Description

Absorption humidifying simultaneous heating using waste heat of adsorptive rotary air conditioner}

The present invention relates to a humidification combined air-conditioning apparatus suitable for waste heat recovery type air-conditioning apparatus capable of achieving air conditioning in a residential place such as an office, a home, an officetel, or an industrial facility equipped with a manufacturing facility.

It is well known that air conditioning, especially cooling systems, rely heavily on Freon refrigerants. Freon refrigerants are known to react with and destroy ozone in the stratosphere, causing severe environmental damage. Its use is limited and there is an urgent need to replace it.

However, materials having comparable performance to freon gas have not yet been discovered or invented, and the development of them is in need of further development. Therefore, the use of the currently available freon gas has been increased to actively suppress its use.

As an example, paying attention to the fact that the cooling load discharged to the latent heat through moisture during cooling becomes 70% or more, the latent heat is recovered and recycled through the adsorption rotor and the sensible heat exchanger, thereby improving the cooling efficiency and waste of freon gas through it. There is a way to suppress the use of enemy.

Fig. 3 is a diagram showing the configuration of a cooling device employing the adsorption rotor and the sensible heat exchanger. The air conditioner duct 4 having an interior divided by the partition wall 2 has an exhaust passage 4a and an intake passage 4b. A proper location of these passages 4a and 4b is arranged so that the sensible heat exchange rotor 6 and the dehumidification rotor 8 can rotate across the passages 4a and 4b.

At the one end of the exhaust passage 4a, an outdoor damper 10 for introducing external air and an indoor damper 12 for introducing a part of the air discharged to the outside are arranged side by side to exhaust the indoor air. Is mixed with the external hot air to form a temperature-humidity equilibrium with each other, and then the mixed air is filtered through the exhaust filter 14 and then cooled through the vaporization cooling cell 16 before the sensible heat. It is discharged to the outside after passing through the exchange rotor (6)-summer heating coil (18)-dehumidification rotor (8). This exhaust action is caused by the action of the exhaust fan (20) provided in the exhaust passage (4a). It is to be done.

In addition, the outside air sucked through the intake passage (4b) is controlled by the amount of suction through the outdoor side damper 22, the air sucked in this way is passed through the rain-proof dust grill 24 and the air supply filter 26 Next, the dehumidification rotor (8) is sequentially contacted with the sensible heat exchange rotor (6), and is then supplied to the room via the summer sensible heat recooling coil (28) and the reheat coil (30). It is supposed to be done by action.

Since the sensible heat exchange rotor 6 and the dehumidification rotor 8 are rotationally driven at a constant speed by the sensible motor 34 and the dehumidification motor 36, the space between the exhaust passage a and the air supply passage 4b is limited. Is distributed. In addition, the sensible heat exchange rotor (6) and the dehumidification rotor (8) is a ceramic heat exchange medium having a honeycomb structure and has the same passage having a plurality of passages opened on the colgate along the axial direction so that the unit contact amount of air passing therethrough is large. The dehumidifying rotor 8 is different from the sensible heat exchange rotor 6 in that the dehumidifying rotor 8 is coated with an adsorbent on its surface to adsorb moisture. On the other hand, the summer sensible heat re-cooling coil (28), which is in contact with the air passing through the sensible heat exchange rotor (6) in the intake passage (4b) next to cool the air while the refrigerant is circulated, the refrigerant 휀 ( The cooling system by the cooling unit 46 consisting of a condenser coil 40 which is radiated by the 38, a refrigerant receiver 42 for separating and storing the condensed refrigerant, and a compressor 44 forcibly circulating and condensing the refrigerant. It is supposed to constitute.

The cooling device having such a configuration has a large energy saving effect of reducing the freezer operation time and the refrigerant consumption by about 50% since the sensible energy of the air exhausted for indoor ventilation is recovered and recycled.

However, the heating and humidification ventilation required for the season or winter should use a separate dedicated device, so in the environment with climatic conditions where four seasons are clearly distinguished, like in Korea, the cost of installing the cooling and heating facilities Becomes excessive. In addition, heating / humidification requires a separate dedicated facility as well as a pipe water supply facility. Therefore, the structure is complicated and the cost is high. Instead, the energy loss is excessive, and the saturated steam generated in the humidification process causes corrosion of the device. As a result, the service life is also short, and since it is unclean humidification, it is not satisfactory in terms of heating and humidification efficiency.

