Cooling device for spraying cold water into lobster culture trench applying chilled water made by solar energy

Abstract

The invention relates to a cooling device for spraying cold water into a lobster culture trench applying chilled water made by solar energy, belonging to the technical field of new energy refrigeration. Lithium bromide solution is used as an absorbent and water is used as a refrigerant for a solar-driven lithium bromide-water absorptive refrigerator; solar energy is used as a driving heat source; the driving heat source is directly or indirectly utilized in a unit for making chilled water and discharging cold air. The chilled water output from a chilled water tank is input into a booster pump for boosting through a chilled water delivery pipe; the boosted high-pressure chilled water is uniformly sprayed into the lobster culture trench through a high-pressure chilled water delivery pipe and a chilled water spray gun head, so that the water temperature in the lobster culture trench is reduced in the high-temperature season of summer, and the most proper growth temperature of lobsters is kept at 25-30 DEG C. The food intake of the lobsters is increased, and the growth speed of the lobsters is increased. Sunlight irradiates a solar cell to generate current; the current is input into a controller through a wire; the current which is output from the controller is used for providing power for the energy storage battery and the booster pump through wires.

Description

technical field [0001] The invention relates to a cooling device for spraying cold water into a lobster breeding ditch using solar energy-made frozen water, and belongs to the technical field of new energy refrigeration. Background technique [0002] In the past ten years, the domestic lobster farming scale and market consumption have increased a lot. Freshwater lobster originated in the United States and was introduced to China during World War II. The main breed of freshwater lobster is crayfish. Many lobster shops have appeared in the cities and market towns in the middle and lower reaches of the Yangtze River, selling a large amount of cooked lobster every year. Xuyi County, Jiangsu Province holds the International Lobster Festival every year, collecting 13 kinds of spice plants and steaming them together with lobsters to produce "Thirteen Flavored Lobsters", which is welcomed by the majority of diners and is well-known all over the country. Lobster is very popular in ...

Problems solved by technology

Young lobsters are not suitable for growing in water bodies above 30°C and below 5°C. The activity of phenoloxidase in the immune system of lobsters is best at a temperature of 20°C, and the suitable growth temperature of lobsters is 25°C. -30°C, when the water temperature exceeds 30°C, especially when the water temperature exceeds 35°C, the food intake of the lobster will decrease, which will affect the increase in the weight of the lobster, thereby affecting the production of the lobster
