Description

  The present invention relates to an air conditioner in a ship cabin and a water temperature adjustment system for a ship's ginger.

For example, for small, medium-sized and larger class vessels used for fishing, sightseeing sightseeing, cruising, other marine leisure activities, fishing and research, etc. A cabin (chamber) equipped with break facilities is provided on board. Since the temperature of the cabin of a ship rises especially in summer or in a warm climate, an air conditioner may be installed. For example, a ship air conditioner proposed in Patent Document 1 is connected to a refrigerant compressor 2, an outdoor heat exchanger 4, a decompression device 5, an indoor heat exchanger 6 and the like to form a refrigerant circuit of a heat pump. For example, in the case of indoor cooling operation, the outdoor heat exchanger functions as a condenser, and the indoor heat exchanger functions as an evaporator to exchange heat between the refrigerant and the air in the ship to cool the ship. At this time, the outdoor heat exchanger of the air conditioner is cooled by seawater taken from outside the ship through a pump, and the seawater heat-exchanged with the refrigerant in the outdoor heat exchanger is discharged out of the ship through the drain pipe. It has become so. In the case of indoor heating operation, the refrigerant circulation direction is switched via a four-way switching valve provided in the refrigerant circuit, and the outdoor heat exchanger functions as an evaporator and the indoor heat exchanger functions as a condenser. Heat up.
JP-A-5-319389

  However, in the marine air conditioner disclosed in Patent Document 1, the outdoor heat exchanger is cooled with seawater taken from outside the ship as described above, and therefore the cooling water intake pipe and the drainage are provided so as to penetrate the hull. It is a complicated structure that requires cooling water equipment with pipes installed, and it is necessary to install members in the engine room below the cabin and in the narrow and dark space inside the hull, so the construction becomes complicated. The work required labor, time, and cost. In particular, in order to install an air conditioner retrofitted to an existing ship, it may be necessary to lift the ship from the sea and apply large processing to the hull, which requires more time and labor for the work. In addition, maintenance including periodic inspections and replacement of parts in the event of failure must be performed in a narrow space inside the engine room or the hull, which is cumbersome and takes a long time, and also increases the maintenance cost for parts replacement, etc. There was a problem. Furthermore, for example, the cooling water intake is provided at a portion below the inundation line of the hull, that is, at the bottom of the hull, but the hull moves up and down due to the resistance of waves and water when the vessel is running. Alternatively, there are cases where the cooling water cannot be sufficiently taken in, for example, swaying back and forth and from side to side and the intake port rising above the water surface. For this reason, the outdoor heat exchanger of the cabin air conditioner is not sufficiently cooled, causing an abnormality in the refrigeration cycle, resulting in a decrease in cooling efficiency, or the air conditioner may be stopped. At the same time, there was a risk of burning of the auxiliary engine and the like.

  In addition, some vessels such as pleasure boats and fishing boats are provided with a ginger to keep the captured seafood alive, but the temperature of the seawater in the ginger tends to rise in summer and temperate sea areas. There was a risk that the seafood in the ginger was weakened or died due to the rise in the temperature of the inner seawater.

A cabin interior air conditioner, an exterior cabin air conditioner that is installed outside the cabin, and is integrated with a heat exchanger, a blower, and a hollow case body integrated with the cabin interior air conditioner and an air conditioning medium; A compressor unit installed outside the cabin and coupled to the cabin air conditioner and the cabin exterior air conditioner, respectively, between the cabin interior air conditioner and the cabin exterior air conditioner, between the compressor unit, the cabin interior air conditioner and the cabin, respectively. A medium pipe that is arranged between the outer air conditioners and couples them to an air conditioning medium; and a portable power supply that supplies driving power to each of the cabin outer air conditioner, the cabin inner air conditioner, and the compressor unit. Therefore, the entire work including transportation and installation of each device and unit, piping, electrical wiring, etc. can be carried out on the deck and in the cabin, so in the narrow and dark space inside the engine room and the hull as before. The construction is extremely simple and can be done in a short time, and the cost is low. It can be installed retrospectively with simple construction regardless of whether it is a new or existing ship. In addition, maintenance can be performed easily and in a short time with only work on board. Furthermore, each cabin interior air conditioner, cabin exterior air conditioner, and other units can be made relatively compact and lightweight as the minimum configuration capable of performing their respective functions, resulting in low cost manufacturing and construction. The operator can easily carry them at the time of installation, and each can be set at a free installation position.In addition, it does not take up space on limited decks or cabins. Good work space can be secured, making it difficult to get in the way. Further, for example, when cooling the cabin, the air-conditioning medium is smoothly operated by stably performing heat exchange outside the cabin via outside air regardless of whether the boat is stopped or traveling. The temperature can be adjusted reliably.

