Description

[0001] SELF CLEANING TYPE TOTAL HEAT EXCHANGE SYSTEM [0002]

One embodiment of the present invention relates to an overall heat exchange system formed so as to be able to clean the inside of a heat exchanger.

BACKGROUND ART [0002] Generally, an air conditioner such as a thermo-hygrostat or an air purifier including an air conditioner circulates indoor air of a building and sucks it together with air sucked from the outside to remove various foreign substances and contaminants, So that a pleasant life can be achieved.

Such an air conditioner is essentially provided with an air filter for filtering various foreign substances including dust contained in the air sucked from the outside and supplying clean air to the room.

In case of such an air filter, the performance of the air conditioner should be maintained, but the filter must be prevented from being damaged or cleaned or cleaned.

However, in recent years, in order to protect the human body from air pollution factors caused by frequent occurrence of yellow dust, automobile exhaust gas, scattered dust of the construction site, and to maintain the air quality of the residential space and the production site at the required level, The cost of replacing and managing filters is rapidly increasing.

The air purifier for purifying indoor air can be broadly divided into a dry air purifier and a wet air purifier.

In the case of the dry air purifier, the air filter developed in various structures is installed in the purifier on the air flow path, and the dust contained in the air is collected by the air filter. However, in such a dry air purifier, The efficiency of filtering contaminants is reduced, and the air pressure of the blower is increased due to contaminants accumulated in the air filter, and the air volume of the air is decreased.

In addition, as the air flow rate decreases, the temperature and humidity of the room change, so the room temperature and humidity must be maintained by cooling and heating. Therefore, not only the energy usage is increased but also the manager takes over the air filter And there is a problem that the air filter must be replaced.

Meanwhile, the wet air purifier proposed as a method for solving the above problem is capable of purifying the air by removing the pollutants in the air as liquid and collecting the liquid. The wet cleaning method of the cleaning type air purifier is generally So that the pollutants of the fine particles contained in the air can be separated and adsorbed.

However, since such a wet air purifier utilizes the existing dry equipment as it is, it circulates air before and after the air passes through the air filter, and then spray water to filter contaminants in the air together with the air filter Most pollutants in the air are filtered by the filter, so that the filter must be frequently exchanged or cleaned, and the maintenance thereof must be continued.

Since the devices for cleaning the filter of the air cleaner described above are difficult to apply to the total heat exchange system, a more improved method that can be used for the device cleaning the inside of the heat exchange unit of the total heat exchange system can be considered.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an entire heat exchanging system which is formed so as to be able to clean the inside of a heat exchanger in a different manner from the existing one.

Another object of the present invention is to provide a total heat exchange system having a more advanced structure and having a complex function.

According to an aspect of the present invention, there is provided an overall heat exchange system comprising: a duct having a suction passage and a discharge passage; And a heat exchanger disposed in the duct, the heat exchanger being rotatably provided with a plurality of through holes, the heat exchanger including a first region communicating with the suction passage and a second region communicating with the discharge passage, In order to prevent contaminants from accumulating inside the through-holes, the nozzle portion and the suction portion are respectively disposed with the heat exchanger interposed therebetween.

According to an embodiment of the present invention, when air introduced from one side of the heat exchanger through the heat exchanger moves to the other side along the suction passage, a part of the air that has flowed along the discharge passage from the other side flows through the heat exchange Sectional area of the suction passage is formed to be smaller than a sectional area of the discharge passage to prevent the suction passage from moving to the suction passage due to rotation of the body.

According to an embodiment of the present invention, the suction portion is formed in the third region, and the nozzle portion may be formed in a position facing the suction portion.

According to an example of the present invention, the first sensor unit and the second sensor unit may be disposed with the heat exchanger interposed therebetween in order to measure the pressure difference, the temperature difference, or the humidity difference on both sides of the heat exchanger.

According to an example of the present invention, the first and second sensor portions may be disposed in the first region.

According to an embodiment of the present invention, the controller may further include a controller for controlling the operation of the nozzle unit or the suction unit based on the measurement results of the sensor units.

