Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-phase power generation system including a dehumidification cooling apparatus, a dehumidification cooling apparatus,

The present invention relates to a three-phase power generation system including a dehumidification cooling apparatus, a dehumidification cooling apparatus capable of dehumidifying cooling, heating, and electric power production, and a method of operating the same.

Distributed generation, which has become a recent issue, is a power generation system that distributes small power generation sources around power demand sites unlike existing large-scale centralized power generation. Centralized power generation is a method of supplying electricity generated by large-scale power plants, for example, nuclear power plants, to homes or buildings through a nationwide transmission perspective. Distributed power generation, on the other hand, is a method of generating electric power by building electricity generation facilities at the factory or building level.

Distributed generation has several advantages over centralized generation. First, the distributed power generation facility is located near the electricity demand site, so that the construction cost of the transmission and distribution infrastructure required for supplying the generated electricity to the demand site and the operating cost are reduced. In the case of the centralized power generation, the power loss is significant due to the reactive power generated in the transmission and distribution process, while the distributed power generation has an advantage that the power loss hardly occurs.

Second, distributed power generation does not require large-scale power plants and transmission / distribution infrastructure, so infrastructure construction costs are reduced, complaints do not arise, and site selection is less difficult. For example, nuclear power plants and hydroelectric power plants may face difficulties in selecting a candidate for a power plant due to environmental conditions and opposition from residents, and there may be environmental pollution concerns. However, distributed generation is free from these problems.

Third, distributed generation can increase the reliability of the power system. Since centralized power generation supplies electricity through the transmission forecast, if the entire power demand and supply imbalance occurs within the transmission forecast, the entire grid will collapse, resulting in a wide-scale power outage. However, even if there is an imbalance between electricity demand and supply, distributed generation will collapse only the grid in the building or area in question, so the damage can be recovered quickly and quickly.

Fourth, distributed power generation can produce power, cooling and heating energy using fuel such as engine or turbine, that is, only one energy source, and can recover and utilize the waste heat, which is advantageous in that it is energy efficient and environmentally friendly.

A typical example of distributed generation is a cogeneration system. The cogeneration system generates electric power by driving the generator with the power produced by burning the fuel in the engine. At this time, the heat energy that can be obtained from the exhaust gas or the cooling water of the engine can be recovered as a heat exchanger and used for cooling and heating.

In this way, a system capable of producing electricity and simultaneously cooling and heating is referred to as a tri-generation system. The triple power generation system can utilize the waste heat generated incidentally in the power generation process, and the efficiency of energy utilization is greatly improved, and the spread of the power is promoted in various countries around the world. As a result, it is analyzed that it contributes not only to energy saving but also to reduction of greenhouse gas emissions. Therefore, the triple power generation system is expected to be one of the energy systems that can effectively cope with global climate change.

A conventional triple power generation system is shown in Fig. Referring to FIG. 1, the engine 10 generates power by receiving fuel and supplies power to the generator 11 to generate electric power. Some of the fuel energy supplied to the engine 10 is converted to power and electric power and the remainder is in the form of heat energy such as exhaust gas or cooling water discharged from the engine 10. [

On the other hand, the pattern of energy demand for energy demand is very diverse. For example, there is a constant change in the demand and demand of the air-conditioner and electric power according to the use of the office, the hotel, the hospital, and the season, and the scale of the demand for the energy varies. In particular, the summer air temperature in the summer has been rapidly rising due to the high temperature and humidity, and the demand for cooling in the summer has been demanded.

In the conventional triple power generation system, as shown in FIG. 1, heat energy is recovered from waste heat discharged from the engine 10 and is sent to the absorption type cold / hot water generating machine 30. In the absorption type cold / hot water machine 30, 20 generates cold water or hot water by using the heat energy obtained from the waste heat of the engine 10 and utilizes it for cooling and heating.

The absorption type cold / hot water heater 30 performs cooling by evaporating water in a vacuum state, taking advantage of the fact that the boiling point of water is lowered in a vacuum state, and an absorbent is used to absorb the water of the evaporator and lower the temperature. Lithium bromide (LiBr) can be used as the absorber, and the heat energy recovered from the engine can be utilized as a heat source for regenerating lithium bromide (LiBr). The cooling tower 31 shown in Fig. 1 is provided for cooling the cooling water for condensing the water vapor after separating water absorbed in the absorbent into a water vapor state.

The cold water and the hot water cooled by the absorption type cold / hot water heater 30 are temporarily stored in the cold / hot water tank 32, and the cold or hot water stored in the water tank 32 is cooled or heated by the cooling /

In the case where cooling is carried out by utilizing the absorption type cold / hot water heater, if the amount of inflow of hot and humid air is increased at the same time as in summer, the cooling load for treating the latent heat of hot and humid air rises and the size of the cooler 33 becomes large There is a problem that the installation and operation costs increase and the cooling performance deteriorates.

