Description

{RENEWABLE ENERGY AIR HANDLING UNIT}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a new and improved air conditioner, and more particularly, to a new and renewable air conditioner capable of exchanging heat between air to be discharged by operation of a heat exchange unit and air to be introduced.

In general, an air conditioner refers to a device used to adjust a certain space to a temperature, humidity, airflow distribution suitable for a person to operate, and to remove dust and the like in the air at the same time.

Usually, the room temperature that a person feels comfortable is sensible, so it may be different depending on the person. However, in summer, the outside temperature and the temperature difference are about 5 to 6 ° C, the room temperature is 25 to 29 ° C and the humidity is 60 to 70% , And in winter, it is known that the room temperature is about 18 to 21 ° C and the humidity is about 55 to 70%. At this time, the principle of controlling the temperature in the air conditioner is the evaporation heat which takes heat away from the surroundings when the liquid evaporates as in a refrigerator or a refrigerator.

These types of air conditioners range from compacts used in the home to those used in buildings. Large-sized special-type air conditioners have a central unit in the center, where ducts are used to cool and heat each room. The centralized system is centralized.

That is, the air (RA) in the room is sucked through the ventilator and then exhausted to the outside, and the outside air (OA) is sucked and passed through the filter to filter the foreign substances. Or heated and then supplied to the room. However, the existing air conditioner discharges the heated air in the room and heats the external cold air, resulting in a lot of energy loss.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The embodiments of the present invention can be modified in various forms, and the scope of the present invention should not be construed as being limited to the embodiments described below. The embodiments are provided to explain the present invention to a person having ordinary skill in the art to which the present invention belongs. Accordingly, the shape of each element shown in the drawings may be exaggerated to emphasize a clearer description.

FIG. 1 is a front cross-sectional view schematically showing a fresh and renewable air conditioner according to an embodiment of the present invention, and FIG. 2 is a plan sectional view schematically showing a fresh and air-conditioned air conditioner according to an embodiment of the present invention. As shown in Figs. 1 and 2, the renewable air conditioner includes an enclosure 100. Fig. The ventilation opening 120 and the air supply opening 140 are formed on both sides of the upper portion of the enclosure 100 and the auxiliary exhaust opening 136 and the auxiliary exterior opening 138 are formed on the upper center side of the enclosure 100, And an air supply mechanism 140. [ The shutters 136a and 138a can open and close the auxiliary vent 136 and the auxiliary external mechanism 138, respectively.

The housing 100 has an inner space, and the inner space is partitioned by the first and second partition walls 133 and 135. The first partition 133 is provided between the vent 120 and the auxiliary vent 136 and divides the internal space into an intake space 132 and an air supply space 134. The intake space 132 communicates with the vent hole 120. The second partition 135 is provided between the auxiliary exhaust 136 and the auxiliary external mechanism 138 and divides the air supply space 134 into a first air supply space 134a and a second air supply space 134b and 134c . The first air supply space 134a communicates with the auxiliary exhaust port 136. [ The filter 150 and the coil 160 are installed between the auxiliary external mechanism 138 and the air supply mechanism 140 and the second air supply spaces 134b and 134c are connected to the second air supply space 134b and the second air supply space 134b, Space 134c. The second front air supply space 134b communicates with the auxiliary outer mechanism 138 and the second rear air supply space 134c communicates with the air supply mechanism 140. [ Unlike the present embodiment, the positions of the filter 150 and the coil 160 can be changed from each other.

The suction fan 122 is installed in the intake space 132 and the discharge port of the suction fan 122 is connected to the communication port 130a formed in the first partition 133. [ The air supply fan 142 is installed in the second rear air supply space 134c and the discharge port of the air supply fan 142 is installed in the air supply mechanism 140. The ventilation air flows into the intake space 132 through the ventilation opening 120 and the outside air introduced into the interior space of the enclosure 100 is guided by the air supply mechanism 140 during operation of the air supply fan 142. [ To the room. The filter 150 filters the outside air flowing into the inner space of the housing 100, and the outside air can be cooled or heated through the coil 160, and then supplied to the room.

