Heat pump

A heat pump in aquaculture is a thermal system used to regulate water temperature in fish farming tanks or aquaculture systems. It works by transferring heat from a source (air, water, or ground) to the aquaculture water, allowing it to heat or cool the water depending on the needs of the species.

How It Works

The heat pump operates through a thermodynamic cycle:

• It captures heat (calories) from the environment (air, ground, or water).

• This heat is compressed and transferred to a heat exchanger.

• The exchanger then warms (or cools) the water in the system.

• The system can reverse the cycle to cool the water, if needed (reversible heat pump).

Benefits in Aquaculture

• Precise temperature control, essential for fish health and growth.

• Energy savings: much more efficient than traditional heating systems.

• Reduces temperature fluctuations, minimizing stress for sensitive species.

• Usable year-round, regardless of outdoor climate.

• Eco-friendly, with lower energy consumption and high performance.

Common Applications

• Tropical aquaculture: to maintain warm water temperatures (tilapia, shrimp, etc.).

• Cold-water aquaculture: to prevent excessive cooling in winter.

• Hatcheries and RAS (Recirculating Aquaculture Systems): tight temperature control for juvenile stages.

• Aquariums and research facilities: precise thermal regulation for breeding and scientific studies.
