  However, in Patent Document 1, since the outdoor heat exchanger 103 and the compressor 104 are configured as a single unit, they are larger than those configured individually, so they are mounted in a narrow place such as a ship. In some cases, it may be an obstacle to other machines, etc., and it may not be subdivided during transportation, which may be annoying and bulky.

  In Patent Document 2, as shown in FIG. 15, the refrigerant circuit is configured so that the refrigerant discharged from the compressor 111 flows in the order of the four-way valve 112, the refrigerant-to-water heat exchanger, and the air-cooling outdoor heat exchanger 113 during the cooling operation. A refrigerant-to-water heat exchanger 113 is disposed in the heat exchanger 113 and heat is exchanged with the refrigerant in the refrigerant-to-water heat exchanger 113, so that warm water is taken out during the cooling operation during cooling operation and cold water is taken out during the heating operation. However, cold water cannot be taken during cooling operation, and hot water cannot be taken during heating operation. Therefore, when the air conditioner of the present embodiment is installed on a ship, cold water cannot be taken during the cooling operation in the summer, so that it is not possible to keep the fish in the cold water until the fish caught is returned to the shore. In addition, there is a problem that when you want to take a bath in the winter season, you can not take hot water and you can only get cold water, so you can not wash your body comfortably in the bath until you return to the shore.

  In order to achieve the above object, claims 1 to 6 of the present invention provide an air conditioner in which an outdoor heat exchanger unit, an indoor heat exchanger unit, and a compressor unit are individually arranged, respectively. Claims 1 to 5 relate to the configuration, and since the outdoor heat exchanger unit, the outdoor heat exchanger unit, and the compression unit are independently arranged, the air conditioners can be appropriately dispersed and arranged. it can. The sixth aspect relates to temperature control in the air conditioning room.

  According to a seventh aspect of the present invention, the outdoor heat exchanger and the indoor heat exchanger of the air conditioner are connected to the heat exchanger, the heat exchanger is arranged in the liquid tank, and the temperature of the liquid stored in the liquid tank is adjusted. A hot water and cold water supply system is provided.

  According to the eighth aspect of the present invention, even if the outdoor and indoor heat exchangers are switched for cooling and heating by the operation of the switching valve that is switched in conjunction with switching between the cooling operation and the heating operation, the outdoor and indoor heat exchange is performed. Each liquid tank following the vessel provides a hot water and cold water supply system in which the cold water remains for cold water and the hot water remains for hot water in any state.

  Claim 9 provides a hot water and cold water supply system that can adjust the temperature of the liquid in the liquid tank to a temperature suitable for the liquid in any operating state by switching the switching valve simultaneously with the switching of the cooling operation or the heating operation. Is.

  A tenth aspect of the present invention provides a hot water and cold water supply system comprising a three-way valve or a combination of two-way valves as a switching valve that switches in conjunction with switching of the cooling operation or the heating operation.

  As described above, in the air conditioner of the present invention, the outdoor heat exchanger unit, the indoor heat exchanger unit, and the compressor unit are independently arranged. Each unit can be distributed and arranged as compared with the case where two units are integrated. In addition, since the compressor unit can be arranged outside the room, there is an effect that the room can be quiet.

  Further, cold water or hot water can be produced by using the cool air by the cooling of the indoor heat exchanger unit and the outdoor heat exchanger unit or the warm air by heating.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS.

FIG. 1 is a conceptual diagram showing a first embodiment of the present invention.

  5 is a 1st heat exchanger, 6 is a 1st air blower, and comprises the outdoor air conditioning unit 1 with these. 7 is a second heat exchanger, 8 is a second blower, 9 is an expansion valve, and 10 is a throttle, and these constitute an indoor air conditioning unit.

  11 is an electric wire that feeds power from the power supply unit 4 to the first blower 6, the second blower 8, and the compressor indicated by 12 arranged in the compression unit.

  Reference numeral 13 denotes an electromagnetically operated four-way valve disposed in the compression unit 3, reference numeral 14 denotes a medium pipe through which the refrigerant flows, reference numeral 15 denotes a control device, reference numeral 16 denotes a temperature sensor, and reference numeral 17 denotes an air conditioning switching switch.

