Description

Underwater heat exchanger system using water flow and water heat and its construction method {UNDERWATER HEAT EXCHANGER SYSTEM USING WATER CURRENT AND WATER HEAT AND METHOD FOR CONSTRUCTING THIS SAME}

The present invention relates to a heat pump installed in a lake or reservoir or sea to use water flow and water heat, and more specifically, to install an underwater heat exchanger (underwater heat exchange coil tube) in water, such as sea water, and a circulation pump to the ground or water. The present invention relates to an underwater heat exchanger system using water flow and water heat for heating and cooling a building or aquaculture facility using circulation of circulating water (Brine) without using direct circulation of water such as sea water by installing a heat exchanger.

This part provides background information related to the contents of the present application, but is not necessarily prior art.

 Among the heat pump systems installed in conventional appeals, reservoirs, rivers, and seas to operate water heat, the shape of the underwater heat exchanger is in the form of a circular coiled tube underwater to maximize the area of the heat exchanger within a limited unit area. It was often installed on.

Here, it can be said that the shape of the heat exchange coil tube can be maintained in the case of a reservoir or a reservoir with little movement of water flow, but in the case of a river or the sea, the flow velocity of a stream or the tidal current in the sea Due to the influence of the ocean current at the depth of the water or the depth of water, there was a technical limit to maintain the shape of the heat exchange coil tube.

Moreover, when the heat exchange coil tube is a tube made of high-density polyethylene (HDPE), the specific gravity or density does not reach 0.93 ~ 0.97, so the entire heat exchange coil tube installed due to the rise of the heat exchange coil tube due to buoyancy due to the difference in specific gravity is streamed. There was also a problem that it was difficult to keep it fixed to the bottom or the bottom.

Moreover, in order to secure the heat exchange capacity, it is necessary to secure a sufficient length of the heat exchange coil tube in order to secure the heat transfer area of the heat exchange coil tube, so the installation volume of the heat exchange coil tube has to be increased, and the installation area naturally also has to be widened. This had a problem that more cost and time were required to maintain the facility after installation.

It is difficult to solve these problems, and the heat pump system, which is composed of an underwater sealed heat exchange coil tube using a heat exchange coil tube, has limitations in constructing a large-capacity system, so it cannot be used.

For this reason, a general hydrothermal heat pump system configured to pass river water, lake water, or sea water directly through the heat pump heat exchanger in the machine room is being widely operated.

However, in such a system, various moss, algae, or seaweeds inhabiting river water, lake water, or seawater are inhabited by water pipes or heat exchangers, causing contamination, while blocking strainers of this circulating water system such as straw, seaweed, floating water and barnacles. In addition, there was a high problem that could cause an accident of clogging the heat exchanger of the heat pump, and the maintenance cost after the facility was greatly increased.

In particular, in the case of a heat pump system that directly heats the sea water and heats it, corrosion progress of the device by chlorine in the sea water is a serious problem, and it is recognized as a large factor that determines the stable operation and durability of the system. In the case of selection, the heat exchanger, in particular, had a problem of not being able to significantly meet the necessity of a site requiring economical facilities by using expensive corrosion-resistant titanium material or piping material using stainless 316 series.

In addition, when circulating water or river water or sea water directly and circulating it to the heat exchanger on the ground, the circulating circulating water is circulated through the heat exchanger and then designed and operated as a system that is discharged to a lake, river, or sea. High power is required to lift the water required for the circulation of the water, which increases the operation and maintenance costs of the facility, which lowers the economic efficiency.In the low tide period when the water level decreases or during the low tide when the water level decreases, the circulation lift becomes higher. There was a problem that the cost of the circulating power became higher.

In the case of the circulating water circulating system, the circulating pump generally uses an underwater circulating pump in the case of small and medium-sized water, and the circulating water pump is maintained for maintenance in the event of a motor failure due to water leakage or an obstruction failure due to suspended solids. In management, it was inevitable that maintenance was inconvenient by lifting and repairing in water, and maintenance costs were also relatively expensive compared to the ground.

The present invention is to solve the problems as described above, while installing an underwater heat exchanger under the sea surface of a lake, a river, or the sea, a circulation pump and a heat exchanger are installed on the water phase (ground) and heat is recovered using circulation of the brine. After that, the purpose is to provide an underwater heat exchanger system and its construction method using water flow and water heat to solve problems caused by sea water by supplying it to buildings or aquaculture facilities.

