Description of the Related Art In recent years, research and experiments on cultivation and fishing of marine and marine resources such as fish and shells inhabiting the ocean have been active. Along with this, research and experiments on commercial production scale in aquaculture, such as aquaculture and seed production,
There is a tendency to adopt an artificial production method using a breeding aquarium using a large amount of seawater.

In the summer, the water is cooled by a refrigerator to maintain a predetermined water temperature.

When it is used as production water, it is mixed with surface water in summer and heated to a water temperature suitable for the growth of these fish and the like.

が要望されていた。In the case of producing marine organisms using only surface water, the amount of water used is large. Therefore, the energy cost of a water temperature control system using a boiler or a refrigerator is enormous. In addition, cooling is not performed in practice because of the high energy cost required for cooling. Therefore, mortality of breeding organisms due to a rise in water temperature in summer has become a serious problem. For this reason, there has been a demand for the development of a water temperature control system which has low energy costs and is economical.

となる同様の問題を孕んでいる。Further, since the water temperature control of the deep water is a method of adjusting the mixing of the deep water and the surface water, the mixing ratio of the deep water and the surface water changes according to the season, thereby impairing the cleanliness of the deep water. In addition, because there is a problem that nutrients contained in deep water are also diluted, experimental research on water quality etc.,
In the production of algae, the use of deep water alone is an essential requirement. Therefore, a method of controlling the temperature of deep water that does not mix deep water and surface water has been required. Although cooling by a refrigerator is conceivable, it has the same problem that the energy cost described above increases.

水の冷却が適宜に行えることが分かる。The table shows that the use of only a heat exchanger throughout the year is sufficient if both the deep water and the surface water require a temperature level of 15 ° C. If both the deep water and the surface water require a temperature level of 18 ° C.,
Heat exchangers are used from January to mid-December for surface water until January, and heat pumps are operated during January-May and December for deep water. It runs on water from January to mid-April. Further, if both the deep water and the surface water require a temperature level of 23 ° C., the heat exchanger is used from August to mid-September for the deep water and from July to October for the surface water. And a heat pump is used for deep water.
Driving from Mon to July, and mid-September to December, for surface water from January to June, and November, 1
Drive in February period. From this, it can be seen that according to the water temperature control system of the present embodiment, heating of the deep water and cooling of the surface water can be appropriately performed by using the heat exchanger alone or by using the heat exchanger and the heat pump together.

比しほぼ２分の１以下になると予測される。FIG. 4B shows the system of the present embodiment required for controlling the water temperature, the heating by the boiler, and the cooling by the refrigerator, assuming that the water temperature control is performed under the temperature level conditions shown in FIG. It shows a comparison graph of the energy consumption required for heating or cooling per unit water amount with the conventional system that performs cooling. The hatched portion indicates the energy consumption by the conventional system, and the black background portion indicates the energy consumption by the system of the present embodiment. Is shown. From this graph, the energy consumption of both systems is the same in January, but the energy consumption of this embodiment in February to July and October to December is much smaller than that of the prior art. In addition, it can be seen that the difference appears remarkably in August and September. From this, it is expected that the energy consumption of the water temperature control system according to the present embodiment will be approximately one half or less of that of the conventional system.

とが出来る。As described above, according to the present invention, deep water and surface water having a higher temperature than the deep water are supplied to the heat exchanger, and the outlet water temperature of the surface water after the heat exchange is detected. While controlling the flow rate of deep water from the three-way valve to the heat exchanger based on the detected value to discharge the surface water cooled to a predetermined water temperature, a part of the surface water is branched to form a heat pump. And the preheated deep water after heat exchange is sent to the condenser of the heat pump, the temperature of the deep water at the outlet of the condenser is detected, and the heat pump is started according to the detected value to condense the water. Since it is configured to obtain the deep water heated from the vessel and the cooled surface water from the evaporator, not only the cooled surface water but also the heated deep water is separately obtained as production water. I can do it. Moreover, since the deep water is fed to the heat exchanger or the condenser and heated, the deep water is obtained without deteriorating the cleanliness of the deep water itself without changing the water quality. I can do it.

It is possible to obtain surface water and deep water having a set water temperature level by selectively operating the heat pump and heat pump, or switching to an operation mode using combined operation, which significantly reduces the energy consumption required for cooling and heating. It becomes possible to reduce to.
