Description

Semi-flooded package type Heat pump unit equipment use Seawater Heat pump system}

The present invention relates to a seawater heat source heat pump system using a half-liquid package type heat pump unit device, and more particularly, to evaporate by securing a time and amount of refrigerant to allow a sufficient amount of refrigerant to evaporate by heating a heat pipe of an evaporator in a seawater heat source tank. The increase in performance is improved, and the recovery tube is inserted into the heat transfer tube to easily recover the liquid refrigerant in the heat transfer tube generated in the structure converted from the evaporator to the condenser during cooling, and the heat transfer tube uses a seamless titanium pipe. Low leakage, easy to replace when the heat pipe is defective, cost is reduced, and the seawater heat pump of the package at the factory shipment by integrating the components of the seawater heat tank, cold and hot water heat exchanger, compressor, etc. in one unit Factory delivery eliminates the need for a separate refrigerant cycle on site Installation time and installation cost can be reduced, and the hot water side is equipped with a plate heat exchanger to store the high temperature in the hot water tank to meet the required temperature conditions in the aquaculture process, thus increasing the efficiency of the seawater heat source heat pump system. A seawater heat source heat pump system using a liquid package type heat pump unit device.

In winter, the temperature of coastal seawater is lowered, which reduces the performance of the heat pump.

Due to the clogging phenomenon of the heat exchanger, which is a chronic problem of the conventional double tube evaporator, there is a problem of poor performance and short durability of the equipment.

This requires a semi-liquid evaporator that can be easily cleaned and improves the evaporator's performance to improve efficiency even at low temperatures.

The land tank farming method is a technology that is widely used by fishermen because it is convenient to supply appropriate water temperature according to abundant water sources and fish species.

From hatching of eggs to seed production in the aquaculture process, the following process is largely carried out.

① Exponential cultivation: When the temperature of water is maintained without supplying water in the tank. (Load process 1st and 2nd metamorphosis of eggs.)

② Flow-type culture: When water is supplied as needed at a constant temperature. (Seedling time)

In conventional aquaculture processes, heat pumps used a boiler or electric heater to control the temperature during exponential culture. Therefore, the existing heat pump can be used only for the aquaculture process, so it is necessary to install and use a facility that uses electricity or oil.

As such, the tank farming method is a technology that is now widely used by fishermen because it is convenient to supply the proper water temperature according to the rich water source and fish species.

By the way, the land tank farming method is to raise the sea water directly from the sea to be adjusted to a temperature suitable for aquaculture and then to supply the tank to the water quality and temperature control of the supply water is the most important problem.

In other words, the coastal waters of Korea have caused red tide phenomena from around May every year, causing enormous damage to the aquaculture industry. Also, the changes in the water supply temperature caused by the rapid change in seawater temperature caused the fish to die or slow down the growth rate. It is a factor that greatly reduces.

For example, in the case of halibut farming, the optimum growth temperature is 17 ℃ to 19 ℃. Therefore, even if the temperature of the water supply is only 21 ℃, malformation occurs in the seedling culture in the tank and the growth rate of the fry is about 50% lower than the optimum growth temperature.

In addition, inappropriate water temperature also lowers the biodefense ability of the fry, resulting in fish disease. In addition, according to the research report, there is a difference in the food intake of the fry according to the change in water temperature, which affects the growth rate. For example, flounder, which grows optimally at 17 ° C, has slowed significantly at low temperatures (about 14 ° C) and only eats about half of its diet at 15 ° C at high temperatures (about 20 ° C and above).

As such, the temperature of the seawater in the tank has a significant effect on the growth of the fish. Accordingly, in the winter when the water temperature is lower than the optimum temperature, the sea water is heated by the boiler and supplied to the tank, or in the summer, the hot water is exchanged with the groundwater of the relatively low temperature to reduce the water supply to the appropriate temperature, and then supply it to the tank. Although these methods are used, these conventional methods are not only costly and low in energy efficiency, but also cannot be used in areas where geological groundwater cannot be produced.

For example, using a boiler to increase the seawater temperature in winter is excessively expensive to raise the water supply temperature, which is not profitable for small fishers, and heats relatively hot seawater with relatively low groundwater in summer. The method of lowering the water supply temperature is not suitable when the water supply temperature must be raised to 15 ° C. or higher because the ground water maintains a low temperature of about 15 ° C. in general.