An underwater heat exchanger system using water flow and water heat according to the present invention includes: a sealed underwater heat exchange coil tube installed in water so as to take advantage of the characteristics of rapid movement of seawater exchanged through a water flow formed by algae or ocean currents; A circulation pump circulating circulating water in the underwater heat exchange coil tube; An underwater fixing means that suppresses the floating of the underwater heat exchange coil pipe by buoyancy or maintains the position of the underwater heat exchange coil pipe through fixing of the underwater floor; A heat exchanger to recover heat of the circulating water; The heat exchanger includes a load that uses heat recovered as a heat source, and the underwater heat exchange coil tube is submerged in water to recover heat from water in the water through circulating water, and the circulation pump and heat exchanger are installed so as not to be submerged in water While being connected to the underwater heat exchange coil pipe, whereby the circulation water is circulated through the heat exchange coil pipe by the operation of the circulation pump to recover heat from the water in the water and then circulate the heat exchanger of the water phase to supply to the load It is characterized by.

According to the underwater heat exchanger system using the water flow and water heat according to the present invention and a construction method thereof, an underwater heat exchanger is installed below the sea surface of a lake, a river, or the sea while a circulation pump and a heat exchanger are installed on the water surface (ground) and the brine is circulated. It is effective to prevent contamination and damage of the circulation pump and heat exchanger generated during the direct pumping of sea water by recovering heat using it and supplying it to a building or aquaculture facility, and also maintains it through the use of an on-shore circulation pump. Not only is it easy to repair, it also eliminates the high suction or discharge head formed by the difference between the tides, and the operation is very economical and convenient due to the economical cost of the power formed by simply circulating the head. Due to this effect, the heat exchange capacity can be significantly expanded to a large capacity compared to the conventional seawater pumping heat exchange system, and thus, it can be utilized in a cooling heat exchange system during general industrial facility processes.

It is a method of recovering and using the heat of water through circulating water without directly pumping, while the underwater heat exchange coil tube 10 is an underwater installation method that is submerged in water, whereas the circulation pump 20 and the heat exchanger 30 are water (land, It is installed in a separate water structure, etc., and for this purpose, the underwater heat exchange coil tube 10 is settled on the seabed while the underwater heat exchange coil tube 10 is prevented from being floated by buoyancy. Anchor 50 that does not move by, and includes a buoy 60 that informs the position of the underwater heat exchange coil tube 10 or adds a floating force. In addition, a series of basic components that the normal vertically sealed geothermal system is equipped, that is, the replenishment water tank 21 and the expansion tank 22 constituted in each heat exchange coil tube 10 and the heat exchanger 30 are similar. Will be installed and operated.

1. Underwater heat exchange coil tube.

The underwater heat exchange coil tube 10 is composed of a plurality of heat exchange tubes 11, a front end header 12 connected to one side of the heat exchange tubes 11, and a rear end header 13 connected to the other side of the heat exchange tube 11, , The front end header 12 is connected to the supply pipe 31 as the supply side of the heat exchanger 30 while the rear end header 13 is connected to the return pipe 32 as the return side of the heat exchanger 30, that is, heat exchange A circulation loop in the form of a closed loop is provided along with the base 30, and of course, a circulation pump 20 is installed in the circulation path. This form of the collective bundle pipe has an advantage that it can be efficiently used in a narrow space. The heat exchange tubes 11 are tubular with one side and the other side open, and are connected to the watertightness to the front header 12 and the rear header 13, respectively.

For example, the heat exchange tube 11 and the front and rear end headers 12 and 13 are made of HDPE material to be coupled by mutual heat fusion, thereby ensuring water resistance while having corrosion resistance (less risk of leakage), and FIG. 2 and FIG. As shown in Fig. 3, a fusion socket 12a is formed in the front end header 12, and the heat exchange tube 11 is inserted into the fusion socket 12a and connected by fusion.

Of course, it is also possible to combine the valve socket to the front and rear end headers 12 and 13, and to unionly screw the heat exchange tube 11 to the valve socket, and provide the material of the front and rear end headers 12 and 13 and the heat exchange tube 11. It would be possible to use a corrosive metal material to join through welding.

