Cooling requirements Sample Clauses

Cooling requirements. It is expected that the components of the NBHS will require cooling (besides cryogenic pumps). General requirements and parameters of cooling options available at the premises of the buyer are given in the following table. The proposed design and the delivered devices must not require additional coolant types or lower coolant temperatures from the Buyer. The Seller can utilize waste products from the NBHS (e.g. cold nitrogen from cryopump radiation baffle cooling) or include other coolants in closed loops inside NBHS components and transfer heat via heat exchangers to the coolants available at the buyer’s premises. No. Name and description of the requirement Value / description 1) Allowed Coolant type Water, demineralized water, ambient air 2) Cooling water temperature The system must be equipped with cooling water temperature monitoring. Cooling water temperature cannot reach the boiling point of water at the operating pressure. 3) Air flush system For the case the cooling water circulation stops for longer than 5 min a gas flushing of the cooling pipes has to be performed automatically in order to prevent damage to the system by the freezing the cooling medium 4) Cooling of the device All subsystems and components accessible during operation by personnel must be cooled so that the surface temperature will not exceed 55 °C. 5) Cooling lines The devices must include all required coolant distribution pipes. 6) NBHS Coolant connections The buyer will provide one coolant supply and return line for each complete NBHS (Device No. 1 + at least one Device No. 2) 7) Air cooling The buyer will not supply coolant air other than the ambient air where equipment to be cooled will be located. No. Name and description Value / description 1) Lowest available coolant temperatures Demineralized water: ≥10°C Plain water: ≥10 °C Air: ≥ 25 °C 2) Maximum operational continuous coolant flows per 1MW of neutral beam (1 ion source) Does not include operation of full scale calorimeter Demineralized water: 30 l/min Plain water: 350 l/ min Air: 100 l/ min 3) Maximum input coolant pressures Demineralized water: ≤5 bar Plain water: ≤8 bar Air: ≤5 bar
