Description
The present invention relates to a water temperature control device of a heat pump heat exchanger used to heat or cool the temperature of live fish water supplied to a fish tank for a fish farm, and a small amount of sample from the live fish water discharge pipe discharged to the tank side through a heat exchanger. While extracting and storing them in the sampling tank, while the live fish stored in the sampling tank is recovered to the discharge pipe in proportion to its inflow, the live fish extracted from the discharge pipe and the live fish stored in the sampling tank are mixed at a predetermined ratio. Unlike the conventional case of controlling the compressor by installing a sensor in the live water discharge pipe by measuring the temperature of the mixed live fish or by measuring the temperature of the live fish stored in the sampling tank to control the compressor of the heat pump device, By using the temperature of the live fish, which is leveled in the sampling tank, The present invention relates to a water temperature control apparatus for fish farm heat pumps that allows accurate temperature control and at the same time maintains the cycle cycle of the compressor gently to prevent failure or malfunction of the compressor.
In general, fish farms that farm various kinds of fish raise the temperature of the live fish in the winter season and send it to the culture tank, while in the summer, the live fish is cooled and sent to the culture tank, whereby the temperature of the live fish stored in the culture tank is stored. It is necessary to maintain the level suitable for the farming. Especially, the freshly hatched young fry is very sensitive to the water temperature, so precise water temperature management of ± 0.1 ℃ is required. However, heat pump devices having excellent energy saving effect using air heat sources are widely used.
Various types of heat pump devices used in fish farms and the like as described above are known, but as the most representative example, as shown in FIG. 1A, the

It will be described by integrating into the heat

As described above, even if the discharge capacity of the refrigerant is variablely controlled by using an inverter controlled or screw compressor, the temperature of the live fish stored in the fish tank is changed significantly by time, which is the fish farmed in the tank. By giving a lot of stress to the immunity to lower the immune system, the fish will be affected by various diseases, and in severe cases will cause serious problems leading to the death of farmed fish.
In particular, young fry, which are sensitive to changes in water temperature of 0.1 ℃, not only have a weak immunity due to the rapidly changing water temperature, but also hatcheries are usually installed on the land adjacent to the seashore, which draws seawater due to differences in low water. The amount of live fish is often changed according to the pump lift, and the temperature of the seawater also varies greatly depending on the day and night. Therefore, more precise temperature control is required for the safe farming of the fry. There was a problem that it was very difficult to breed the fry safely.
The present invention was devised to solve the above-mentioned conventional problems, the water temperature control device of the heat pump heat exchanger for fish farm according to the present invention, by extracting a small amount of samples from the live fish water discharge pipe discharged to the tank side through the heat exchanger While this is stored in the sampling tank for a certain time, while the live fish stored in the sampling tank is recovered to the discharge pipe in proportion to its inflow, the live fish extracted from the discharge pipe and the live fish stored in the sampling tank are mixed at a predetermined ratio. By measuring the temperature of the mixed live fish water by the water temperature sensor for compressor control or by measuring the temperature of the live fish water stored in the sampling tank by the water temperature sensor for compressor control, the compressor is installed in the live water discharge pipe to control the compressor. Unlike this, the temperature of the live fish is leveled in the sampling tank. This enables more precise and accurate temperature control, while keeping the cycle cycle of the compressor gentle to prevent compressor failure or malfunction, thereby minimizing the temperature deviation of the live fish supplied to the fish tank. By keeping the temperature of the live fish stored in the tank within a stable range, it prevents stress and disease and death of farmed fish in advance, and it is also safely applied to the culture of young fry, which is very difficult to manage. It is the technical task to make it possible.
As a means for solving the above technical problem, the water temperature regulating device according to the first embodiment of the present invention, the sampling line branched from the discharge pipe for supplying live fish water to the fish tank tank side through the heat pump heat exchanger, and the sampling line It includes a sampling tank for storing the live fish water introduced through, and a recovery line extending from the sampling tank connected to the discharge pipe, the discharge line is further extended from the sampling tank, the discharge line is It is connected to the sampling line to form a single water line, and the water line is extended to the sampling tank side and is connected to the sampling tank again. The water pump is installed in the water line and the water pump corresponding to the position past the sampling pump. For the control of the compressor in the alternative location of the line or sampling tank On characterized in that the sensor is installed, the valve the sampling line and the discharge line and is characterized in that the valve is respectively provided, it is characterized in that the flow control valve.
In addition, the water temperature control device according to the second and third embodiments of the present invention, as in the first embodiment, the sampling line branched from the discharge pipe for supplying live fish water to the fish tank tank side through the heat pump heat exchanger, Based on the sampling tank for storing the live fish water introduced through the sampling line and the recovery line extending from the sampling tank and connected to the discharge pipe, the sampling pump is installed in the sampling line or the sampling line and the recovery line Compressor is controlled by forming a shaft tube with a reduced diameter in the discharge pipe, which allows the live fish to flow directly from the sampling line to the sampling tank, and measures the leveled temperature of the live fish using the water temperature sensor installed in the sampling tank. It is characterized by all.
According to the present invention as described above, while the discharge capacity of the compressor is gradually changed in the inverter control type, hot gas bypass method or screw method, the upper and lower limits of the live fish water temperature stored in the culture tank, that is, the temperature deviation of the live fish water By being able to greatly reduce, it is possible to more precisely and precisely control the temperature of the live fish stored in the culture tank while preventing the compressor failure or malfunction.
As described above, the temperature deviation of the live fish stored in the fish farm is reduced to the maximum, and the temperature of the live fish is precisely and precisely controlled so that the temperature of the live fish stored in the fish farm is continuously maintained within a stable range. As can be, there is an effect to prevent disease and mortality of farmed fish due to stress caused by temperature deviation and a decrease in immunity caused by the temperature deviation in the fish tank.
Particularly, even when the quantity of live fish fluctuates frequently depending on the lift of the pump that draws seawater due to the difference in the water tide, or the temperature of seawater fluctuates greatly depending on the day and night, it is a miniature that reduces the environment of aquaculture tank as it is. Using the sampling tank as a model, it is effective to finely adjust the temperature of the live fish stored in the culture tank within the practical optimum range, which makes it possible to safely perform the farming of the fry which is weak in immunity and very difficult to manage. have.
