Joy Cone Adsorption Chiller Design

RETTEW completed a cooling system upgrade analysis and conceptual design engineering for Joy Cone Company where we identified significant savings opportunities for the system design they needed. The design was to upgrade the cooling system that currently serves several process areas at their Hermitage, Pennsylvania, facility.

Using data generated during our previous investigation, we obtained vendor quotes for equipment that would ultimately yield a higher-performing, capital- and cost-saving system upgrade. Our design recommendations included replacing both existing chillers with similarly-sized adsorption chillers, replacing multiple air handling units and fan coils with two centralized units, and installing new ductwork to interconnect the new make-up air units to existing outlets in the process areas. Our design also converted the existing heat recovery units and exchangers on the oven exhaust systems to a glycol-based liquid system to provide waste heat to the adsorption chillers. We also replaced existing chilled waterline insulation with higher-performing material throughout the cooling water, chilled water, and air systems. With this system design, RETTEW projects a savings of more than 700 kilowatts of energy demand, or $2 million over a ten-year span, in addition to the reduction of load caused by aging equipment.