According to an embodiment of the present invention, the apparatus further includes a third sensor unit for sensing the movement of the heat exchanger, and the nozzle unit or the suction unit may operate only when the heat exchanger is rotated.

The total heat exchange system according to at least one embodiment of the present invention configured as described above can prevent a part of the contaminated air to be discharged from the room to the outside from entering the room again.

In addition, the performance of the heat exchanger can be maintained at the best condition at all times, and the service life of the equipment can be maintained, and the air quality ultimately supplied to the room as the outside air can be improved.

Then, the heat exchanger having the honeycomb matrix structure can be always cleaned.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an overall heat exchange system according to the present invention will be described in detail with reference to the drawings. The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

In order to prevent the inflow of air pollutants and to efficiently operate the air-conditioning inside the building, recently installed buildings have an air-conditioning system which mechanically circulates the inside air by eliminating the window in which the outside air directly flows. However, there is a problem in that the air becomes turbid only by circulating the inside air, and some of the outside air is introduced into the building. However, even in such a case, there is a problem that the indoor air and the outside air are mixed to continuously accumulate the indoor pollutants.

In addition, when outside air is introduced into a building, the sensible heat and latent heat load of the heating / heating equipment also increases simultaneously. As a result, there is a problem that the maintenance cost of the building is increased because the cooling / heating unit needs to be further operated and power is consumed to further operate the cooling / heating unit.

As the demand for indoor air quality improvement and energy saving is gradually increased, there is an increasing interest in the total heat exchange system as an alternative to achieve the above-mentioned two purposes at the same time. As an example of such an electric heat exchange system, there is a device for recovering the enthalpy (temperature and humidity) at the same time by discharging the indoor air that has been cooled and heated at an appropriate temperature and humidity, And a total heat exchanger (ROTARY ENTHANLPHY HEAT EXCHAGER). The rotary type total heat exchanger may be disposed inside the air conditioner or installed in a duct. The rotary type total enthalpy heat exchanger is composed of a honeycomb matrix in which the structure of the total enthalpy heat exchanger element is minute, and the air discharged from the room is heat exchanged with the outside air while being contaminated with fine dust and various chemical substances. Or the air filtering filter is provided in the outside air inlet of the duct, it is insufficient to prevent the contamination of the honeycomb matrix from being stacked with only the air filtering basic filter. Particularly, due to the clogging phenomenon of the honeycomb matrix, the pressure loss of the total enthalpy heat exchanger may be increased and the efficiency may be lowered. Therefore, the total heat exchanger system described below can be considered.

1 is a diagram showing the configuration of an total heat-exchanging system 100 according to an embodiment of the present invention.

The total heat-exchanging system 100 of the present invention is a device for recovering cooling and heating energy by exchanging heat between the outside air (inlet air, SUPPLY air) flowing in from the outside in case of cooling and heating and ventilation (RETURN AIR, EXHAUST AIR) That is, it is a device for recovering sensible heat and latent heat by using a difference in temperature and humidity between the outside air and the ventilation while rotating the heat exchanger 113 (see Fig. 4) at 2 to 20 rpm at low speed. To this end, the heat exchanger 113 is made of aluminum as a base material, and sensible heat is recovered by the heat transfer characteristic of aluminum. Then, aluminum is impregnated with a desiccant, and latent heat is recovered by the principle of adsorption of water vapor.

Referring to FIG. 1, the total heat exchange system 100 includes a heat exchanger module 110 and a duct 150.

The heat exchanger module 110 may be integrally provided with a nozzle unit 120 (see FIG. 4) and a suction unit 130 (see FIG. 4), which will be described later. The heat exchanger 113 is formed in the shape of a cylindrical body, and the inside thereof is formed in a honeycomb structure so that air can pass through the inside thereof.

