Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for recycling heavy water using an air conditioner condensate,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for recycling air conditioning condensed water, and more particularly, to a system for recycling heavy water that enables condensed water generated on the surface of an evaporator to be recycled together with heavy water.

The air conditioner is a device for sucking indoor air and discharging it to maintain indoor air in a more comfortable condition than outdoor. The air conditioner can be divided into a stand type and a ceiling type according to its structure. However, since the heat exchange process is performed between the internal air and the refrigerant gas, condensed water is generated on the surface of the evaporator.

However, the present evaporator is not provided with a separate device for collecting the condensed water generated during operation of the air conditioner.

Therefore, the present air conditioner structure is a structure in which condensed water generated on the surface of the evaporator is directly discharged to the outside. In this case, the discharge of the condensed water causes the water to float on the ground or make a puddle. As a result, it causes aquatic insects such as mosquitoes in the season of high temperature, which causes the quality of the living environment to deteriorate.

In addition, the condensed water can be recycled because the degree of contamination is relatively low, which is directly discharged to the outside, resulting in waste of resources. In other words, clean water with a relatively low level of pollution can be utilized as water for drinking, but water is not likely to come into contact with the human body. However, the water is not currently being recycled.

Of course, conventionally, a device for treating condensate of an air conditioner, that is, Korea Patent Application Publication No. 2007-0028885 (Mar. 13, 2007, condensate water treatment device of integrated air conditioner. The prior art document discloses a configuration in which condensed water is collected and discharged through a flow path to treat the condensed water.

However, the prior art only discloses a configuration for discharging only condensed water to the outside, and there is no mention of a configuration for recycling the condensed water as described above.

Korean Patent Publication No. 2007-0028885 (Mar. 13, 2007) Condensate Treatment Apparatus for Integrated Air Conditioner

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 minimize the damage caused by the air conditioner condensed water falling on the surface of the evaporator.

Another object of the present invention is to enable efficient use of water resources by allowing air conditioning condensate to be reused together with heavy water.

According to an aspect of the present invention, there is provided an evaporator comprising: an evaporator; A drain for collecting condensed water formed on an outer surface of the evaporator in accordance with driving of the air conditioner; A storage tank for storing the condensed water collected in the drain and the heavy water supplied from the heavy water system; And a drain pipe formed in the storage tank and discharging the heavy water to the outside together with the condensed water.

The drain and the storage tank are connected to a drain pipe, and the drain pipe further comprises a drain pump.

The drain includes a body forming an inner space to collect the condensed water. The bottom surface of the body is formed into an inclined surface shape or a funnel shape that tilts to one side so that the condensed water is supplied to the drain tube, On the inner surface of the body, a contact holder having a magnetic body is formed to protrude.

The contact holder may be formed of an elastic material or may be formed by providing an elastic body therein so that the protruding thickness of the contact holder becomes thin when the evaporator is coupled with the evaporator.

According to another aspect of the present invention, there is provided an air conditioner comprising: a first drain coupled to an evaporator of a roof type air conditioner; A second drain coupled to the evaporator of the stand-type air conditioner; A first valve mounted on a first drain pipe connected to the first drain; A drain pump mounted on a second drain pipe connected to the second drain; A storage tank connected to the first drain pipe and the second drain pipe and connected to the heavy water system through a water pipe; A second valve mounted on the water supply pipe; A drain pipe for draining the heavy water stored in the storage tank to the outside; A sensor for sensing the level of the first drain, the second drain, and the storage tank; And a controller for controlling at least one of the first valve, the second valve, the drain pipe, and the drain pump according to the detection result of the sensor.

The control unit cuts off the supply of the condensed water and the heavy water when the water level of the storage tank reaches a predetermined water level.

The control unit forcibly opens the drain pipe in accordance with the level of the storage tank.

The heavy water recycling system using the air conditioning condensed water according to the present invention has the following effects.

That is, the condensed water formed on the outer surface of the air conditioner evaporator can be directly dropped to the bottom, preventing the ground surface from sinking, and also preventing the condensed water from accumulating in the puddle or ground. Therefore, it is possible to prevent the occurrence of aquatic pests such as mosquitoes in the season when the temperature is high as in the summer, and the living environment around the air conditioner can be improved.

Also, since condensate can be recycled with heavy water, cost savings can be achieved compared to using only heavy water. This can be expected to result in greater savings than using only tap water for various living water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a heavy water recycling system using an air conditioner condensed water according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a configuration diagram of a heavy water recycling system apparatus using an air conditioner condensed water according to a preferred embodiment of the present invention.

As shown in FIG. 1, the heavy water recycling system apparatus 100 is provided with a plurality of air conditioners 110 and 120. The air conditioner is applied to both the ceiling type air conditioner 110 and the stand type air conditioner 120 according to its structure.

