Description

System for converting cooling and heating using seawater heat pump

The present invention relates to a cooling / heating switching system using a seawater heat heat pump, and more particularly, to a seawater heat heat pump that controls and supplies a temperature of water to be stored in a facility such as a water tank by using sea water as a heat source of a heat pump. It relates to a cooling and heating switching system used.

Heat pump is a cooling and heating device that transfers a low temperature heat source to a high temperature or heats a high temperature heat source to a low temperature by using heat of a refrigerant or condensation heat.It is widely used as a cold / hot heat production device that uses geothermal and water heat according to a new renewable energy supply policy. have.

When water is used as a heat source of a heat pump, water of a water temperature lower than the atmospheric temperature can be used for cooling and water of a water temperature higher than the atmospheric temperature can be used for heating, so the water heat is excellent as a heat source of the heat pump.

In order to use water (sea water, river water) as a heat source of the heat pump, it is necessary to install a filter and a heat exchanger so that the heat pump can be easily maintained without being affected by the water quality or physical properties of the heat pump. Furnace should be made as a heat exchanger. In addition, the water intake system is very important in the system using water heat, and check and management measures are required to secure the design flow rate. By installing a filter for water used for heat exchange, it is possible to prevent foreign substances such as organisms from adhering to the heat exchanger plate and to reduce the heat exchange efficiency. However, the maintenance and operation of the filter requires power.

On the other hand, most farms and sashimi have adopted a business method in which a large amount of fish and shellfish is stored at high density together with water inside a tank forming a relatively narrow space, and then taken out and sold as needed.

When a large amount of fish and shellfish are stored in high density in a tank forming a narrow space, when a large amount of fish and shellfish are stored, dissolved oxygen contained in the water is rapidly consumed, and various foreign matters, proteins, ammonia, Nitrogenous components accumulate in the water at high concentration in a short time, and this causes the water quality in the tank to deteriorate rapidly. do. This phenomenon is closely related to the temperature in the bath.

The fish and shellfish stored in the tank should maintain the proper water temperature according to the characteristics of the fish and shellfish. In the case of cold water fish, the chilled water is cooled by using a cooler, and in the case of temperate or subtropical fish, an electric heater is used to raise the water temperature. It is common to raise the water temperature. In particular, in summer, the water temperature of the tank rises due to the high external temperature, and the fish that requires a water temperature of around 10 degrees Celsius dies. In winter, when the external temperature is low, the water temperature drops to below freezing, so the temperature is controlled in the tank. It is an important part of management.

However, in order to lower the water temperature of 1 degree Celsius, it is inevitable to operate a cooler for a long time, and the operation of the compressor is hindering the living environment by generating noise and vibration and hot air. In addition, the freon gas used as a refrigerant pollutes the air environment and destroys the ozone layer. Therefore, the necessity of an alternative device is urgently needed. In addition, the electric heater method used as a method of raising the water temperature stored in the water tank in winter is the difference in water temperature around the heater. It is so severe that it puts considerable stress on fish that are very sensitive to water temperature and the power consumption cannot be overlooked. In addition, a conventional cooler and heater have a inconvenience of having to repeat the installation and removal according to the season.
