Description

Evaporative air conditioning system combined with cooling tower using open porous metal {EVAPORATIVE AIR CONDITIONER COMBINING WITH COOLING TOWER USING OPEN METAL FORM}

The present invention relates to an evaporative air conditioner combined with a cooling tower using an open porous metal, and in particular, when used in a domestic gas-absorbing air conditioner, an air conditioner having heat and ventilation functions and an evaporative air conditioner that can be used as a cooling tower. It relates to an exchange device.

In general, the air conditioner is a device that provides a comfortable environment by lowering the temperature of the hot air, the most common is a compressed air conditioner. Compressed air conditioners can be lowered to a desired temperature by using a relatively simple structure and a freon refrigerant compared to other air conditioners, and this cooling method is used for refrigeration, refrigeration, and heating.

However, the freon refrigerant is not environmentally friendly, such as destroying the ozone layer, and the energy of the driving device of the compressor mainly uses electric energy, and thus it is refrained from being used in areas with high electric charges.

Compressed air conditioners can be divided into air-cooled and water-cooled according to the cooling method of the condenser, and there is also a portable air conditioner (air conditioner) in which water is injected into the condenser by using latent heat of evaporation to exhaust the latent heat of evaporation.

Considering the principle of evaporation, a compressed air cooler also evaporates a freon refrigerant through an expansion valve and evaporates it in an evaporator, and heat exchanges it with a desired medium or air. Refers to an air conditioner that uses the principle of water evaporation, that is, creates a condition that is easy to evaporate water, and then cools it by passing air to be cooled.

In the air conditioner market, there is often called a cold air blower, which includes an ice pack or an ice storage container, and circulates water to cool the water and air to discharge the cooled air. The cooler is not included in the evaporative cooler here.

There are two types of evaporative coolers: direct evaporation and indirect evaporation. The direct evaporation method uses the evaporative humidification material to wet the water or injects and cools the air after passing through the heat exchange. Direct use of air for cooling is a direct evaporative air conditioner (Korea Patent No. 0328348), and its commercialized products are manufactured and sold by various US companies. This direct evaporative cooler is a very effective cooler in hot and dry areas. However, in the high temperature and high humidity area, the cooling effect is reduced, that is, the cooling temperature difference is small and the humidity is high, which makes it unpleasant and difficult to use.

Therefore, the method of dropping only the temperature without raising the humidity is an indirect evaporative air conditioner (Korean Patent No. 2000-0020820). The indirect evaporative air conditioner can exchange the suction channel with evaporative humidification and intake air to supply a drop in temperature (dry channel) to provide a comfortable cooling air compared to the direct evaporator.

Such an indirect evaporative cooler is a type of inhaled air passing through the gun channel through which heat is exchanged with the wet channel, and partly sucked into the wet channel to be discharged with latent heat of evaporation. It is known as evaporative cooling, and it can theoretically lower the dew point temperature lower than the wet bulb temperature of the intake air, so that it can be discharged at a lower cooling temperature than other evaporation types (Korean Patent No. 2002-0061735).

The above-described regenerative evaporative air conditioner folds a thin thin plate into a corrugated shape and brazes it on a separating plate to form a heat exchange fin to modularize the heat exchanger, and combine the wet channel with the gun channel. When the air in the place to be cooled is sucked in and passed through the gun channel, heat transfer is made and cooled through the separator plate cooled by latent heat of evaporation in the wet channel, and some air is directed to the wet channel to cool the wet channel. It is discharged to the outside and most of the cooling air is discharged to the cooling request space to cool.

The heat exchange method using a heat exchange fin having a thin metal plate in a corrugated shape is an efficient method that is generalized, but a hole is appropriately disposed in the corrugated heat transfer fin provided in the wet channel, and water from the upper portion is transferred to the heat transfer fin. It is configured to spread. However, if the surface fins of the water do not penetrate the heat-treating fins, the spreadability is poor and the evaporation efficiency is reduced, and the water may be stagnant between the heat-exchanging fins and the fins. This will block the flow and cause poor heat transfer.

