Description

Air conditioner for collecting of waste heat useing heat pipe

The present invention relates to an air conditioner, and more particularly, in order to ventilate an indoor room using an air conditioner, when exhausting indoor air to outside and introducing outdoor air into the room, the waste heat of the indoor air exhausted by using a heat pipe is recovered. By allowing heat to be introduced into the room after the heat exchange with the outside air, the waste heat recovery type air conditioner using a heat pipe to minimize energy loss.

Recently, air pollution has become serious with the development of the industry, and air conditioners have been developed to maintain a comfortable indoor space while maintaining health from such air pollution.

The air conditioner is installed for the purpose of cooling or heating the room or purifying the air with a heater, an air conditioner, an air purifier, etc., and serves to create a more comfortable indoor environment for humans.

That is, it creates a pleasant atmosphere for human activities by controlling the temperature, humidity, and airflow of the indoor space, and further, creates a pleasant indoor environment by filtering and collecting dust contained in the indoor air in the process of circulating the indoor air. Done.

Such an air conditioner sucks air inside and outside by the suction force of a blower fan, heats or cools the air sucked through the heat exchanger, and discharges the air again to the room, thereby performing a cooling and heating function.

A schematic configuration of the above-described conventional air conditioner will be described below with reference to FIGS. 1 and 2.

As shown, a conventional air conditioner includes an air conditioner body portion; A circulating air intake space 21 having a circulating air suction port 21 through which the circulating air is sucked into one side of the air conditioner body part together with a damper 23, and a suction fan member 22 installed therein; An exhaust space portion 30 which communicates with the circulating air suction space portion 20 and exhausts some of the air introduced therein to the exhaust port 31 provided with a damper 32; Air is introduced from the exhaust space part 30 through the mixing damper 41, and the outside air mixing space part 40 is introduced into the outside air suction port 43 under the control of the outside air damper 42. ; A filter device (50) installed near the outside air mixing space (40) and filtering the sucked mixed air; A heat conversion device (60) installed inside the filter device (50) to cool or heat air passing through the filter device; Humidifier 80, which is installed in proximity to the heat conversion device 60 to spray water to humidify the water, and an air vent 71 is formed on one side thereof, and the air cooled or heated therein through the air vent. And a blowing space part 70 in which a blowing fan member 72 forcibly sending out is provided.

That is, as described above, the suction fan member 22 and the filter device 50, and the heat conversion device (1) at one side of the air conditioner 10, the circulating air inlet 21 for sucking the outside air into the air conditioner body part. 60 is installed in series so that the outside air sucked through the circulating air inlet 21 of the circulating air suction space 20 is sequentially filtered through the filter device 50, and then the heat conversion device 60. The blower fan member 72 of the blower space part 70 is heated or cooled to an appropriate temperature by air, and the air heated or cooled in this manner is kept at a suitable humidity by the water sprayed from the humidifier 80. It is sent to the air vent through (71).

As described above, in the state where the damper 23 of the circulating air inlet 21 is opened and the circulating air is introduced into the intake space 20, the damper 32 and the outside air inlet of the exhaust port according to the degree of air pollution in the room. What is necessary is just to adjust the opening amount of the damper 42 and the mixing damper 41. FIG.

The damper 32 of the exhaust port and the damper 42 of the outside air intake port have the same opening force, and the mixing damper 41 located between the exhaust space part 30 and the outdoor air mixing space part 40 is formed in the exhaust port. The damper 32 and the damper 42 of the outside air suction port have an opening force opposite to that of the damper 32.

Therefore, when the circulating air is discharged due to contamination of the indoor air and the fresh air from the outside is introduced, the damper 32 of the exhaust port and the damper 42 of the external air intake port may be opened.

At this time, when the opening amount of the damper 32 of the exhaust port is 50%, the damper 42 of the outside air intake port is also opened by 50%, and the mixing damper 41 or 50 which is located between the exhaust space part and the outside air mixing space part is also opened. .