In this process, since the air is cooled while being in contact with the cold water, the humidity of the air supplied to the room is increased. Therefore, in order to cool the air to the target temperature, the temperature and the humidity are controlled by reheating the air to an appropriate temperature after the air is subcooled until the appropriate humidity is satisfied. Therefore, much energy is required and the efficiency of the system is lowered.

Natural gas is a clean fuel with little greenhouse gas emission during combustion, and therefore, according to the present embodiment, energy such as power and compression days can be produced environmentally using natural gas as fuel.

In addition, the compression work produced by the compressor 310 of the present embodiment can be utilized as cooling / heating energy for cooling or heating the unit to which the three-phase power generation system including the dehumidification cooling apparatus and the dehumidification cooling apparatus according to the present embodiment is applied.

That is, according to the present embodiment, the compressor 310 may be part of the cooling / heating cycle 300 for producing cooling / heating energy.

2, a refrigeration cycle and a heat pump cycle including a compressor 310, a first heat exchanger 320, an expansion means 330, and a second heat exchanger 340 are provided as the cooling / In the present embodiment, the refrigeration cycle and the heat pump cycle are applied as the cooling / heating cycle 300, for example. However, the present invention is not limited thereto, and various types of refrigeration cycle and heat pump cycle can be applied.

The cooling / heating cycle 300 of the present embodiment is a cooling / heating cycle in which the working fluid passes through the compressor 310, the first heat exchanger 320, the expansion means 330 and the second heat exchanger 340 while compressing, And is circulated through expansion and evaporation or condensation processes.

The heating / cooling cycle 300 can be operated differently by changing the circulation direction of the working fluid according to a cooling mode for producing cooling energy and a heating mode for generating heating energy. As shown in FIG. 2, the circulation direction of the working fluid includes a four-way valve V1 for controlling the flow direction of the working fluid introduced into the compressor 310 and the flow direction of the working fluid discharged from the compressor 310 And by controlling the opening and closing direction of the four-way valve V1 by the control unit.

First, the operation principle of the cooling / heating cycle 300 when the triple power generation system including the dehumidification cooling apparatus according to the present embodiment is operated in the cooling mode will be described.

In this embodiment, when the three-phase power generation system including the dehumidification cooling apparatus is operated in the cooling mode, the rotation axis of the engine 100 is coupled with the compressor 310 by the control unit, and when operating in the power- The rotational axis of the engine 100 is controlled to be coupled with both the generator 101 and the compressor 310. [

Hereinafter, for the sake of convenience, the cooling mode is a concept including a cooling mode and a power-cooling mode, and a heating mode is a concept including a heating mode and a power-heating mode. However, the cooling mode and the power-cooling mode, the heating mode and the power-heating mode may be respectively operated, and when the cooling mode and the power-cooling mode are operated, the heating mode and the power- The difference in the timing may be regarded as being the same in the control of the cooling and heating cycle 300 and the dehumidification cooling apparatus 500 in addition to being controlled such that the rotational axis of the engine 100 is not engaged or engaged with the generator 101.

When the triple power generation system including the dehumidification cooling apparatus of this embodiment is operated in the cooling mode, the control unit controls the rotation axis of the engine 100 to be coupled with the compressor 310, controls the cooling / heating cycle 300 to operate , Specifically, the cooling / heating cycle 300 may be controlled to operate in a cooling cycle. In addition, the dehumidification cooling apparatus 500, which will be described later, may be connected to the indoor heat exchanger 500, if required, such that it is determined that cooling energy is further required in addition to the cooling energy generated in the cooling and heating cycle 300, Or may operate the cooling / heating cycle 300 and the dehumidification cooling apparatus 500 to produce the cooling energy. When the control unit controls the cooling / heating cycle 300 to operate in a cooling cycle, the controller may control the dehumidifying cooling apparatus 500 to operate in a cooling mode to be described later, or may control the cooling mode and the regeneration mode to operate simultaneously, It may be possible to control the playback mode to be operated with a time difference after the mode is activated. The operation principle and control of the dehumidification cooling apparatus 500 will be described later and the operation principle of the cooling / heating cycle 300 will be described first.

When operating in the cooling mode, the working fluid passes through the compressor 310, the first heat exchanger 320, the expansion means 330, and the second heat exchanger 340 in this order to complete the cycle.