  Each of the cabin interior air conditioning device and the cabin exterior air conditioning device has a hollow case body having at least a peripheral wall and a ceiling wall, and allows a large number of air to enter and exit the case body over one side wall of the peripheral wall. Since the heat exchanger provided with air flow holes is stretched, the heat exchange area between the air-conditioning medium and air is improved by maintaining a large heat exchange area while maintaining a simple and compact structure. Air conditioning efficiency in the cabin can be improved.

  The heat exchanger is composed of a heat exchange wall provided with a large number of fins and a coil communicating with the medium pipe, and provided with the large number of air flow holes. A configuration that is set so as to be orthogonal to the wall body, and that the blade body is opposed to the heat exchange wall body so that air is passed from the outside of the heat exchange wall body and sucked. As a result, it is possible to generate a large wind pressure in the heat exchanger while allowing a large amount of air to be exchanged in a large amount and at a high speed while taking a large heat exchange area. The exchange efficiency is high, and the air conditioning efficiency in the cabin can be further improved. Furthermore, the structure is simple and can be manufactured at low cost.

It can be installed freely in an unobstructed position. Further, for example, the flexible tube discharge port can be freely set in a direction in which a person is present in the cabin, and in an unmanned direction or in a direction in which there is no equipment outside the cabin.

  Further, the water temperature adjusting system for a ship's ginger according to the present invention is a water temperature adjusting system for a ship's ginger using any of the above-described air conditioners in the ship's cabin, and a part of the medium pipe is arranged in the liquid. In addition, mediating liquid means for arranging a part of the detour circulation pipe that diverts and circulates the inhabiting water in the ginger for keeping fish alive, and medium piping arranged in the liquid in the mediating liquid means In order to cool and adjust the temperature of the inhabiting water in the ginger, for example, in summer or in warm waters, effectively using the temperature change of the air-conditioning medium in the air conditioner in the cabin. It is possible to prevent the decline and death of captured seafood due to rising seawater in the ginger. At that time, since the detour circulation pipe is arranged in the intermediate liquid means, the condensed water generated around the intermediate pipe is not mixed with the inhabiting water in the ginger, and the seawater salinity decreases due to the decrease in the salinity of seawater. The quality can be maintained in a state where the seafood is satisfactorily utilized without causing weakness or death.

  In addition, by adopting a configuration including a heat exchanger disposed in the liquid in the intermediate liquid means and attached to a part of the bypass circulation pipe, for example, a heat exchanger in which fins for expanding the contact area are attached to the pipe Etc. can be installed to promote the heat exchange efficiency between the liquid of the intermediate liquid means and the seawater of the ginger in the bypass circulation pipe, and the temperature of the inhabiting water in the ginger can be adjusted efficiently.

  Further, since the mediating liquid means is composed of a water tank that stores liquid therein, the mediating liquid means can have a simple and simple structure and can be manufactured at low cost.

  DESCRIPTION OF EMBODIMENTS Hereinafter, a cabin air conditioner and a ship ginger water temperature adjustment system according to the present invention will be described with reference to the accompanying drawings. 1 to 5 show a first embodiment of a cabin air conditioner according to the present invention. In the present embodiment, the cabin air conditioner is, for example, a small-sized or medium-sized pleasure boat, a sightseeing boat, a recreational fishing boat, a survey used for fishing, sightseeing sightseeing, marine leisure and fishing, surveys, etc. as shown in FIG. The air conditioner is installed in a ship S in which a ship interior R space surrounded by a cabin body Q is provided on a ship body such as a ship and adjusts the temperature in the ship interior. As shown in FIGS. 1, 2, and 3, the cabin air conditioner 10 includes a cabin interior air conditioner 12, a cabin exterior air conditioner 14, a compressor unit 16 installed outside the cabin, a medium pipe 18, 19 and 20 and a portable power supply device 22.

