LIVING FISH TANK SYSTEM AND CHILLER FOR LIVING FISH TANK WATER

摘要

PURPOSE:To efficiently feed oxygen into a living fish tank by cleaning the circulating water in said tank with filters and a deaerating tank followed by chilling the water through a chiller and then injecting oxygen or air from a gas distributor into said circulating water. CONSTITUTION:The water in a living fish tank 1 is circulated with a circulating pump 5, and the circulating water is first introduced into filters 2 to remove solid floating matter, microorganisms, ammonia, odor, etc. The resultant circulating water is introduced into a deaerating tank 4 where the residual carbon dioxide dissolved in said water is removed. The resultant circulating water is brought, under pressure, to a chiller 6 where the water is chilled through a chilling coil 21 installed in the chiller 6, and at the same time, oxygen or oxygen-contg. gas is injected from a gas distributor 22 installed in said chiller 6 followed by circulating the resultant water into the living fish tank 1. Thereby, the tank 1 will be always filled with clean water with oxygen dissolved sufficiently and uniformly, thus living fishes being never weakened.