That is, as described above, the damper 32 of the exhaust port and the damper 42 of the outside air inlet are equally opened, and the damper 32 of the exhaust port and the damper 42 and the mixing damper 41 of the outside air intake port are the same. It is because it has the opposite opening power.

Accordingly, when the opening amount of the damper 32 of the exhaust port is 10%, the damper 42 of the outside air intake port is also opened by 10%, and the mixing damper 41 is opened by 90%.

On the contrary, when the opening amount of the damper 42 of the exhaust port is 90%, the damper 42 of the outside air intake port is also opened by 90%, and the mixing damper 41 is opened by 10%.

According to the above function, if the indoor air pollution degree is high, and the indoor air is exhausted a lot, and the air inlet damper 32 and the air intake damper 42 are opened 50% to introduce a lot of fresh air, the mixing damper ( 41) It is also opened 50%, when the circulating air introduced into the suction space 20 through the circulating air suction port is transferred to the exhaust space 30 by the suction fan member 22, a part of air (approximately 50%) is discharged to the exhaust port 31 through the exhaust port damper 32, and the remaining part (approximately 50%) is introduced into the outdoor air mixing space 40 through the mixing damper 41.

Thus, some of the circulating air introduced into the outdoor air mixing space 40 is mixed with fresh external air (approximately 50%) introduced through the damper 42 of the outdoor air inlet, and then the filter device 50 and the heat exchanger ( 60) and after the heat exchange through the humidifier 80, etc., is discharged to the room via the air blower 71 by the blower fan member 72.

As described above, a part of the circulating air is continuously exhausted to the outside, and as a result, ventilation is naturally performed through the process of continuously introducing fresh air into the room.

In this case, the ventilation amount of the indoor air can be adjusted by adjusting the opening amounts of the exhaust port damper 32 and the outside air intake damper 42.

That is, when the ventilation amount of the indoor air is to be reduced, the opening amount of the exhaust port damper 32 and the outside air intake damper 42 is reduced to reduce the intake of the indoor air and the intake of external air, and conversely, to circulate the air conditioner. This can be done by continuously circulating a lot of air.

For example, if the exhaust port damper 32 is opened by about 10% in order to ventilate the indoor air only a little, the outside air intake damper 42 is also opened by 10%, and conversely, the mixing damper 41 is opened by 90%.

Accordingly, about 90% of the circulated air moved to the exhaust space part through the suction space part is moved to the outside air mixing space part through the mixing damper 41, and only about 10% of the circulated air is discharged to the outside through the exhaust port 31. do.

On the contrary, the outside air intake damper 42 is also opened by about 10%, and as much as 10% of external air is introduced, mixed with about 90% of circulating air, and then transferred to the blower space part.

On the other hand, when the pollution degree of the indoor air is very large and the exhaust air damper 32 is opened 100% to ventilate most of the indoor air, the external air intake damper 42 is also opened 100%, on the contrary, the mixing damper 41 is completely It is closed.

Therefore, all of the air circulating in the room is discharged to the outside through the exhaust port 31, and 100% of fresh air is introduced into the air conditioner to circulate the room.

However, the conventional air conditioner having the above configuration has a problem in that heat loss is generated as the indoor air is ventilated due to pollution of indoor air, resulting in a large power consumption due to a decrease in efficiency.

In other words, when the indoor air is ventilated due to pollution of the indoor air being cooled during the hot summer season, the indoor air of low temperature escapes through the exhaust port, and the high temperature outside air flows into the room through the air intake port. Since the temperature of the bar is increased, there is a problem that the energy consumption of cooling the room air is increased by heat exchange again.

On the contrary, even when the indoor air is ventilated due to pollution of the heated indoor air in the cold winter season, the high temperature indoor air escapes to the outside through the exhaust port, and the low temperature outside air flows into the interior through the outside air intake, The overall temperature of the indoor air is lowered, there was also a problem that the energy consumption of heating the room air is lowered by heat exchange again.

