The Top 5 Things to Keep in Mind When Buying a Server Rack

It is important to keep in mind that rack air conditioners are intended for use in industrial and large spaces, they generate condensation and noise, and they exhaust hot air into the room where the enclosure is located. In a large room, the heat will dissipate. In a smaller room or confined space like a closet, the exhausted hot air from the AC unit can cause the room to overheat. If an AC unit is used in a small room, measures must be implemented to exhaust the hot air from the room. Air conditioner models differ in the amount of cooling output they can provide, so select one appropriate to your needs. Below are formulas to help calculate heat load and select a rack air conditioner: 1. Add up the wattage of each device and convert it to BTU (a device’s manual usually lists its wattage). You can also determine wattage with the following formula (Watts=Volts X Amps).(5) Remember that 1,000 Watts=1kW. 2. If a rack air conditioner will be used, for every 1 kW consumed, consider that 3412.14 BTU is generated. Air conditioners are rated for different BTU levels. Additional Tips Other ways to improve cooling include using blanking panels to manage air flow efficiency, selecting a rack with built-in channels for better cable management and improved air flow, and removing any obsolete or unnecessary equipment from the rack. In addition, consider that 3-phase power can significantly increase available amperage into the server rack, reducing the overall number of PDUs needed to power equipment and leaving more space for airflow.
