Absorption chillers provide an economic and environmental alternative to conventional refrigeration. Combining high efficiency, low emission power generation equipment with absorption chillers allows for maximum total fuel efficiency, elimination of HCFC/CFC refrigerants and reduced overall air emissions.

Combining a cogeneration plant with an absorption refrigeration system allows utilization of seasonal excess heat for cooling. The hot water from the cooling circuit of the cogeneration plant serves as drive energy for the absorption chiller. The hot exhaust gas from the gas engine can also be used as an energy source for steam generation, which can then be utilized as an energy source for a highly efficient, double-effect steam chiller.

Up to 80% of the thermal output of the cogeneration plant is thereby converted to chilled water. In this way, the year-round capacity utilization and the overall efficiency of the cogeneration plant can be increased significantly.

This diagram illustrates the simplified operation of a typical tri-generation power plant for refrigeration, electricity, and hot water. This technology utilizes waste heat through a peak load boiler to absorption and compression refrigeration equipment, while generating electricity for on-site consumption.

In addition to Absorption Chillers, 2G offers a wide variety of other options to utilize thermal energy.

• Pressurized Hot Water
• Steam Generation Modules
• Thermal Oil Applications
• Hot Air Generation.
• ORC (Organic Rankine Cycle) Power Generation