  As shown in FIGS. 1, 2, and 3, the cabin interior air conditioner 12 is installed at an arbitrary position in the cabin R, for example, on a floor or a wall surface, and includes a heat exchanger 24, a blower 26, These are provided integrally with the hollow case body 28. Since the inner air conditioner has a simple member configuration as described above, for example, the entire inner air conditioner has a weight of about several kilograms and is relatively light in weight, and is provided so that the installer can easily carry it. The hollow case body 28 is formed in an internal hollow rectangular box shape having four peripheral walls, a top wall and a bottom wall, and bolts or the like are used on the floor or wall of the ship cabin so as not to move due to the shaking of the ship. Fixed. In the hollow case body 28, for example, a metal plate is stretched over three peripheral walls, a top wall, and a bottom wall on the left and right sides and the back side except the front side, on a metal frame assembled in a rectangular parallelepiped shape. A heat exchanger 24 is stretched over the entire side wall corresponding to the front side of the peripheral wall of the hollow case body 28. The heat exchanger 24 is provided with a number of air flow holes that allow air to enter and exit the hollow case body 28, and heat-exchanges the air-conditioning medium and the air that enters and exits the case body, thereby conditioned air in the cabin. Form. In this embodiment, the heat exchanger 24 of the cabin interior air conditioner 12, the heat exchanger of the cabin exterior air conditioner 14, which will be described later, and the compressor unit 16 constitute a refrigerant circuit of an air-cooled heat pump. For example, an air-conditioning medium (refrigerant) that is easily vaporized such as ammonia is connected to realize a refrigeration cycle inside. The heat exchanger 24 of the cabin interior air conditioner 12 operates as an evaporator when the cabin is cooled, and as a condenser when the cabin is heated. As shown in FIGS. 4 and 5, in the present embodiment, the heat exchanger 24 is, for example, a frame body 31 on the outside of one copper tube tube 32 that is formed in a meandering shape and passes an air conditioning medium. A coil is formed by arranging a large number of fins 30 made of a thin metal plate of aluminum or the like supported in parallel with each other in parallel with a predetermined interval so as to provide a large number of air flow holes. That is, the heat exchanger 24 is composed of a heat exchange wall body including a large number of fins and coils provided in a wall shape so as to form a front peripheral wall of the hollow case body 28, and a separation gap between the large number of fins. Is an air flow hole. The ends of the coil tube 32 that extend to the outside are connected to the medium pipes 18 and 20. A drain pan 37 for receiving condensed water of water vapor in the air condensed by the fins 30 is disposed on the bottom wall side of the hollow case body 28. The drain pan 37 is composed of a container having a deep bottom to some extent, and the received water is not easily spilled even under the influence of the shaking of the ship or the wind pressure of the blower. The blower 26 is composed of, for example, an axial fan provided with a plurality of blade bodies 36 attached in the radial direction of the rotation shaft 34 of the electric motor 35, and is arranged in the hollow case body 28 via a support bracket. The blower 26 sets the rotary shaft 34 in a direction orthogonal to the heat exchange wall body, and allows air flow from the outside of the heat exchange wall body with the blade body 36 facing the heat exchange wall body. It is provided so that air can be sucked through the flow hole. Thereby, while forming the heat exchanger 24 in a large area, a relatively strong wind pressure is generated in the heat exchanger 24, and a large amount of air to be heat exchanged can be passed at a high speed. Heat exchange efficiency can be obtained. Moreover, the hollow case body 28 may have a filter stretched around the peripheral wall position of the heat exchanger through which air enters and exits.

  On the top wall side of the hollow case body 28, an air discharge hole 38 sucked from the outside of the heat exchange wall body through the blower 26 is provided. While sucking air from outside to the inside along the direction of the rotation axis 34 of the blower 26 from the front peripheral wall side of the hollow case body 28 (W1 in FIG. 1), the air is released from the top wall side toward the rotation tangential direction of the blower 26. Air is released from the outlet 38 to the outside of the case body (W2 in FIG. 1). Since the discharge port 38 is provided on the top wall side, the discharge port does not interfere with the wall of the cabin or the arranged furniture, machinery, etc., for example, at the side of the cabin wall or on the side of the cabin outer wall on the deck D It can be installed freely in a position that will not interfere with the passengers. The discharge hole 38 is connected to a flexible tube 40 that can freely change the discharge angle of air. For example, the flexible tube can be bent freely to change the angle of the discharge port, and the angle can be maintained, and the discharge port of the flexible tube can be set freely in the direction of the person in the cabin. Can do.