The present invention has been made in view of the above problems, and minimizes the temperature change of the indoor air in the process of ventilating the indoor air with the outside air according to the pollution of the indoor air during the cooling or heating of the room using the air conditioner Thus, the purpose is to provide a waste heat recovery type air conditioner using a heat pipe to reduce the heat loss of the indoor air to reduce the power loss due to energy consumption.

That is, when the indoor air is ventilated during a cooling operation in a hot summer room, the hot air from the outside is recovered as waste heat of the cold air exhausted as the air flows into the room, thereby allowing the heat exchange to flow into the cold air. On the contrary, when the indoor air is ventilated during the heating operation in the cold winter season, the waste heat of the indoor hot air that is exhausted as the cold air flows into the indoor air is recovered to allow the heat to flow into the warm air according to the heat exchange. The purpose of the present invention is to provide a waste heat recovery type air conditioner using a heat pipe that reduces heat loss and eventually reduces power loss due to energy consumption.

Waste heat recovery type air conditioner using a heat pipe according to the present invention for achieving the above object, circulating air suction space portion; An exhaust space portion communicating with the circulating air intake space portion and exhausting some air introduced into the exhaust air to the exhaust port; And a mixed space unit for mixing the air introduced from the exhaust space and the outside air introduced through the outside air inlet, and a plurality of heat pipes are bent based on the center of the exhaust space of the exhaust space and the outside air inlet of the mixed space. The heat pipe module is installed to be inclined upwardly on both sides, and the heat pipe module is installed in communication with an exhaust duct of an exhaust port and an air intake duct of an external air inlet by a bellows tube that is expandable and contracted, respectively. The installation is made at an inclined angle upward or downward, characterized in that the indoor air exhausted through the exhaust port and the outside air sucked through the outside air intake port are not mixed with each other.

Herein, the heat pipe module is located at an inclined upward angle by a large angle with respect to a partition wall partitioning an exhaust space portion and a mixed space portion during a summer cooling operation, and a portion located at an outside air intake side is located at the partition wall. It is preferable to be fixed and installed so as to be inclined downward by a horizontal or small angle relative to,

During winter heating operation, the part located on the exhaust port is inclined downward by a small angle with respect to the partition wall partitioning the exhaust space and the mixed space part, and the part located on the outside air inlet port is inclined upward by a large angle based on the partition wall. It is desirable to be fixed and installed to position.

On the other hand, the shielding portion is extended by a predetermined length from the bent center portion of the heat pipe module, the guide wall is formed in the partition wall between the exhaust space and the mixed space portion to a certain depth, the shielding portion of the heat pipe module According to the seesaw movement, it is preferable to be configured to continuously shield the exhaust space portion and the mixed space portion while ascending and descending by a predetermined interval in the guide groove of the partition wall.

In this case, it is preferable that the shielding part is made of a soft material such as rubber to have a predetermined elasticity.

As described above, according to the waste heat recovery type air conditioner using the heat pipe according to the present invention, during the cooling or heating the room using the air conditioner, the indoor air in the process of ventilating the indoor air with the outside air according to the pollution of the indoor air By minimizing the temperature change of the air, the heat loss of the indoor air is reduced, thereby reducing the power loss due to energy consumption.

For reference, in describing the embodiments of the present invention, the same parts as in the related art will be described with the same reference numerals, and repeated description thereof will be omitted.

First, as shown in Figure 3, the waste heat recovery type air conditioner using a heat pipe according to the present invention, the exhaust port 31 formed on the upper side of the exhaust space 30, and the mixing space portion 40 on one side A heat pipe module 100 in which a plurality of heat pipes 104 are arranged is provided over the formed outside air intake port 43.

Here, the heat pipes 104 have a structure that is arranged to be inclined in both directions from the center of the cutting edge portion of the center of the V-shaped approximately from the middle.