Each of the ducts 150 has a suction passage 151 and a discharge passage 152. The suction passage 151 and the discharge passage 152 are partitioned from each other by a partition wall. The bulkhead may be implemented in the form of a partition and a seal. In order to distinguish them from each other, a partition disposed at one side with respect to the heat exchanger 113 is referred to as a first partition 111 (see FIG. 4), and a partition disposed at the other side is referred to as a second partition 112 . A suction fan 154 may be disposed in the suction passage 151 and a discharge fan 155 may be disposed in the discharge passage 152. In addition, the discharge passage 152 may be provided with a regeneration heater 157 which heats the introduced air to reduce the humidity and discharges the heat to increase the heat exchange efficiency of the heat exchange body 113. The duct 150 may be formed in the form of a housing of the air conditioner.

A heat pump device is disposed in the suction passage 151 to control the temperature of the air flowing into the room. The heat pump device 160 may include a compressor 161, four sides 162, first and second heat exchangers 163 and 164, and an expansion device 165. At this time, the first heat exchanger 163 is installed on the air discharge side of the heat exchanger module 110 in the discharge passage 152. The compressor 161, the four sides 162, the expansion device 165 and the second heat exchanger 164 are installed outside the duct 150 or in the discharge passage 152. When the above components are installed outside the duct 150, a fan 164a is installed near the second heat exchanger. Accordingly, the first heat exchanger 163 can heat and cool the indoor space to a predetermined temperature by discharging the heat exchanged outdoor air from the heat exchanger module 110 to the indoor space after heat-exchanging.

2 and 3 are views of a heat exchanger 113 according to an embodiment of the present invention, respectively.

Fig. 2 shows the principle of recovering sensible heat, and Fig. 3 shows the principle of recovering latent heat. As shown in FIG. 2, when the heat exchanger 113 rotates when the temperature difference is generated, heat is absorbed at a high temperature by the heat transfer characteristic of the aluminum base material, and heat is transferred to the low temperature to recover sensible heat by the temperature difference during cooling and heating. As shown in FIG. 3, when the humidity difference is generated, the desiccant impregnated in the heat exchanger 113 condenses moisture in the humid air through the adsorption and evaporates to the dry air. As a latent heat generated at this time, heat exchange is performed together with humidification and dehumidification.

4 is a conceptual diagram of the total heat exchange system 100 according to an embodiment of the present invention.

Referring to FIG. 4, the total heat exchange system 100 includes a duct 150, a heat exchanger 113, a nozzle unit 120, and a suction unit 130.

The duct 150 has a suction passage 151 and a discharge passage 152 with partition walls 111 and 112 interposed therebetween.

The heat exchanger 113 is disposed in the duct 150 and has a plurality of through holes to allow air to pass therethrough. The first region and the second region are formed on one surface and the other surface of the heat exchanger 113. The first region is an area communicating with the suction passage 151 and the second region is a region communicating with the discharge passage 152. [ to be.

Since the honeycomb-shaped heat exchanger 113 has a narrow internal passage, the passage may be narrowed or clogged when foreign substances are introduced into the passage. In this case, the efficiency of the heat exchanger 113 is lowered, and normal operation of the heat exchanger 113 becomes difficult.

In order to prevent this, the nozzle unit 120 and the suction unit 130 may be disposed with the heat exchanger 113 interposed therebetween.

The nozzle unit 120 may have a plurality of nozzles or may be disposed on one side of the heat exchanger 113 while one nozzle is arranged to be reciprocally movable. The nozzle unit 120 is formed so as to jet soft seawater, compressed water, or high-pressure gas (gas may include air, for example) toward the heat exchanger 113. In this way, the nozzle unit 120 can remove foreign matter inside by spraying soft seawater, compressed water, or high-pressure gas toward the heat exchanger 113.

The suction unit 130 is disposed on the other side of the heat exchanger 113 by forming the inside of the suction unit 130 in a low pressure state close to a vacuum. Therefore, it is possible to prevent the soft noble material, compressed water, or high-pressure gas discharged through the nozzle unit 120 from flowing into the room. Further, the foreign substances accumulated in the heat exchanger 113 are also sucked through the suction unit 130.