The rainproof dust grill 24 disposed at the inlet side of the intake passage 4b has a structure having a plurality of barrier plates 24a inclined in a straight line as shown in FIG. There are also disadvantages of not completely separating and removing rainwater and fuchsia. Also, if the filter is clogged by fine fleece during use, the operation must be stopped and replaced.

On the other hand, the present inventor has proposed a cold heater capable of parallel humidification through the Republic of Korea Utility Model Registration Application No. 2000-6642, the proposed configuration is only a level that can be applied to small-scale residential facilities.

Therefore, an object of the present invention is a waste heat recovery type cooling device equipped with a sensible heat exchange rotor and a dehumidification rotor, combined with a humidification suitable for waste heat recovery type cooling device having a new structure so as to maximize the cooling and heating efficiency regardless of the size of the scale In providing a heating and cooling device.

Another object of the present invention is to provide a humidifying combined air-conditioning apparatus suitable for waste heat recovery air-conditioning apparatus having a grill for completely removing and separating rainwater and dust from the outside air being sucked. In providing.

It is still another object of the present invention to provide a humidifying combined air-conditioning apparatus suitable for a waste heat recovery air-cooling apparatus, by adding a self-cleaning function to a filter for filtering out fine dust in the air passing through the grill, which can be operated without a long-term filter replacement. An object of the present invention is to provide a humidification combined air-conditioning apparatus suitable for a formula air-conditioning apparatus.

The present invention for realizing the above object is arranged on the front side of the sensible heat exchange rotor disposed between the exhaust passage and the intake passage arranged a copper cooling coil which is selectively connected to the normal cooling system by a three-phase valve, the dehumidification rotor in the intake passage At least one copper heating coil is disposed at the front end of the cooling unit, and a refrigerant system is formed between the inlet side and the compressor outlet side of the cooling unit as a bypass system leading to the copper heating coil and the same cooling coil. By inserting three-phase valves respectively at the inlet side and the compressor outlet side, the refrigerant of the refrigeration cycle is selected as a cooling system leading to the condenser coil and summer cooling coil of the cooling unit, or a bypass system leading to the same heating coil and the same cooling coil. It becomes the structure which made it possible to supply circularly.

In addition, the apparatus of the present invention includes a smooth "∨" shaped bent portion, and the rain-proof dust grill made of a barrier plate formed in a predetermined place is formed on the bottom surface corresponding to the bent to open the inlet side toward the inlet side It may be implemented in a configuration disposed on the inlet side of the intake passage.

In addition, the apparatus of the present invention has a configuration that can periodically clean the air supply filter by arranging a branch pipe body having a plurality of nozzles in which the compressed air is back sprayed to the rear surface of the air supply filter disposed on the rear end side of the rainproof dust grill. Can be implemented.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a configuration related to the apparatus of the present invention. Basically, the same parts as those shown in FIG. 4 are described with the same reference numerals in order to avoid duplication of description.

In a suitable place between the exhaust passage 4a and the intake passage 4b of the air conditioner duct 4 divided into partitions 2, the ordinary sensible heat exchange rotor 6 and the dehumidification rotor 8 rotate horizontally. The outdoor damper 10 and the indoor damper 12 arranged side by side at one end of the exhaust passage 4a are for controlling the amount of mixing of the introduced air and indoor air.

The cooling coil 48 for the winter season is positioned at the front end side of the sensible heat exchange rotor 6 after the exhaust side filter 14 and the vaporization cooling cell 16 which are sequentially arranged at the rear end side of both dampers 10 and 12. This opening is operated only during the winter season, and the temperature of the discharged air is lowered to promote the dehumidification effect.

The sensible heat exchange rotor 6 only performs heat exchange with the air passing therebetween, and does not perform adsorption removal of moisture, and operates only in summer.

The dehumidifying rotor 8 disposed at the rear end side of the sensible heat exchange rotor 6 performs a humidifying action in winter and a dehumidifying action in summer, with respect to the air flowing into the room as described below.