That is, as shown in FIG. 4, the heat pipe module 100 is bent in a V-shape from the middle thereof, and the heat pipes 104 are formed to be inclined with respect to one of the plurality of heat pipes 104. The cover 102 surrounds the heat pipes 104, and both sides of the cover 102 are configured to communicate with each other by opening the upper and lower surfaces thereof.

Here, both upper opening portions of the heat pipe module 100 are installed in communication with the exhaust duct of the exhaust port 31 and the air intake duct of the external air intake port 43 by the bellows pipe 110 that can be expanded and contracted, respectively. Accordingly, the seesaw movement of the heat pipe module 100 is possible from the central portion thereof.

That is, the portion of the heat pipe module 100 positioned on the exhaust port 31 side may be inclined at a horizontal or small angle, and the portion of the heat pipe module 100 may be fixed to be inclined at a large angle. On the contrary, the portion located on the exhaust port 31 may be fixed to maintain the inclined state at a large angle and the portion located on the outside air inlet 43 may be inclined at a horizontal or small angle.

Here, the heat pipe module 100 by one of the seesaw movement to form a state inclined at a horizontal or small angle, and the other to achieve a state inclined at a large angle will vary depending on the season, Similarly, the lifting means 200 for seesawing the heat pipe module 100 is provided.

The lifting means 200 is lifted by the driving unit 202 which is installed on one side of the upper space of any one of the exhaust space portion 30 or the mixed space portion 40, and the driving of the driving unit 202, The end of the heat pipe module 100 is composed of a connecting portion 204 fixedly installed on one side of the upper cover edge side.

For example, as shown in FIGS. 7A and 8A, a driving unit 202 is installed at an upper side of the mixing space part 40, and an end of the connection part 204 connected to the driving part 202 is mixed space part 40. In the case where the heat pipe module 100 is fixedly installed at one side of the upper cover edge side of the heat pipe module 100, the heat pipe module 100 may perform a seesaw motion by the operation of the elevating means 200.

That is, when the driving unit 202 of the elevating means 200 is pulled forward and the connecting portion 204 is pulled up, as shown in FIG. 8A, a portion located in the mixing space portion 40 side of the heat pipe module 100. Is inclined upward relative to the center thereof, and thus the portion located toward the exhaust space 30 is inclined downward in a horizontal or small angle. On the contrary, when the driving unit 202 of the elevating means 200 is rotated backward to lower the connecting unit 204, as shown in FIG. 7A, the heat pipe module 100 is positioned toward the mixing space 40. The portion to be inclined downward in a horizontal or small angle relative to the center thereof, and thus the portion located toward the exhaust space portion 30 is inclined upward at a large angle.

For reference, in the embodiment of the present invention, the lifting means 200 has been described as an example consisting of the driving unit 202 and the connecting portion 204, the lifting means can be implemented by a variety of configurations, of course. That is, although not separately shown, a turnbuckle may be installed between the cover both sides of the heat pipe module 100 and the upper one side of the exhaust space 30 or the mixed space 40 to allow the lifting to be performed. The pneumatic cylinders may be elevated to be inclined.

In addition, the heat pipe module 100 may be lifted by a ball screw and a lifted by folding of multiple links, as well as the lifting may be made to be inclined by a combination of various known mechanical and electrical components. Of course.

Here, as the heat pipe module 100 performs the seesaw movement by the elevating means 200 based on the center thereof, a constant gap is formed in the partition wall 210 of the exhaust space part 30 and the mixed space part 40. It can only happen.

That is, there is no problem when the heat pipe module 100 is formed horizontally, but as described above, the heat pipe module 100 is formed in a V shape, and the seesaw movement is performed based on the center of the bent portion. Although one of the lower points is connected to the partition wall 210 of the exhaust space 30 and the mixed space 40 by the hinge 212, the other part is partition wall 210 according to the seesaw motion. ) Is separated from the vertical line and the gap is bound to occur.

Therefore, in the embodiment of the present invention, even if the heat pipe module 100 performs the seesaw motion, shielding means for shielding the exhaust space 30 and the mixed space 40 is further provided.

