Seawater source centrifugal heat pump heating, to build a clean heating platform for medical universities

Global climate change poses a major threat to human society, and more and more countries have elevated "carbon neutrality" to national strategies, putting forward a vision of a carbon-free future. The proposal of China's "double carbon" goal has brought great changes to the refrigeration and air conditioning HVAC industry, and enterprises with waste heat recovery and efficient utilization technology and efficiency reduction and carbon reduction solutions will become the main force to achieve China's energy structure optimization and "double carbon" goals.

Ebara has been deeply cultivating the domestic and foreign waste heat utilization market for 25 years, developing more than 100 applications in waste heat recovery segments, keeping up with the pace of national energy conservation and environmental protection in the past two years, accurately anchoring the "carbon neutrality" goal, actively developing efficient waste heat utilization products, broadening the range of energy-saving products, expanding the scope of business services, providing the market with world-class cooling and heating system solutions, and striving to promote the realization of China's dual-carbon goals as scheduled.

As a fist product under the goal of "double carbon", the RTGC series of high-efficiency centrifugal cold water (Heat Pump) units has won market recognition and customer praise with many advantages such as full range of Level 1 energy efficiency, stable operation, low noise, and non-standard customization. The product application covers the industrial field that urgently needs to improve efficiency and reduce carbon, the building field that urgently needs energy saving and consumption reduction, and the urban clean heating and heating field.

Jinzhou Medical University is one of the many institutions of higher learning served by Ebara, with a total area of 851,300 square meters and a total construction area of 388,300 square meters, including office buildings, libraries, teaching buildings and student apartments. Two high-efficiency Centrifugal Heat Pump units and one Screw Heat Pump unit jointly provide clean heating for the campus and provide a suitable learning space environment for teachers and students of the whole school.

The total production capacity of the project is 8550Kw, which saves 36080 tons of standard coal and reduces CO2 emissions by 94528 tons per year during winter operation. It is worth noting that the waste heat source of the three units of the project is seawater, which completely solves the problem of strong corrosiveness of seawater, recovers the waste heat of seawater through high-efficiency centrifugal heat pump units, provides heating warm water at 45 °C, and the screw heat pump unit is to deliver 60 °C warm water, which escorts teachers and students in the school to warm up through the winter!