In addition, a common problem of evaporative air conditioners is that it is impossible to theoretically lower the difference in cooling temperature below the ambient temperature or the dew point temperature of the intake air. The temperature of the cooling air is absolutely dependent on the temperature and humidity of the intake air.

Of course, there is no problem if the intake air temperature or the outside temperature is a possible time or place for the desired cooling temperature, but the temperature and humidity of the season requiring cooling are not always the same. In addition, when cooling is required in a rainy season in which humidity is high, there is no condensation heat exchange dehumidification function due to a low cooling temperature, and unless there is a dehumidifying function using a separate absorbent, it may be unpleasant to have a dehumidifying function.

In the air conditioning equipment using the principle of evaporation, the principle of water evaporation is used, but the evaporation is made more active, the vacuum is made to evaporate at a lower temperature, and the evaporated refrigerant (water vapor) is absorbed using an absorption solution and regenerated by There is an absorption formula using the principle of absorption and evaporation used.

Absorption type is called absorption type chiller by using absorption solution, and the heating source is the direct heating type of combustion type called absorption type cold and hot water machine.

Among the absorption type cold and hot water heaters, gas consumption is less than 25 kw as a system including an indoor unit.

Absorption air conditioner has a heat exchanger, that is, an indoor unit in a place to be cooled, and sends water or air cooled (7 ℃ ~ 12 ℃) to the room through heat exchange in an evaporator where water of refrigerant is evaporated and cooled in an absorption air conditioner. Conduct.

Absorption type absorbs the evaporated refrigerant and absorbs a lot of heat to cool it (take it outside), absorbs the refrigerant from the regenerator and heats it to regenerate the diluted solution (regenerator) and regenerates the refrigerant. The heat of condensation of the condenser 21 for condensing the heated water vapor must be cooled. Therefore, according to the cooling method of condensation heat and absorption heat, it is classified into air-cooled, water-cooled, and combined type (by spraying and exhausting water to cool by using latent heat of evaporation in air-cooled heat exchanger). This is used.

This type of water cooling is a typical cooling tower cooling method with high reuse rate of water resources. Household gas-absorbing air conditioners that have emerged to date have made such cooling towers cross-flow type.

The amount of cooling heat that needs to be cooled in a cooling tower is about 1.8 times the amount of cooling that is used in an absorption air conditioner. In terms of efficiency, the cooling method using a cooling tower requires 1.8 times more heat than the method using an absorption air conditioner. It is very poor efficiency.

Absorption Chiller is an eco-friendly product that does not use Freon refrigerant, unlike compressed air. It is free from the regulation of Freon refrigerant and eliminates supply and demand imbalance between electric energy and gas energy as it does not use electric energy as the main driving energy source. It is evaluated as a beneficial product. In addition, when using waste heat, the energy use efficiency is high, and when gas energy is used as an energy source, there is almost no energy transfer loss compared to electric energy. However, the efficiency of the absorption chiller is about 1.2 ~ 1.3 for the dual efficiency, and the gas energy is used as the main energy source, and some electric energy is used to drive the pump. It is also true.

At present, many efforts are being made to increase the efficiency such as the triple utility to increase the efficiency. In energy conservation and environmental preservation, especially in the energy source of electrical energy produced in the country in the (regulations to reduce greenhouse gas emissions that cause climate change agreements, global warming) protocol for CO ₂ reduction of natural gas that In consideration of the above, electrical energy is also a source of CO ₂ by gas combustion in terms of electrical energy production, and gas-absorbing air conditioners that burn and cool gas are not free from restrictions on CO ₂ reduction.

Therefore, the freedom to regulate CO ₂ reduction is to reduce the use of energy, and to develop and use devices that are more effective, more efficient, or use less energy.

The biggest weakness of absorption chillers or air conditioners is the cooling method. Even with the cooling tower, which is known to be the most efficient, if the temperature is close to 38 ℃ and the weather is hot, humidity will be an important factor, but the cooling water of 38 ℃ from the absorber will not be lowered to 32 ℃. . In this case, it may not be possible to put ice in the cooling tower. In areas where such high temperatures and humidity continue, it is not suitable to use the air conditioner without changing the system. However, in Korea, it is rare to see such an increase in temperature, which is a suitable environment for using an absorption refrigerator.

