recordOCP_1kW_OAM_Water
OpenCompute example for 1 kW OAM with DI water as working fluid
Extends from Buildings.Fluid.DataCenterEquipment.Racks.LiquidCooledSinglePhase.Data.Generic (Generic data record for liquid-cooled single-phase rack).
Information
This specification is for a 1 kW Open Accelerator Module (OAM) based on the Open Compute Project (OCP) report by Cheng et al. (2023). The data is based on Figure 8, which is for a single cold plate with deionized (DI) water as the working fluid.
Note: The values for dp_nominal, n and deltaM are generic,
as no data for these parameters were found.
