SYSTEM FOR CONTROLLING WATER TEMPERATURE OF NURSERY

摘要

PURPOSE: A system for controlling water temperature of a nursery is provided, which stimulates the growth of fish and increases the income by exchanging the water in the nursery with fresh water containing enough dissolved oxygen and by maintaining the water temperature to be 15-20deg.C. CONSTITUTION: The system for controlling water temperature of a nursery comprises: a first heat exchanging part(10) transporting the subterranean water to a second heat exchanging part(20) and the water in the nursery to a third heat exchanging part(30) after heat-exchanging the water in the nursery and the subterranean water to be 10-20deg.C; a second heat exchanging part(20) heat-exchanging the same subterranean water to be 25-30deg.C and having a heat discharging pipe(21) discharging the same water to the nursery; and a third heat exchanging part(30) having a coolant pipe(31) making the same water cooled to be 6-8deg.C by the cool air.