  The cabin outer air conditioner 14 is installed on an arbitrary position outside the cabin T on the boat, for example, on the deck D, and only the heat exchanger 24 and the blower 26 are mounted on the hollow case body 28 and integrated. Is provided. In this embodiment, the cabin outside air conditioner 14 is provided with substantially the same member configuration as the cabin interior air conditioner 12, and the same members are denoted by the same reference numerals, and detailed description thereof is omitted. Since the cabin exterior air conditioner 14 and the cabin interior air conditioner 12 have substantially the same member configuration, for example, when producing the cabin interior air conditioner and the cabin exterior air conditioner in a factory, etc., it is necessary to produce them in separate and independent processes. It is only necessary to arrange the manufactured two air conditioner units on the inside and outside of the cabin at the construction site on the ship. The cabin outside air conditioner 14 has a hollow case body 28 fixed to a deck floor or an outer wall of a cabin with a bolt or the like so as not to move due to the shaking of the ship. The cabin outside air conditioner 14 and the cabin interior air conditioner 12 are joined so that the ends of the tubes 32 of the respective coils are joined to each other via the medium pipe 18 so that the air conditioning medium can flow inside. The heat exchanger 24 of the cabin outer air conditioner 14 is a means for exchanging heat between the air conditioning medium and the outside air to enter and exit the hollow case body 28 outside the cabin, and the heat of the indoor air conditioner 12 in the refrigerant circuit of the configured heat pump. Contrary to the exchanger, it operates as a condenser during indoor cooling and as an evaporator during indoor heating. In the present embodiment, the cabin outside air conditioner 14 is an air-cooled type that cools using outside air when cooling the cabin, for example, so that it can be placed at any position outside the cabin and with other devices, etc. It is only necessary to connect the medium piping in the ship's space, and it is possible to connect the pipe vertically so as to draw water for cooling water, drain water, etc., or make a hole on the bottom side of the ship, or inside the engine room or hull. There is no need for large-scale construction work such as installation of a dedicated cooling facility in a narrow and dark space, and the construction is extremely simple and can be retrofitted to an existing ship by simple construction. Further, regardless of whether the ship is stopped or traveling, the air conditioner can be stably operated by performing heat exchange (cooling) on the outside of the cabin, and the temperature inside the cabin can be adjusted satisfactorily.

  For example, as shown in FIG. 6, the heat exchanger 24 of the cabin interior air conditioner 12 may have a configuration in which, for example, a heating wire heater 52 configured by arranging a heating wire in a hollow glass tube is attached. When the heating wire is energized by electrical resistance, the temperature rises relatively early, so when heating the cabin, the heating wire warms the air early to form conditioned air and raises the indoor temperature. Can improve heating efficiency.

  The compressor unit 16 is installed at an arbitrary position outside the cabin T on the ship, for example, on the deck D, as shown in FIGS. 1, 2, and 3, and the cabin interior air conditioner 12 and the cabin exterior air conditioner 14. Are connected to the respective heat exchangers 24 via the medium pipes 19 and 20 so as to allow the air-conditioning medium to flow inside. In the present embodiment, the compressor main body 42 compresses the air medium evaporated on the heat exchanger side serving as an evaporator and pumps it to the heat exchanger side serving as a condenser in the refrigerant circuit of the heat pump to be configured. 42 and a control unit 44. In addition, you may provide the accumulator which is not illustrated, the liquid reservoir of an air-conditioning medium, etc. The compressor unit 16 includes, for example, a base frame or the like with a metal frame (not shown), and a bolt or the like on the deck floor or the outer wall of the cabin while the compressor main body 36 is supported on the base frame. It is fixed by and cannot be moved by the shaking of the ship. The compressor unit 16 is provided with a control unit 44 for the compressor main body 42, the cabin interior air conditioner 12, and the cabin exterior air conditioner 14, which are electrically connected to each other. Basically, the wind force of the blower 26 of the cabin interior air conditioner 12 and the cabin exterior air conditioner 14 may be constantly rotated. For example, the control unit 44 may control the blower 26 according to the set temperature. You may enable it to change an air volume.