It seems to be very inefficient that the amount of heat cooled in the cooling tower is 1.8 times the amount of cooling used in absorption chillers. Because the principle of the evaporative air conditioner is the same as the cooling principle of the cooling tower. Nevertheless, the absorption air conditioner is in the spotlight because it is to produce a cold water of 7 ℃ ~ 12 ℃ to fully exhibit the effect of the cooling to create a corresponding cooling air temperature. This temperature is also because the dehumidification function can be easily provided. In addition, the initial temperature to be cooled in the cooling tower is to cool the temperature of about 38 ℃ (design temperature, the temperature discharged through the condenser outlet pipe 24 in the condenser 21) to a temperature of about 32 ℃. However, this is because the temperature of the water at 38 ° C, which is the discharge water temperature discharged through the condenser discharge pipe 24 of the condenser 21, has a large temperature difference from the outside air temperature, so that the cooling performance is relatively large due to the temperature difference.

The evaporative air conditioner has the same amount of cooling heat as the cooling heat amount, so that the amount of heat removed is higher for the energy used than the absorption type, and the absorption chiller or air conditioner has a large cooling temperature difference, and thus an effective cooling temperature can be produced. The disadvantage would be the opposite.

On the other hand, domestic air conditioners have been coped with gas boilers or direct-heat heaters for cooling in winter, heating for winter, and compressed air for cooling. Therefore, coping with high humidity in summer and dryness in winter, especially in apartment buildings or buildings, is at a very low level. In addition, new tenants are exposed to various harmful substances. Current ventilation systems for these hazardous environments have been to manually open the windows periodically to ventilate them, hang clothes when dry, or use humidifiers.

In particular, the main cause of pollution of indoor air at home is the use of cooking gas table. For example, in order to increase energy efficiency, the insulation of the building is almost perfect, and the sealing ability is also good, and the only means of exhaust are the exhaust fan and the toilet fan, where the exhaust of the cooking exhaust gas is attached to the cooking place such as the kitchen. If it does not, the exhaust will not be smooth, making it difficult to see with good ventilation or systems. Ventilation seems to be the only solution, and if you open the window while operating the compressed air conditioner in the heat of the year, it is unpleasant to open the window frequently during the heating period in winter. It's work. However, to maintain a healthy lifestyle, it is good to have frequent ventilation.

In the conventional absorption type hot and cold water heater, the heating hot water production cycle can supply stable high temperature heating hot water (55 ° C. to 60 ° C.), while other methods are limited by outdoor temperature and load. The heating method of absorption type cold and hot water heater varies according to manufacturers, but it is classified into three types as follows. Either way uses the latent heat of condensation as a heating source for the refrigerant vapor generated in the hot regenerator.

First, the evaporator method is a method in which heating hot water is obtained from the evaporator in the same manner as cold water in cooling. The (heating and heating switching) valve is opened between the high temperature regenerator and the evaporator, and the refrigerant steam generated in the high temperature regenerator is directly transferred to the evaporator to heat the heating hot water. The refrigerant (liquid) condensed in the evaporator is combined with the absorbing solution in the absorber and sent to the high temperature regenerator by the (absorption) solution pump for operation. This method is a simple cold and hot water piping system.

Secondly, the absorber / condenser method is a method of extracting heating hot water from a cooling water system in a cooling operation. The heated hot water is preheated by the heat of the absorbing solution of the absorber, and the condenser 21 is heated by the refrigerant vapor generated from the low temperature regenerator. There is also a way to make hot water by condenser alone.

Third, the dedicated hot water heat exchanger method is a method of manufacturing from a dedicated hot water heat exchanger installed for the purpose of manufacturing hot water. The hot water is heated by the refrigerant steam generated from the high temperature regenerator, and the refrigerant condensed in the water heater flows into the high temperature regenerator. The cold side of absorber, evaporator, condenser and low temperature regenerator shall be closed with a heating and heating valve. However, when the hot and cold water is produced at the same time, hot water can be produced in a dedicated hot water heat exchanger simultaneously with the operation of the cooling cycle. The hot water here can be used as heating hot water, and can also be used as hot water other than the purpose of heating water.

