The chilled water plant at St. James\u2019s Hospital in Dublin required replacement due to high energy consumption and the fact that the chillers were end-of-life. Reliability of critical utility and energy efficiency were the highest priorities on this project so Sirus was engaged to install the new cooling solution at the hospital.<\/p>[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_4,3_4″ _builder_version=”4.21.0″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}”][et_pb_column type=”1_4″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][\/et_pb_column][et_pb_column type=”3_4″ _builder_version=”4.16″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text disabled_on=”off|off|off” admin_label=”Title” _builder_version=”4.16″ text_font_size=”16px” text_line_height=”1.8em” header_2_font=”|600|||||||” header_2_line_height=”1.5em” custom_margin=”||5px|” animation_style=”slide” animation_direction=”top” animation_intensity_slide=”20%” animation_starting_opacity=”100%” global_colors_info=”{}”]

Sirus installed 2 no. 750 kW QUANTUM Air-cooled Turbocor Chillers<\/a> to replace the two chillers which had been serving the hospital for the last 15+ years.<\/p>\n The chillers are located on the roof and surrounded by buildings so a 500-tonne crane was required for the project. The chillers were replaced one at a time allowing for a seamless transition while maintaining continuous critical cooling to the hospital.<\/p>\n The two 750kW QUANTUM Air-cooled Chillers<\/a> give an installed capacity of 1.5MW. Both chillers were configured to work in tandem or separately in order to maintain the building load.<\/p>\n The installation of these chillers involved:<\/p>\n \n <\/p>[\/et_pb_divider][et_pb_text _builder_version=”4.21.0″ text_font_size=”16px” text_line_height=”1.8em” custom_margin=”|||” animation_style=”flip” animation_direction=”left” animation_intensity_flip=”30%” animation_starting_opacity=”100%” hover_enabled=”0″ global_colors_info=”{}” sticky_enabled=”0″] In the first contract year (Dec 2021 – Dec 2022), the chillers achieved an average EER of 8.<\/strong>\u00a0They yielded a total energy saving of 884,828 kWh<\/strong> which equates to 386 tonnes of CO2<\/sub> saved<\/strong> in the first year of operation.<\/p>\n The contact-free magnetic-bearing Turbocor\u00ae<\/sup> compressors allow for very low turndown ratios (<15%) achieving ESEER >9<\/strong> during part-load operation.<\/p>\n The exemption of oil not only increases operation life but also maintains higher efficiencies and reduces environmental impact. The chillers operate extremely quietly with no vibrations.<\/p>\n The use of EC fans (with auto speed adjustment, PLC with control system optimisation including optimised fan control) means that all condenser fans modulate airflow, therefore further reducing energy consumption.<\/p>\n Remote access allows for monitoring and further optimisation where necessary.<\/p>[\/et_pb_text][et_pb_divider show_divider=”off” _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_divider][et_pb_text disabled_on=”off|off|off” admin_label=”Title” _builder_version=”4.16″ text_font_size=”16px” text_line_height=”1.8em” header_2_font=”|600|||||||” header_2_line_height=”1.5em” custom_margin=”||5px|” animation_style=”slide” animation_direction=”top” animation_intensity_slide=”20%” animation_starting_opacity=”100%” global_colors_info=”{}”] \n <\/p>[\/et_pb_divider][et_pb_text _builder_version=”4.21.0″ text_font_size=”16px” text_line_height=”1.8em” custom_margin=”|||” animation_style=”flip” animation_direction=”left” animation_intensity_flip=”30%” animation_starting_opacity=”100%” global_colors_info=”{}”] St James\u2019s Hospital has signed an Energy Performance Contract (EPC)<\/a> with Veolia<\/a> in partnership with the Carbon and Energy Fund Ireland (CEFI)<\/a>.<\/p>\n Under the EPC agreement, Veolia installs and operates energy-efficient equipment in the hospital.
