Trinity College Dublin (TCD) is recognised internationally as Ireland\u2019s premier university and is ranked 14th position in the top 200 European universities by the QS World University Rankings.<\/p>\n
TCD campus, located in Dublin City Centre, occupies some 51 acres (including the Trinity Technology and Enterprise Campus).<\/p>\n

In 2019, Sirus was engaged to install energy-efficient cooling on the TCD Campus, first at the Lloyd building followed closely by the CRANN building.<\/p>\n
Lloyd Building<\/em><\/strong><\/p>\n The Lloyd is a 5 storey building with 2 basement levels. The first basement level contains MRI rooms which require critical services cooling.<\/p>\n Sirus installed a new high-efficiency 400 kW Air-cooled QUANTUM Turbocor Chiller<\/strong><\/a> from ENGIE Refrigeration to replace an end of life chiller which had been serving the building for the last 15+ years.<\/p>\n A redesign of the chilled water system allowed for the incorporation of a 90 kW Mitsubishi E Series High-efficiency Chiller<\/strong><\/a>, one of the first in Ireland at the time. This chiller serves as a dedicated redundancy for MRI systems that are used in the building.<\/p>\n Sirus also carried out BMS modifications to allow for this duty standby arrangement.<\/p>\n CRANN Building<\/em><\/strong><\/p>\n The CRANN (Centre for Research on Adaptive Nanostructures and Nanodevices) is one of the largest research institutes in Trinity College Dublin and Ireland’s leading nanoscience institute.<\/p>\n On the roof of the CRANN building, Sirus installed one 600kW<\/strong> and one 400kW<\/strong> Engie Air-cooled QUANTUM Chiller<\/a><\/strong>\u00a0to replace a 1.1MW twin screw chiller. Both chillers were installed to work in tandem to maintain building load.<\/p>\n These new chillers from ENGIE Refrigeration come with Thermosiphon Free Cooling. This means they can potentially deliver 40% of their nominal capacity without compressor operation, using the natural convection of refrigerant.<\/p>\n The installation of these chillers involved:<\/p>\n [\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,2_3″ _builder_version=”3.25″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” global_colors_info=”{}”][et_pb_column type=”1_3″ _builder_version=”3.25″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][\/et_pb_column][et_pb_column type=”2_3″ _builder_version=”3.25″ custom_padding=”|||” global_colors_info=”{}” custom_padding__hover=”|||”][et_pb_text disabled_on=”off|off|off” admin_label=”Title” _builder_version=”3.27.4″ text_font_size=”16px” text_line_height=”1.8em” header_2_font=”|600|||||||” header_2_font_size=”30px” 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=”{}”]<\/p>\n [\/et_pb_text][et_pb_divider _builder_version=”3.3.1″ module_alignment=”left” animation_style=”slide” animation_intensity_slide=”20%” animation_starting_opacity=”100%” locked=”off” global_colors_info=”{}”][\/et_pb_divider][et_pb_text _builder_version=”4.1″ text_font_size=”16px” text_line_height=”1.8em” max_width=”90%” custom_margin=”|||” animation_style=”flip” animation_direction=”left” animation_intensity_flip=”30%” animation_starting_opacity=”100%” global_colors_info=”{}”]<\/p>\n The load of the CRANN building is now being maintained by the 600kW chiller running at around 30% capacity for most of the time. The client has already noticed huge savings on energy bills and a significant improvement in the quality of the electrical supply to the building.\u00a0<\/p>\n Some of the lab equipment on site is very sensitive to spikes and slumps in voltage. Historically, whenever the large screw compressors on the twin screw chiller started, there was a noticeable slump, which influenced on the reading generated in the labs. Since the energy-efficient Chillers were installed, there hasn\u2019t been a single noticeable instance of the power slumping.<\/p>\n
