![]() The new method is based on the 29 largest cities worldwide and with data-center-specific indoor temperature conditions. It is based on the average temperatures of the USA’s 29 major cities. The IPLV is an index focused on partial thermal loads and outdoor temperature data variation for air intake in the condenser. A new method, COP WEUED (COP–world energy usage effectiveness design), is proposed based on the IPLV (integrated part load value) methodology. This method benefits fixed-speed compressor equipment with a constant inlet temperature air-cooled condenser (35 ☌). The energy efficiency of these pieces of equipment is compared according to the Energy Standard ASHRAE 90.1-2019, using the index Net Sensible Coefficient Of Performance (NetSCOP). The air conditioning equipment is responsible for approximately 38% of the energy consumption of data centers. As the world data traffic increasingly grows, the need for computer room air conditioning (CRAC)-type equipment grows proportionally.
