The present invention relates to a water tank equipment system for live crustaceans using a heat exchange water tank. The water tank equipment system includes: a seawater storage tank into which filtrated seawater is inserted； the heat exchange water tank which allows the seawater, stored in the seawater storage tank, to be inserted therein, re-collects coldness and heat of waste water, and exchanges heat； a cooling apparatus which allows the seawater, after heat exchange in the heat exchange water tank, to be inserted therein and produces cooling water by performing a cooling process on the seawater； a cooling water storage tank which stores the cooling water on which the cooling process has been performed by the cooling apparatus； a water tank which stores live crustaceans at low temperatures as the cooling water, stored in the cooling water storage tank, is supplied； a waste water storage tank which stores waste water discharged from the water tank； and a heat exchange transferring pipe installed in the heat exchange water tank to make the seawater in the heat exchange water tank re-collect coldness and heat of the waste water while the waste water, stored in the waste water storage tank, is discharged. Therefore, coldness and heat of the waste water is recollected with high efficiency through the heat exchange water tank； the cooling water is continuously supplied at low costs； and environment pollution can be prevented by significantly reducing the mortality amount of crustaceans.본 발명은 열교환수조를 이용한 활 갑각류 보관용 수조설비 시스템에 관한 것으로, 여과된 해수가 유입되는 해수 보관탱크와, 상기 해수 보관탱크에 저장된 해수가 유입되며, 폐수의 냉열을 회수하여 열교환을 하기 위한 열교환수조와, 상기 열교환수조에서 열교환이 이루어진 해수가 유입되어 냉각과정을 거쳐 냉각수를 생성하는 냉각장치와, 상기 냉각장치에서 냉각과정을 거친 냉각수가 저장되는 냉각수 보관탱크와, 상기 냉각수 보관탱크에 저장된 냉각수가 공급되어 활 갑각류를 저온으로 보관하는 수조와, 상기 수조에서 버려지는 폐수가 저장되는 폐수 저장탱크와, 상기 폐수 저장탱크에 저장된 폐수가 배출되면서 상기 폐수의 냉열을 상기 열교환수조의 해수가 회수하도록 상기 열교환수조 내부에 설치되는 열교환 이송관을 포함함으로써, 폐수의 냉열을 열교환수조를 통하여 고효율로 회수하여 저렴한 비용으로 냉각수의 연속공급이 가능하도록 하고, 폐사량을 획기적으로 줄여 환경 오염을 방지할 수 있는 효과가 있다