  In the present embodiment, the medium pipes 18, 19, and 20 are provided between the cabin interior air conditioner 12 and the cabin exterior air conditioner 14, between the compressor unit 16 and the cabin interior air conditioner 12, and between the compressor unit 16 and the cabin exterior air conditioner 14. These are arranged in the three systems, respectively, and are coupled to each other so as to allow the air-conditioning medium to flow inside to constitute a refrigerant circuit of the heat pump. The medium pipes 18, 19, and 20 are made of, for example, thin copper pipes and the like, and a heat insulating material (not shown) is externally provided as necessary, and the space between the compressor unit 16 and the cabin outer air conditioner 14 is provided. As necessary, the walls of the cabin are provided between the cabin interior air conditioner 12 and the cabin exterior air conditioner 14 and between the compressor unit 16 and the cabin exterior air conditioner 14 while being piped on the deck D outside the cabin or along the outer wall of the cabin body. Etc. are penetrated and piped outside and inside the ship cabin, and each end is coupled to each device. Each of the ends of the medium pipes 18, 19, 20 and the ends of the tube 32 of the coil of the cabin air conditioner 12, the cabin outside air conditioner 14, or the inlet / outlet ends of the air conditioning medium to and from the compressor body of the compressor unit 16. The connection is connected and fixed by, for example, joining by fitting different diameter pipes, screwed screw connection, other one-touch type joints, couplers, or the like. The medium pipes 18, 19 and 20 are freely arranged on the deck or outside the cabin according to the three devices, the cabin interior air conditioning device, the cabin exterior air conditioning device, and the compressor unit, which are relatively simple work. Can be installed. The pressure of the high-pressure air-conditioning medium that has passed through the heat exchanger compressed by the compressor main body 44 and passed through the heat exchanger is placed at an intermediate position of the medium pipe 18 that connects the air-conditioning apparatus 12 inside the cabin and the air-conditioner outside the cabin 14. An expansion valve 48 is interposed to lower the temperature of the air-conditioning medium. The medium pipes 19 and 20 are provided with an electromagnetic four-way switching valve 46 for switching the flow direction of the air conditioning medium. The four-way switching valve 46 is controlled via the control unit 44, and reverses the evaporator and condenser of each heat exchanger 24 of the cabin interior air conditioner 12 and the cabin exterior air conditioner 14, thereby cooling and heating the cabin. Switch. The four-way switching valve 46 is electrically connected to the control unit 40 and switches the flow direction of the air-conditioning medium by an electric signal.

  The portable power supply device 22 is installed on an arbitrary position outside the cabin T on the ship, for example, on the deck, and supplies driving power to the cabin air conditioner 12, the cabin outside air conditioner 14, and the compressor unit 16. . The portable power unit 22 includes, for example, a generator that generates electric power from an air-cooled internal combustion engine using a liquid fuel such as gasoline and outputs a DC or AC voltage, and is relatively small and sized to be carried on a deck or the like. . For example, the portable power supply device 22 is fixed on the deck or the outer wall of the cabin body with a bolt or the like so as not to move due to the shaking of the ship. For example, the portable power unit 22 generates power at a voltage of 100 V and distributes and supplies power to the compressor unit 16 and the air conditioners 12 and 14 inside and outside the cabin, and penetrates the outside of the cabin body and the cabin body wall. The electric wiring 23 is supplied to the cabin interior side to supply power. The power supply system to the cabin interior air conditioner 12 and the cabin exterior air conditioner 14 is connected via a transformer 50 that converts the generated 100V voltage to a low voltage of 12V, and a low voltage of 12V is applied to each blower. It can be driven for a long time with relatively low output. For example, a switch (not shown) capable of controlling on / off operation of the air conditioner is interposed in the electric wiring 23 wired in the cabin.

