  On the other hand, 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 second medium cooled by the cold water heat exchanger 25 flows through the connection path 45.

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

  The gas heat exchanger 50 is disposed in the first connection path 46. Next to the gas heat exchanger 50, a fan F2 is arranged. By connecting the second heating path 32 and the connection 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 supplied. For example, it can be heated to 20 to 35 ° C.

For example, cold air of 10 to 20 ° C. can be supplied.

  The dehumidifier 51 adjusts the humidity in the first space 11. The dehumidifier 51 is disposed in the first pipe 55 and the second pipe 56. Next to the dehumidifier 51, a fan F1 is arranged. When the function of the dehumidifier 51 is turned on, the switching valve V1 turns on the supply of the first medium passing through the second heating path 32 to the dehumidifier 51, and the switching valve V2 has a cooling path 40. The supply of the second medium passing through to the dehumidifier 51 is turned on (see FIG. 3). The air in the vicinity of the dehumidifier 51 is cooled by the second medium, and the moisture is changed into water droplets to be condensed and eliminated, so that the dried 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 at the switching valve V1, and the cooling is performed at the switching valve V2. 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 draws 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 for supplying water to the young chick C1, and a second water supply pipe 62 provided in the second space 12 for supplying water to the adult chicken C2.

  The water supply pipe heat exchanger 70 is disposed in the second connection path 47. The water supply pipe heat exchanger 70 is disposed adjacent to the second water supply pipe 62. By connecting the second heating path 32 and the connection path 45 in the switching valves V3 and V4, the first medium flows in the second connection path 47.

  The water supply pipe heat exchanger 70 can warm the drinking water flowing through the second water supply pipe 62 to, for example, 30 ° C. by the heat of the first medium. On the other hand, the second medium flows through the second connection path 47 by connecting the cooling path 40 and the connection path 45 in the switching valves V3 and V4. The water supply pipe heat exchanger 70 can cool the drinking water flowing through the second water supply pipe 62 to, for example, 10 to 20 ° C. by the cold heat of the second medium.

  The sterilizer 80 is provided in the first space 11 and sterilizes the first space 11. As the sterilizer 80, for example, an excimer lamp can be used. Thus, by using an excimer lamp as the sterilizer 80, diffusible ozone and radicals are generated, sterilization and virus growth can be suppressed, and the deodorizing effect on odor and ammonia can be enhanced. Therefore, by realizing a comfortable environment, the growth of the young chick C1 can be promoted safely. Note that a discharge type ozonizer may be used as the sterilizer.

  The control unit 90 controls switching of the switching valve 28, the switching valve V1, the switching valve V2, the switching valve V3, and the switching valve V4. The control unit 90 is, for example, a CPU. 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 for raising chickens by the chicken raising system 1 according to this embodiment will be described. Hereinafter, the method for raising chickens by the chicken raising system 1 will be described separately for the summer and winter seasons.

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

  In summer, due to the recent warming, the temperature in the poultry house 10 suddenly rises, and thermal death of the adult chicken C2 frequently occurs. For this reason, while cooling the 2nd space 12 where adult chicken C2 is reared, it is necessary to cool the drinking water of adult chicken C2. In contrast, the young chick C1 is preferably in a higher temperature environment than the adult chicken C2.

  In the summer, the switching valve 28 shown in FIG. 2 is switched to connect the first flow path 21a and the second flow path 21b so that the heat and cold can be taken out from the heat pump 20 simultaneously as shown in FIG. 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 rearing environment can be provided for the young chick C1.

  On the other hand, the gas heat exchanger 50 can supply the cold heat from the second medium into the second space 12 by the fan F2, and can cool the second space 12. Further, the water supply pipe heat exchanger 70 can cool the drinking water in the second water supply pipe 62 by the cold heat from the second medium. Since adult chicken C2 has no sweat glands and is covered with feathers, body temperature cannot be adjusted by sweating, and heat is not easily dissipated, and heat tends to be trapped in the body. For this reason, body temperature adjustment cannot catch up if there is a sudden rise in the outside air temperature. Moreover, the adult chicken C2 has a characteristic that drinks more water than other organisms. For this reason, the adult chicken C2 can suitably adjust the body temperature of the adult chicken C2 by drinking the drinking water cooled by the cold heat from the second medium. Therefore, a suitable breeding environment can be provided for the adult chicken C2.

