  The first space 11 is divided into, for example, three spaces along the vertical direction, as shown in FIG. Each of the three spaces has a belt conveyor 11a. For example, a wire mesh 11f is disposed on the belt conveyor 11a, and the young chick C1 is reared thereon. The manure excreted by the juvenile chick C1 falls to the belt conveyor 11a via the wire mesh 11f and is discharged to the outside by the belt conveyor 11a. Moreover, the dehumidifier 51 mentioned later is attached to the wall 11b on the opposite side to the side in which the 2nd space 12 of the 1st space 11 is provided.

Moreover, the gas heat exchanger 50 is attached to the wall 12b on the opposite side to the side in which the 1st space 11 of the 2nd space 12 is provided. The heating path 30 is not disposed below the floor of the second space 12.

  The heat pump 20 is configured to be able to simultaneously take cold heat and heat. The heat pump 20 is also configured to be able to take out only the heat. Since the heat pump 20 is an electric type, it does not use fire and there is no need to worry about fire. Hereinafter, the configuration of the heat pump 20 will be described in detail with reference to FIG.

  As shown in FIG. 2, the heat pump 20 includes a refrigerant flow path 21 in which the refrigerant circulates, a compressor 22 that compresses the refrigerant, an expansion valve 23 that expands the refrigerant, and a first medium that circulates in the heating path 30.

Further, the branched second flow path 21b and the third flow path 21c merge with the first flow path 21a at the merging portion 21d.

The compressor 22 is provided in the first flow passage 21a. Although the compressor 22 is not particularly limited, for example, a CO ₂ refrigerator can be used. The compression of the refrigerant as it passes through the compressor 22 raises the temperature of the refrigerant. The temperature of the refrigerant before passing through the compressor 22 is, for example, 5 ° C., and the temperature of the refrigerant after passing through the compressor 22 is, for example, 90 ° C.

  The expansion valve 23 is provided in each of the second flow passage 21 b and the third flow passage 21 c. The expansion valve 23 provided in the second flow passage 21 b is disposed between the switching valve 28 and the cold water heat exchanger 25. The expansion valve 23 provided in the third flow passage 21 c is disposed between the switching valve 28 and the air heat exchanger 26. Only one expansion valve 23 may be disposed between the hot water heat exchanger 24 and the switching valve 28. The expansion valve 23 reduces the temperature of the refrigerant by being expanded when the refrigerant passes through the expansion valve 23.

  The switching valve 28 switches the supply of the refrigerant passing through the first flow passage 21 a to the second flow passage 21 b or the third flow passage 21 c.

  According to the heat pump 20 configured as described above, for example, the first flow passage 21 a is switched by switching the switching valve 28 so that the refrigerant passing through the first flow passage 21 a is supplied to the second flow passage 21 b. And the second flow path 21b are connected. As a result, the hot water heat exchanger 24 heats the first medium circulating in the heating path 30, and the cold water heat exchanger 25 cools the second medium circulating in the cooling path 40. For this reason, the heat pump 20 is in a state where it is possible to simultaneously take out heat and cold.

  On the other hand, the first flow path 21a and the third flow path 21c are connected by switching the switching valve 28 so that the refrigerant passing through the first flow path 21a is supplied to the third flow path 21c. As a result, the hot water heat exchanger 24 heats the first medium circulating in the heating path 30, and the air heat exchanger 26 cools the air taken in from the outside, and the air cooled by the discharge fan 27 Is discharged to the outside. For this reason, the heat pump 20 will be in the state which can take out only heat.

  The connection path 45 is connected to the second heating path 32 or the cooling path 40 at the switching valve V3. The switching valve V3 switches the supply of the first medium flowing through the second heating path 32 or the second medium flowing through the cooling path 40 to the connection path 45.

  As shown in FIG. 1, the connection path 45 has a first connection path 46 in which the gas heat exchanger 50 is disposed, and a second connection path 47 in which a feed pipe heat exchanger 70 described later is disposed. The connection path 45 is branched into the first connection path 46 and the second connection path 47 at the branch portion J2.

The connection path 45 merged at the merging portion J3 is connected to one of the second heating path 32 and the cooling path 40 at the switching valve V4.

  According to the heating path 30, the cooling path 40, and the connection path 45 configured as described above, for example, by switching the switching valves V3 and V4 so that the second heating path 32 and the connection path 45 are connected (see FIG. 4), the first medium heated by the hot water heat exchanger 24 flows through the connection path 45.

  On the other hand, the second medium cooled by the cold water heat exchanger 25 flows through the connection path 45 by switching the switching valves V3 and V4 so that the cooling path 40 and the connection path 45 are connected (see FIG. 3).

  The gas heat exchanger 50 regulates the temperature of the poultry house 10. Specifically, as shown in FIG. 1, the gas heat exchanger 50 adjusts the temperature of the second space 12.

  The gas heat exchanger 50 is disposed in the first connection path 46. A fan F2 is disposed next to the gas heat exchanger 50. By connecting the second heating path 32 and the connecting path 45 in the switching valves V3 and V4, the heat from the first medium can be supplied into the second space 12 by the fan F2, and the inside of the second space 12 is For example, it can warm to 20-35 ° C.