As shown in FIGS. 3 to 4b, the upper point is fixedly installed by the partition wall 210 and the hinge of the exhaust space 30 and the mixed space 40 at the center of the bent portion of the heat pipe module 100. It is. In addition, the shield portion 214 extends in the vertical direction by a predetermined length from the center of the bent portion to the lower point, the shield portion 214 is made of a soft, rubber-like to have a predetermined elasticity. Here, the guide groove 216 is formed in the partition wall on the upper side of the mixing damper 41 between the exhaust space part 30 and the mixing space part 40 by a predetermined depth, and the shielding part 214 is a heat pipe. According to the seesaw motion of the module 100, the exhaust space part 30 and the mixed space part 40 are continuously shielded while being elevated by a predetermined interval in the guide groove 216 of the partition wall 210.

The shielding portion 214 is formed to extend into the cover 102 of the heat pipe module 100 so as to partition the both sides (condensation portion and evaporation portion) of the heat pipe 104 so that the shielding is made 215 ) Is extended, and the heat pipe passage hole 215a is formed in the blocking film 215.

Therefore, only the fluid in the heat pipe 104 is moved to the condensation part and the evaporation part, and the air passing through the condensation part of the heat pipe 104 and the air passing through the evaporation part of the heat pipe 104 are the blocking film of the shielding part. By the heat insulation part formed by 215, it does not mix with each other.

At this time, the shielding portion 214 is made of a soft material such as rubber is applied, the heat pipe module 100 is a seesaw movement starting from the hinge to the exhaust space portion 30 side or mixed space portion 40 Even if it is biased toward the side, it is positioned inside the guide groove 216 of the partition wall 210 while maintaining elasticity, thereby shielding the exhaust space portion 30 and the mixed space portion 40 continuously.

On the other hand, the heat pipe 104 in the heat pipe module 100 to be applied to the present invention, as a heat transfer means is already widely used in industrial fields such as electricity, electronics and agriculture, etc., in the vacuum metal tube It is manufactured by injecting working fluid such as inert gas with low boiling point and large latent heat of evaporation.It is a device that transfers heat as latent heat during phase change by using the feature that the working fluid easily changes from liquid to vapor under low pressure conditions. .

Heat pipes are used as efficient heat transfer elements for general air conditioning and air conditioning, cooling of electronic devices, waste heat recovery in the temperature range, and solar heat collection.The advantage is that they can achieve up to thousands of times of heat conduction performance without a separate power source. Is there.

As shown in FIGS. 5 and 6, the heat pipe 104 is composed of a sealed container 104a, a working fluid 104c such as a capillary 104b, and an inert gas, and a working fluid 104c. The gas-liquid interface is curvature and capillary pressure is generated by the difference in the radius of curvature of the closed container 104a. The liquid condensed in the condensation unit is transported to the evaporator by the capillary pressure. Thermosyphon phenomenon occurs.

That is, the heat pipe 104 has a curvature of the condensate interface accumulated inside the capillary tube due to the difference between the vapor pressure in the capillary tube 104b and the pressure of the condensate. This curvature decreases as it moves toward the end of the condenser and increases towards the end of the evaporator. The vapor pressure is at its maximum in the evaporator and gradually decreases to its minimum at the insulator. The pressure then slowly increases up to the condensate. Therefore, the steam flow rate is accelerated in the evaporator and reaches the maximum speed in the adiabatic section, and the flow rate decreases again due to the condensation process.

The condensation pressure is large in the condensation section where condensation is active and the condensation pressure is small in the evaporation section where the liquid is relatively small. The movement of the condensate generates capillary pressure to balance the force due to the interfacial curvature caused by the pressure difference between the vapor and the condensate. This capillary pressure acts as a force for pumping the condensate condensed on the condensate into the evaporator.