  When installing the air conditioner 10 in the cabin according to the present embodiment on the ship, for example, as shown in FIGS. 2 and 3, the cabin air conditioner 12 is installed on the floor of the wall on the cabin side R, and the cabin on the ship is installed. The cabin outside air conditioner 14, the compressor unit 16, and the portable power supply device 22 are carried in and installed at arbitrary positions on the outer T deck. Since each device and unit is relatively small and lightweight, it can be easily carried by the operator, and it can be easily fixed to the hull compared to fixing heavy items, such as by bolting. It can be done. In addition, the installation position of each device and unit can be set freely without taking up space on a narrow deck, and it is difficult to interfere with work on the deck. If necessary, a hole or the like is made in the cabin wall, between the cabin interior air conditioner 12 and the cabin exterior air conditioner 14, between the compressor unit 16 and the cabin interior air conditioner 12, and between the compressor unit 16 and the cabin exterior air conditioner 14. The medium pipes 18, 19, and 20 are respectively arranged in the three systems, and the respective ends are connected. Furthermore, the electrical wiring from the portable power supply device is connected to the cabin interior air conditioner 12, the cabin exterior air conditioning device 14, and the compressor unit, respectively. The entire construction work including transportation and installation of each device, piping, electrical wiring, etc. can be done on the deck and in the cabin, so there is no need for work in a narrow and dark space inside the engine room or the hull as before, easy, In addition to being able to work in a short time, the equipment is simple and the manufacturing cost is low. In addition, maintenance is easy. For example, when cooling the cabin in the summer or warm waters, the heat exchanger of the cabin air conditioner is operated as an evaporator and the heat exchanger outside the cabin is used as a condenser to operate the refrigerant circuit of the heat pump. The air conditioning medium evaporates in the heat exchanger (evaporator) and the temperature of the cabin air is lowered by the heat of vaporization. The air-conditioning medium heat-exchanged by the heat exchanger is compressed by the compressor main body and becomes a high temperature, and is heat-exchanged with the outside air outside the cabin by the heat exchanger (condenser) of the cabin outside air-conditioner and condensed. Then, the temperature of the air-conditioning medium is lowered by passing through the expansion valve that lowers the pressure, and the air-conditioning medium is again circulated to the heat exchanger (evaporator) of the cabin-side air conditioner. On the other hand, for example, when heating the cabin in winter or cold sea areas, switch the four-way switching valve, operate the heat exchanger of the cabin air conditioner as a condenser, operate the heat exchanger outside the cabin as an evaporator, The air-conditioning medium is cycled in the reverse direction. In the heat exchanger of the cabin air conditioner, the temperature of the room air is raised by exchanging heat between the high-temperature air-conditioning medium from the compressor and the room air. In this way, the temperature of the cabin space can be adjusted satisfactorily.

  Next, with reference to FIG. 7, an embodiment of the water temperature adjustment system for a ship's ginger according to the present invention will be described. The water temperature adjustment system for a ship's ginger according to the present embodiment is applied to a ship provided with a ginger 54 (see FIG. 3) for placing a cabin and captured seafood on a pleasure boat, fishing boat, survey ship, etc. It is a water temperature adjustment system using the air conditioner in the ship cabin of the embodiment.

When the seafood is moved from the ginger to another place when the port is visited, seawater is pumped through a drainage pump (not shown) with the stopper closed. FIG. 7: has shown schematic structure figure of the water temperature adjustment system of the ginger of a ship, attaches | subjects the same code | symbol to the same member as the said embodiment, and abbreviate | omits detailed description. As shown in FIG. 7, the water temperature adjustment system for a ship's ginger is configured such that the cabin air conditioner 12, the cabin outside air conditioner 14, and the compressor unit 16 of the above air conditioner are connected by medium pipes 18, 19, and 20. In the refrigerant circuit of the heat pump configured by coupling the air conditioning medium, the temperature of the ginger is adjusted using the air conditioning medium whose temperature changes.

