- Description
- Work shall consist of but is not limited to the following: Task 1: Replace and reroute a portion of the existing copper refrigerant line sets on two existing 30 Ton Liebert Computer Room Air Conditioning (CRAC) Units. �Each Liebert Unit has two R-22 refrigerant circuits each having approximately 120 pounds of refrigerant.� Due to operational requirements of the server farm, only one circuit of one Liebert Unit can be down at a time.� R-22 Freon can be recycled for #1 and #3 CRAC units if the acid content is acceptable, otherwise new Freon shall be used. CRAC-2 will be completely replaced with a new unit.� Completely replace the refrigerant lines for the new CRAC-2 and charge the system. Each of the 6 existing line sets is comprised of one 1 inch line and one 1� inch line (see drawings for new and existing routing).� Replacement lines will use ACR copper piping and will be insulated with Rubatex insulation.� Provide insulation blocks at pipe supports and aluminum jacket around exterior piping to protect insulation.� There will be combination isolation/shraeder valves installed at the condenser end of the new portion of the line sets as well as isolation/shraeder valves installed on the linesets just outside the indoor unit (Evaporator) approximately 4 feet above the finished floor.� The result will be two isolation/shraeder valves on each line. Include installation of replaceable filter dryer assemblies. Linesets will exit the building through the concrete precast wall at approximately 12 feet high.� Lines will be supported by pipe stands or hangers keeping at least a 12 foot clearance above the ground until they reach the condensing units. Note:� The contractor will ensure cooling to the server farm is maintainted during the performance of this work by only having one circuit of each CRAC unit down at a time. Air conditioning must be sufficient to keep the server farm continuously at 73 degrees +/- 2 degrees. Task 2: Replace CRAC-2 in its intirety.� The new unit will consist of an interior 30 Ton Precision Cooling System CRAC Unit with a new 30 Ton DX Air-Cooled Microchannel Condensing Unit.� The new units will be installed in the same locations as the old interior/exterior systems.� Due to the criticality of the server farm, it is critical the demolition of the existing CRAC only occur immediately prior to the installation of the new unit.� Install combination isolation/shraeder valves at the condenser end of the line sets as well as just outside the indoor unit (Evaporator) approximately 4 feet above the finished floor.�
