectively detachable to (11, 21) or the outlet (12, 22).

In addition, a heat sink 25 connected to one end of the second heat exchange chamber 20 to be pivotable up and down via a hinge shaft 25a may be detachably connected to each other so that the heat of the second heat exchange chamber 20 may be detached. By being transferred to the heat sink 25 it is possible to heat the lower back of the user.

On the other hand, the first heat exchange chamber 10 and the second heat exchange chamber 20 can be switched from the cooling operation to the heating operation by reverse rotation of the first and second cross-flow fan 13, 23 in each chamber. Do.

At this time, it will be understood that the functions of the first and second heat exchange chambers 10 and the functions of the inlets 11 and 12 and the outlets 21 and 22 are reversed.

On the other hand, the personal air-conditioning device of the present invention by switching the electrode connected to the power source of the thermoelectric module 30 which is located between the first heat exchange chamber 10 and the second heat exchange chamber 20, the heat absorbing portion and the heat radiating portion is switched Therefore, the cooling operation and the heating operation can be switched accordingly.

That is, when the user switches the electrode of the thermoelectric module 30 connected to a power source (not shown), the first heat exchange chamber 10 is switched to function as a heat radiation chamber and the second heat exchange chamber 20 is endothermic. It is switched to function as a chamber so that the cooling and heating functions can be switched.

For reference, the structure and operation principle of the thermoelectric module 30 as described above and its characteristics will be described with reference to FIGS. 3 and 4 as follows.

In general, a thermoelectric module is an electrical component based on a semiconductor material that functions as a solid state heat pump. When a current flows in a coupling part connected in series with two different materials, a thermoelectric module generates or absorbs heat at a contact point of two materials. The Peltier Effect is used, and the thermal energy emitted is proportional to the magnitude of the current.

As shown in FIGS. 3 and 4, the thermoelectric module 30 used in the cooling and heating apparatus of the present invention using this principle has an upper ceramic plate formed in contact with an object Tc to absorb and cool heat ( 31), a lower ceramic plate 32 formed to contact the object Th for dissipating heat, and p-type semiconductors alternately arranged to connect between the upper ceramic plate 31 and the lower ceramic plate 32. (34) and n-type semiconductor 35, and p-type semiconductor 34 and n-type semiconductor 35 are electrically cross-connected, and both ends of p-type semiconductor 34 and n-type semiconductor 35 are connected. It consists of an electrical cross-connection layer 33 made of copper or the like serving as a medium for connecting the upper ceramic plate 31 and the lower ceramic plate 32, the cross-connection layer 33 is a direct current power source (P) The current flows through the p-type semiconductor 34 and the n-type semiconductor 35.

Therefore, when the user applies power to cool or heat the object Tc by using the thermoelectric module 30 configured as described above, as shown in FIG. 3, the current i is connected to the cross-connection layer 33. The n-type semiconductor 35 and the p-type semiconductor 34 connected by each other alternately flow, whereby the electron (-) moves in the direction opposite to the direction of the current (i) in the n-type semiconductor 35, In the p-type semiconductor 34, holes (+) move in the direction of current flow.

That is, the electron (-) and the hole (+) are moved from the upper ceramic plate 31 toward the lower ceramic plate 32 through the n-type semiconductor 35 and the p-type semiconductor 34, respectively, and thus Since the ceramic plate 31 absorbs heat and releases it to the lower ceramic plate 32, the upper ceramic plate 31 acts as a heat absorbing portion, and the object Tc in contact with the upper ceramic plate 31 is cooled. The lower ceramic plate 32 serves as a heat dissipation unit so that the object Th in contact with the lower ceramic plate 32 is heated.

In addition, when the polarity of the electricity connected to the thermoelectric module 30 is changed to change the direction of the current, that is, if the parts connected to the positive electrode (+) and the negative electrode (-) of the power supply P are interchanged with each other, the phenomenon described above. On the contrary, heat is released from the lower ceramic plate 32 toward the upper ceramic plate 31 so that the heat absorbing part and the heat radiating part are switched, and the magnitude of the heat energy absorbed and radiated can be changed by changing the magnitude of the supplied current. Will be understandable.

On the other hand, the thermoelectric module has the following advantages.

First, accurate temperature control is possible, because the magnitude of heat energy absorbed and dissipated is proportional to the amount of current supplied.