  In the present embodiment, the water temperature adjustment system for the ginger of the ship arranges, for example, a part of the medium piping 19 connected to the compressor unit 16 from the heat exchanger 24 of the cabin air conditioning device 12 in the liquid 59. An intermediate liquid means for arranging a part of the detour circulation pipe 56 for detouring and circulating the inhabited water 55 in the ginger 54 for keeping the fish alive, and the liquid in the intermediate liquid means. And a heat exchanger attached to the medium pipe 19. The intermediary liquid means includes, for example, a water tank 58 that stores intermediary liquid 59 such as water and seawater, and a part of the medium pipe 20 and a part of the bypass circulation pipe 56 are made inside to store the stored intermediary liquid. Thus, heat exchange is performed between the air-conditioning medium passing through the medium pipe 19 and the inhabiting water in the ginger passing through the bypass circulation pipe 56. A portion of the medium pipe 19 disposed in the liquid 59 in the water tank 58 includes, for example, a large number of fins or the like attached to the outside of the pipe to form a heat exchanger 60, which is connected to the mediator liquid in the water tank. The heat exchange efficiency is improved by increasing the contact area. The detour circulation pipe 56 circulates the inhabited water in the ginger provided in the ship by diverting it into the aquarium, and a pump 64 for forcibly detouring the water in the ginger is interposed in the middle position. ing. A part of the detour circulation pipe 56 disposed in the intermediate liquid in the water tank 58 is provided with a heat exchanger 62 with a large number of fins attached to the outside of the circulation pipe, for example. The contact area with the liquid is increased to improve the heat exchange efficiency. For example, a configuration in which a part of the medium pipe is directly arranged in the seawater of the ginger is conceivable, but when the ginger seawater is cooled through the low-temperature air-conditioning medium in the medium pipe, dew condensation around the cold medium pipe , And the condensed water is mixed in ginger seawater, and the salinity of seawater may be reduced, and fish and shellfish may be weakened and killed. By exchanging heat through the media of the aquarium as in the present embodiment, the quality of the seafood can be maintained well without deteriorating and dying of the seafood. The pump 64 is electrically connected to the portable power supply device via a power supply line (not shown) and electrically connected to the pump control unit 66 and controlled. The pump control unit 66 always receives a temperature signal from a temperature sensor 68 that measures the temperature of the water in the ginger, the temperature set in advance so that the captured seafood can live well, and the temperature data from the temperature sensor 68. And the pump 64 is automatically driven and stopped. Thereby, the water temperature of the ginger can be prevented from being excessively lowered, and the water temperature in the ginger can be reliably adjusted at the set temperature, so that the seafood in the ginger can survive for a relatively long period of time. The pump control unit 66 may be incorporated in the control unit 44 provided in the compressor unit 16.

  Next, the operation of the water temperature adjusting system for ginger according to the present embodiment will be described. This embodiment demonstrates the case where the water temperature of a ginger is cooled, for example, cooling a ship's cabin in summer or a warm sea area. When the cabin is cooled, the refrigerant circuit of the heat pump is operated using the heat exchanger 24 of the cabin air conditioning device 12 as an evaporator and the heat exchanger 24 of the cabin outside air conditioning device 14 as a condenser as in the above embodiment. The air conditioning medium is circulated. At this time, since the low-temperature air-conditioning medium before being compressed passes through the medium pipe 19 connected to the compressor unit 16 from the heat exchanger of the cabin-side air conditioner 12, heat exchange with the intermediate liquid in the water tank is performed. Then, the water in the water tank is cooled. On the other hand, when the water temperature of the ginger rises and the temperature data from the temperature sensor 68 that detects the water temperature in the ginger is higher than the temperature set by the pump control unit 66, the pump 64 interposed in the bypass circulation pipe 56. Is operated by the pump controller 66, and the water in the ginger is caused to flow through the bypass circulation pipe 56. In the portion of the detour circulation pipe 56 disposed in the intermediate liquid in the water tank 58, the intermediate liquid and the water in the ginger are heat-exchanged to cool the water in the ginger. When the temperature falls below the set temperature, the pump control unit 66 stops the pump 64, stops the circulation flow of the bypass circulation pipe, and stops the cooling of the water in the ginger. In this way, the temperature set by the pump control unit 66 and the water temperature in the ginger are compared, and the pump 64 is driven and stopped to adjust the water temperature in the ginger to a constant temperature. Thereby, the air conditioning medium of the air conditioner installed in the ship can be effectively used, and the temperature of the ginger inhabiting water can be adjusted well with energy saving. Conversely, the temperature of the ginger's inhabiting water can also be raised during indoor heating or by changing the medium piping arranged in the liquid in the aquarium. In addition, for example, a switching valve that switches between the path in which the pipe is placed in the liquid in the aquarium and the path in which the heat exchanger and the compressor are directly connected without being placed in the liquid in the water tank is installed in the middle of the path of the medium pipe Then, the route may be switched as necessary. Further, the medium piping to be arranged in the liquid in the aquarium may be of any system. For example, considering the air conditioning operation state in the cabin and the water temperature control in the ginger, the cabin interior air conditioner and the cabin exterior air conditioner It is good also as arrange | positioning a part of medium piping 18 between the medium piping 18 between a compressor unit, and a cabin exterior air conditioner in the liquid of a water tank.
