Winter farming helper! Take the cost of heating 1 ton of water 1 time (15℃-45℃) as an example, the heating efficiency of the equipment reaches 450%, and the cost of raw materials is only 4.65 yuan, which is 60% more energy-efficient than traditional boilers.

In recent years, Zhejiang, Jiangsu, Shandong, and other places have taken the lead in phasing out coal-fired boilers for heating in aquaculture, promoting a revolutionary development in the application of thermal energy in the national aquaculture industry. Since 2019, several national ministries and commissions have successively released documents on the control of water pollutants in local aquaculture, ecological environment supervision of seawater aquaculture, etc., and various regions have begun to introduce plans to implement measures such as sewage discharge control and geothermal utilization.

Green environmental protection has become a major trend in the development of the aquaculture industry. Clean energy, renewable energy, and cogeneration units have begun to replace traditional heat energy supply. In particular, by 2030, China will achieve "carbon peak," and the entire industry will face pressure to "reduce carbon." Traditional farming facilities that are inefficient and wasteful are accelerating their upgrading and replacement, and heating technologies that do not meet development needs are facing elimination. Enterprises and farmers with a long-term vision are turning their equipment needs to more efficient and environmentally friendly "black technology."

As a national "specialized, sophisticated, distinctive, and new" high-tech enterprise, Shandong Naxin New Energy Co., Ltd.'s seawater source heat pump unit developed by the company is 60% more energy-efficient than traditional boilers, and the heat production power can achieve "1 kWh of electricity for 4 times the heat." With high-tech breakthroughs in traditional heating methods, it significantly alleviates the energy shortage in the aquaculture industry. This technology is expected to become a revolutionary breakthrough in environmentally friendly aquaculture production.

Breakthrough in Revolutionary New Technology

Seawater source heat pump units are devices for cooling and heating systems that use seawater as a heat source, collecting the large amount of low-grade thermal energy present in shallow water sources on the earth's surface. This technology uses the principle of heat pumps, which transfers low-grade thermal energy to high-grade thermal energy with a small input of high-level electricity.

In China's coastal aquaculture industry, such as shrimp breeding, industrial shrimp farming, and high-end marine fish farming, maintaining a constant water temperature in the tanks is crucial. With the increasing pressure on space for aquaculture, industrial farming has shown more promising market potential. Effective constant temperature technology can break through production cycles and overcome traditional climatic constraints in aquaculture, thereby significantly improving pond productivity.

Under the guidance of national policies and market demand, efficient, green, and environmentally friendly heating technology is becoming more widely used in the aquaculture industry. In fact, China has a coastline of 32,000 kilometers, including a mainland coastline of 18,000 kilometers and an island coastline of 14,000 kilometers, with an inexhaustible supply of seawater resources. Therefore, seawater source heat pump units can be widely applied in coastal areas.

At the same time, the widespread application of seawater source heat pump technology has positive implications for alleviating energy shortages, improving energy efficiency, promoting energy conservation, and environmental protection. The potential for this technology in the market is immense.

1 Unit of Electricity Produces 4 Times the Heat, Saving 60% of Energy

In practical applications, heat pump units do not directly heat the water for aquaculture. Instead, the water that has been heated by the heat pump unit is circulated through auxiliary equipment installed in the tank, and the principle of heat transfer is used to gradually warm up the aquaculture water. Heat pump units provide heat and cooling capacity, which can effectively heat and cool seawater, achieving low energy consumption and pollution-free heating and cooling effects without using groundwater.

This approach is in line with China's basic policies on energy conservation and environmental protection, as well as strategic requirements for sustainable economic development. For example, heating 1 ton of water once (from 15°C to 45°C) requires only 4.65 yuan in raw materials, with a heating efficiency of up to 450%, saving 60% more energy than traditional boilers.

Replacing coal-fired boilers with Na Xin sea water source heat pump units for heating small shrimp breeding sheds can save over 60% in electricity consumption. Each shrimp shed heating cycle can save energy costs of CNY 4009, with savings of CNY 80,000 for 20 shrimp sheds, CNY 160,000 for 40 shrimp sheds, and CNY 200,000 for 50 shrimp sheds.

Calculating the cost savings over several years shows significant cost savings and greatly reduces operating costs while improving system efficiency.