The working fluid in the vapor state is adiabatically compressed by the power of the engine 100 in the compressor 310 and flows into the first heat exchanger 320 in a state of high temperature and high pressure. In the first heat exchanger (320), the working fluid is equilibrium cooled and condensed into a liquid state. That is, when the cooling / heating cycle 300 is operated in the cooling mode, the first heat exchanger 320 functions as a condenser of the refrigeration cycle. The refrigerant for cooling the working fluid in the first heat exchanger 320 may be air (outside air).

The working fluid having passed through the first heat exchanger (320) passes through the expansion means (330), is thermally expanded, and becomes a low temperature and low pressure state. The expansion means 330 may be an inflator or an expansion valve.

The working fluid having passed through the expansion means 330 flows into the second heat exchanger 340 and is heated by the second heat exchanger 340 under equal pressure and then flows into the compressor 320 again to complete the cycle. When the cooling / heating cycle 300 is operated in the cooling mode, the second heat exchanger 340 serves as an evaporator of the refrigeration cycle. In the second heat exchanger (340), the working fluid cools the cooling / heating fluid while exchanging heat with the cooling / heating fluid.

The working fluid of the cooling / heating cycle 300 according to the present embodiment may be a refrigerant circulating through a known refrigeration cycle or a heat pump cycle, and is not particularly limited. In addition, the cooling / heating fluid according to the present embodiment may be water for cooling / heating or air for cooling / heating to be described later.

Next, the operation principle when the triple power generation system including the dehumidification cooling apparatus according to the present embodiment is operated in the heating mode will be described. When the triple power generation system including the dehumidification cooling apparatus of this embodiment is operated in the heating mode, the control unit controls the rotation axis of the engine 100 to be coupled with the compressor 310, controls the cooling / heating cycle 300 to operate Specifically, the cooling / heating cycle 300 can be controlled to operate with the heat pump cycle. The dehumidifying cooling apparatus 500 may be connected to the heating / cooling unit 300, if necessary, in addition to the heating energy generated in the heating / cooling cycle 300, or the heating / cooling cycle 300 may not be operated. Or the heating / cooling cycle 300 and the dehumidification cooling apparatus 500 may be operated to produce the heating energy. When the control unit controls the heating / cooling cycle 300 to operate with the heat pump cycle, the dehumidifying cooling unit 500 can also be controlled to operate in a heating mode, which will be described later. The operation principle and control of the dehumidification cooling apparatus 500 will be described later and the operation principle of the cooling / heating cycle 300 will be described first.

When operating in the heating mode, the cooling / heating cycle 300 is completed when the working fluid passes through the compressor 310, the second heat exchanger 340, the expansion means 330 and the first heat exchanger 320 in this order do. That is, in the heating mode, the flow of the working fluid is formed in a direction opposite to the cooling mode.

The high temperature, high pressure working fluid vapor adiabatically compressed by the power of the engine 100 in the compressor 310 is introduced into the second heat exchanger 340. In the second heat exchanger (340), the working fluid is equilibrium cooled and condensed into a liquid state. That is, when the heating / cooling cycle 300 is operated in the heating mode, the second heat exchanger 340 functions as a condenser of the heat pump cycle. The working fluid and the cooling / heating fluid exchange heat in the second heat exchanger 340, and the heating / cooling fluid heated by the working fluid is utilized as the heating energy of the room.

The working fluid that has passed through the second heat exchanger (340) passes through the expansion means (330), is thermally expanded, and becomes a low temperature and low pressure state.

The working fluid having passed through the expansion means 330 flows into the first heat exchanger 320 and is heated by the first heat exchanger 320 under equal pressure and then flows into the compressor 32 again to complete the cycle. When the heating / cooling cycle 300 is operated in the heating mode, the first heat exchanger 320 serves as an evaporator of the heat pump cycle. In the first heat exchanger 320, the working fluid receives heat while exchanging heat with the air (outside air) or the arrangement of the engine 100.

The waste heat of the engine 100 supplied as the heat source of the first heat exchanger 320 may be the high temperature engine cooling water discharged after cooling the engine. As shown in Fig. 2, hot engine cooling water circulating along the cooling water line E2 is supplied to the waste heat utilization apparatus described later, that is, the dehumidification cooling apparatus 500 in this embodiment.

According to the present embodiment, a cooling water branch line E2 branched from the cooling water line E2 is provided so that part of the high-temperature engine cooling water supplied to the dehumidification cooling apparatus 500 is supplied to the heat source of the first heat exchanger 320 Can supply.

