Description

A suitcase type air-conditioner for cooling and heating the personal environment}

TECHNICAL FIELD The present invention relates to a heating and cooling device, and more particularly, to a bag-type personal air conditioning device which is portable and is capable of providing fresh air cooling and heating airflow individually to a space around a user.

In general, the air conditioner is a device for cooling and heating an indoor space such as a residential space, a commercial space, or an office. The construction and operation of such an air conditioner will be described with reference to FIG. 1 of the accompanying drawings.

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), the outside air blown by the blower fan (3) installed on one side. As a result of the refrigerant gas is liquefied by releasing the 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, the air conditioning effect is not transmitted well in an area far from the air conditioning system, and it is impossible to satisfy all the individual tendencies of everyone in the room. Not only that, there was also an inefficient problem of air conditioning required for heating and cooling.

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 bulky and heavy fixed type to be impossible to carry, in particular, a person must move to another place where the air-conditioning system is not installed outside the room where the air-conditioning system is installed. In this case, there was also a problem that no air conditioning can be expected at all.

Accordingly, the present invention has been made to solve the above problems, by implementing a cooling device in a case, such as a small bag can be equipped with devices such as a notebook computer can be used while being carried by the individual, to the user using the cooling device An object of the present invention is to provide a bag-type personal air conditioner that can individually provide comfortable air-conditioning air.

On the other hand, the personal air-conditioning device of the present invention, precisely controlled to about 20 ℃ to about 23 ℃ temperature that the temperature of the air discharged to the outlet 112a, 112b of the upper compartments (110a, 110b) is the most comfortable for humans This is made possible by the use of a thermoelectric module in which temperature control can be precisely performed as a means of cooling and heating.

In addition, the present invention by switching the electrode connected to the thermoelectric module 130, the heat absorbing portion and the heat dissipating portion is switched to each other, it is possible to simply switch from the cooling function to the heating function.

For reference, the operation principle, configuration and characteristics of the thermoelectric module 130 having the above function will be described 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 emits 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 FIG. 5, the thermoelectric module 130 used in the cooling and heating apparatus of the present invention using this principle includes an upper ceramic plate 131 formed to be in contact with an object Tc to absorb and cool heat. And a lower ceramic plate 132 formed to contact an object Th for dissipating heat, and p-type semiconductors 134 alternately arranged to connect between the upper ceramic plate 131 and the lower ceramic plate 132. And electrically connecting the n-type semiconductor 135 and the p-type semiconductor 134 and the n-type semiconductor 135 together with both ends of the p-type semiconductor 134 and the n-type semiconductor 135. It consists of an electrical cross-connection layer 133 made of copper or the like, which serves as a medium for connecting the plate 131 and the lower ceramic plate 132, the cross-connection layer 133 is connected to a DC power source (P) The current flows through the p-type semiconductor 134 and the n-type semiconductor 135.

Therefore, when the user applies power to cool or heat the object Tc by using the thermoelectric module 130 configured as described above, the current i is connected to the n-type semiconductor ( 135) and p-type semiconductor 134 alternately flows. Accordingly, n-type semiconductor 135 moves electrons (-) in a direction opposite to the direction of current i, while p-type semiconductor 134 In (+), holes move in the direction of current flow.

That is, the electron (-) and the hole (+) are respectively moved from the upper ceramic plate 131 to the lower ceramic plate 132 through the n-type semiconductor 135 and the p-type semiconductor 134, and thus the upper Since the ceramic plate 131 absorbs heat and releases it to the lower ceramic plate 132, the upper ceramic plate 131 acts as a heat absorbing portion, and the object Tc in contact with the upper ceramic plate 131 is cooled. The lower ceramic plate 132 acts as a heat dissipation unit so that the object Th in contact with the lower ceramic plate 132 is heated.

In addition, when the polarity of electricity connected to the thermoelectric module 130 is changed to change the direction of the current, that is, when the parts connected to the positive electrode (+) and the negative electrode (-) of the power source P are interchanged with each other, the phenomenon described above. On the contrary, heat is released from the lower ceramic plate 132 to the upper ceramic plate 131 to switch the heat absorbing portion and the heat radiating portion, 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 characteristics.

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 because it does not use mechanical elements that cause movement.

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.

Sixth, heating and cooling are determined according to the current direction.

Hereinafter, the operation of the cooling and heating device configured as described above will be described.

When the user applies power to cool the surroundings while using the notebook computer 300, the upper ceramic plate 131 of the thermoelectric module 130 connected to the power source in the case 100 becomes a heat absorbing part, and the lower ceramic plate 132 becomes a heat radiating part.

Subsequently, outside air flows into the left and right upper compartments 110a and 110b through the side inlets 111a and 111b by the axial flow fans 113a and 113b of the left and right upper compartments 110a and 110b. The introduced air is discharged through the outlets 112a and 112b while being guided by the guides 114a and 114b while the heat is absorbed by the endothermic action of the upper ceramic plate 131 of the thermoelectric module 130 and cooled. .

At this time, the outside air is introduced into the lower compartment chamber 120 through the front inlet 121 by the crossflow fan 123, the inlet air is the lower ceramic plate 132 of the thermoelectric module 130 After being heated by the heat radiation action of the, through the rear outlet 122 formed in the rear of the compartment compartment 120 is discharged to the opposite side to the user.

On the other hand, when the user wants to heat the air-conditioning device to heat the surroundings of the individual, by switching the electrode connected to the thermoelectric module 130 to convert the upper ceramic plate 131 to a heat dissipation unit and the lower ceramic By converting the plate 132 into a heat absorbing portion, the air introduced into the left and right upper compartments 110a and 110b is heated and discharged, and the air introduced into the lower compartment 120 is cooled and discharged to perform a heating operation. You lose.

By the air-conditioning operation as described above, the user can individually control the heating and cooling of an individual while using a notebook computer or the like.

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-described embodiment, the upper compartments 110a and 110b are partitioned so as to be divided left and right by the vertical dividing wall 150, which are installed at the outlets 112a and 112b, respectively. Air is discharged through the outlets 112a and 112b by being installed at the side inlets 111a and 111b so that the air introduced from both sides is mixed with each other and the airflow characteristics are lowered in the upper compartments 110a and 110b. In order to prevent the non-uniformity, if the axial flow fan (113a, 113b) is installed in each of the outlet (112a, 112b) side partition wall for dividing the upper compartment (110a, 110b) into two parts is not necessary. .

In addition, although the axial flow fans 113a and 113b and the crossflow fan 123 were used as suction means for introducing air into the upper compartments 110a and 110b and the lower compartments 120, Suction means may be used.

According to the present invention as described above, it is possible to implement the air-conditioning device in the case of the bag type, it is easy to carry, can be installed and used in the user's desired place, such as the user's personal desk, according to the user's preferences The user's satisfaction is improved because only the space can be intensively heated and heated.

In addition, the thermoelectric module used in the cooling and heating device of the present invention has an advantage in that accurate temperature control is possible, and the user can precisely control the cold or warm air discharged from the cooling and heating device in a desired state.

In addition, the present invention has no noise and vibration, it is easy to switch from cooling to heating, or from heating to cooling simply by switching the electrode connected to the thermoelectric module.

In addition, since a device such as a notebook computer can be mounted and used in a bag-shaped case, there is an additional effect of protecting these devices or embedding peripheral devices.