On the other hand, if a partial leak or damage occurs in the underwater heat exchange coil tube 10, a check valve V1 may be configured for inspection and repair.

The check valve (V1) is a heat exchanger coil installed separately through a supply pipe (31) or a return pipe (32) on the front and rear end headers (12, 13) side to which the underwater heat exchange coil pipe (10) is coupled, or a combination thereof. It is installed in the main pipe installed in the group (10), and in case of partial leakage or breakage, only the relevant heat exchange coil tube (10) group is blocked to perform repairs, and other heat exchange coil tube (10) groups allow normal operation. .

The underwater heat exchange coil tube 10 may include a partition baffle 16 as an additional configuration.

The partition baffle 16 is a heat exchange tube to prevent malfunction or damage due to coral interference or friction due to sagging phenomenon in the water when the length of the heat exchange tube 11 between the front and rear headers 12 and 13 is increased. 11) is to be kept at regular intervals, and the shape can be variously configured, such as plate shape and ring shape.

The front end header 12 and the rear end header 13 are capable of various structures capable of collecting and distributing circulating water, for example, a closed cylinder structure is possible, and the front end header 12 is supplied with a supply pipe 31. A port 14 is formed, and a return port 15 connected to the return pipe 32 is formed in the rear end header 13.

Here, as shown in FIG. 1, when a plurality of underwater heat exchange coil tubes 10 are used in series, neighboring underwater heat exchange coil tubes 10 are connected to each other through a return port 15 and a supply port 14 will be.

In the case of the cylinder structure, as shown in FIG. 6, the front end header 12 includes a portion 12-1 (plate-like) to which the heat exchange tube 11 is coupled and a portion 12-2 having a port 14 (concave space) It is possible to manufacture in a form of combining two (structure having a chamber inside) after dividing it into a possible form).

 2 and 3 show an example in which the front end header 12 and the rear end header 13 are in the form of a circular ring, and the underwater heat exchange coil tube 10 in the ring form is formed of water through an empty space inside. It has the advantage of taking less resistance.

The front header 12 and the rear header 13 are classified based on the installation state, and are products of the same type.

4 and 5 show an example in which the front and rear end headers 12 and 13 are formed in a straight cylindrical shape, and a plurality of heat exchange tubes 11 are arranged in a row between the rectangular front and rear end headers 12 and 13. (FIG. 4) or two rows (FIG. 5) or more are arranged and combined.

The plurality of underwater heat exchange coil tubes 10 may be both in series and in parallel, and FIG. 1 shows an example of series and FIG. 7 shows an example of parallel.

In the case of the series, the plurality of underwater heat exchange coil tubes 10 are connected to each other by returning ports 15 and supply ports 14 in series, and the supply ports of the underwater heat exchange coil tubes 10 closest to the heat exchanger 30 side. While 14 is connected to the supply pipe 31, the return port 15 of the last underwater heat exchange coil pipe 10 is connected to the return pipe 32.

In the case of parallel, a plurality of underwater heat exchange coil pipes 10 and a supply manifold 33 and a return manifold 34 connected to the supply pipe 31 or the return pipe 32 are additionally configured.

Between the supply manifold 33 and the return manifold 34, two or more rows of underwater heat exchange coil pipes 10 are arranged so that one side and the other side are connected to the supply manifold 33 and the return manifold 34, respectively. Connected. Two or more underwater heat exchange coil tubes 10 between the supply manifold 33 and the return manifold 34 are arranged in series.

The heat exchange tube 11 of the underwater heat exchange coil tube 10 is not limited to a straight line, and may be wound in a coil form as shown in FIGS. 8 and 9.

In the coil-type heat exchange tube 11, two or more lines can be arranged in parallel between the front and rear headers 12 and 13, and neighboring ones are fixed through the fixture 16 so that they are not tangled. The coil-type heat exchange tube 11 may also be configured by setting two lines connected through the spacer 17 to one set.

At this time, the load add-on 40 may be installed by hanging through a connection line to the coil-shaped heat exchange tube 11, a plurality of which are disposed at the bottom, and also, a rope fixed to the front and rear headers 12, 13 43).