Supply to the dehumidifier 51 (see FIG. 3). The air in the vicinity of the dehumidifier 51 is cooled by the second medium, and the moisture is converted into water droplets to be condensed and eliminated, whereby the dry air is released to perform dehumidification. When the function of the dehumidifier 51 is turned off, the supply of the first medium passing through the second heating path 32 to the dehumidifier 51 is turned off in the switching valve V1, and the cooling in the switching valve V2 is performed. The supply of the second medium passing through the path 40 to the dehumidifier 51 is turned off (see FIG. 4).

  The water supply pipe 60 pumps up the water from the well 85 by the pump P3 and supplies it to the chicken as drinking water. The water supply pipe 60 includes a first water supply pipe 61 provided in the first space 11 and supplying water to the young chick C1, and a second water supply pipe 62 provided in the second space 12 and supplying water to the adult chicken C2. Have.

  The first water supply pipe 61 is attached with a nipple type water supply device 61a for the young chick C1 to drink water. In addition, a nipple-type water dispenser 62a for the adult chicken C2 to drink water is attached to the second water supply pipe 62.

The control unit 90 may automatically switch the switching valve 28, the switching valve V1, the switching valve V2, the switching valve V3, and the switching valve V4, based on the age information and season information of the chicken.

  Next, a method of raising chickens by the chicken breeding system 1 according to the present embodiment will be described. Hereinafter, the method of raising chickens according to the poultry farming system 1 will be described by dividing the seasons into summer and winter.

  First, the case of summer will be described with reference to FIG. In FIG. 3, a thick black line indicates the circulation path of the first medium, and a thick gray line indicates the circulation path of the second medium.

  In summer, due to global warming in recent years, the temperature in the chicken house 10 rises rapidly, and heat death of adult chicken C2 occurs frequently. For this reason, while cooling the 2nd space 12 in which adult chicken C2 is brought up, it is necessary to cool the drinking water of adult chicken C2. On the other hand, it is preferable to make young chick C1 a high temperature environment than adult chicken C2.

  In summer, the switching valve 28 shown in FIG. 2 is switched to connect the first flow passage 21a and the second flow passage 21b, and as shown in FIG. 3, it is possible to simultaneously take out heat and cold from the heat pump 20. The switching valves V3 and V4 are switched to connect the cooling path 40 and the connection path 45.

  As a result, the first heating path 31 can warm the inside of the first space 11 from under the floor of the first space 11. Therefore, a suitable nursery environment can be provided to the young chick C1.

  On the other hand, the gas heat exchanger 50 can supply cold heat from the second medium into the second space 12 by the fan F2, and can cool the inside of the second space 12. In addition, the water supply pipe heat exchanger 70 can cool the drinking water in the second water supply pipe 62 by cold heat from the second medium. Adult chicken C2 has no sweat glands and is covered with feathers, so it can not regulate body temperature by sweating, and heat is less likely to be dissipated, and heat is likely to build up in the body. For this reason, temperature regulation can not catch up if there is a rapid rise in the outside air temperature. Also, adult chicken C2 has the property of drinking more water than other organisms. For this reason, the adult chicken C2 can adjust the body temperature of the adult chicken C2 suitably by the adult chicken C2 drinking the drinking water cooled by the cold heat from a 2nd medium. Therefore, a suitable rearing environment can be provided to adult chicken C2.

  Thus, in the summer, maintenance of the high temperature environment of the first space 11 for rearing the young chick C1 and cooling of the second space 12 for rearing the adult chicken C2 and cooling of the drinking water can be achieved simultaneously. It can be used effectively.

  Next, the winter season will be described with reference to FIG. In FIG. 4, a thick black line indicates the circulation path of the first medium.

  In the winter season, it is preferable to make the inside of the poultry house 10 a high temperature environment so that both the juvenile chick C1 and the adult chicken C2 can cope with the rapid drop in the outside air temperature.

  In the winter season, the switching valve 28 shown in FIG. 2 is switched to connect the first flow passage 21a and the third flow passage 21c, and as shown in FIG. 4, only the heat can be taken out from the heat pump 20. For this reason, the second medium circulating to the cooling path 40 is not cooled by the cold water heat exchanger 25. Further, the switching valves V3 and V4 are switched to connect the second heating path 32 and the connection path 45.

  As a result, the first heating path 31 can warm the inside of the first space 11 from under the floor of the first space 11. Therefore, a suitable nursery environment can be provided to the young chick C1.

  On the other hand, the gas heat exchanger 50 can supply the heat from the first medium into the second space 12 by the fan F2, and can warm the inside of the second space 12. Further, the water supply pipe heat exchanger 70 can warm the drinking water in the second water supply pipe 62 by the heat from the first medium. Therefore, a suitable rearing environment can be provided to adult chicken C2.

