The system’s controls are automated, adjusting the glycol’s temperature based on real-time weather data, including air temperature, humidity, and sunlight exposure. For instance, on sunny days, sensors detect increased solar radiation and lower the glycol temperature to counteract melting. This dynamic approach ensures the ice remains stable, even when Chicago’s weather fluctuates dramatically.
One of the system’s standout features is its ability to operate efficiently in both winter and summer. During colder months, the refrigeration system works in tandem with natural freezing temperatures, reducing energy consumption. In warmer months, when the Ribbon is repurposed for walking and rollerblading, the system is temporarily shut down, but the infrastructure remains in place, ready for the next skating season. This dual functionality highlights the system’s adaptability and sustainability, making it a model for other outdoor ice attractions.
Maintenance of the refrigeration system is a year-round task, involving regular inspections, glycol fluid checks, and pipe integrity assessments. Technicians also monitor the ice surface for signs of wear, such as cracks or uneven thickness, and make adjustments as needed. For example, if a section of the Ribbon shows signs of melting, the glycol temperature in that area is lowered to restore ice quality. This proactive approach minimizes downtime and ensures the Ribbon is always ready for visitors.
For those curious about the practicalities, the system’s energy efficiency is achieved through the use of variable-speed pumps and insulated piping, which reduce heat loss and lower operational costs. Additionally, the glycol solution is non-toxic and environmentally friendly, aligning with the park’s sustainability goals.