However, when the heat pipe module 100 is in a horizontal state, the condensed liquid condensed in the plurality of heat pipes 104 provided in the heat pipe module 100, that is, the condensation part, is easily moved along the capillary tube 104b to the evaporation part. Since the thermosiphon phenomenon does not occur properly as it is not moved, a problem may occur that eventually does not achieve a smooth heat exchange.

That is, when the heat pipe module 100 is cooled horizontally in a state in which the heat pipe module 100 is horizontally installed over the exhaust port 31 and the outside air intake port 43, the exhaust portion that communicates with the exhaust port 31 in the heat pipe module 100. Form a condensation portion, and the outside air suction portion communicating with the outside air suction port 43 forms an evaporation portion.

That is, during the cooling operation, when the exhaust port 31 and the outside air intake port 43 are opened for ventilation, the indoor cold air is exhausted to the outside through the exhaust port 31, so that the exhaust portion of the heat pipe module 100 is cooled. It is formed of a condensation unit that exhausts warm air to the outside by heat exchange with the air, and the outdoor hot air is introduced into the room through the outside air intake port 43, whereby the outside air intake portion of the heat pipe module 100 is introduced into the hot air. It is formed by an evaporator that heat exchanges and supplies cold air to the room.

At this time, the condensate condensed by heat exchange in the condenser of the heat pipe module 100 is moved to the evaporator by the thermosyphony phenomenon, and on the contrary, the working fluid evaporated by heat exchange in the evaporator must also be moved to the condenser by the thermosyphony phenomenon. However, as described above, when the heat pipe module 100 is horizontal, the thermosiphon phenomenon is not smoothly performed, which causes a problem in that efficiency is lowered.

Thus, by forming the heat pipe module 100 to be inclined according to the cooling operation or the heating operation of the air conditioner 10, it is preferable to maximize the efficiency by making the thermosyphon phenomenon smoothly.

In particular, the evaporator has a horizontal or relatively inclined angle with respect to the horizontal, and the condensation portion has a relatively inclined angle inclined so as to increase the heat exchange area of the air to the evaporator, conversely condensate of the condensate maximizes gravity It is preferable to make the movement to the evaporator at a high speed.

For reference, it is preferable that the coil 104d is wound around the outer circumferential surface of the heat pipe 104 of the heat pipe module 100 so as to widen the contact area with the air passing therethrough to improve heat exchange efficiency. Instead of increasing the contact area with air such as pins and increasing the contact time, any one can be attached and installed.

<Cooling operation in summer>

Figure 7a is an enlarged configuration diagram showing the installation relationship of the heat pipe module 100 during the indoor cooling operation in the summer, Figure 7b is an operation flowchart showing a heat exchange process according to the installation configuration of Figure 7a.

As shown, when the indoor cooling operation in the summer, the heat pipe module 100 is installed to be inclined downward from left to right using a driving means. That is, the exhaust portion located on the exhaust port 31 side is inclined upward at a large angle from the partition wall 210 partitioning the exhaust space portion 30 and the mixing space portion 40 and positioned at the outside air intake port 43 side. The outside air suction portion is installed to be inclined downward or horizontally at an angle smaller than the exhaust portion starting from the partition wall 210.

Therefore, in the heat pipe module 100, the exhaust part located on the exhaust port 31 side becomes the condensation part, and on the contrary, the outdoor air suction part located on the outside air intake port 43 side becomes the evaporation part.

At this time, the heat pipe module 100 is tilted by the lifting means 200 is adjustable in position can be fixed, it is installed so as to communicate with the bellows pipe 110 is stretchable for each exhaust duct and the outside air suction duct. It is possible to install inclined according to the lifting.

That is, when the driving unit 202 of the driving means 200 is driven to lower the connecting unit 204, the exhaust pipe of the heat pipe module 100 moves upwards, and the intake air moves downward to be inclined as described above. Will be achieved.

