Feasibility of using an integrated small-scale CHP unit plus desiccant wheel in a leisure complex

By employing a natural-gas-fired combined heat-and-power (CHP) system in a leisure complex, the waste heat from the CHP units can be used to regenerate a desiccant wheel. The latter is employed to provide dehumidification for the indoor swimming pools in a leisure complex. A payback period of ~4 years has been predicted for this system, assuming zero amortised value for the CHP units that had to be replaced. Any resaleable value for the removed units would lead to an even shorter payback period.
