High COP absorption chiller driven by engine cooling water.

Author(s) : TAKADA S.

Summary

In cogeneration systems, absorption chillers play an important role for utilizing the heat exhausted from engine, especially during summer. A conventional one has a low COP of only about 0.65, and its COP falls abruptly as the engine cooling water temperature falls. The new type has a higher COP of 0.75, and can keep the COP in the wide range of the engine cooling water temperature (from 90 to 70 deg C). It is also 30-40% smaller. These improvements were achieved by the following: 1. minimizing the lithium bromide solution flow rate; 2. using the tubes outside surface of which can be perfectly wetted by only the minimized solution flow rate to keep the high heat transfer rate; 3. using the spray type generator instead of the conventional flooded type.
