Micro-cogeneration Waste-heat-input type Natural Chiller

Overview

The use of exhaust heat with the absorption chiller-heater “Genelink,” which was previously managed with 100 kW to 300 kW class CGS, can now be handled with multiple 25 kW units of the micro-cogeneration system “Genelight.”
In the past, the exhaust heat from micro-cogeneration systems was primarily limited to water heating applications due to the low temperature of the recovered hot water (65°C to 75°C). Therefore, there has been a demand to expand its applications. To address this, we have increased the power generation efficiency of the 25 kW Genelight to 33.5% and raised the temperature of the recovered hot water to 85°C. This has allowed us, for the first time, to successfully utilize exhaust heat from a micro-cogeneration system for cooling purposes.

*What is “Genelink”?
“Genelink” is a system that reduces the amount of fuel gas consumed by the high-temperature generator in traditional gas absorption chiller-heaters. It achieves this by installing a waste heat recovery heat exchanger between the absorber and the regenerator in the absorption liquid line, and heating the absorption liquid using waste heat (hot water) from the gas engine.