The operation of the nozzle unit 120 and the suction unit 130 can be controlled by a control unit (not shown). The control unit may be formed in the form of a microcomputer. Through the operation of the control unit, it can be sequentially sprayed through the nozzle unit 120 from any of the soft detergent, compressed water, and high-pressure gas. For example, it is possible to primarily remove the foreign substances in the heat exchanger 113 by spraying the soft water and the compressed water, and to remove the internal moisture by injecting the secondarily high pressure gas. Or only compressed air can be injected to remove or inhale foreign substances such as dust.

The first sensor unit 141 and the second sensor unit 142 may be disposed with the heat exchanger 113 interposed therebetween in order to measure the pressure difference, the temperature difference, or the humidity difference on both sides of the heat exchanger 113. The control unit controls the operation of the nozzle unit 120 or the suction unit 130 based on the measurement results of the sensor units. For example, when a pressure difference occurs on both sides of the heat exchanger 113 at a specific position, the controller determines that the inside of the air passage is clogged or narrowed, and can instruct the operation of the nozzle unit 120. The control unit can remove any foreign matter in the heat exchanger 113 by operating any one of the nozzles or moving the nozzle to the corresponding position.

The first sensor unit 141 and the second sensor unit 142 may be disposed in the first area.

In addition, a third sensor unit 143 for sensing the movement of the heat exchanger 113 may be disposed. The control unit can determine the rotational movement of the heat exchanger 113 through the third sensor unit 143 and thereby control the operation of the nozzle unit 120 or the suction unit 130. [ For example, the control unit may operate the nozzle unit 120 or the suction unit 130 only when the heat exchanger 113 rotates.

5 is a conceptual diagram of the total heat exchange system 100 according to another embodiment of the present invention.

Referring to FIG. 5, the total heat exchange system 100 includes a duct 150, a heat exchanger 113, a nozzle unit 120, and a suction unit 130.

The duct 150 has a suction passage 151 and a discharge passage 152 with a partition wall therebetween.

The heat exchanger 113 is disposed in the duct 150 and has a plurality of through holes to allow air to pass therethrough. The first region and the second region are formed on one surface and the other surface of the heat exchanger 113. The first region is an area communicating with the suction passage 151 and the second region is a region communicating with the discharge passage 152. [ to be. And a third region is formed on the other surface of the heat exchanger 113. The third region is a region where part of the air that has flowed along the discharge passage 152 from the other side when the air introduced from one side of the heat exchange body 113 moves to the other side along the suction passage 151 with the boundary of the heat exchange body 113 Sectional area of the suction passage 151 is formed smaller than the sectional area of the discharge passage 152 to prevent the suction passage 151 from moving to the suction passage 151 due to the rotation of the heat exchanger 113. [ That is, the third region is an area where the second bank is shifted more toward the first region. By forming the third region, it is possible to reduce the amount of air that is ventilated through the discharge passage 152 through the suction passage 151.

As described above, the nozzle unit 120 and the suction unit 130 may be disposed with the heat exchanger 113 interposed therebetween. At this time, the suction part 130 is formed in the third area, and the nozzle part 120 may be formed at a position facing the suction part 130. [ Thus, it is possible to prevent foreign matter from being re-introduced through the suction passage 151. [

The nozzle unit 120 may have a plurality of nozzles or may be disposed on one side of the heat exchanger 113 while one nozzle is arranged to be reciprocally movable. The nozzle unit 120 is formed so as to inject soft water, compressed water, or high-pressure gas toward the heat exchanger 113. In this way, the nozzle unit 120 can remove foreign matter inside by spraying soft seawater, compressed water, or high-pressure gas toward the heat exchanger 113.

Referring to FIG. 6, the suction portion 131 of the total heat exchange system may be arranged to cover the third region.

7, the suction unit 131 of the total heat exchange system may be disposed at a lower portion of the nozzle unit 120. As shown in FIG. That is, the nozzle unit 120 may be disposed above the first partition wall, and the suction unit 131 may be disposed below the first partition wall.

The reference numerals which are not described in FIGS. 6 and 7 will be referred to as the description described in FIG. 1 to FIG.

It is to be understood that the above-described total heat exchange system may be applied to a configuration and a method of the embodiments described above in a limited manner, but the embodiments may be modified such that all or some of the embodiments are selectively combined .
