Description

Technical Field

[0001] This utility model relates to the field of heating technology for aquaculture containers, and in particular to a system for the coordinated utilization of water resources in aquaculture farms. Background Technology

[0002] In industrialized shrimp farming, precise water temperature control is crucial for ensuring the healthy growth of shrimp. Currently, submersible electric heaters are commonly used in shrimp farms for water temperature regulation. However, this technology has revealed the following shortcomings in practical applications:

[0003] (1) Ecological risks caused by metal pollution

[0004] The metal casing of electric heating rods is constantly immersed in high-salinity seawater, causing the continuous leaching of heavy metal ions such as nickel and chromium. This accumulation of metals not only inhibits the development of shrimp larvae's shells but also threatens food safety at the end of the food chain. Farms are forced to perform additional weekly water changes to dilute pollutants, significantly increasing water resource and wastewater treatment costs.

[0005] (2) Scaling effect reduces thermal efficiency

[0006] Calcium and magnesium ions in seawater form a carbonate scale layer on the surface of the heater, and this phenomenon worsens exponentially with operating time. To maintain the target water temperature, the system's energy consumption needs to be increased, significantly driving up aquaculture costs.

[0007] (3) Systemic contradictions in heat source selection

[0008] While existing heat pump technology has a high energy efficiency ratio, heat exchangers also suffer from corrosion and scaling problems in seawater environments. Solar heating is limited by diurnal and seasonal fluctuations, requiring large-capacity hot water storage tanks, which not only occupy a large area but also require supplemental electric heating in cold weather.

[0041] Specifically, aquaculture area 9 can be used as an aquaculture area, such as a shrimp farming area. When the water in shrimp farming area 9 is not changed, the medium-deep geothermal system is activated to connect the ground source heat pump unit 6 with the water heating system of shrimp farming area 9, so as to fully absorb geothermal energy and maintain the water temperature of shrimp farming area 9 unchanged.

[0042] When the water in shrimp farming area 9 is replaced, the water storage tank 10 is connected to the water in shrimp farming area 9 to replace the water in shrimp farming area 9.