At this time, a three-way valve (V2) may be provided in the cooling water line (E2), and the control unit controls the opening and closing of the three-way valve (V2) It is also possible to supply the cooling water to the first heat exchanger 320 without supplying cooling water to the dehumidifying cooling apparatus 500 or to supply the cooling water to the first heat exchanger 320 The cooling water is supplied to the first heat exchanger 320 and the cooling water is not supplied to the dehumidification cooling apparatus 500. [

In the case where the heating / cooling cycle 300 is operated as a heat pump cycle for producing hot water in winter, the working fluid in the first heat exchanger 320 must absorb heat from the outside air, and the outside air temperature may not be sufficiently high. At this time, since the working fluid can not sufficiently receive the heat, the heating ability can be reduced. Accordingly, the cooling water is branched from the waste heat recovery apparatus 200 and supplied to the first heat exchanger 320, whereby the working fluid is heat-transferred to be heated to a high temperature. The engine cooling water after the heat exchange in the first heat exchanger 320 can be joined to the cooling water line E2 again and circulated to the gas engine 100. [

In FIG. 2, water is used as an example of the cooling / heating fluid. That is, the air circulating from the room for cooling and heating or the air to be introduced into the room is heat-exchanged with the cold or heated hot water while exchanging heat with the working fluid in the second heat exchanger 340, and cooled or heated by cold water or hot water And enters the room.

The cold water or the hot water cooled in the second heat exchanger 340 can be temporarily stored in the heat treated water tank 400 and the cold water or hot water stored in the water tank 400 can be cooled The dehumidifying cooling apparatus and the dehumidifying cooling apparatus according to the present embodiment can be used as a cold heat or a heat source of the triple power generation system. Alternatively, the cooling / heating fluid may not be stored in the water tank 400 but may be immediately used as a cold heat or a heat source after being heat-exchanged in the second heat exchanger 340.

In the present embodiment, only one compressor 310 may be used, but two or more compressors 310 may be used depending on various power loads and cooling / heating load ratios of a consumer. For example, when two compressors 310 are applied, two compressors 310 may be simultaneously driven, only one compressor 310 may be driven, and the other one compressor 310 may operate in a standby state And in some cases, the compressor 310 may not be driven.

The two or more compressors 310 may be driven with a capacity of 100%, respectively. However, by controlling the bypass valve installed in the compressor 310, the working fluid vapor of the discharge pipe of the compressor 310 A part of the refrigerant can be branched into the suction pipe of the compressor 310 to control the flow rate of the working fluid cyclically circulating the cycle. Alternatively, the operation control of 5 to 100% of the rated cooling / heating capacity is possible through the control of the number of rotations of the compressor 310.

The control of the compressor 310 can be controlled by a control unit (not shown).

Further, the triple power generation system including the dehumidification cooling apparatus according to the present embodiment further includes a waste heat recovery apparatus 200 for recovering waste heat from the gas engine 100. The waste heat recovering apparatus 200 of this embodiment can recover the heat of the hot exhaust gas generated in the combustion byproduct of the gas engine 100 or the heat of the hot cooling water heated while cooling the gas engine 100.

In this embodiment, the exhaust gas discharged from the gas engine 100 may be about 400 to 600 ° C. In FIG. 2, exhaust gas is supplied to the exhaust gas recycling apparatus 200 along the exhaust gas line E 1, So that the heat is recovered and then discharged from the apparatus 200.

In addition, the high-temperature cooling water discharged after cooling the gas engine 100 may be about 70-90 ° C. After cooling the gas engine 100, the discharged cooling water is supplied to the cooling water line E2 to cool down again and to cool the gas engine 100 again.

The waste heat obtained from the waste gas or the cooling water in the waste heat recovery apparatus 200 may be utilized as a heat source of the triple power generation system including the dehumidification cooling apparatus according to the present embodiment and may be utilized outside the system.

2, the exhaust gas of the engine 100 and the cooling water of the engine 100 are heat-exchanged to cool the engine 100 cooling water, and the engine 100 ) The cooling water of the engine 100 heated by the exhaust gas can be utilized as a heat source of a dehumidification cooling apparatus to be described later.

Alternatively, although not shown in the drawing, in the waste heat recovery apparatus 200, steam produced by waste heat of water or exhaust gas heated by the waste heat of the exhaust gas is heat-exchanged with exhaust gas in the tritium generation system or outside the system Or may be supplied as a heat source.

The triple power generation system including the dehumidification cooling apparatus according to the present embodiment further includes a waste heat utilization apparatus that generates additional energy such as electric power or cooling / heating energy by utilizing the heat energy recovered from the waste heat recovery apparatus 200.

In this embodiment, as shown in Fig. 2, the engine cooling water heated by the thermal energy of the exhaust gas in the waste heat recovery apparatus 200 is utilized as a heat source in the waste heat utilization apparatus, The engine 100 cooling water is recirculated to cool the gas engine 100 in a low temperature state.

