Highly efficient water heating system.

Author(s) : PEARSON S. F.

Summary

The paper describes an application of a packaged, transcritical carbon dioxide water chilling system. The system is arranged to extract heat from the return water of an existing chilled water system. The transcritical system assists the refrigerating effect of the existing system with the result that, when the transcritical system is used to produce hot water, the power consumed can be discounted against power required for the chilled water system. The package described is capable of providing about 50 kW of heating effect when heating water to 80°C. The paper describes the challenges presented in designing such a system and explains how they were overcome. The paper shows that provided there is an existing need for chilled water, high temperature hot water can be provided for minimal input of extra power.
