Description

Air water system with external air temperature control device {Air water system}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an air-water system equipped with an external air temperature regulating device, and more particularly, to a technique for generating water by heating cold air in the air to a dehumidifying device of an air-

In a typical refrigeration cycle, a high-temperature, high-pressure gas produced by a compressor is drawn into the air by the heat of the compressed gas refrigerant in the condenser, and then becomes liquid again.

This liquid is pushed to the capillary (the expansion valve) and again cooled to the gas evaporator or frozen.

In order to make refrigerating through the evaporator, it is necessary to cool the high-temperature and high-pressure refrigerant in the condenser. In the tropical climate, the external temperature is high (about 30 ° C. to 40 ° C.)

There is a problem in cooling the refrigerant flowing through the condenser, and the evaporator does not function.

As a result, water production of the air water is not smooth and hatching occurs in the refrigeration cycle, resulting in malfunction of the device.

To solve these problems, the inventor repeatedly researched and experimented with the air water system to supply air water to water-scarce countries in tropical countries.

As a result of the study, it was found that the technical composition revealed in this case was the most effective for water production. Consider this effort and look at this technique.

Generally, as the industrialization has developed and the pollution of the water caused by the increase of pollutants has intensified, tap water has been purified by using a water purification device such as a water purifier, or bottled water sold in the market has been purchased and used.

Generally, a water purifier is used to purify water that is present like a river,

The water is supplied as raw water and passes through a number of filters, and is subjected to a process such as precipitation, filtration, sterilization, etc., and the harmful substances contained in the tap water are purified,

However, there is a problem that it is difficult to use a conventional water purifier using raw water in a region where it is difficult to supply the raw water smoothly.

Accordingly, when the air temperature is lowered, the relative humidity becomes higher. At the temperature (dew point temperature) at which the relative humidity becomes 100%, the water vapor exceeding the saturated water vapor condenses and changes into water. There has been developed a device for obtaining raw water by condensing water vapor in the air by cooling and purifying raw water obtained by this method and providing it as potable water.

Conventionally, Korean Patent Laid-Open Nos. 2005-0027843 and 2010-0104336 disclose a compressor for compressing gaseous refrigerant at a high temperature and a high pressure by sucking outside air and a high-temperature and high-pressure refrigerant gas discharged from the compressor A condenser and an evaporator for evaporating low-pressure refrigerant passed through the expansion tube through the condenser, condensing the moisture in the air to generate a predetermined amount of raw water, and purifying the generated raw water to provide it as potable water But

This method produces little or no water if it is cold (eg, less than 10 degrees) air in winter.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a technique for generating water by heating the cold air in the air to reach the dehumidifying device of the air water system.

Providing the above technique can produce seasonal water.

First, referring to the accompanying drawings,

First, the configuration according to the present invention will be described. A condenser 26 for condensing high-temperature and high-pressure refrigerant gas discharged from the compressor 27, a condenser 26 for condensing the refrigerant gas discharged from the condenser 26 An evaporator 25 for evaporating a low-pressure refrigerant that has passed through a tube (capillary tube)

A second blowing fan 26 'for blowing air to the outside through the condenser 26 via the evaporator 25 and the water generating unit, and an evaporator 25 And the other side of the body 50 has an air inlet 52 through which the outside air flows and the air inlet 52 is connected to the air inlet 52 ' And a space portion 54 formed between the connection hole 51 and the heater portion 53. The heater portion 53 may be formed of a metal such as aluminum or the like.

In the description 60 and 61, the air introduced through the air inlet is obstructed so that the air is dispersed in the space or an external shape is generated, so that the air heated by the heater can be dispersed throughout the space.

When dispersed in this way, the temperature of the high temperature (about 60 degrees or more) of the air heated by the heater is lowered.

If the air introduced into the air inlet passes through the heater and the connecting hole without being dispersed, the dehumidifying efficiency may be lowered because the introduced air is at a high temperature.