However, the present invention is not limited thereto, and waste heat can be utilized by providing a heat medium line circulating the waste heat recovery apparatus 200 and the waste heat utilization apparatus, though it is not shown in the drawings. That is, a heat medium obtained by heat exchange in the waste heat recovery apparatus 200 from the exhaust gas or the engine cooling water is introduced into the waste heat utilization apparatus along the heat medium line to transfer the heat energy, and the heat is transferred to the heat utilization apparatus The heat medium having a lower temperature can form a cycle in which the heat medium is recycled to the waste heat recovery apparatus 200 again. At this time, the heat medium may be, for example, fresh water.

In this embodiment, as shown in Figs. 2 and 3, the engine cooling water circulates directly between the waste heat recovery apparatus 200 and the waste heat utilization apparatus.

On the other hand, the waste heat utilization apparatus of the present embodiment is different from the dehumidification cooling apparatus 500 of the present embodiment in that the energy is converted into energy for cooling and heating by using the recovered heat energy. Alternatively, A dehumidifying system for providing a comfortable air by removing water, or an Organic Rankine Cycle (ORC) for converting recovered heat energy into electricity may be applied, or a combination of two or more systems may be applied at the same time.

When an organic Rankine cycle (not shown) is applied as a waste heat utilization device, electric power can be additionally produced using waste heat generated in the gas engine 100. The organic Rankine cycle is a known technique using a modified Rankine cycle using an organic heating medium having a higher vapor pressure than that of water as a working fluid, and a detailed description will be omitted.

For example, when organic Rankine cycle is applied as a waste heat utilization apparatus, the waste heat recovered in the waste heat recovery apparatus 200 can be utilized as an evaporator heat source in the organic Rankine cycle.

In this embodiment, as shown in FIG. 3, it is preferable that a dehumidification cooling apparatus 500 for further producing cooling and heating energy in addition to the above-described cooling and heating cycle 300 is applied.

2 and 3, when the dehumidification cooling apparatus 500 is applied as the waste heat utilization apparatus, it can be utilized as additional cooling and heating energy by using the heat energy recovered from the waste heat recovery apparatus 200.

3, the dehumidifying and cooling apparatus 500 according to the present embodiment is a system for dehumidifying air (hereinafter, referred to as " process air ") that flows along the air lines A1 to A6 and is supplied to the room A desiccant rotor 520 for regulating the temperature of the air passing through the dehumidification rotor 510, a cooling unit 520 for cooling the air passing through the sensible heat rotor 520, A regulator 530; And an air heat exchanger 540 that adjusts the temperature of the target air to a target temperature by using the cold or hot water produced in the above-described cooling / heating cycle 300.

In the present embodiment, the target temperature means a temperature set in the room to be cooled or heated.

The dehumidification cooling apparatus 500 of this embodiment can be operated in the cooling mode, the heating mode and the regeneration mode, and the cooling mode and the regeneration mode can be operated simultaneously, and the regeneration mode can be operated after being operated in the cooling mode It is possible.

First, with reference to FIG. 3, the operation principle when the dehumidifying cooling apparatus 500 according to the present embodiment is operated in the cooling mode will be described. The cooling mode of the dehumidifying cooling apparatus 500 according to the present embodiment is advantageous when the room air is cooled by cooling the object air, and particularly when indoor cooling is performed using object air of high temperature and high humidity in summer. In addition, the cooling mode of the dehumidification cooling apparatus 500 of the present embodiment can be operated simultaneously with or separately from the cooling mode of the above-described cooling / heating cycle 300, and its operation can be controlled by the control unit.

Hereinafter, the introduction temperature of the object air is about 33.4 DEG C on the dry bulb temperature basis, the humidity is about 68.9% RH on the basis of the relative humidity, and the enthalpy is about 21.9 kcal / kg. The target air to be dehumidified and cooled in the apparatus 500 and discharged to the room to be cooled is about 29.7 ° C based on the dry bulb temperature, about 43.6% RH based on the relative humidity, and the enthalpy is about 14.1 kcal / kg I will explain it. Hereinafter, the temperature of the target air at each point is expressed as dry bulb temperature and the humidity is expressed as relative humidity.

The process air to be cooled is introduced into the first air line A1 by using a fan. The high temperature and high humidity air (about 33.4 ° C., about 68.9% RH) flowing into the first air line A1 passes through the dehumidifying rotor 510, and moisture contained in the air is evaporated and removed to control the humidity.

The blower of the present embodiment can be operated by using the electric power produced by the generator 101 combined with the rotation axis of the gas engine 100 described above.

Since the reaction of removing moisture contained in the air in the dehumidification rotor 510 is an exothermic reaction, the air passing through the dehumidification rotor 510 is subjected to high temperature and low humidity. That is, in the dehumidifying rotor 510, material exchange and heat exchange occur at the same time.