23 and 24, the front and rear headers 12 and 13 of the underwater heat exchange coil tube 10 may also include protective layers 12a and 13a made of concrete.

The protective layers 12a and 13a of concrete are placed on the periphery of the front and rear end headers 12 and 13.

Since the protective layers 12a and 13a of concrete add a load, it can be understood as the same concept as the load adder.

On the other hand, by installing a circulation pressure sensor (PS1) in the heat exchange coil tube 10 in order to monitor the leakage due to the partial damage due to the physical environment change of the subsea part where the underwater heat exchange coil tube 10 is installed, the circulation pressure below a certain pressure When it descends, it is possible to automatically stop the heat exchanger (30).

In addition, a flow detection means 22 (flow sensor, flow meter, etc.) is installed in the replenishment water pipe supplied to the recirculating brine replenishment water tank 21 to determine an abnormality based on the replenishment amount of replenishment water, for example When a sensor is installed for a certain period of time by installing a flow sensor, or if an excessive replenishment water is replenished within a certain period by installing a flow meter, an abnormal signal is sent to the operator and the system and inspection and maintenance can be performed to prepare for a leak. .

2. Circulation pump.

The circulation pump 20 continuously circulates the circulating water in a circulation path formed by the underwater heat exchange coil tube 10 and the heat exchanger 30, and is not submerged directly in water, so it is not submerged in water (water, structure, barge) Etc.).

3. Heat exchanger.

In the case of a heat pump heat exchanger, the heat exchanger 30 is a well-known product that includes a compressor, a heat source-side two heat exchanger, a load-side heat exchanger, and an expansion valve (including four-way valves).

The heat exchanger 30 refers to a form having a known heat exchange function, such as a shell-and-tube type or a plate type heat exchanger, as a typical industrial heat exchanger.

The heat source side heat exchanger is connected to the supply pipe 31 and the return pipe 32 to exchange heat between the heat medium and the circulating water therein.

The load-side heat exchanger supplies heat of the circulating water recovered through the heat-source-side heat exchanger to the load-side heat exchanger (1) and is configured together with a circulation pipe (2) and a circulation pump (3) to circulate the load-side heat medium.

The supply pipe 31 and the return pipe 32 are respectively connected to the supply and return ports of the heat source side heat exchanger of the heat exchanger 30 and the supply port 14 and the return port 15 of the underwater heat exchange coil tube 10, respectively. One circulation water circulation path is formed, and the underwater heat exchange coil pipe 10 is placed in the water, and the circulation pump 20 and the heat exchanger 30 are disposed on the ground or on the water, so they are piped over the water and the water.

In addition, the supply pipe 31 and the return pipe 32, which are installed exposed to the sea level, prevent the phenomenon of being heated by the atmosphere or sunlight, as well as to protect the pipe from external shocks, made of urethane foam or styrofoam between the pipe and the pipe. It is assumed to take the form of a conventional double pipe heat insulating pipe that is filled.

On the other hand, in the case of a heat exchanger operating a heat pump, the heat pump uses a turbo chiller, so that a high COP can be operated.

In addition, to prevent the pipes exposed to the upper surface of the water from being damaged or moved due to waves or external impacts, a fixed bracket is constructed along the shoreline to the ground.

The supply pipe 31 and the return pipe 32 are not limited to the pipe shape shown in the drawings, and the return pipe 32 may be buried under the sea floor as shown in FIG. 10. In this case, the return pipe 32 is settled on the seabed, which also has the advantage of serving as an anchor.

4. Underwater fixing means and load add-on.

The load adding body 40 among the underwater fixing means prevents the underwater heat exchange coil pipe 10 from being floated by buoyancy and, on the other hand, shakes even if the rough wind at the sea level affects the depth of the underwater heat exchange coil pipe 10 installed. It is a heavy weight installed to prevent the damage (high specific gravity, for example, various materials such as lead, iron, and concrete are possible), and even if there is a rough storm at sea level, the blue movement becomes extremely weak when the depth of water is deep. Even though it has a weakened movement, the repeated movement in the long term may prevent leakage of circulating water brine due to the puncture of the underwater heat exchange coil tube 10 due to wear at the friction portion, and prevent it in advance and fix the position. .