  In this way, in the summer, the maintenance of the high temperature environment of the first space 11 for raising the young chick C1 and the cooling of the second space 12 for raising the adult chicken C2 and the cooling of drinking water can be achieved simultaneously. Effective utilization can be achieved.

  Next, with reference to FIG. 4, the case of winter will be described. In FIG. 4, black thick lines indicate the circulation path of the first medium.

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

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

  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 rearing environment can be provided for 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 heat 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 breeding environment can be provided for the adult chicken C2.

  In an intermediate period such as spring or autumn, the summer mode and the winter mode described above are appropriately switched according to the temperature of the day. Further, the dehumidifier 51 can be used by appropriately switching between the state where the dehumidifying function shown in FIG. 3 is on and the state where the dehumidifying function shown in FIG. 4 is off according to the humidity in the first space 11.

  As described above, the poultry farming system 1 according to the present embodiment includes the poultry house 10 where the chickens are raised, the heat pump 20 that can simultaneously extract cold and hot heat, and the first medium that is heated by the hot heat that is extracted from the heat pump 20. Circulates the heating path 30 for heating the poultry house 10 and the drinking water, and the cooling path 40 for cooling the poultry house 10 and the drinking water by circulating the second medium cooled by the cold heat extracted from the heat pump 20. Have. The heat pump 20 includes a first flow path 21a, a second flow path 21b, and a third flow path 21c. The second flow path 21b and the third flow path 21c are branched from the first flow path 21a and the first flow path. The refrigerant flow path 21 is configured to merge with the refrigerant 21a and in which the refrigerant circulates. Further, the heat pump 20 is provided in the first flow path 21a, compresses the refrigerant passing through the first flow path 21a, and increases the temperature of the refrigerant, and expands the refrigerant to lower the temperature of the refrigerant. And an expansion valve 23 to be operated. The heat pump 20 is provided in the first flow path 21a, and is provided in the second flow path 21b and the hot water heat exchanger 24 that heats the first medium by the refrigerant circulating from the compressor 22 toward the expansion valve 23. And a chilled water heat exchanger 25 that cools the second medium by the refrigerant circulating from the expansion valve 23 toward the compressor 22. The heat pump 20 is provided in the third flow path 21c, and an air heat exchanger 26 that cools air taken in from the outside by a refrigerant that circulates from the expansion valve 23 toward the compressor 22, and an air heat exchanger 26. And a switching valve 28 that switches the supply of the refrigerant passing through the first flow path 21a to the second flow path 21b or the third flow path 21c.

  According to the poultry farming system 1 configured as described above, the electric heat pump 20 is used as a heating power supply without using a bleeder device or a boiler using fossil fuel. For this reason, discharge of carbon dioxide can be suppressed. The first medium circulating in the heating path 30 heats drinking water supplied to the chicken house 10 and the livestock, and the second medium circulating in the cooling path 40 cools drinking water supplied to the chicken house 10 and the livestock. For this reason, according to a season, while heating and cooling of the chicken house 10 can be switched, heating and cooling of the drinking water supplied to a chicken can be switched. Therefore, a suitable rearing environment can be given to the chicken. From the above, while considering the environment, it is possible to provide the chicken raising system 1 that can provide a suitable rearing environment for chickens.