The temperature of the air flowing through the second air line A2 after completion of the dehumidification by the dehumidifying rotor 510 is about 70.9 DEG C, the humidity is about 5.6% RH, and the enthalpy is about 24.2 kcal / kg.

The object air having passed through the dehumidification rotor 510 is introduced into the sensible heat rotor 520 along the second air line A2 and is cooled by sensible heat exchange in the sensible heat rotor 520. [ The object air at high temperature and low humidity in the sensible heat rotor 520 can be heat-exchanged with the react air flowing into the sensible heat rotor 520 along the first regeneration line B1 to be described later. However, only the heat exchange occurs in the sensible heat rotor 520, and the substance exchange, i.e., the dehumidification reaction does not occur.

The temperature of the cooled object air passing through the sensible heat rotor 520 is about 29.7 DEG C, the humidity is about 7.6% RH, and the enthalpy is about 22.5 kcal / kg.

The cooled object air passing through the sensible heat rotor 520 can be introduced into the cooler 530 along with the third air line A3 and further cooled in the cooler 530. [

The cooler 530 of the present embodiment is preferably a regenerative evaporative cooler 530. The regenerative evaporative cooler 530 is composed of a dry channel and a wet channel, and the object air introduced along the third air line A3 is cooled while passing through the dry channel, and some of the cooled air passing through the dry channel And the remaining part is discharged along the fifth air line A5. In the dry channel, the object air is cooled by the heat of vaporization, i.e., cold heat, generated by the air passing through the wet channel evaporating moisture from the wet channel surface.

The flow rate of the object air flowing into the wet channel through the dry channel may be about 1/3 to 1/5 of the object air flow rate introduced into the fifth air line A5 through the dry channel.

It is also preferable that the flow direction of the object air passing through the dry channel and the flow direction of the object air passing through the wet channel are opposite to each other.

In addition, the air having passed through the wet channel and having evaporated the water on the surface of the wet channel can be re-joined to the front end of the dehumidifying rotor 510, that is, the first air line A1.

In this embodiment, the cooled object air passing through the regenerative evaporative cooler 530 may be introduced into the air heat exchanger 540 along the fifth air line A5. In the air heat exchanger 540, the cold water flowing along the cold / hot water branch line W3 branching from the cooling / heating line W2 through which the cold water cooled by the second heat exchanger 340 flows and the cold water flowing along the cold / ) Is subjected to heat exchange. The target air is adjusted to a predetermined value, that is, the temperature required in the room by the heat exchange in the air heat exchanger 540, and is supplied to the room by the blower.

3, target air having passed through the sensible heat rotor 520 flows into the regenerative evaporative cooler 530 along the third air line A3 to be further cooled, (540) and then cooled, thereby adjusting the target temperature and humidity.

However, the target air may be cooled while passing through both the sensible heat rotor 520 and the regenerative evaporative cooler 530 and the air heat exchanger 540, and the sensible heat may be generated by the sensible heat rotor 520 and the cooler 530, the air heat exchanger 540 Or the like). However, in the sensible heat rotor 520, only the heat exchange occurs without the substance exchange, and the humidity can be raised by the heat exchange in the regenerative evaporative cooling device 530 and the air heat exchanger 540. Therefore, it can be freely configured according to the introduction temperature, humidity, target temperature and humidity of the target air.

For example, in the case where the object air that has been dehumidified while passing through the dehumidification rotor 510 is configured to be cooled only in the regenerative evaporative cooler 530 without being cooled in the sensible heat rotor 520 and the air heat exchanger 540, The target air having passed through the regenerative evaporative cooling device 530, that is, the target air of about 70.9 ° C, about 7.6RH, and about 24.2 kcal / kg is introduced into the regenerative evaporative cooling device 530 and cooled, The temperature of a target air is about 29.7 ° C, the humidity is 43.6% RH, and the enthalpy is about 14.1 kcal / kg.

The amount of cooling heat required in the introduction and discharge conditions of the object air is about 8.3 kW. When the object air is dehumidified and cooled using the dehumidification rotor 510 and the air heat exchanger 540, the amount of heat consumed is about 10.5 kW and the system efficiency is about 0.79. On the other hand, when the target air is cooled using the dehumidification rotor 510, the sensible heat rotor 520 and the air heat exchanger 540, the amount of heat consumed is about 8.7 kW and the system efficiency is about 0.95. When the object air is cooled using the dehumidification rotor 510, the regenerative evaporative cooler 530 and the air heat exchanger 540, the heat consumption is about 6.3 kW and the system efficiency is about 1.32.