The underwater heat exchange coil pipe 10 is not limited to being installed on the underwater floor, and can be installed underwater between the water surface and the underwater floor. Therefore, the load-addition body 40 goes to the underwater heat exchange coil pipe 10 to the underwater floor. It is not limited to sitting, but to maintain the installation position of the underwater heat exchange coil tube 10 underwater.

The installation position of the load adding body 40 is, for example, the supply port 14 of the underwater heat exchange coil pipe 10 and the circumference of the return port 15, as shown in FIG. 10, the supply pipe 31 and the return pipe ( It is the periphery of 32), and various shapes (ring shape, hexahedron shape, etc.) are possible depending on the installation location.

As shown in Fig. 11, when the load-addition body 40 is concrete, a hexahedral shape is preferable and is formed by forming a separate ring 41 (both lifting and connecting functions) to be used in connection with the underwater heat exchange coil tube 10 or the like. Can be. Anti-corrosive agents may be applied to the concrete body to prevent changes in concrete properties due to salt intrusion.

In addition, as shown in FIG. 12, it is also possible to increase the load by stacking a plurality of load-bearing bodies 40 of concrete in a small size for easy transportation and stacking them in a construction site. At this time, a configuration for containing or stacking the load-addition body 40 is required, and in the present invention, the load-adding of the protection guide 70 while adding a protection guide 70 for protecting the underwater heat exchange coil tube 10 is added. It will be described as an example to use as an installation space of the sieve 40.

The load adding body 40 includes a stacking hole 42 penetrating up and down, and the protection guide 70 includes a stacking rod 71 into which the stacking hole 42 is fitted, that is, the protection guide 70 The load-addition body 40 is stacked by fitting the stacking holes 41 of the load-addition body 40 to the stacked rods 71 of FIG.

The underwater trench piping connecting the heat exchange coil pipe 10 is such that a pipe is formed in the concrete cylinder, but the concrete cylinder is divided up and down so that it can be covered and fixed at the top after installing the pipe so that the heat exchange coil pipe 10 is not injured. It might be.

The load adder 40 described so far is a precast concrete method, and in another method of concrete, the load adder 40 in a cast-in-place method is also possible.

As shown in Figure 13, the protective guide 70 is provided with a formwork 72 for concrete pouring of the load-added body 40, the concrete pouring equipment 200 (mixer, pump, pouring hose, etc.) barge After being placed on the water phase, concrete is poured into the formwork 72 at the water site to form the load add-on 40.

The formwork 72 is opened so that only the part connected to the pouring hose of the concrete placing equipment 200 is opened so that the concrete does not leak to the outside during the process in which the underwater heat exchange coil tube 10 is submerged in water or sinking from the surface to the water. It is desirable to do.

The load adder 40 serves as an anchor 50 by preventing injury as well as preventing the underwater heat exchange coil tube 10 from being moved by a water flow.

5. Protection guide.

The protection guide 70 among the underwater settling means is to prevent damage from being generated while the underwater heat exchange coil pipe 10 is dragged to the bottom of a river or seabed, and the front and rear headers 12 of the underwater heat exchange coil pipe 10, It is formed over 13) to protect both the front and rear headers 12 and 13 and the heat exchange tubes 11 between them, and also functions to maintain the linearity of the heat exchange tubes 11.

The protection guide 70 should be configured such that water circulates around the underwater heat exchange coil tube 10, for example, a lattice-type container structure, a tubular structure having pores (see FIGS. 14 and 15), and , Regardless of the structure, the protection guide 70 is configured to receive one or more underwater heat exchange coil tubes 10.

Of course, the same effect can be realized by manufacturing a steel structure type protection guide such as a hot-dip galvanized H beam and installing the heat exchange coil tube 10 therein to allow it to settle in water.

For example, the protection guide 70 is a pillar type, and a pillar 70-1 fixed by excavating a seabed surface is installed, and the installation of the underwater heat exchange coil pipe 10 is stably performed using the pillar 70-1. You can also configure it.

The surroundings of the protection guide 70 are made to surround the surroundings with a net or a wire netting to prevent the floating water or seaweeds from being laminated on the heat exchange coil tube 10.

In addition, the underwater camera 800 is to be installed around the protection guide 70 to monitor and check the situation.

The protection guide 70 is preferably made of stainless material, PE material, or the like.