As described above, the heat pipe module 100 is installed at the exhaust port 31 to be high and lower at the outside air intake port 43 so as to be inclined, so that the indoor air is polluted and ventilated to exhaust the air outlet 31 and the air intake port 43. 7), as shown in FIG. 7B, fresh air from the outside is supplied to the room through the outside air intake port 43, and the indoor air corresponding to the supplied amount is exhausted to the outside through the exhaust port 31. do.

At this time, the indoor cold air passes through the exhaust portion of the heat pipe module 100 through the exhaust port 31, and the cold air passes through the exhaust portion of the heat pipe module 100 to exchange heat to condense the working fluid. The condensed water condensed by heat exchange with cold indoor air discharged is transported to the evaporator through a heat insulation along a capillary tube inclined downward at a large angle.

That is, as described above, the condensed water condensed at the exhaust portion in which the exhaust portion of the heat pipe module 100 is inclined upward with respect to the partition wall 210 is easily transported to the evaporation portion according to gravity. At this time, the exhaust portion of the heat pipe module 100 is inclined at a large angle, the gravity acts more greatly, so that the condensate can be transported more quickly.

On the other hand, the outdoor air in the summer to maintain a high temperature, the outdoor hot air passes through the intake portion, that is, the evaporation portion of the heat pipe module 100 through the outside air intake port 43, the evaporator heats the heat of the outside air, i.e. It is supplied to the room with cold air. The working fluid vaporized by the heat exchanged with the hot air sucked in by this is circulated to the exhaust part, that is, the condensation part through the thermal insulation barrel by synergy.

Here, the evaporator is formed to be inclined at a relatively small angle or horizontally compared to the condenser, so that the cross-sectional area in which the outside air contacts is relatively widened, thereby increasing heat exchange efficiency.

Therefore, the outdoor hot air, ie, the outside air, becomes heat exchanged through the outside air suction portion of the heat pipe module 100 to form cold air, and as the cold air flows into the room, heat loss of the indoor air due to ventilation is reduced. As a result, it is not necessary to increase energy consumption in order to lower the temperature of the indoor air, so that power costs do not increase.

Here, the cold air in the room passes through only the condensation part of the heat pipe module 100 through the exhaust space part 30, and exhausts only to the outside through the exhaust duct. In contrast, the external hot air is heated through the outside air inlet. Only through the evaporation unit of the module 100 passes through the mixing space 40, the intake is made, so that the cold indoor air exhausted and the hot air sucked in are not mixed with each other.

That is, the condensation part and the evaporation part of the heat pipe module 100 have a structure that is not in communication with each other by the heat insulating part in the middle, and even if the inclination angle of the heat pipe module 100 forms a soft windshield exhaust space part ( 30 and slides on the guide groove formed in the partition wall of the mixing space 40 to completely shield the exhaust space 30 and the mixing space 40, the air of different temperatures flowing in and out do not mix with each other Heat exchange efficiency is further improved.

<Winter heating operation in winter>

8A is an enlarged configuration diagram illustrating an installation relationship of the heat pipe module 100 during a winter heating operation, and FIG. 8B is an operation flowchart illustrating a heat exchange process according to the installation configuration of FIG. 8A.

As shown, when the heating operation in the winter room, the heat pipe module 100 is installed to be inclined upward from the left to the right by using a driving means. That is, the exhaust portion located on the exhaust port 31 side is inclined upward at a horizontal or small angle from the partition wall 210 partitioning the exhaust space 30 and the mixed space 40, and the outside air inlet 43. The outside air suction portion located at the side is installed to be inclined upward at an angle greater than the exhaust portion starting from the partition wall 210.

Therefore, in the heat pipe module 100, the exhaust part located on the exhaust port 31 side becomes the evaporation part, and on the contrary, the outdoor air suction part located on the outside air intake port 43 side becomes the condensation part.

At this time, the heat pipe module 100 is adjustable inclined by the lifting means can be fixed, it is installed in communication with the bellows pipe 110 is stretchable for each exhaust duct and the outside air suction duct. It is possible to install inclined according to the elevation.