Next, the operation of FIG. 1 will be described.
When the air conditioning switching switch 17 for switching between the air conditioning mode and the air heating mode is operated, the four-way valve 13 is in a state of a solid line or a broken line in the figure. When the cooling mode is set, the operation of the four-way valve 13 is electromagnetically switched as indicated by a solid line. From the port A of the compressor 12, the refrigerant changes from a gas to a high-temperature, high-pressure semi-liquid and flows as shown by a solid line. When passing through the expansion valve 9, the high-temperature and high-pressure semi-liquid changes to a semi-liquid that has changed to a slightly low pressure. When the high-temperature semi-liquid that has been changed to a slightly low pressure passes through the heat exchanger 5 of the indoor air conditioning unit 1, warm air comes out by the blower 6. The high-temperature semi-liquid that has been changed to a slightly low pressure becomes a liquid whose temperature has been lowered by the blower, and becomes a gas whose temperature has decreased when passing through a throttle unit 10 provided in the indoor air conditioning unit 2, for example, a capillary 10 such as a capillary tube. After passing through the heat exchanger 7, cold air is discharged into the room by the blower 8. The low-temperature gaseous refrigerant returns to the port B of the compressor 12 through the four-way valve 13, and the refrigerant is compressed again to change into a high-temperature and high-pressure semi-liquid, and the above operation is repeated.

  When the temperature of the room becomes lower than the temperature preset by the control device 15 by the output of the temperature sensor 16 arranged in the indoor air conditioning unit 2, the signal is input to the compressor 12 port C to stop the driving of the compressor, In addition, when the indoor temperature becomes higher than a preset temperature, the control of the compressor 12 is resumed.

  Next, when a changeover switch (not shown) is switched to the heating mode, the four-way valve 13 is switched as shown by a broken line, and a high-temperature, high-pressure semi-liquid refrigerant flows from the port A in the direction of the broken line arrow. 2 enters heat exchanger 7. Warm air enters the room by the blower 8 and the room is heated. The high-temperature, high-pressure semi-liquid refrigerant changes to a low-temperature, high-pressure liquid refrigerant when passing through the second heat exchanger. When the low-temperature and high-pressure liquid refrigerant passes through the throttle unit 10, the refrigerant changes into a low-temperature and low-pressure gas refrigerant, and when passing through the first heat exchanger 5 of the outdoor air conditioning unit 1, the cold air is discharged. The low-temperature and low-pressure gaseous refrigerant returns to the port B through the expansion valve 9.

  FIG. 2 shows the first heat exchanger 5 of the outdoor air conditioning unit 1. A plurality of pipes X arranged in the first heat exchanger 5 are connected by U-shaped pipes indicated by Y, and the pipes are formed in a single pipe from the inlet to the outlet where the refrigerant is put in the first heat exchanger 5. Is formed. One pipe through which the refrigerant passes passes through a plurality of pipes with respect to the air outlet, covers the opening also in terms of area, and sends cool air or warm air from the blower to increase the cooling effect or heating effect. The 2nd heat exchanger 7 of the indoor air-conditioning unit 2 is also the same as FIG.

  FIG. 3 shows a case where the heat generated from the air conditioner shown in FIG. 1 is used for hot water, and the cooling air is put in a water tank and used for fish sacrifice. The medium pipe from the first heat exchanger 5 to the third heat exchanger 19 immersed in the first liquid 20 in the first liquid tank 18 is divided into 14A, 14V, and 14B by the medium pipe 14. The medium piping from the second heat exchanger 7 to the fourth heat exchanger 22 immersed in the second liquid 22 of the second liquid tank 21 is divided into 14C, 14W, and 14D. Further, medium pipes 14X and 14Y that cross the left and right medium pipes are prepared. When the room is in the cooling mode, the medium pipes 14A, 14V, and 14B from the heat exchanger 5 to the third heat exchanger 18 are connected in the same manner as in FIG. 1, and the heat exchanger 18 to the first heat exchanger 5 are connected. Allow the refrigerant to flow. Further, the medium pipes 14 </ b> C, 14 </ b> W, 14 </ b> D from the second heat exchanger 7 to the fourth heat exchanger 22 are connected so that the refrigerant flows from the second heat exchanger 7 to the fourth heat exchanger 22. To. Further, a medium pipe 14E is provided between the third heat exchanger 19 and the expansion valve 9, a medium pipe 14F is provided between the expansion valve 9 and the four-way valve 13, and a medium pipe is provided between the four-way valve 13 and the port A of the compressor 12. 14G is connected. A medium pipe 14H is connected between the port B of the compressor 12 and the heat exchanger 22. Further, a medium pipe 14K between the first heat exchanger 5 and the throttle unit 10 in the indoor air conditioning unit 2, for example, a capillary is connected, and a medium pipe 14L is connected between the throttle unit 10 and the heat exchanger 7.