The protection guide 70 is configured to protect all the underwater heat exchange coil tubes 10 or can be configured to protect a single underwater heat exchange coil tube 10, and in the former case, the connection of the underwater heat exchange coil tubes 10 is also protected. If possible and in the latter case, an additional protective configuration is needed to protect the connections of the underwater heat exchange coil tubes 10, for example, as shown in FIG. 16, the connection connecting the protection guides 70 between the protection guides 70 The member 73 can be configured. The connecting member 73 may be a rod, an angle, a rope, etc., which are connected to the protection guides 70 on both sides of the longitudinal direction. In the case of the rope, there is a property of bending and flexibility, and there may be shaking of the protection guide 70 due to this, so that the length can be adjusted by a turnbuckle to compensate for this. The protection guide 70 maintains the longitudinal direction and shape of the heat exchange coil tube 10, and has a function of preventing an accident of leaking the brine due to the connection part being removed from shaking or shock.

In addition, in order to prevent a partial injury or tangling of the heat exchange coil tube 100 in water, a configuration may be possible to protect the heat exchange coil tube 10 by covering a net.

6. Anchor.

The anchor 50 of the underwater fixing means is connected to various places such as the underwater heat exchange coil tube 10 and is settled on the bottom of the sea so that the underwater heat exchange coil tube 10 does not move by water flow, and in this regard, the underwater heat exchange coil tube ( Since the injury prevention function of 10) is also possible, it is also possible to view it in the same concept as the load-adding body 40.

That is, the load adding body 40 and the anchor 50 are underwater fixing means of the underwater heat exchange coil tube 10.

7. Buoy.

The buoy 60 is installed so that the installation position of the underwater heat exchange coil pipe 10 installed on the bottom of the water or on the bottom of the sea or on the seabed can be confirmed from the upper surface of the water. 10) It is also included to maintain a constant buoyancy so as not to damage and to allow the underwater heat exchange coil pipe 10 to be located at a certain depth in the water, especially when the load adder 40 is configured.

In addition, even when the heat exchange coil tube 10 is installed under the sea level to operate in a floating form, a large amount of buoys are combined to be installed so that the heat exchange coil tube 10 is constantly submerged in water. To do.

In this case, it is possible to adjust so that the underwater heat exchange coil tube 10 does not come into contact with the underwater floor in consideration of the depth variation due to the difference between tidal waves.

In addition, an LED lamp may be configured to enhance night visibility.

8. Buoyancy tank.

As shown in FIG. 17, the present invention may also constitute an expansion buoyancy tank 80 of, for example, a separate expansion tube in the protection guide 70 of the underwater heat exchange coil tube 10.

The expansion buoyancy tank 80 is easily repaired through lifting and lifting in the event of damage or leakage of the underwater heat exchange coil tube 10, or sediments, moss, algae, barnacles, etc. are attached to the outside of the underwater heat exchange coil tube 10 underwater. It is a configuration to lift and lift the upper portion of the sea level to facilitate cleaning to prevent the heat exchange efficiency of the heat exchange coil pipe 10 from deteriorating. Meanwhile, the underwater heat exchange coil pipe 10 is placed above the water surface by adjusting buoyancy. It is also possible to float or immerse yourself in the water from the surface.

The expansion type buoyancy tank 80 is preferably installed over the bottom and perimeter of the underwater heat exchange coil tube 10.

The expansion type buoyancy tank 80 is configured with piping or the like to enable control of buoyancy (injection and discharge of compressed air, for example, as a buoyancy material) in the water or on the ground.

9. Heat storage tank.

As shown in FIG. 18, when the time zone for operating the heat pump system and the time zone for use on the heat load side are different, a separate heat storage tank 4 is used to appropriately reduce the capacity of the heat exchanger 30 and the underwater heat exchange coil tube 10. It can also be configured.

The heat storage tank 4 is connected to the heat exchanger 30 through a circulation pipe 5 and a circulation pump 6 to heat or cool the heat produced by the heat exchanger 30, and circulates with the load-side heat exchanger 1 It is connected through a pipe (2) and a circulation pump (3).

The heat exchanger 30 is operated to accumulate cold or warm heat in the heat storage tank 4 and to supply heat stored in the heat storage tank 4 to the load side during the time when the load is concentrated.