Hereinafter, an embodiment will be described.

A second air blowing fan 26 ', and a heater 53 installed at a portion of the air inlet 52 of the body 50 by applying electric power to the condenser, the evaporator, the compressor, the second blowing fan 26' The outside air flows into the air inlet 52 by the second blowing fan 26 ', and the temperature rises when the air passes through the heater 53.

When the temperature of the air is increased, the space inside the space is wider than the air inlet. Therefore, when the air is dispersed, the temperature is also dispersed to lower the temperature, and the lowered air is contained in the air when passing through the evaporator 25 And the condensed water is condensed.

If this method is repeated continuously, water will be continuously generated in the water producing section.

The outside air described above is cold air (approximately 10 degrees or less approximately). Since this cold air does not greatly differ from the temperature of the evaporator 25 via the vaporizer, the moisture does not condense even if moisture is contained in the air.

The present invention has the advantage of producing water for four seasons (in the case of Korea) by providing a technique of generating water by heating the cold air in the air to reach the dehumidifying device of the air water system.

The air heating device for heating the cold air has an advantage that it can be additionally installed in the air water system.

The above-mentioned effects are further clarified in the concrete contents.

Explaining the constitution corresponding to the present invention

A condenser 26 for condensing the high temperature and high pressure refrigerant gas discharged from the compressor 27 and a condenser 26 for condensing the refrigerant gas discharged from the compressor 27, Pressure refrigerant that has passed through a tube (capillary tube) that expands the refrigerant liquefied through the evaporator 25 and the condenser 26, and the outside air flows through the evaporator 25 and the water- And a connection hole 51 connected to one side of the body 50 so as to communicate with the air inlet 25 '' of the evaporator 25 through which the outside air flows, is connected to the second blowing fan 26 ' And the other side of the body 50 has an air inlet 52 through which the outside air flows and a heater part 53 accommodated in the air inlet part 52 and a heater part 53 accommodated between the connection hole 51 and the heater part 53 And a space portion 54 formed in the housing.

In the description 60 and 61, the air introduced through the air inlet is obstructed so that the air is dispersed in the space or an external shape is generated, so that the air heated by the heater can be dispersed throughout the space.

When dispersed in this way, a high temperature (about 60 degrees or more) of air heated in the heater lowers the temperature.

If the air introduced into the air inlet flows into the evaporator through the heater and the connecting hole without being dispersed, the dehumidifying efficiency may be lowered because the introduced air is at a high temperature.

Hereinafter, an embodiment will be described.

A second air blowing fan 26 ', and a heater 53 installed at a portion of the air inlet 52 of the body 50 by applying electric power to the condenser, the evaporator, the compressor, the second blowing fan 26' The outside air is introduced into the air inlet 52 through the second blowing fan 26 ', and the temperature rises when the air passes through the heater 53.

When the temperature of the air is increased, the space inside the space is wider than the air inlet. Therefore, when the air is dispersed, the temperature is also dispersed to lower the temperature, and the lowered air is contained in the air when passing through the evaporator 25 And the condensed water is condensed.

If this method is repeated continuously, water will be continuously generated in the water producing section.

The outside air described above is cold air (approximately 10 degrees or less approximately). When the cold air passes through the evaporator 25, the temperature difference between the evaporator 25 and the evaporator 25 does not significantly increase, so that moisture contained in the air is not condensed.

The following describes the control process as an example.

When external air flows into the space portion 54 by the second blowing fan 26 ', the temperature sensor 54' installed in the space portion senses the internal temperature of the space portion 54,

If the temperature value is constant, the heater 53 is continuously operated to constantly heat the air introduced from the outside. When the sensing value sensed by the temperature sensor during this heating is out of the preset value (the temperature is higher than the preset temperature ) In case of I, the electric power applied to the heater 53 is stopped or the temperature of the heater 53 is changed to lower the temperature of the heater to heat the air.

