The design and <br /> construction included a water- cooled chiller and a cooling tower to create and maintain the ice . <br /> The current chiller system utilizes ammonia , which is often found in older chillers used for ice <br /> E <br /> rinks . However , this presents health and safety risks if ammonia is released due to equipment <br /> failure or maintenance mistakes . Furthermore , both the existing cooling tower and chiller system <br /> have exceeded their useful life , and ammonia is no longer supplied by major chiller manufacturers . <br /> The ice rink cannot function without the chiller continuously operating to maintain the ice , as the <br /> chiller pumps cold brine beneath the ice rink floor to create and preserve the ice . <br /> The recommended solution is to replace the ammonia chiller with an air- cooled chiller that can <br /> produce sufficiently cold water for ice - making . This single unit will replace both the cooling tower <br /> and the water- cooled chiller . The construction of this project is expected to take approximately <br /> four (4 ) weeks . During this time , the ice rink will be non - operational for a total of two (2 ) weeks , or <br /> no more than fourteen ( 14 ) days . The work involves adding a new concrete pad for the air- cooled <br /> chiller , installing new piping and connections inside the chiller room , and setting up pumps and <br /> electrical systems while the existing water- cooled chiller remains operational . After completing all <br />