On the other hand, in the intake passage 4b, a winter heating coil 50 is disposed on the rear end side of the air supply filter 26, which serves to warm the outside air introduced from the outside during the winter season. The copper heating coil 50 may be arranged alone or in the same structure in plural, and FIG. 1 illustrates an example in which one pair is arranged in parallel.

In the intake passage 4b, the summer sensible heat recooling coil 28 is disposed in parallel with the winter cooling coil 48 at the rear end side of the sensible heat exchange rotor 6, and the reheat coil 30 and the rear end side thereof. The summer vaporization cooling cell 52 is arrange | positioned continuously.

Also in the apparatus of the present invention, a cooling unit 46 is provided separately from the air conditioner duct 4 having the above-described configuration, but the refrigerant circulation system by this is completely constituted. That is, the inlet side of the refrigerant receiver 42 and the outlet side of the compressor 44 are connected to the compressor 44-the condenser coil 40-the refrigerant receiver 42 to the summer sensible ash cooling coil 28. The cooling system 58 which allows the refrigerant to circulate, and the compressor 44-the copper heating coil 50-the refrigerant receiver 42-the copper cooling coil 48 circulates and returns to the compressor 44 again. A three-phase valve 62 is provided at the outlet side of the compressor 44 and the inlet side of the refrigerant receiver 42 to select the cooling system 58 and the bypass system 60. ) Is interposed.

The cooling action condensing and radiating the refrigerant condensed and radiated in the condenser coil 40 of the cooling unit 46 by the above-described structure is evaporated and absorbed in the summer sensible ash cooling coil 28, and evaporated in the winter cooling coil 48. It is to be able to selectively use the heating action to repeat the process of heat absorption and condensation heat dissipation in the copper heating coil (50).

The device of the present invention having the characteristic configuration as described above is used to be divided into the season / winter heating mode and the summer cooling mode, which will be described in detail as follows.

(Summer cooling mode)

Indoor cooling in the summer is switched to the cooling unit 46 side so that the refrigerant is not supplied to the winter heating coil 50 through both three-phase valves 54 and 56, and another three-phase valve 62 is The refrigerant is not switched to the cooling coil 48 side, and the sensible heat exchange rotor 6 and the dehumidification rotor 8 are rotated at a constant speed.

The air drawn into the exhaust passage 4a through the indoor damper 12 during operation passes through the vaporization cooling cell 16 while forming an equilibrium of the wet bulb where some external air through the outdoor damper 10 is mixed. It is vaporized and cooled to wet-bulb temperature by the cooling water circulated and sprayed here. The air cooled by passing through the vaporization cooling cell 16 passes while cooling it through a heat exchange action in the sensible heat exchange rotor 6, and is then exhausted through the summer heating coil 18 and the dehumidification rotor 8.

The summer heating coil 18 reheats the exhaust gas passing through the sensible heat exchange rotor 6, whereby the heated exhaust air is dried while absorbing moisture while being in contact with the subsequent dehumidification rotor 8.

On the other hand, the outside air sucked through the intake passage (4b) is controlled by the outdoor damper 22 and the suction amount is passed through the rainproof dust grill 24 and the air supply filter 26, and then the dehumidification rotor (8) and In this case, since the dehumidification rotor 8 is dried through contact with the exhaust air, the dehumidification rotor 8 is converted into dry air from which latent heat is removed by absorbing moisture from outside air sucked into the dehumidification rotor 8.

When the outside air dried through the dehumidification rotor 8 passes through the sensible heat exchange rotor 6 again, it exhibits a cooling action of the adsorption rotor method in which sensible cooling is performed by heat exchange.

On the other hand, when the summer sensible heat re-cooling coil 28 and the summer vaporization cooling cell 52 disposed on the rear end side of the sensible heat exchange rotor 6 have an indoor cooling effect due to the sensible heat action and the generated sensible heat is excessively generated. Minimal use is to ensure proper cooling.

(Winter season / Winter heating mode)

In winter, the three-phase valves 54 and 56 are switched so that the refrigerant is supplied to the winter heating coil 50 to block the condenser coil 40 side of the cooling unit 46, and at the same time, a separate three-phase valve ( 62) dehumidifies while switching the refrigerant from being supplied to the summer sensible ash cooling coil 28 and at the same time stopping the sensible heat exchange rotor 6, the summer heating coil 18, and the summer vaporization cooling cell 52. Indoor heating is performed while only the rotor 8 is operated.

