    Take Some of the Guesswork out of Data Center Efficiency

    Subzero understands how complicated it can be when trying to figure out how to save energy and money in your data center and we are here to help make it easier. Our Senior CFD Manager, Gordon Johnson, has created an easy-to-use calculator suite that can help you figure out some of those complicated scenarios and point you in the right direction.

    The Subzero Calculator Suite consists of 6 calculators and can be downloaded in both US units and SI units.

    1. ROI Calculator
    Calculate the annual cost of operating your data center and estimate the yearly savings after installing containment and increasing the supply temperature from the CRACs. You can also estimate new PUE after containment and the ROI payback of a containment project based on the total cost.

    2. VFD Calculator
    Lowering the fan speeds on CRACs, especially after installing containment, saves energy and money. This calculator allows you to enter before and after fan speed, CRAC CFM, and fan motor power, and via the Fan Affinity Law provides the new fan motor power and the annual $ savings based on the new fan speed.

    3. CRAC Annual Cost Calculator
    Determine the total annual cost of running a CRAC unit by entering a few details.

    4. CRAC Cooling Calculator
    Determine the true kW of cooling from any CRAC or cooling unit based on airflow (CFM) and the Delta T (return air temperature – supply air temperature) across the CRAC.

    5. Airflow CFM Calculator
    Determine airflow in CFM needed to cool a rack based on the rack’s kW and the Delta T (temperature rise of air through the servers). Determine if you meet your design cooling capacity of supply airflow from the CRACs versus demand airflow from the IT equipment.

    6. UPS kW Calculator
    Determine the UPS Heat Load (kW) based on user inputs of UPS power rating, UPS % load, and UPS % efficiency.