The air conditioners 110 and 120 are provided with an evaporator 130. For reference, the evaporator 130 is required for both the ceiling-type air conditioner and the stand-type air conditioner, but only the ceiling-type air conditioner will be described in the embodiment. The evaporator 130 absorbs the thermal energy of the air and serves to exchange heat between the refrigerant gas and the air. That is, the evaporator 130 is a cooling device that makes hot air pass through to cool it, and usually has a thin metal plate structure with a cooling catalyst inside. In the present embodiment, the internal structure of the air conditioner will not be described. That is, the air conditioner is a general public technology, and the present embodiment is to process only the condensed water generated on the surface of the evaporator 130. Here, condensate refers to water droplets generated on the surface of the evaporator when the air conditioner is driven.

A drain (140) for collecting condensed water is mounted for each evaporator (130). The drain 140 is also shown only in the ceiling type air conditioner 110 in the figure. The drain 140 has a structure that is integrally fixed to the evaporator 130 or detachably attached thereto. In addition, the outer shape can be any shape that can be installed on the lower portion of the evaporator 130 and collect the condensed water falling from the evaporator 130. The structure of the drain 140 will be described later.

Subsequently, at least one drain pipe (150) (160) is connected to the drain (140). The drain pipes 150 and 160 serve to form a flow path so that the condensed water collected in the drain 140 flows.

Meanwhile, each of the drain pipes 150 connected to the ceiling type air conditioner 110 must be connected to one another. And one drain pipe 160 connected to the stand-type air conditioner 120. This will be referred to as a first drain pipe unit 152 and a second drain pipe unit 162.

A drain pump 170 is mounted on the second drain pipe unit 162. The drain pump 170 may be installed only in the drain pipe unit 162 connected to the stand-type air conditioner 120 as shown in FIG. That is, in the case of the ceiling type air conditioner 110, the condensed water can be easily discharged to the drain pipe unit 162 by the operation of an automatic drain pump (not shown) attached to the side of the heat exchanger inside the air conditioner.

And can be easily discharged downward by gravity.

A storage tank 180 for storing condensed water supplied through the first drain pipe unit 152 and the second drain pipe unit 162 is constructed. At this time, the storage tank 180 functions as a heavy water tank that receives the purified water purified from the sewage in addition to the condensed water through the water pipe 182. That is, the water supply pipe 182 is connected to a heavy water system (not shown). The heavy water system refers to a system that purifies and recycles various wastewater such as domestic sewage and kitchen sewage with relatively low pollution by a certain purification treatment. The heavy water supplied by such a heavy water system is usually used for flush toilet water, cooling water, sprinkling water, industrial water, agricultural water, landscape water and the like.

A drain pipe 190 is connected to the storage tank 180. The drain pipe 190 is a pipe for supplying heavy water mixed with condensed water so that it can be used as various kinds of water as described above. A plurality of drain pipes 190 may be installed.

FIG. 2 is a perspective view showing a drain structure provided on the lower side of the evaporator in FIG. 1, FIG. 3 is a side view showing an inner side surface of the drain structure of FIG. 2, and FIG. 4 is a sectional view taken along line I-I 'of FIG.

Referring to these drawings, the drain 140 is formed with a body 144 which forms a space 142 inside the condenser so as to collect condensate of the evaporator. That is, the body 144 forms the external shape and skeleton of the drain 140. At this time, it is preferable that the bottom portion of the body 144 is formed in a funnel shape so that the condensed water can flow smoothly in one direction or can be flowed to the center of the bottom surface.

A connection port 145 is formed at one side of the drain 140 to connect the drain pipes 150 and 160. One or more connection ports 145 may be formed. Therefore, when there are two connection ports 145, the drain pipes 150 and 160 should be connected to each other.

The drain 140 is provided with a connecting means for connection with the evaporator. Examples of the connecting means may be a magnetic body, a connecting ring, or the like. For example, a magnetic body may be formed on the inner surface of the drain 140, and the magnetic body may be coupled to the evaporator by the magnetism of the magnetic body. At this time, the magnetic substance may be formed to be exposed on the inner surface of the drain 140, but it may be provided inside and formed with a separate contact holder.

Examples in which a contact holder is disclosed are shown in Figs. 3 and 4. Fig.

That is, when the contact holder 146 is formed, the contact holder 146 is formed to have a predetermined thickness protruding from the inner side surface of the drain 140. The contact holder 146 itself may be formed of an elastic material, have. Then, a magnetic body 147 is formed inside. Thus, when the drain 140 is coupled to the outer surface of the evaporator 130, the contact force between the contact holder 146 and the evaporator 130 can be increased. At this time, when the outer surface of the evaporator 130 can not provide magnetism, a magnetic body or the like should be mounted on the outer surface of the evaporator 130.

On the other hand, the structure of the drain 140 coupled with the evaporator 130 is only one embodiment. In other words, as described above, the evaporator 130 can collect all the condensed water.

The condensed water collected in the drain 140 is supplied to the storage tank 180 through the first drain pipe unit 152 and the second drain pipe unit 162. Also, heavy water is supplied from the heavy water system through the water supply pipe 182 connected to the storage tank 180.

Then, the heavy water stored in the storage tank 180 is supplied with the desired use water through the water pipe 190 as needed.

In the present invention, the quantity of the heavy water stored in the storage tank always maintains the optimum line, which can provide a possible embodiment by adjusting the supply amount of the condensed water or the heavy water. This will be described in detail with reference to FIG.