During indoor heating, the refrigerant does not go to the condenser coil 40 of the cooling unit 46 but is sent to the winter heating coil 50 through the three-phase valve 56 at the outlet side of the compressor 44 to condense and radiate again. It passes through the upper valve 54 to the refrigerant receiver 42-the same type of cooling coil 48 to form a circulation system for evaporative endotherm.

Accordingly, the air exhausted through the exhaust passage 4b is cooled down while passing through the same type of cooling coil 48, and then cooled, and then passed through the dehumidification rotor 8, and the moisture contained therein is adsorbed and removed to be discharged to the outside.

At this time, the exhaust cooling action through the winter cooling coil 48 allows the moisture contained in the exhaust to be adsorbed and removed from the dehumidifying rotor 8 with high efficiency and stabilizes the low pressure pressure of the refrigeration cycle. Condensation heat dissipation (waste heat) appearing in the heating coil 50 is performed stably.

And the outside air heated by passing through the winter heating coil 50 in the intake passage (4a) passes through the dehumidification rotor (8) is given moisture absorbed from the exhaust is converted into humidified air.

The humidified and warmed outside air passes through the sensible heat exchange rotor (6) and the summer sensible heat re-cooling coil (28) as they are, and is supplied to the room to be heated, and in this process, the reheat coil (30). ) Can be heated to improve the heating efficiency.

The switching operation of the three-phase valves 54, 56 and 62, which enables the selective circulation of the refrigerant in the cooling operation as described above, can be easily implemented by employing a general controller widely used in this field. .

In particular, the apparatus of the present invention utilizes the waste heat generated by condensing the refrigerant of the cooling cycle in the winter heating coil 50 to heat the outside air as described above, and the process of recovering the humidifying action from the indoor air through the dehumidification rotor 8. Since the heating operation using the waste heat is not impeded, the high efficiency heating is realized, and economical efficiency is ensured. Also, the cooling unit 46 is continuously operated over four seasons instead of seasonal intermittent operation. Stable operation is also possible.

On the other hand, in the apparatus of the present invention, the cross-sectional structure of the rainproof dust-proof grill 24 is formed of a barrier plate 24a having a smooth “b” -shaped bent portion 24b, as shown in Fig. 2, and the barrier plate 24a. The bottom portion of the bent portion 24b and the portion corresponding to the bent portion 24b are formed with a capture 24c opened toward the inlet side, and at the same time a small capture 24d can be adopted.

The structure as described above is a downward and upward flow when the air being sucked passes the rainproof dust grill 24, the dust, particles, rain water, etc. contained in this process is filtered by the capture 24c (24d) By preventing it exhibits excellent dustproof action.

In addition, the outlet side of the air supply filter 26, which is provided on the rear end side of the rainproof dust grill 24, is provided with a branch pipe body 26a capable of injecting compressed air through a plurality of nozzles as shown in FIG. As the compressed air is jetted, fine dust and the like deposited on the inlet side can be self-cleaned so that the air supply filter 26 is blocked so that the efficiency is not lowered.

As described above, the present invention divides the flow of the refrigerant circulating in the cooling unit in the conventional adsorption rotor type air conditioning system into a general cooling system and a separate bypass system, and is generated through a winter heating coil in the bypass system. Humidification and heating required during the summer and winter seasons through simple constitution that utilizes condensation heat dissipation for heating and cools down the indoor exhaust when the condensed refrigerant is evaporated and absorbed in the winter cooling coil. Because it combines all the required cooling, compared to the conventional adsorption rotor method, it is possible to cool and heat without having a separate humidifier and heating device, and thus the cost of cooling and heating equipment is minimized. Deterioration of equipment due to continuous use of cooling units in winter without interruption Economic effects of delay and efficient use can be obtained.

In addition, another embodiment of the present invention has an excellent dustproof effect has the effect of preventing the occurrence of equipment failure in advance, in particular, the cleaning of the filter by the back spray is a self-cleaning effect that can omit periodic inspection of the equipment As a result, management costs are reduced.