  In the middle of a season such as spring or fall, the above-mentioned summer mode and winter mode are appropriately switched according to the temperature of the day. The dehumidifier 51 can appropriately switch and use the dehumidifying function shown in FIG. 3 in the on state and the dehumidifying function shown in FIG. 4 in the off state according to the humidity in the first space 11.

  As described above, the poultry farming system 1 according to the present embodiment includes the chicken house 10 in which chickens are raised, the heat pump 20 capable of simultaneously extracting cold heat and heat, and the first medium heated by the heat extracted from the heat pump 20 And a heating path 30 for heating the chicken house 10 and drinking water, and a cooling path 40 for cooling the poultry house 10 and drinking water by circulating a second medium cooled by cold heat extracted from the heat pump 20. And. The heat pump 20 includes a first flow passage 21a, a second flow passage 21b, and a third flow passage 21c. The second flow passage 21b and the third flow passage 21c are branched from the first flow passage 21a, and the first flow passage While being comprised so that 21a may merge, it has the refrigerant | coolant flow path 21 which a refrigerant | coolant circulates. In addition, the heat pump 20 is provided in the first flow passage 21 a, and compresses the refrigerant passing through the first flow passage 21 a to expand the temperature of the refrigerant, and expands the refrigerant to decrease the temperature of the refrigerant. And an expansion valve 23. Further, the heat pump 20 is provided in the first flow passage 21a, and is provided in the hot water heat exchanger 24 for heating the first medium by the refrigerant circulating from the compressor 22 toward the expansion valve 23, and provided in the second flow passage 21b. And a cold water heat exchanger 25 for cooling the second medium by a refrigerant circulating from the expansion valve 23 toward the compressor 22. Further, the heat pump 20 is provided in the third flow path 21 c, and the air heat exchanger 26 for cooling the air taken in from the outside by the refrigerant circulating from the expansion valve 23 toward the compressor 22; And the switching valve 28 for switching the supply of the refrigerant passing through the first flow passage 21a to the second flow passage 21b or the third flow passage 21c.

  According to the poultry farming system 1 configured as described above, the electric heat pump 20 is used as a heating power source without using a fossil fuel bleeder device or a boiler. Therefore, the emission of carbon dioxide can be suppressed. The first medium circulating through the heating path 30 heats the drinking water supplied to the poultry house 10 and the livestock, and the second medium circulating through the cooling path 40 cools the drinking water supplied to the poultry house 10 and the livestock. Therefore, depending on the season, heating and cooling of the poultry house 10 can be switched, and heating and cooling of drinking water supplied to the chicken can be switched. Therefore, it is possible to provide a chicken with a suitable breeding environment. From the above, it is possible to provide a poultry farming system 1 capable of giving a suitable breeding environment to chickens while considering the environment.

  In addition, the poultry farming system 1 is provided in the connecting path 45 connectable to the heating path 30 and the cooling path 40, and the connecting path 45, and heats the inside of the poultry house 10 by the first medium circulating the heating path 30, or the cooling path 40 A gas heat exchanger 50 for cooling the inside of the chicken house 10 by the second medium circulating the water, and the connecting path 45, and heating the drinking water by the first medium circulating the heating path 30 or circulating the cooling path 40 (2) A feed pipe heat exchanger 70 for cooling drinking water with a medium. The heating path 30 is arranged to pass under the floor of the poultry house 10. According to the poultry farming system 1 configured as described above, it is possible to provide a chicken with a more suitable breeding environment.

  The chicken house 10 has a first space 11 in which the young chick C1 resides, and a second space 12 in which the adult chicken C2 resides, and the gas heat exchanger 50 is disposed in the second space 12 and is heated The path 30 is disposed to pass only under the floor of the first space 11. According to the poultry farming system 1 configured in this manner, a space for raising the young chick C1 and a space for raising the adult chicken C2 can be divided.

  For example, in a conventional poultry house, 10,000 birds per house are put on average in the state of juvenile chick C1, and shipped as adult chicken C2 in 48 days. After that, cleaning, sterilization and drying are performed in 12 days, and a total of 60 days are nurtured in one cycle. Therefore, we make 6 rotations a year and produce 60000 birds / year. On the other hand, in the poultry farming system 1 according to the present embodiment, the first space 11 in which the young chick C1 resides and the second space 12 in which the adult chicken C2 resides are divided. Here, first, the young chick C1 is reared in the first space 11 for 21 days. Thereafter, chickens reared for only 21 days in the first space 11 are moved to the second space 12 and reared for 28 days in the second space 12, and then shipped as adult chickens C2. Thereafter, in the second space 12, cleaning, sterilization and drying are performed for 12 days. For this reason, the utilization period of the second space 12 can be made 28 days plus 40 days of 12 days, and can be rotated nine times a year. Therefore, it is possible to produce 90,000 birds / year and improve the productivity. In addition, according to the scale of a poultry house, the breeding number mentioned above can be changed suitably.

  Moreover, the sterilizer 80 which disinfects the inside of the poultry house 10 is further provided, and the sterilizer 80 is an excimer lamp. According to the poultry farming system 1 configured as described above, the growth of the young chick C1 can be safely promoted by realizing a comfortable feeding environment.