The heating method of the home gas absorption air conditioner currently in use is to condense the refrigerant vapor generated from the (high temperature) regenerator in the space where the evaporator is located and condense it and send the water flowing in the evaporator pipe to the indoor unit or to the floor heating pipe for heating. The first is the evaporator method. Such a heating method has an advantage that the size of the absorption type air conditioner can be made compact.

However, the heating of the home gas absorption air conditioner is limited by the condensation capacity of the evaporator. In addition, the production of this type of hot water and sending it to an indoor unit or a floor heating pipe for heating makes the dry air in the indoor room more dry. The domestic climate is influenced by monsoons, with a cold and dry climate in winter and a warm and humid climate in summer. Also, because it is located on the east coast of the continent, winter is colder than other regions located at the same latitude, and the temperature difference between summer and winter is severe. This heating method does not have a humidification function, the relative humidity is lowered by heating the room air for heating in a dry winter, there is a problem that becomes more dry.

Accordingly, an object of the present invention is to provide a cooling tower combined evaporative air conditioner using an open porous metal that takes advantages of an evaporative air conditioner and an absorption air conditioner, and conflicts with disadvantages to provide high energy use efficiency and comfortable air-conditioning air. .

In addition, another object of the present invention is that the window does not need to be frequently ventilated during the heating period in winter, and in addition to the cooling tower combined evaporative air conditioning using an open porous metal that can keep the humidity properly in summer It is to provide a device.

In addition, another object of the present invention is to improve the moisture channel of the evaporative air conditioner to provide an evaporative air conditioner with excellent heat transfer characteristics, and the disadvantages of the evaporative air conditioner and the disadvantages of domestic gas absorption air conditioner, mutually mutually harmonized, utilizing the advantages Providing energy-saving equipment to reduce the amount of CO ₂ generated by providing equipment, provide eco-friendly cooling and heating, eliminate the pollution of the current indoor air, and use the open-type porous metal evaporative air conditioning system using open porous metal to improve national health Is in providing.

In addition, another object of the present invention is to increase the cooling humidity to the indirect evaporative cooler of the method of dropping only the temperature without raising the humidity does not cause discomfort, the air is sucked through the gun channel through which heat exchange with the wet channel A part of the wet channel is sucked in and discharged with latent heat of evaporation. The method can theoretically lower the dew point temperature lower than the wet bulb temperature of the intake air to apply a heat exchange medium having excellent heat exchange capability to the wet channel and the dry channel. It can increase the heat exchange capacity, improve the spreading of water in the wet channel, thin the water film and increase the evaporation area, provide the high efficiency evaporation capacity, and the intake air can selectively suck external fresh air. The present invention provides a cooling tower combined evaporative air conditioner using an open porous metal.

In addition, another object of the present invention is to use the evaporative air conditioner as the cooling tower function of the domestic gas absorption air conditioner to lower the cooling temperature required by the evaporative air conditioner in the summer cooling period as an evaporative air conditioner. In addition, when the outside air temperature is required to cool down by the evaporative air conditioner is required to operate a domestic gas absorption type air conditioner, the evaporative air conditioner of the present invention provides a heat exchange device to function as a cooling tower, evaporative air conditioner and absorption type It takes advantage of air conditioner and air conditioner and provides air conditioning equipment and air conditioning system that provides high energy efficiency and pleasant cooling air by competing disadvantages, while domestic gas absorption type air conditioner manufactures cold water of low temperature and sends it to indoor unit to use condensation phenomenon. Open porosity for dehumidifying To provide a cooling tower combined with an evaporative air conditioner in the.

In addition, another object of the present invention is to use the structure and method that the cooling tower can use the absorber and condenser in the same container as the evaporator for heating or hot water production in case of heating using condensation of the evaporator. When operating the heat exchanger in the heating mode, water is flowed into the pipe connected to the absorber-condenser-cooling tower, and the hot water flowing through the absorber and the condenser passes through the heat exchanger of the present invention to obtain heating air, or Combined with a cooling tower using an open-porous metal to inhale the air used for heating, provide a water supply unit in the heat exchange channel to increase the temperature of the air, and provide a heat exchanger to increase the humidity to provide the function of humidifying dry air in winter. It is to provide an evaporative air conditioner.

