Description

Technical Field

[0001] The utility model relates to the technical field of kelp seedling breeding, in particular to an ammonia compression cooling device for kelp seedling breeding. Background Technique

[0002] Kelp is a perennial large edible alga. Kelp is rich in kelp polysaccharides, and three kinds of polysaccharides have been found so far: alginate, fucoidan, and laminarin. It also contains various active ingredients such as acidic polysaccharide substances, fucogalactan disodium, zosterin, galacturonic acid, laminine, taurine, and bifidogenic factors.

[0003] During the process of kelp seedling breeding, it is necessary to strictly control the water temperature in the seedling rearing pond to avoid the water temperature in the pond being too high or too low, which will affect the normal growth of kelp seedlings or even cause death. When the water temperature in the seedling rearing pond is relatively high, usually part of the pond water is pumped out and sent into the cooling device for cooling, and the cooled pond water is discharged back into the seedling rearing pond and mixed with the pond water to achieve the cooling of the pond water in the seedling rearing pond. The ammonia compression cooling device is a commonly used cooling device. When the commonly used ammonia compression cooling device cools the pond water, it absorbs the heat of the pond water by contacting the pond water with the evaporator, but the pond water cannot directly contact the surface of the evaporator, resulting in limited cooling efficiency of the pond water.