Therefore, according to the present embodiment, the dehumidification rotor 510, the sensible heat rotor 520, and the reconditioning evaporation system 520, which are different from the absorption cooling system in which the humidity after the cooling of the existing air is adjusted, Adding the cooler 530 increases the equipment installation cost, but it does not require reheating the system after it has been supercooled to regulate the humidity, thereby reducing the consumption of heat, reducing operating costs, and increasing system efficiency.

According to the present embodiment, before the object air is cooled, it is passed through the dehumidification rotor 510 to remove moisture and adjust the humidity, thereby treating the latent heat load by the moisture contained in the air before cooling, Can be reduced. Further, since the latent heat load of the target air is treated and then cooled, the cooling performance can be sufficiently exhibited even if the flow rate of the object air introduced into the dehumidification cooling apparatus 500 of this embodiment is large or the introduction temperature is high.

Next, the operation principle when the dehumidifying cooling apparatus 500 according to the present embodiment is operated in the regeneration mode will be described with reference to the dehumidification cooling apparatus 500 of this embodiment and the above-described third embodiment. The regeneration mode of the dehumidification cooling apparatus 500 according to the present embodiment can be operated simultaneously with or separately from the cooling mode of the dehumidification cooling apparatus 500 and the cooling mode of the cooling and heating cycle 300 described above, And can be controlled by a control unit.

The dehumidification rotor 510 described above may be in the form of a rotating rotor and may be coated with a moisture absorbent that absorbs or adsorbs moisture in the target air. The performance of the moisture absorbent gradually decreases while continuously absorbing or adsorbing moisture in the object air. Therefore, in the dehumidification rotor 510, a dehumidification reaction occurs on one side of the rotor and a regeneration reaction occurs on the other side. The regeneration mode of the dehumidification cooling apparatus 500 regenerates the desiccant to maintain the performance of the dehumidification rotor 510.

React air for regenerating the dehumidification rotor 510 is introduced into the sensible heat rotor 520 through the first regeneration line B1 using a blower. The regeneration air in the sensible heat rotor 520 can exchange heat with the object air dehumidified in the dehumidification rotor 510 as described above. At this time, only heat exchange occurs between the target air and the regeneration air, and no material exchange occurs.

In the sensible heat rotor 520, the reconditioning air is exchanged with the target air to cool the target air, and the reconditioning air is heated. The regeneration air whose temperature has risen while passing through the sensible heat rotor 520 is introduced into the first regeneration heater 550 along the second regeneration line B2.

The first regenerating heater 550 heats the regeneration air for regenerating the dehumidifying rotor 510 to a temperature necessary for removing moisture adsorbed or absorbed by the dehumidification rotor 510. As the heat source for heating the regeneration air in the first regenerative heater 550, waste heat of the engine 100 described above can be utilized.

Preferably, engine cooling water circulating along the cooling water line E2 can be utilized. More specifically, as shown in Fig. 2, high-temperature engine cooling water after cooling the gas engine 100 can be utilized as a heat source. The temperature of the hot engine coolant after cooling the gas engine 100 may be about 70-90 < 0 > C.

The engine cooling water that is cooled while the regeneration air is heated by the first regenerative heater 550 may be circulated to cool the engine 100 as cooling water of the engine 100 again.

3, the first regenerative heater 550 is connected to the cooling water line E2 and is connected to the engine 100 through the cooling water line E2 as a heat source for heating the reconditioning air, Of cooling water is described as a preferred embodiment, but the present invention is not limited thereto.

For example, as the heat source for heating the regeneration air in the first regenerative heater 550, the exhaust gas of the engine 100 may be directly supplied along the heat source supply line connected to the first regenerative heater 550 Alternatively, steam generated by heat exchange with the first fluid heated by heat exchange with the exhaust gas of the engine 100, for example, water or exhaust gas, may be supplied from the waste heat recovery apparatus 200.

Alternatively, the second fluid heated by heat exchange with the high temperature cooling water discharged from the waste heat recovery apparatus 200 after cooling the engine 100 may be supplied from the waste heat recovery apparatus 200 to the first regenerative heater 550 May be supplied along the line.

The regeneration air heated by the high temperature engine cooling water in the first regenerating heater 550 is introduced into the dehumidifying rotor 510 to regenerate the dehumidifying rotor 510. The regeneration air is supplied to the dehumidifying rotor 510 The second regenerative heater 560 can be further heated.

The heat source for heating the reconditioning air in the second regenerative heater 560 may be electricity. The second regenerative heater 560 is a regenerative heater in which the temperature of the regeneration air heated by the first regenerative heater 550 is not sufficient to regenerate the dehumidification rotor 510, Can be activated in a situation.

The electricity used in the second regenerative heater 560 may be produced by the generator 101 described above.