The damper 139 is installed on the communication hole 130b formed in the second partition 135 and the ventilation flow in the first air supply space 134a is controlled by adjusting the opening of the communication hole 130b to the second front air supply space 134b. That is, 30% of the ventilation flow introduced through the ventilation opening 120 can be discharged through the exhaust opening 152 to be described later, and 70% can be passed through the damper 139 to the second front supply space 134b, By introducing the outside air through the external mechanism 154 by 30% discharged, the amount of final air supplied through the air supply mechanism 140 can be maintained at 100% by adding 70% passing through the damper 139 and 30% outside air.

2, the exhaust port 152 and the external mechanism 154 are formed on the side wall of the housing 100 to which the first and second partition walls 133 and 135 are connected, and the second partition wall 135 Are placed on both sides as a reference. The heat exchange unit 180 is installed outside the exhaust port 152 and the external mechanism 154. The ventilation flow discharged through the exhaust port 152 and the outside air introduced through the external mechanism 154 are supplied to the heat exchange unit 180 ). Therefore, when the temperature of the ventilating flow is higher than the temperature of the outside air, the temperature of the ventilating flow falls and the temperature of the outside air rises. When the temperature of the ventilating flow is lower than the temperature of the outside air, Lt; / RTI >

As described above, when the heat exchanging unit 180 is disposed on the side wall of the housing 100, the height of the housing 100 can be greatly reduced. That is, when the heat exchanging unit 180 is installed, the supporting frame and the extending duct described later take up a considerable volume, and when the heat exchanging unit 180 is located on the upper wall of the housing 100, do. Therefore, when the height of the installation space is relatively low, such as an underground space, installation is limited. On the other hand, since the underground space is an idle space and has a large area, if the heat exchange unit 180 is installed on the side wall of the enclosure 100, the underground space can be installed without restriction as above.

As described above, in the conventional air conditioner, the ventilation flow is simply discharged through the vent corresponding to the auxiliary vent 136 in Fig. 1, and the outside air is passed through an external mechanism corresponding to the auxiliary external mechanism 138 in Fig. 1 The energy is not transferred between the ventilation flow and the outside air, resulting in energy loss. In such a conventional air conditioner, a separate exhaust port and an external mechanism are formed on the side wall of the enclosure of the air conditioner, the heat exchanging unit is installed on the exhaust port and the external mechanism, and the existing exhaust port and the external device are opened and closed through the shutter, The air conditioner can be easily modified by the renewable air conditioner according to the present embodiment. That is, it is difficult to form separate exhaust ports and external mechanisms due to the existing exhaust port and the external mechanism in the upper portion of the housing, and the exhaust pipe and the external engine to be described later are installed on the upper portion of the enclosure, Since the side space (particularly, the rear side) has a sufficient spatial margin, energy efficiency can be greatly improved by retrofitting a conventional air conditioner by applying the structure of the above-described embodiment.

The extension duct 192 extends outward from the side wall of the housing 100 and is disposed around the exhaust port 152 and the external mechanism 154. The extension duct 192 has an accommodating space 194 adjacent to the exhaust port 152 and the external mechanism 154 and a support frame to be described later is installed in the accommodating space 194. The accommodation space 194 communicates with the exhaust port 152 and the external mechanism 154. The extension duct 192 has an extended exhaust port 197 and an extended external mechanism 198 and the extended exhaust port 197 and the extended external mechanism 198 are partitioned by the separation wall 196. The extended exhaust port 197 and the extended external mechanism 198 are located outside the accommodation space 194 and communicate with the accommodation space 194.

The pressure gauges 210 and 220 may be installed in the first air supply space 134a and the second air supply space 134b and the controller 230 may be electrically connected to the pressure gauges 210 and 220. The pressure gauges 210 and 220 detect the pressures of the first supply space 134a and the second supply space 134b to convert them into electrical signals and transmit them to the controller 230. The controller 230 outputs signals The pressures of the first supply space 134a and the second supply space 134b can be measured.

The controller 230 sends an electrical signal to the alarm 240 when the measured pressure of the first supply air space 134a is higher than the reference pressure and the alarm 240 is an alarm (for example, a sound or a lamp) The replacement time of the heat exchange medium to be described later can be announced. As will be described later, the heat exchange medium is a porous material and can perform a filtering function by itself. Therefore, foreign matter may be adhered to the heat exchange medium during a certain period of time, and the ventilation flow can not smoothly pass through the heat exchange medium, thereby increasing the pressure in the first air supply space 134a. In this case, the pressure of the first supply space 134a may be higher than the reference pressure, and the controller 230 may determine the replacement timing of the heat exchange medium through the pressure change of the first supply space 134a. The controller 230 sends an electrical signal to the alarm 240 when the measured pressure of the second supply air space 134b is lower than the reference pressure and the alarm 240 is an alarm Lamp) can inform the replacement time of the heat exchange medium described later. The pressure of the second supply space 134b may be lowered to a level higher than the reference pressure by an increase in the pressure drop due to foreign substances in the heat exchange medium.

