Background for the Olympic Ice plant <br /> In 1996, a used ice plant was purchased to refrigerate the Olympic Rink. The ice plant was built in 1983 and when <br /> purchased had about 15,000 operating hours. The ice plant was built in was purchased from RinkSystems for <br /> $66,200. The plant came from an arena from Stone Mountain, Georgia. <br /> Following is a list of significant repairs: <br /> ■ 2001 —Oil reclaim not working properly, rewired solenoids and relays. <br /> ■ 2002—Ice plant experienced excessive vibration when the compressor#1 ran causing short cycles of fill <br /> and dump times in the pumpers that pump the refrigeration out to the floor. Anti-vibration brads where <br /> installed on the discharge side of compressor#1. <br /> o 3/4" Elbow cracked on pumper vent leaking 4,470 pounds of refrigeration. <br /> ■ 2003 —Repaired leaks to oil receiver. <br /> o Repaired leaks to the snow melt pit <br /> ■ 2004—Replaced Evaporator tower and install back pressure regulator for the heat reclaim <br /> o Replaced leaky flange to the float trap <br /> ■ 2005 —Replaced heat reclaimer and repaired refrigeration leaks. <br /> o Replaced compressor# 1 motor <br /> ■ 2006 —Installed new loaders for compressors <br /> ■ 2007 —Sub Soil heating system;replaced solenoid, new temp control. <br /> ■ 2008 —Installed soft start system for the evaporator tower. Soft starts ramps up a motor in stages. <br /> ■ 2009 —Replaced carbon ring in compressor # 2 <br /> o Rebuild Compressor# 2 motor <br /> ■ 2011 —Replace motor for compressor# 1 <br /> ■ 2012—Replaced valve for heat recovery <br /> ■ 2013 —Replaced traps, fittings, and gaskets for heat recovery. <br /> ■ 2015 —Shut down the Ice plant to check for R22 leaks to the evaporator tower,vessel, and rink floor <br /> • Repair leaks in floor <br /> • Replace and repair valves, solenoids, gaskets, and packing's in vessel. <br /> • Level sand to rink floor. <br /> • Flush out old glycol in sub floor heating system and replace the glycol <br /> Refrigeration Replacement in Olympic Rink <br /> (In pounds) <br /> 2001 = 690 <br /> 2002 = 4,680 <br /> 2003 = 300 <br /> 2004 = 2,890 <br /> 2011 = 700 <br /> 2013 = 750 <br /> 2014 = 500 <br /> 2015 = 1,000 <br /> 2015 = 2,000 —To be installed the week of June 15 <br />
