Marine Seawater Cooling And Refrigeration Systems
Advanced marine cooling and refrigeration solutions designed for aquaculture, vessel operations, and industrial applications with precision temperature control and corrosion-resistant construction.
Core Specifications
- Cooling Capacity Range: Commercial models from 1 HP (approx. 2427W) to 5 HP (12kW+) for marine aquaculture and fishing operations
- Industrial Models: Air-cooled twin-screw units with capacities up to hundreds of kilowatts for large-scale seawater cooling systems
- Temperature Control Accuracy: ±1°C for aquaculture (e.g., oyster farming requires 10-25°C maintenance)
- Marine Aquarium Cooling: ±0.5°C precision (recommended 24-26°C range)
- Corrosion-Resistant Design: Pure titanium or stainless steel evaporators (e.g., Sensen UA-2.8DR model)
- Secondary Coolant: Seawater or brine (calcium chloride solution suitable for -40°C to 5°C)
- Energy Efficiency: Complies with GB/T18430.1 standards; certain models achieve COP (Coefficient of Performance) exceeding 3.5
Operating Principle
- Heat Pump Technology: Utilizes four-component cycle (compressor, condenser, expansion valve, evaporator) to transfer heat via seawater temperature differentials
- Seawater Integration: Seawater serves as heat source/sink, interacting with refrigerant through heat exchangers to achieve cooling or heating
- Aquaculture Applications: Built-in pump draws seawater → chiller cools → returns to aquaculture tanks, forming closed-loop circulation
- Industrial Capabilities: Industrial models handle -30°C brine for seafood rapid freezing
- Aquarium Process: Circulation pump feeds seawater into chiller tank → Compressor cools → Returned to main tank after cooling
- Efficiency Optimization: Recommended temperature differential of 2°C (e.g., start at 28°C, stop at 26°C) to minimize energy consumption