The regeneration air heated to a temperature sufficient to regenerate the dehumidification rotor 510 while passing through the first regeneration heater 550 or the second regeneration heater 560 or the first regeneration heater 550 and the second regeneration heater 560, Is introduced into the dehumidification rotor 510 along the third regeneration line B3

The regeneration air that has completed the regeneration reaction in the dehumidification rotor 510, such as evaporating water absorbed or adsorbed by the desiccant in the dehumidification rotor 510, is discharged into the air along the fourth regeneration line B4.

That is, the cooling mode and the regeneration mode of the dehumidification cooling apparatus 500 according to the present embodiment can be performed simultaneously or individually. However, it is preferable that the dehumidification rotor 510 is provided in the form of a rotating rotor, and the cooling mode and the regeneration mode are simultaneously operated so that the dehumidification reaction occurs on one side and the regeneration reaction occurs on the other side.

Next, a heating mode of the dehumidification cooling apparatus 500 according to an embodiment of the present invention will be described.

The heating mode of the dehumidifying cooling apparatus 500 according to the present embodiment can be operated when it is intended to supply to the room to be heated, that is, mainly in winter. In addition, the heating mode of the dehumidification cooling apparatus 500 of this embodiment can be operated simultaneously with or simultaneously with the cooling mode of the above-described heating / cooling cycle 300, and the operation thereof can be controlled by the control unit.

When the dehumidifying cooling apparatus 500 of this embodiment is operated in the heating mode, it is preferable that the dehumidification rotor 510 and the regenerative evaporative cooling unit 530 are not operated by the control unit since dehumidification in the air is not necessary . Also, the sensible heat rotor 520 may not be operated.

That is, the air to be introduced into the first air line A1 through the blower is branched from the second air line A2, the third air line A3 and the third air line A3, 530 and the fifth air line A5 to the air heat exchanger 540 and is heated in the air heat exchanger 540. [

3, the target air is introduced into the first air line A1 connected to the blower and passes through the dehumidifying rotor 510 and the sensible heat rotor 520. However, like the fourth air line A4, A bypass line branched from the first air line A1 and the second air line A2 is provided to be introduced into the air heat exchanger 540 without passing through the dehumidification rotor 510 and the sensible heat rotor 520 It is possible.

The heat source for heating the target air in the air heat exchanger 540 can utilize the waste heat of the engine 100 described above. Preferably, it may be hot water supplied along the cold / hot water branch line W3.

The object air heated by the heat exchange in the air heat exchanger 540 is supplied to the room to be heated through the blower.

The fourth air line A4 can be controlled so that the target air is introduced into the fourth air line A4 by adjusting the open / close valve provided in the fourth air line A4 and controlled by the control unit. That is, the control unit may control to open the on-off valve when operating in the heating mode, and to close the on-off valve when operating in the cooling mode. Also, the opening / closing valve may be partially or wholly opened depending on the target temperature even in the cooling mode so that some or all of the target air may be controlled to bypass the regenerative evaporative cooler 530.

As described above, according to the dehumidification cooling apparatus, the triple power generation system including the dehumidification cooling system, and the operation method thereof, power and compression work can be produced by the power of the gas engine 100, Energy can be produced individually or simultaneously.

The control unit controls the coupling and disengagement of the generator 101 and the compressor 310 connected to the rotation axis of the engine 100 and controls the flow direction of the working fluid in the cooling and heating cycle 300 including the compressor 310 And controlling the operation of the dehumidifying cooling apparatus 500 enables production of electric power, cooling energy and heating energy to be independently controlled, thereby controlling the heat and cold ratio. Accordingly, the imbalance between demand and supply can be solved, and the system can be configured for each heating / cooling unit, so that the energy loss can be reduced and the system efficiency can be improved.

The operation of the dehumidifying rotor 510, the sensible heat rotor 520, the regenerative evaporative cooler 530 and the air heat exchanger 540 constituting the dehumidification cooling apparatus 500 and the operation of the dehumidification cooling apparatus 500 The temperature and the humidity of the object air can be independently controlled by controlling the flow rate and the flow rate of the object air or the regeneration air flowing in the flow path.

In addition, the dehumidification cooling apparatus 500 can reduce the cooling load of the object air by adjusting the humidity in the object air first and then adjust the temperature, and maintain the cooling performance regardless of conditions such as temperature, And can reduce operating costs.

In addition, since the waste heat of the engine is recycled using the gas as the fuel, the waste heat of the engine can be recycled, and the air dehumidification and the cooling / heating energy can be additionally produced.

In addition, since the cooling and heating cycle 300 and the dehumidification cooling apparatus 500 are provided in the form of modules, installation and application of each unit is easy.