  In addition, the poultry farming system 1 is connected to the heating path 30 and the cooling path 40, and is provided in the connecting path 45 and warms the poultry house 10 with the first medium circulating in the heating path 30, or the cooling path 40. A gas heat exchanger 50 that cools the inside of the poultry house 10 with a second medium that circulates and the connection path 45, and the first medium that circulates the heating path 30 heats drinking water or circulates the cooling path 40. And a water supply pipe heat exchanger 70 for cooling drinking water with two media. The heating path 30 is arranged so as to pass under the floor of the poultry house 10. According to the poultry farming system 1 configured as described above, a more suitable rearing environment can be given to the chicken.

  Moreover, the poultry house 10 has the 1st space 11 in which the young chick C1 lives, and the 2nd space 12 in which the adult chicken C2 lives, and the gas heat exchanger 50 is arrange | positioned in the 2nd space 12, and is heated. The path 30 is arranged so as to pass only under the floor of the first space 11. According to the poultry farming system 1 configured as described above, a space for raising the young chick C1 and a space for raising the adult chicken C2 can be separated.

  For example, in a conventional poultry house, an average of 10,000 chicks in the state of young chicks C1 is shipped as adult chicken C2 in 48 days. Thereafter, cleaning, sterilization, and drying are performed in 12 days, and a total of 60 days are nurtured in one cycle. Therefore, 6 000 birds / year are produced by rotating 6 times a year. On the other hand, in the poultry farming system 1 according to the present embodiment, it is divided into a first space 11 in which the young chick C1 resides and a second space 12 in which the adult chicken C2 resides. Here, the young chick C1 is first raised in the first space 11 only for 21 days. Thereafter, chickens raised in the first space 11 for only 21 days are moved to the second space 12, and after being raised in the second space 12 for 28 days, they are shipped as adult chickens C2. Thereafter, cleaning, sterilization, and drying are performed in the second space 12 in 12 days. For this reason, the utilization period of the second space 12 can be 28 days plus 40 days of the 12th, and can be rotated nine times a year. Therefore, 90000 birds / year can be produced, and productivity is improved. In addition, according to the scale of a poultry house, the breeding number mentioned above can be changed suitably.

  Moreover, it has further the sterilizer 80 which sterilizes the inside of the poultry house 10, 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 promoted safely by realizing a comfortable rearing environment.

  In the above-described embodiment, one poultry house 10 is provided in the poultry farming system 1, and the first space 11 in which the young chick C1 is nurtured and the second space 12 in which the adult chicken C2 is bred in one poultry house 10. Was configured.

  On the other hand, the poultry farming system 2 according to the modified example 1 has a plurality of (for example, five) poultry houses 10 as shown in FIG. In the plurality of chicken houses 10, chickens having different ages live. In addition, a gas heat exchanger 50 that adjusts the temperature in the chicken house 10 and a water supply pipe heat exchanger 70 that adjusts the temperature of drinking water supplied to the chicken are arranged in each of the plurality of chicken houses 10. The heating path 30 is disposed so as to pass under the floors of the plurality of poultry houses 10.

  According to the chicken farming system 2 configured as described above, the temperature in the chicken house 10 is adjusted or the temperature of the drinking water of the chicken is adjusted according to the age and season of the chickens living in each chicken house 10. Can do.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims.

  For example, in the above-described embodiment, the present invention is applied to a chicken raising system for raising chickens as a livestock barn system, but can also be applied to raising pigs and the like.

  Moreover, in embodiment mentioned above, although the chicken heat system 1 was provided with both the gas heat exchanger 50 and the feed water heat exchanger 70, one of the gas heat exchanger 50 and the feed water heat exchanger 70 is provided. It may be done.

  Moreover, in embodiment mentioned above, it partitioned off between the 1st space 11 and the 2nd space 12 so that the young chick C1 and the adult chicken C2 cannot come and go mutually. However, the first space 11 and the second space 12 may not be partitioned. Even if it is not partitioned, if the heating path 30 is disposed only under the first space 11, the young chicks C1 gather on the heating path 30. As a result, the adult chicken C2 lives in the second space 12, which is a space other than the first space 11, and the young chick C1 and the adult chicken C2 are classified by the space.