Second, there is no noise and vibration.

Third, it is compact and light.

Fourth, local air-conditioning is possible.

Fifthly, it is environmentally friendly since no CFC gas or any refrigerant is used.

Hereinafter, the operation of the air conditioner having the above configuration will be described.

First, the cooling operation of the air conditioner is described.

When the user applies the power to the heating and cooling device of the present invention to operate the thermoelectric module 30 and to drive the first and second cross-flow fan 23 coupled to the first and second drive motor 26, the first cross-flow The outside air is introduced by the fan 13 through the first heat exchange chamber 10 through the inlet 11, and the introduced air passes through the first heat exchange chamber 10 of the thermoelectric module 30. Heat is taken away by the upper ceramic plate 31, which is an endothermic portion, is cooled, and then discharged through the outlet 12 to supply cold air to the user.

At this time, the air supplied into the first heat exchange chamber 10 is filtered by the filter 15 installed just inside the inlet 11, and the cold air discharged through the outlet 12 is discharged 12. It is discharged toward the user by the wind direction guide 14 installed immediately behind it can be cooled around the user.

Meanwhile, the second heat exchange chamber 20 generates air flow flowing in a direction opposite to the air flow in the first heat exchange chamber 10 and releases heated air, that is, the second cross flow fan ( The air toward the user flows through the inlet 21 through the inlet 21 and is heated by the thermoelectric module 30 while passing through the second heat exchange chamber 20, and then discharged through the outlet 22.

At this time, since the discharge duct 24 can be attached and detached to the rear of the discharge port 22 according to the user's needs, when the user wants to discharge the air to the outside, the discharge duct 24 connected to the outdoor is attached and heated. Air can be discharged to the outside.

Next, the heating operation of the air conditioner of the present invention will be described.

If the user wants to heat the surroundings, the first and second drive motors 16 and 26 in the first and second heat exchange chambers 10 and 20 are driven in the opposite manner as in the cooling operation. (13, 23) by rotating in the opposite direction to reverse the role of the first and second heat exchange chambers (10, 20), or the electrodes of the thermoelectric module 30 may be interchanged.

First, when reverse rotation of the first and second cross-flow fan (13, 23), after the outside air flows through the outlet 12 of the first heat exchange chamber 10 is cooled, Cold air is discharged through the inlet 11, and external air is introduced into the second heat exchange chamber 20 through the outlet 22 to be heated, and then warm air is discharged through the inlet 21.

At this time, the wind direction guide 14 mounted on the outlet 12 of the first heat exchange chamber 10 is mounted on the inlet 21 of the second heat exchange chamber 20 and discharged through the inlet 21. It is desirable to adjust the warmth to the user.

In this case, the heat dissipation plate 25 may be attached to the lower portion of the second heat exchange chamber 26 to transfer the heat of the second heat exchange chamber 20 to heat the lower part of the user's body.

On the other hand, in the case of switching the electrodes of the thermoelectric module 30 to switch the heating and cooling function, the lower ceramic plate 32 of the thermoelectric module 30 functions as a heat absorbing portion to absorb heat, the upper ceramic plate 31 The second heat exchange chamber 20 serves as an endothermic chamber to discharge cooling air, and thus the first heat exchange chamber 10 serves as a heat radiating chamber. By releasing air, the surroundings are heated.

On the other hand, the present invention is not limited to the above-described embodiment, and various changes and implementations can be made without departing from the gist of the present invention.

For example, in the above embodiment, a cross flow fan is used as a means for sucking air into the chambers, but various fans such as an axial fan may be used according to the needs of the user.

As described above, according to the present invention, since a small thermoelectric module that is electrically operated as a cooling and heating means is used, the size of the cooling and heating device can be varied in consideration of the portable and air-conditioning performance, and a user such as a user's desk. It is easy to install at a desired place, and thus the user's satisfaction can be improved because only the space around the user can be concentrated and heated according to the user's disposition.

In addition, the thermoelectric module has an advantage in that accurate temperature control is possible, and the user can precisely control the cold or warm air discharged from the air conditioning apparatus in a desired state.

In addition, the present invention has no noise and vibration, the operation of switching the electrode connected to the drive motor or the thermoelectric module for driving the cross-flow fan is easy to switch from simply cooling to heating, or heating to cooling.
