I'm simulating a DataCenter equipped with CRACs. These devices have a very high rated air volume flow rate. For the equipment I'm using the ratio is 0.00006822 m³/s per W (0.2456 m³/h per W or 865 m³/h per TR).
The problem is that the Coil equipment: Cooling: DX: Single: Speed accepts a maximum 0.00006041 m³/s per W and when I put a higher flow relation to this, the error of EnergyPlus reporting me that the flow ratio by load is higher than the maximum acceptable.
* Severe * Sizing: Coil:Cooling:DX:SingleSpeed "CRAC - DATA CENTER": Rated air volume flow rate per watt of rated total cooling capacity is out of range. * ~~~ * Min Rated Vol Flow Per Watt=[4.027E-005], Rated Vol Flow Per Watt=[6.821E-005], Max Rated Vol Flow Per Watt=[6.041E-005]. See Input Output Reference Manual for valid range.
Is there any other component in the EnergyPlus that properly represents a CRAC and supports a greater rated air volume flow rate ratio.