5 is a block diagram illustrating a heavy water recycling system according to another embodiment of the present invention. Hereinafter, in describing the configuration of FIG. 5, the heavy water recycling system apparatus has substantially the same structure as that of FIG. 1, and therefore, a description thereof will be omitted. However, the operation performed according to the detection result of the sensor will be mainly described.

As shown in FIG. 5, the heavy water recycling system 200 includes drains 210 and 220. Here, reference numeral 210 denotes a first drain mounted on the ceiling-mounted air conditioner, and reference numeral 220 denotes a second drain mounted on the stand-type air conditioner. At this time, inside the drains 210 and 220, a first sensor 212 and a second sensor 222 are configured as sensors for detecting the level of water.

Drain pipes 230 and 240 are connected to the first drain 210 and the second drain 220, respectively. The drain pipe is also divided into a first drain pipe (230) and a second drain pipe (240). The first drain pipe 230 is connected to the first drain 210 and the second drain pipe 240 is connected to the second drain 220.

A drain pump 250 is installed in the flow path of the second drain pipe 240.

A storage tank 260 is connected to the first drain pipe 230 and the second drain pipe 240. The storage tank 260 is connected to a heavy water system 270 through a water supply pipe 262.

On the other hand, the first drain pipe 230 and the water supply pipe 262 are provided with a drain pipe opening / closing valve (first valve) 232 and a water supply pipe opening / closing valve (second valve) Condensate water or heavy water is supplied to or blocked from the storage tank 260 as the opening and closing valves 232 and 264 are opened and closed. At this time, a water level sensing sensor (third sensor) 266 is formed inside the storage tank 260.

A control unit 280 for controlling the opening and closing operations of the first valve 232 and the second valve 264 and the operation of the drain pump 250 is configured. This can be performed by sensing the water level in the drains 210 and 220 and the storage tank 260. The control unit 280 may be included in the heavy water system 270 or may be separately configured. If configured in the heavy water system 270, it is desirable to design the function to be added to a control unit (microprocessor) that controls the heavy water system 270.

The operation of another embodiment of the present invention thus configured will be described.

The first sensor 212 and the second sensor 222 mounted on the drains 210 and 220 and the third sensor 266 of the storage tank 260 continue to transmit the level sensing signal to the control unit 280 .

According to the detection signal, the controller 280 performs the following operation.

First, the quantity of the storage tank 260 has reached a proper quantity.

At this time, it is necessary to block the supply of heavy water and condensate to the storage tank 260. Accordingly, the controller 280 causes the first valve 232 and the second valve 264 to be closed. Further, the drain pump 250 maintains the undriven state.

In the meantime, if the heavy water stored in the storage tank 260 is not drained through the drain pipe, the condensed water collected in the first drain 210 and the second drain 220 will be continuously collected. In some cases, the condensed water may overflow the first drain 210 and the second drain 220.

When the condensed water is collected in the first drain 210 and the second drain 220 and exceeds the proper level in a state where the heavy water in the storage tank 260 is not drained, the controller 280 controls the first valve 232, And at the same time the drain pump 250 is driven. At this time, it is natural that only one of the first valve 232 and the drain pump 250 is operated so that only one of the drains exceeds the proper level. The condensed water will be supplied to the storage tank 260 and the water level of the first drain 210 and the second drain 220 will be lowered. While the water level of the storage tank 260 rises. When the water level of the storage tank 260 continuously increases, the control unit 280 forcibly opens the drain pipe so that the heavy water is drained. In this case, it is preferable to supply the water with a water which does not affect the life even if heavy water is forcibly supplied according to the predetermined order.

On the other hand, the operation of the air conditioner may be forcibly stopped so that the condensed water collected in the drains 210 and 220 does not overflow without forcibly opening the drain pipe. Of course, this is just one example. That is, in a place where the air conditioner is to be always operated, a drain pipe may be formed on the upper side of the storage tank 260 for adjusting the water level of the storage tank 260 so that a part of the water can be discharged to the outside.

Next, it is the case that the quantity of the storage tank 260 has not reached the proper quantity.

At this time, the controller 280 opens the first valve 232 and the second valve 264 so that the condensed water collected in the first drain 210 and the heavy water are supplied from the heavy water system 270 together. Also, the drain pump 250 is driven to supply the condensed water collected in the second drain 220.

When the water level of the storage tank 260 reaches an appropriate water level according to the supply of the condensed water and the heavy water, the controller 280 controls at least one of the first valve 232, the second valve 264, and the drain pump 280 And performs a control operation on the configuration.

The supply of the condensed water and the heavy water is interrupted, and the quantity of the storage tank 260 is appropriately maintained.

Meanwhile, various control operations are possible in addition to the operations according to the above-described embodiments.

For example, when the air conditioner is not operated, the control unit 280 can take charge of only opening and closing of the second valve 264 in accordance with the connection operation with the heavy water system 270.

As described above, the present embodiment provides a technical point that a recycling apparatus is configured to collect condensed water formed on an outer surface of an air conditioner and recycle it together with heavy water.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
