Karlis Aluminium Door&Window Factory Hot Water Absorption Chiller

Project Overview:

Customer: EXALUS Aluminium
Location: Poland
Equipment Selection:

• 1 unit of hot water absorption chiller
• 1 MW internal combustion engine from MWM

Main Feature:

• The hot water absorption chiller is powered by waste heat from the exhaust and jacket water of a 1 MW internal combustion engine (ICE), supplied by MWM.
• The system is integrated with a Combined Heat and Power (CHP) setup that provides both cooling and electricity.

Project Details:

• EXALUS Aluminium is one of the largest manufacturers of aluminium products, primarily serving Poland and surrounding countries. To improve energy efficiency, the company has adopted a hot water absorption chiller that works in tandem with a 1 MW internal combustion engine (ICE).
• The ICE generates electricity while its exhaust and jacket water are used to provide the necessary thermal energy to power the absorption chiller. This allows the company to utilize waste heat that would otherwise be lost in the power generation process.

Cooling Usage:

• The cooling produced by the system is split evenly between the office air conditioning and the production process, with 50% used for each.
• The system operates year-round, providing a reliable source of cooling and helping to reduce energy consumption and costs.
• Additionally, the electricity generated by the internal combustion engine is connected to the grid, allowing EXALUS Aluminium to supply excess power and potentially earn from feed-in tariffs or reduce their own electricity costs.

Key Benefits of the Solution:

• Energy Efficiency: The use of waste heat from the internal combustion engine ensures that energy is used efficiently, lowering both operational costs and the environmental footprint.
• Cost Reduction: By generating electricity on-site and using waste heat for cooling, EXALUS Aluminium reduces its dependency on external power sources and minimizes cooling costs.
• Sustainability: The integrated CHP system reduces emissions by maximizing the utility of the generated heat and electricity, making it an environmentally friendly solution.

This project highlights the integration of CHP technology and absorption chillers as an effective solution for industrial applications, providing cooling and power generation with minimal additional energy input.
