Seawater heat pump pilot project in Croatian shipyard – pv magazine International


Viktor Lenac Shipyard in Croatia goals to exchange electrical boilers and water-to-water warmth pumps with seawater warmth pumps, to offer warmth and funky buildings. The pilot mission is supported by EU funding and launched a young to help the development of the seawater warmth pump.

Viktor Lenac Shipyard (VLS), one of many largest shipyards in Croatia, is creating a pilot mission to put in a seawater warmth pump. The system covers a lot of the heating and cooling wants of the constructing complicated within the city of Martinscica.

The EU-funded Seawater Warmth Pump Undertaking goals to exchange the present water-to-water warmth pump and electrical boiler with a brand new warmth pump, which can use seawater as its heating supply. The present system has a required output of 280 kW, with 100 kW supplied by the water warmth pump.

“The present warmth pump takes thermal vitality from the method water that’s additional used within the stream system to keep up a minimal temperature of three C, nevertheless, because of the excessive price of the concession charge for within the strategy of water, the operation of the warmth. The pump doesn’t make a monetary revenue or sufficient vitality, which represents the issue that the mission goals to unravel,” explains VLS on the mission’s web site.

VLS mentioned that the brand new warmth pump’s fundamental benefit is the comparatively fixed temperature of the ocean water all year long.

“Because of the extra favorable temperature parameters of seawater in comparison with course of water, the heating issue of the seawater warmth pump is nice,” mentioned VLS.

VLS has lately launched a young to search out corporations that may supply preparatory companies to help the design and technical documentation required to fabricate the seawater warmth pump. The deadline for submissions is February 24, 2023. The contract has an estimated worth of €30 million ($32 million).

The set up of the seawater warmth pump is anticipated to cut back electrical energy consumption by 155,872 kWh/yr and CO2 emissions by 36,600 kg/yr. The mission has a complete deliberate price of €480 million and is supported by €233 million in grants from the Croatian Ministry of Regional Improvement and the European Union. The event began in June 2022 and the completion of the mission is anticipated by March 31, 2024.
