![]() The heat the chillers pull out of that loop is transferred or recovered to provide 150⁰ water on the condenser side of the DHRC machine. These DHRC chillers (right) provide approximately 100 tons of cooling to the chilled water loop. Rather than waste the heat that the hospital already paid to collect at the main chiller plant, the design team decided to implement Multistack Dedicated Heat Recovery (DHRC) chillers. Simultaneously, the boilers in the building would burn natural gas to produce heat for the building heating loads. In a traditional system, the chillers would pull heat out of the building chilled water loop and reject that heat out at the cooling tower. At the same time, the mechanical system has VAV boxes and reheat coils for humidity control requiring year-round heating. There are MRI machines, computer rooms, and other imaging equipment requiring year-round cooling. This would be very typical of many hospital facilities. Elizabeth Hospital indicated that they have a need for simultaneous heating and cooling for most of the year. After that, the hospital can expect to have 20-25 years of $25,000 to $30,000 savings per year.ĭuring the design phase, St. When the WME700 machines were compared to traditional oil centrifugal machines, the payback was under 5 years for the frictionless compressor technology. Focus on Energy contributed over $63,000 in rebates to the owner due to the selection of these premium efficiency machines. The design also reduces yearly maintenance costs in terms of oil samples, oil pumps, oil filters, etc. The compressors "levitate" on oil-less bearings and do not require any oil in the refrigerant which provides excellent efficiency with zero friction losses. The chillers utilize oil-less magnetic bearing compressor technology which offers premium full load and part load efficiencies that are sustainable over the life of the chiller. The upgrade to the centrifugal chiller plant included the installation of two Daikin WME700 chillers (above right) with sustained efficiencies that are unmatched in today's market. ![]() Tweet Garot and August Winter & Sons, Inc served as the local installing mechanical contractors and Masters Building Solutions provided consulting services and equipment to reach the hospital's goals. ![]() located in Madison, WI became involved as the lead mechanical engineer. There was also a strong desire to improve chiller plant efficiency and reduce operating costs as part of the chiller plant overhaul. As part of the improvements and additional square footage add, the hospital needed to increase the capacity of the central chiller plant. The largest part of the renovation included a 5-story patient bed tower on the Northeast side of the hospital campus. In 2012, the hospital announced a plan for significant upgrades with capital investment in excess of $100M. Approximately 375 licensed patient beds and 350 medical staff serve the local community. The hospital was founded in in 1899 by the Daughters of the Sacred Hearts of Jesus and Mary, a part of the Franciscan Sisters order. Elizabeth Hospital, located in Appleton, WI is a comprehensive health care facility offering primary and specialty care services to residents of Northeast Wisconsin.