In particular, when the amount of heat exchanged in the heat exchanger (30) of a building or aquaculture facility on the ground in a water tank that does not form a water flow formed between the low tide and the high tide at sea, the underwater heat exchange coil tube ( A situation in which the heat capacity of 10) is greatly insufficient may be generated, and in preparation for this, instead of reducing the heat load to the heat exchange coil tube 10 by reducing the operation of the heat exchanger 30 during the refining season, heat storage in the heat storage tank 4 Make sure to use the calories burned.

In this way, sufficient heat can be secured through the heat storage tank 4 even when the flow rate of water is low by heat storage through the heat storage tank 4.

On the other hand, when installed and operated in the sea, low tide and high tide occur, and there is a rectifier between them. In this case, the flow rate is very low and sufficient heat cannot be recovered, and the operation rate of the heat exchanger 30 according to the change in the flow rate A flow rate sensor and a controller may be provided so as to be different.

The flow rate sensor is installed on, for example, the front end header 12 or the outside of the heat exchange coil pipe to sense the speed of a current such as an algae or an ocean current.

In the controller, a database is built to control the operation rate of the heat exchanger 30. This database stores the operation rate (operation rate of the compressor of the heat exchanger 30) along with various flow rates (for example, a flow rate of 1 m / sec. When the compressor operation rate is 20%, etc.).

The controller controls the operation of the compressor by comparing the current flow rate detected by the flow rate sensor with the reference information in the database.

10. Underwater hood.

The discharge section 92 is a form of expansion pipe that increases the area of water passing to the discharge end for rapid discharge. That is, the underwater hood 90 can be installed freely according to the flow of water by configuring the inlet portion 91 and the outlet portion 92 symmetrically.

In addition, a propeller 93 for forming a separate water flow to secure a flow rate of a water flow may be constructed and installed in a water purifier to achieve heat exchange of a certain capacity. The propeller 93 functions to increase the heat exchange efficiency by forming a water flow on the heat exchange coil tube 10 side so that the seawater exchanges its position after heat exchange. Of course, the seawater, which is heated by heat exchange, has a relatively low specific gravity and moves to the upper layer. At this time, the propeller 93 plays a role in more smoothly moving the water.

The propeller 93 can be installed both upstream and downstream of the underwater heat exchange coil tube 10.

In the drawing, the propeller 93 is shown to be operated with the underwater hood 90, but is not limited thereto, and the propeller 93 and the underwater hood 90 can be operated alone or in combination.

The heat exchange chamber 350 is configured with a water tank side heat exchanger 360 that recovers heat from the heat exchanger 30.

The water tank side heat exchanger 360 is composed of a water tank side heat exchange tube 361 through which the heat medium circulates, and a circulation pump 362 for circulating the heat medium.

The water tank-side heat exchange tube 361 is piped over the heat exchanger 30 and the heat exchange chamber 350 of the water tank 300 in a loop form.

Unlike the form of FIG. 21, the conventional method is a method using a separate heating medium circulation.

In addition, it is also possible to operate two or more water tanks 300 together, and the branch pipe 363 is branched to the heat exchange pipe 361 on the water tank side to allow the heat medium to circulate, thereby cultivating heat circulating through the branch pipe 363. It is also possible to use it as a heat source.

The heat exchange method between the heat medium and the cultured water flowing along the branch pipe 363 is, for example, a method of using a heat exchanger 364 for heat exchange between the branch pipe 363 and the cultured water circulation pipe 365.

Fish and shellfish cannot withstand the temperature deviation of the circulating aquaculture water supplied through the heat pump type heat exchanger 30 and maintain the optimal aquaculture water circulation temperature to prevent the occurrence of mortality and prevent the rapid temperature deviation from occurring. A temperature control valve 600 is installed and operated in the circulating aquaculture water and seawater direct water supply pipe, but a controller having a temperature control function can be configured so that it can be supplied by adjusting so that there is no significant difference from the temperature of the aquaculture tank 300 at all times. . Excavating the underground water hole 410, taking into account the characteristics that the groundwater has fourteen seasons constantly maintained at 15-17 degrees Celsius, the pumped underground water is supplied to the culture tank 300 through the temperature adjustment valve 600. (300) In order to contribute to the temperature adjustment.