When used as an evaporative cooler, the circulation of the coolant is lower water tank (73)-cooling water pump (11)-three-way valve (26)-upper water tank (74) spray nozzle (10)-wet channel (2) (filler, open type) Circulating in the order of the porous metal (3)-the lower tank (73), and when used as a cooling tower of the home gas absorption air conditioner (17), the circulation of the cooling water is the lower tank (73)-cooling water pump (11)-three-way valve ( 26)-Absorber (20)-Condenser (21)-Upper water tank (74) Spray nozzle (10)-Wet channel (2) (filler, open porous metal)-Lower water tank (73) And the evaporative humidification exhaust air 80 is arranged by a wet channel intake fan 9 (a cooling fan in the case of a cooling tower).

The cold air or cold water produced by the home gas absorption air conditioner 17 is sent to the indoor unit 82 to perform cooling. The temperature of the cold water (7 ° C. to 12 ° C.) is large because the temperature difference between the room and the indoor air is dehumidified. Driving is possible.

The evaporative air conditioner of the present invention may be used as a heating device in the case of an evaporative heating method that is connected to a home gas absorption air conditioner 17 and used in the same space as the evaporator 19 when used as a heating device. Since the absorber 20 and the condenser 21 are in contact with the high temperature refrigerant vapor generated in the high temperature regenerator 18, when the coolant pump 11 is operated, the absorber 20 and the condenser 21 are heated by condensation. Hot water flows in and flows into the wet channel 2 of the evaporative air conditioner and raises the temperature of the heat exchanger 6. Here, when the operation of the wet channel intake fan 9 is stopped and the gun channel intake fan 8 is operated, the air heated through the heat exchanger 6 is discharged to a heating place and used for heating.

The open porous metal 3 has a large surface area ratio per unit volume (790-2740 m ² / m ³ ), is light (porosity 90-95%), and can be vacuum or deep brazed at high strength. In addition, the open-type porous metal is easy to heat treatment, coating and cutting, such as good machinability, high shock and noise absorption.

In addition, the material of the porous metal (Metal Foam) may be made of Al, Cu, Ni, etc., and when using the porous metal as a heat exchange pin (filler) with Cu has a fast heat transfer effect and also has a sterilizing effect Can act as a sterile filter. It can play a role in the prevention of habitat against various germs that can inhabit the heat exchanger (cooling tower).

By using open porous metal (3) (OPEN CELL METAL FOAM) which has excellent absorption and spreadability only by heat treatment during brazing, the distribution of cooling water is excellent as a filler, so it is excellent as a filler and has a high surface area. Evaporation, cooling, transfer, and heat exchange are performed at the same time. Because the porous metal has a metallic connection structure, the overall temperature distribution in the porous metal is constant due to the heat transfer effect. This uniformity increases cooling efficiency and performance. .

In addition, by using open porous metal, the heat exchanger channels can be modularized in units, and several can be arranged up, down, left, and right, and can be increased or decreased in accordance with the capacity.

First, the open plated porous metal 3 in the form of a plate may be formed on the metal plate 5 by a brazing method. Alternatively, the open plated metal 3 may be attached to the heat exchanger 6 to heat the mold. The exchanger 6 is placed, and the mold casting slurry (ceramic powder) and the bubble size polymer are mixed and molded, heated to remove the polymer (Burnout), the mold is filled with metal, cooled, and the mold material is removed by tapping to complete it. There is a method (DUOCELL), there is a CVD (Chemical Vapor Deposition) method to shape the shape into an open porous polymer and complete it by chemical substitution.

Meanwhile, in the case of the gun channel 1, the heat exchanger 6 may be completed by inserting and brazing the corrugated fin for heat exchange without attaching the open porous metal 3.

In particular, when the pores of the open porous metal 3 are small and the width of the channel is very narrow, the use of corrugated fins for heat exchange is a method of reducing air flow resistance.