After the external cold air is heated to a predetermined temperature, water is generated by passing through the evaporator 25, the water generator 20, and the condenser 26.

The humidity sensor included in the air inlet 52 senses the humidity included in the outside air, and the controller controls the motor of the second blowing fan 26 '(BLDC motor) according to the sensed value detected through the humidity sensor It is possible to vary the number of revolutions of the outside air inflow amount.

The humidity sensor 52 'of the present invention senses a high humidity area and a low humidity area of outside air.

And adjusts the wind direction of the second blowing fan according to the case where the humidity is high and the humidity is low.

The second blowing fan can control the weak wind and the strong wind mode when discharging air.

The weak wind corresponds to a weaker blowing mode than the strong wind mode.

The reason for doing this is that if the moisture contained in the outside air is low,

In order to generate water.

The humidity sensor 52 'changes the third blowing fan 26' to strong wind if the outside air humidity is lower than the set value, and blows the blowing amount that has been set in advance when the humidity is set.

Hereinafter, a conventional configuration capable of supporting the present invention will be described.

As shown in FIGS. 4 to 5, includes an air suction unit 10, a water generating unit 20, a water purification unit 30, a purified water supply unit 40, and an air discharge unit 26 ".

The air intake part 10 is connected to a duct 13 capable of selectively collecting indoor air and outdoor air.

At this time, it is preferable that an air filter (not shown) is mounted on the air suction side of the duct 13 so as to remove foreign substances of the air to be sucked.

The water generating unit 20 is coupled to the lower portion of the air intake unit 10 so as to generate water from the air supplied through the air intake unit 10 and use it as raw water. The water generating unit 20 includes a main body 21, 22, a bulb 23, a storage portion 24, an evaporator 25, a condenser 26, and a compressor 27.

The main body 21 is provided with a receiving space therein and an upper side thereof is opened so that the lid 22 is closed on the opened upper side of the main body 21 and the air suction part 10 Is installed.

The air inlet 23 is formed to collect the water generated in the main body 21 from the air supplied through the air suction unit 10 into the storage unit 24 and has an outlet for discharging the generated water 23 'are formed.

The evaporator 25 cools the air supplied by the air suction unit 10 to below the dew point and the condenser 26 converts the hot gas refrigerant containing the heat taken in the evaporator 25 into cold refrigerated low temperature liquid refrigerant And the compressor 27 is connected to the evaporator 25 and the condenser 26 to compress the circulating gaseous refrigerant to a high temperature and a high pressure.

The purified water portion is mounted on one side of the storage portion 24 in which the water generated in the water generating portion 20 is collected so that the water supplied through the supply pump 31 can be consumed or used by using the plurality of filters 32 Filtration and purification.

The purified water supply unit (not shown) is provided to cool or heat the water supplied from the water storage tank 33 installed in the front part and stored purified water through the purified water part 30.

The air discharging portion 26 '' is installed at the rear portion and is formed to discharge the heat generated by the operation of the water generating portion 20 and the dry and warm air and the purified water supplying portion (not shown).

The operation of the first embodiment of the present invention air-water system having the above-described structure will be described.

The air sucked into the duct 13 flows into the main body 21 as the air suction part 10 operates.

The air sucked into the main body 21 is supplied to the compressor 27 for compressing the gaseous refrigerant at high temperature and high pressure and the condenser 26 for condensing the high temperature and high pressure refrigerant gas discharged from the compressor 27, And an evaporator 25 for evaporating a low-pressure refrigerant that has passed through a tube (capillary tube) that expands the refrigerant liquefied through the condenser 26. This refrigeration system is operated by the following principle Respectively.

First, the air supplied to the main body 21 by the air blowing fan (including the second fan) evaporates the low-pressure refrigerant by the evaporator 25 so that the inside of the main body 21 is cooled below the dew point due to the heat of vaporization, ) The moisture in the air flowing into the inside becomes solid state like a frost (frost).

