US Energy Group has launched USE Controller - AC, providing precise monitoring and ultimate control of steam-driven chiller functions. Utilizing the functionality of US Energy Group's Building Energy Management System (BEMS) and drawing upon both indoor and outdoor temperatures, the USE Controller - AC controls the central chiller plant increasing efficiency and reducing the fuel needed to provide air conditioning throughout the building. The system provides immediate savings with payback in less than two years. "For years, we have helped owners and managers save money by heating their buildings more efficiently," said Jerry Pindus, CEO of US Energy. "Now, we can help them save substantially on their air conditioning costs as well. When owners and managers think of fuel costs, they always think of heating season, but actually cooling a building uses twice the amount of fuel." The USE Controller - AC cools the building more efficiently by lowering the building temperature to match a designated set-point (based on algorithms integrating indoor temperature readings and return water temperatures) and maintaining the building at that temperature. While many antiquated air conditioning systems automatically stay on based on a timing device or water circulating temperature, the USE Controller - AC cools the building only when needed and stays off when the temperature inside the building is already cool. The building stays at a comfortable and steady temperature and less fuel is used. "USE Controller - AC harnesses advanced technology and fully integrates with the USE Manager online building management system," said David Unger, COO of US Energy Group. "It provides all of the monitoring and enhanced control as our heating controls, including specialized alerts for chilled water temperature." Central to USE Controller - AC is a network of proprietary algorithms that integrate information from indoor and outdoor sensors, sending a parameter change feedback to the chiller about cooling load. The reaction uses steam, which evaporates lithium bromide and cools the water which acts as a refrigerant, circulating throughout the building and maintaining the designated temperature. Because the system shuts off or generates less cooling when the building is already cool, less steam is used, which means lower fuel costs. USE Controller - AC is an option available in buildings with a central chiller plant. To use USE Controller - AC, US Energy Group's BEMS is switched from heating mode to cooling mode.