  When the room is in the cooling mode, a high-temperature, semi-liquid high-pressure refrigerant flows from the port A of the compressor 12 through the medium pipe 14G, the four-way valve 13, and the medium pipe 14F, and the pressure at the high temperature is slightly increased through the expansion valve 9. It is lowered and passes through the heat exchanger 18 through the medium pipe 14E. The first liquid 20 contained in the first liquid tank 18 is warmed by the third heat exchanger 18. The high-temperature and slightly high-pressure refrigerant is guided to the heat exchanger 5 through the medium pipes 14B, 14V, and 14A. Warm air is released by the operation of the blower 6. The refrigerant whose temperature has been slightly lowered by the blower 6 and has been liquefied passes through the medium pipe 14K, passes through the throttle unit 10 and the medium pipe 14L, and becomes a gas at a low temperature. The blower 8 cools the room and cools the room. The refrigerant is guided to the fourth heat exchanger 23 through the medium pipes 14C, 14W, and 14D, and the second liquid 22 contained in the second liquid tank 22 is cooled. Then, the refrigerant is returned to the port B of the compressor 12 through the medium pipe 14J, the four-way valve 13, and the medium pipe 14H.

Next, when the room is switched from the cooling mode to the heating mode by operating the cooling / heating switching switch 17, the end of each medium pipe is sealed so that the refrigerant does not spill outside, and the medium pipe 14A and the medium pipe 14B are arranged. The medium pipe 14V is removed, and instead, the medium pipe 14X is connected between the medium pipe 14A and the medium pipe 14D.

Further, as shown in FIG. 3, the four-way valve 13 is brought into the same state as that in the cooling mode even in the heating mode.

The operation when the room is set to the heating mode by operating the air conditioning switch 17 is as follows.
High-temperature, semi-liquid refrigerant from the compressor 12 passes through the third heat exchanger 19 through the expansion valve 9 in the same manner as in the cooling mode. Therefore, the first liquid 19 in the first liquid tank 18 is warmed in the same manner as in the cooling mode. The refrigerant passes through the medium pipe 14B, passes through the medium pipe 14Y, passes through the medium pipe 14C, and is guided to the heat exchanger 7. The high-temperature refrigerant is warmed by the blower 8 from the heat exchanger into the room and heats the room. The high-temperature refrigerant is cooled by the blower 8, and the pressure is lowered by passing through the throttle unit 10, for example, the capillary, and is guided to the first heat exchanger 5. Cold air is discharged from the first heat exchanger 5 by the blower 6. The cooled refrigerant discharged from the blower 6 is guided to the fourth heat exchanger 23 through the medium pipe 14 </ b> D through the medium pipe 14 </ b> X, and the second liquid 22 put in the second liquid tank 21. Is cooled. The refrigerant is returned to the compressor 12 through the medium pipes 14J and 14H.

When the heating mode is set, the three-way valves 40 and 50 are switched to the broken line side. That is, the refrigerant flows from the medium pipe 14Y to the heat exchanger 7 through the medium pipe 14A, and flows from the heat exchanger 5 to the medium pipe 14Y through the medium pipe 14C. The three-way valve is an electromagnetic type, and a signal is output from the control device 15B by the operation of an air conditioning switching switch 17 on an operation panel (not shown) and is switched electromagnetically. With respect to the operation, in FIG. 3, the place where the medium pipe is manually replaced is switched electromagnetically.