The pressure gauges 210 and 220 may be installed in the exhaust port 152 or the external mechanism 154 communicating with the first and second air supply spaces 134a and 134b and a separate standard pressure gauge may be installed on the pressure gauge (E.g., the receiving space 194, the auxiliary exhaust port 197, and the auxiliary external mechanism 198). The reference pressure described above can be set based on the pressure measured through the reference pressure gauge and the replacement timing of the heat exchange medium can be determined based on the difference between the reference pressure and the measured pressure.

Fig. 3 is a perspective view schematically showing the support frame shown in Fig. 1, and Fig. 4 is a photograph showing an example of a heat exchange medium mounted on the support frame of Fig. The heat exchange unit 180 has a support frame and a heat exchange medium, and the support frame rotates in the accommodation space 194. The support frame is connected to a motor installed in the separation wall 196. 3, the support frame includes first and second support rings 184a, 184b spaced around the body 182 and the body 182, a body 182 extending radially from the body 182, Connecting bars 186 connecting the first and second supporting rings 184a and 184b and supporting bars 188 disposed in the spaces formed between the connecting bars 186, respectively.

The first support ring 184a may have a polygonal shape having the same number of corners as the number of the connection bars 186, and may be octagonal, as shown in Fig. The second support ring 184b may be in the form of a circular ring. The connection bars 186 may be positioned at the corners of the first support ring 184a and conformally disposed. The space is partitioned by the body 182, the first and second support rings 184a and 184b, and the connection bars 186, and the heat exchange medium shown in Fig. 4 is installed in the space. Support bars 188 may be installed in space to support heat exchange media and connection bars 186. As described below, the heat exchange media can be individually desorbed depending on the replacement cycle or degree of contamination, and the operator can easily clean the removed heat exchange medium or replace it with a new heat exchange medium.

As shown in FIG. 4, the heat exchange medium is divided according to the size and shape of each space, and can be easily replaced and used as needed. The heat exchange medium may be in the form of a random matrix and may be used by ceramic coating an interconnected heat retentive fibrous mat of filaments having a diameter of 25-150 microns. Ceramic coatings are intended to prevent heat-retention fibrous mats from causing fungus or propagating bacteria due to moisture. For example, the ceramic coating may be formed by grinding the pulverized charcoal powder into water to make an immersion liquid, and immersing the heat-retentive fibrous mat in the immersion liquid, and then drying it to be used as a heat exchange medium. Through such a method, the heat exchange medium can have an antibacterial and deodorizing function, and it is possible to eliminate the possibility of propagation of fungi and bacteria due to ventilation flow and outside air.

Further, since the heat exchange medium is made of a porous material, ventilation flow or outside air can pass through the heat exchange medium. Specifically, the heat exchange medium (in particular, heat retention fibrous mat) may be a polyester filament having a specific gravity of 1.38, a thermal conductivity of 0.16 watts / m · K, and a specific heat of 1,340 J / kg · K. Particularly, since the heat exchange medium is a porous material, it can perform the filtering action by itself. Therefore, foreign matter may be adhered to the heat exchange medium during long-term use, thereby increasing the pressure drop of the ventilation flow and the outside air passing through the heat exchange medium. In this case, the operator can individually detach the heat exchange medium and easily maintain it. A separate passage (not shown) is formed on the side surface of the extension duct 192, and the passage communicates with the accommodation space 194. The operator can open and close the passageway opening and closing door, access the inside of the receiving space 194 through the passage, check the condition of the heat exchange medium, or remove or replace the heat exchange medium by washing or replacing.

Meanwhile, unlike the above-described heat exchange medium, a plurality of heat exchange fins are fixed on a support frame of a honeycomb type heat exchange medium made of an aluminum material. Accordingly, there is a disadvantage that the ventilation flow and the outside air exchange energy through aluminum having excellent thermal conductivity, but it is inconvenient that the heat exchange medium can not be desorbed or cleaned during long-term use, and aluminum has a low specific heat compared to the thermal conductivity, have.

