Liquid Cooled Server RacksImmersion cooling consists of placing servers in a dielectric liquid to efficiently remove heat. In a traditional data center, waste heat from servers is rejected into the server room before being moved around and cooled. In immersion cooling, the heat is absorbed by a liquid at the point of heat generation. The liquid is significantly more effective at absorbing heat than air because of its higher density and heat capacity. As a result, the liquid can be maintained at higher temperatures than room air in a traditional data center, improving chiller performance and allowing for more free cooling opportunities.

The project team conducted a field evaluation of savings from a liquid-cooled server rack at a telecommunications customer site in the ComEd service territory. The study established baseline energy use, monitored data after the installation and analyzed the energy savings. To understand market barriers for implementation in the ComEd service territory, the team also interviewed manufacturers and potential customers.

Residential Dryer Moisture SensorThis project was a savings evaluation of a product that converts a standard clothes dryer into a smart dryer, informing users when clothes are dry. When using a residential clothes dryer, many customers waste energy by running the dryer on a timer setting, drying clothing for longer than necessary. This device is a retrofit technology to turn an electric residential dryer into a smart dryer. A temperature and humidity sensor is attached to the dryer drum via a permanent magnet to monitor when the clothes are dry. Users can take action to shut off the dryer upon the notification to their smartphone or manually at the machine to save energy. There is potential to pair the monitoring device with a smart plug to shut off the dryer on its own after the smartphone application notifies the smart plug.