At this time, when the power supply for operating the evaporator 25 is turned off, the liquid state of the solid state is defrosted and defrosted to generate liquid water.

As the power supplied to the evaporator 25 is periodically supplied or turned off by a timer (not shown), a temperature sensor (not shown), or the like, Water is converted from a solid state, such as an aqueous phase, to a liquid state, such as water, to produce water.

In addition, since water can be generated while supplying or shutting off the power supplied to the evaporator periodically, there is no need to continuously operate the evaporator, thereby reducing the cost cost of cooling the air.

On the other hand, the gaseous refrigerant including the heat taken from the evaporator 25 after being compressed by the compressor 27 at a high temperature and a high pressure is converted into a low-temperature liquid refrigerant cooled through the condenser 26 while the water generator 20 operates In this process, heat generated through the condenser 26 is discharged to the outside through the air discharge portion 26 ".

The water produced as described above flows down from the upper part of the main body 21 and is collected by the storage part 24 located at the discharge port 23 'side and the water collected in the storage part 24 is discharged by the supply pump 31 to the purified water part 30, and is filtered and purified through a plurality of filters 32.

The purified water purified through the water purification unit 30 is supplied to the user through the purified water supply unit 40 through the purified water supply unit 40 so that the water vapor contained in the air is condensed and the collected water is used as the raw water It can be provided as potable water that can be consumed or used.

Here, the heat generated as the purified water supply unit 40 is operated is supplied to the condenser 26

 And is discharged to the outside through the air discharge portion 26 ".

The main body 21 has a curved shape so that the condensed water flows through the evaporator 25 and is discharged to the outside through the discharge port while the condenser 26 discharges the condensed water to the outside through the condenser 26, (19).

The following section describes the control section.

When the cooling fins 25 'of the evaporator 25 are accumulated on the sidewalls of the main body 21

Even if the second blowing fan 26 'is operated, external air does not flow into the main body 21 but is evacuated into the main body 21. The suction pipe (not shown) of the vacuum sensor 38 29) is positioned inside the main body through the wall surface of the main body

When the vacuum sensor 38 is turned on due to a buildup of the cooling fin 25 'due to the operation of the freezing / cooling cycle (referred to as a refrigeration cycle), the refrigeration cycle is stopped and the second blowing fan 26' The outside air is brought into contact with water to secure water

 When the vacuum sensor 38 is opened during the removal of the sludge, the refrigeration cycle is operated until the vacuum sensor 38 is turned on by accumulating the cooling fin 25 '.

Thus, the lifetime of the freezing cycle can be significantly extended by allowing the freezing cycle to be stopped.

Since the vacuum sensor 38 is described in detail in Patent Document No. 10-1456456, the defrosting device of the heat exchanger, a description thereof will be omitted.

As a result, equipment such as a condenser is continuously operated, and the entire refrigeration system is overheated due to fatigue, so that the refrigerator can be frequently damaged.

In another configuration, the dual pressure switches 25A and 25B are installed in the gas piping corresponding to the cooling fins 25 'of the evaporator 25

(Power supplied to the refrigeration system) is turned off when the dual pressure switches 25A and 25B are out of the preset pressure value by the cooling fins 25 '

When the cooling fins 25 'are removed, the dual pressure switches 25A and 25B are set to a predetermined pressure value range

When the dual pressure switches 25A and 25B are turned off when the cooling fins 25 'are frozen due to the operation of the refrigeration cycle, the refrigeration cycle is stopped and the blowing fan 26' is continuously operated to melt water to secure water, When the dual pressure switches 25A and 25B are turned on during the removal, the refrigeration cycle is operated until the dual pressure switch 38 is turned off when the cooling pin 25 'is frozen.

The dual pressure switch is a pressure switch mainly used for stopping the refrigeration cycle if the evaporator is accumulated in the freezing facility when the freezing warehouse is constructed. The dual pressure switch is described in Patent Publication No. 1998-0009616.