Figs. 5 to 8 are views showing a state in which the new-regenerated air conditioner shown in Figs. 1 and 2 operates. Hereinafter, the operation of the renewable air conditioner will be described with reference to FIGS. 5 to 8. FIG.

First, as shown in FIG. 5, when the intake fan 122 operates, the ventilating flow flows into the intake space 132 through the vent hole 120, and then flows into the first air supply space 134a. At this time, the shutters 136a and 138a are in a state in which the auxiliary exhaust port 136 and the auxiliary external mechanism 138 are closed, and the damper 139 is in a state in which the communication port 130b is closed. The ventilated air is introduced into the first air supply space 134a and then discharged to the outside through the vent 152 and the extended vent 197. The extended exhaust port 197 is connected to a separate exhaust pipe (not shown), and the ventilation flow is discharged through the exhaust pipe.

On the other hand, during operation of the air supply fan 142, the outside air flows into the second front air supply space 134b through the extension external mechanism 198 and the external mechanism 154, (Not shown), and the outside air flows through the external organs. At this time, the support frame and the heat exchange medium are rotated by the motor, and the ventilation flow and the ambient air pass the heat exchange medium and transmit sensible heat and latent heat energy to each other. For example, when the temperature of the ventilation flow is higher than the temperature of the outside air, the heat exchange medium absorbs energy from the ventilation flow passing through the heat exchange medium in a state where the heat exchange medium is disposed in the exhaust port 152 and the extended exhaust port 197, In the state in which the outside air is disposed in the outward mechanism 198 and the outside mechanism 154, the outside air passes through the heat exchange medium to absorb energy from the heat exchange medium. In this way, the energy is transferred and the waste heat energy of the ventilation flow can be recovered.

That is, when heating is required, the outside air can be preheated to a predetermined temperature through the ventilation flow, and when it is necessary to cool, the outside air can be cooled to a predetermined temperature through the ventilation flow. Therefore, energy required for heating or cooling the outside air can be reduced. Thereafter, the outside air may be filtered through the filter 150, further cooled or heated through the coil 160, and then supplied to the room through the air supply device 140.

On the other hand, as shown in Fig. 6, a part of the ventilation flow may be introduced into the second front air supply space 134b through the damper 139. [ That is, as shown in FIG. 5, 30% of the ventilation flow is discharged through the exhaust port 152 and 70% is discharged through the damper 139 to the second front side The amount of the final air to be supplied through the air supply mechanism 140 can be increased by 70% passing through the damper 139 and by the amount of air passing through the air supply space 134b, 30% can be combined to maintain 100%. The amount of the ventilation flow from the first air supply space 134a to the second front air supply space 134b can be adjusted through the damper 139. [

7, when the operation of the heat exchange unit 180 is stopped with the auxiliary exhaust port 136 and the auxiliary external mechanism 138 being opened through the shutters 136a and 138a, The air is introduced into the intake space 132 via the vent hole 120 and then discharged through the auxiliary exhaust port 136 through the first air supply space 134a and the outside air is supplied to the second front air supply space 134b and then flows into the room through the air supply mechanism 140 via the filter 150 and the coil 160. [ The auxiliary exhaust 136 is connected to the exhaust pipe (not shown) described above, and the ventilation flow is discharged through the exhaust pipe. The auxiliary external mechanism 138 is connected to the external engine (not shown) do.

That is, in the case of a seasonal change, the temperature of the room (ventilation flow) is high and the temperature of the outdoor (outdoor) is appropriately maintained at 17 to 18 DEG C, so that the ventilation flow and the outside air do not need heat exchange separately. Therefore, in such a case, the outside air can be introduced through the auxiliary external mechanism 138 while the operation of the heat exchange unit 180 is stopped, and then supplied to the room through the air supply mechanism 140.

As described above, since energy is transferred between the ventilation flow discharged through the heat exchange medium and the outside air introduced, the energy required for air conditioning can be reduced by recovering the waste heat energy generated when the ventilation flow is discharged, and more than 90% A high heat recovery rate can be secured. In particular, efficient air conditioning can be realized by adjusting the amount of ventilation flow and the amount of outdoor air introduced, if necessary.
