Product Description
Marine Seawater Cooling & Refrigeration Systems
Advanced marine cooling and refrigeration solutions designed for aquaculture, vessel operations, and seafood processing applications.
Core Specifications
Cooling Capacity Range
- Commercial Models: 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
- Aquaculture: ±1°C (e.g., oyster farming requires 10-25°C maintenance)
- Marine Aquarium Cooling: ±0.5°C (recommended 24-26°C range)
Corrosion-Resistant Design
- Evaporator Material: Pure titanium or stainless steel (e.g., Sensen UA-2.8DR model)
- Secondary Coolant: Seawater or brine (calcium chloride solution, suitable for -40°C to 5°C)
Energy Efficiency Standards
Complies with GB/T18430.1 and other national standards; certain models achieve a COP (Coefficient of Performance) exceeding 3.5
Operating Principle
Heat Pump Technology
Utilizes a four-component cycle (compressor, condenser, expansion valve, evaporator) to transfer heat via seawater temperature differentials. 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 models handle -30°C brine for seafood rapid freezing.
Aquarium Cooling Process
Circulation pump feeds seawater into chiller tank → Compressor cools → Returned to main tank after cooling. Recommended temperature differential: 2°C (e.g., start at 28°C, stop at 26°C) to minimize energy consumption.
Model Comparison
| Type | Application | Features | Reference Model |
|---|---|---|---|
| Seawater Heat Pump Air Conditioner | Building cooling/heating | Energy-efficient, high COP | Haier HCQ-185G |
| Industrial Chiller | Aquaculture/processing | Corrosion-resistant titanium tubing, -30°C low-temperature | Ferguson marine flake ice machine |
| Commercial Chiller | Seafood Holding/Retail | 1-5 HP, intelligent temperature control | Sensen UA-2.8DR |
Technical Extensions
Reverse Flushing Function
Some industrial units support seawater reverse flow for heat exchanger cleaning (e.g., 'Yukun' vessel system)
Environmentally Friendly Refrigerants
R404A/R507 replace traditional R22, reducing ozone layer depletion