That is, when driving the driving unit 202 of the driving means 200 to raise the connecting portion 204, the exhaust pipe in the heat pipe module 100, the intake portion is moved upward to inclined as described above Is achieved.

As described above, the heat pipe module 100 is installed at a low position in the exhaust port 31 and high at an external air intake port 43 so as to be inclined. ), As shown in FIG. 8B, fresh air from the outside is supplied to the room through the outside air intake port 43, and the indoor air corresponding to the supplied amount is exhausted to the outside through the exhaust port 31. do.

At this time, the warm air in the room passes through the exhaust part of the heat pipe module 100 through the exhaust port 31, and the warm air passes through the exhaust part of the heat pipe module 100 to exchange heat to evaporate the working fluid. The working fluid evaporated by the heat exchange with the warm indoor air discharged is transported to the condensation unit through the heat insulation along the capillary tube inclined upward at a horizontal or small angle.

On the other hand, the outdoor air in the winter to maintain a low temperature, the outdoor cold air is passed through the outside air suction portion of the heat pipe module 100 through the outside air intake port 43, the cold air intake of the outside air of the heat pipe module 100 The heat exchange passes through the site to condense the evaporated working fluid, and the working fluid condensed by the cold air being sucked in and the heat exchange is circulated to the exhaust part, that is, the evaporation part through the heat insulation along the capillary tube inclined downward in a large slope.

That is, as described above, the condensed water condensed at the suction part in which the suction part of the heat pipe module 100 is inclined upward at a large angle with respect to the partition wall 210 is easily transported to the evaporator part by gravity. . At this time, the suction portion of the heat pipe module 100 is inclined at a large angle, the gravity acts more and the transport of condensate is made faster.

Here, the evaporator is formed to be inclined at a relatively small angle or horizontally compared to the condenser, so that the cross-sectional area in which the outside air contacts is relatively widened, thereby increasing heat exchange efficiency.

Therefore, the outdoor cold air, ie, the outdoor air, becomes a warm air through heat exchange while passing through the outside air intake portion of the heat pipe module 100. As the warm air flows into the room, heat loss of the indoor air due to ventilation is reduced. As a result, it is not necessary to increase the energy consumption in order to increase the temperature of the indoor air, so that the power cost does not increase.

Here, the indoor warm air passes only through the evaporation part of the heat pipe module 100 through the exhaust space part 30 and exhausts only to the outside through the exhaust duct, whereas the external cold air is heat pipe through the outside air inlet. Only through the condensation part of the module 100 passes through the mixing space part 40, and thus the intake is made, so that the warm indoor air exhausted and the cold outside air sucked in are not mixed with each other.

That is, the evaporation part and the condensation part of the heat pipe module 100 have a structure in which they are not communicated with each other by the heat insulating part in the middle thereof, and even if the inclination angle of the heat pipe module 100 is achieved, the soft windshield is the exhaust space part ( 30 and slides on the guide groove formed in the partition wall of the mixing space 40 to completely shield the exhaust space 30 and the mixing space 40, the air of different temperatures flowing in and out do not mix with each other Heat exchange efficiency is further improved.

For reference, although not separately shown, a protractor may be installed at one central side of the heat pipe module 100 to visually check the inclined angle of the heat pipe module 100.

The reason for this is that when the inclination angle of the heat pipe module 100 is performed in the summer or winter time, after grasping whether the heat exchange efficiency is the most excellent, the setting is made easy at the angle having the most heat exchange efficiency.

9A and 9B illustrate a state in which the heat pipe module 100 is not formed to be inclined in both directions with respect to the center, but is formed in a rounded shape as in the previous embodiment. Even if the module 100 is formed in a rounded form, the effects are the same.

As such, the technical spirits described in the embodiments of the present invention may be independently implemented, or may be implemented in combination with each other. In addition, the present invention has been described through the embodiments described in the drawings and the detailed description of the invention, which is merely exemplary, and those skilled in the art to which the present invention pertains have various modifications and equivalent other embodiments.
