Computer Room Air Conditioners

Sign up for e-mail updates on regulations for this and other products

As defined in the Code of Federal Regulations (CFR), “computer room air conditioners” means all units manufactured by one manufacturer within a single equipment class, having the same primary energy source (e.g., electric or gas), and which have the same or comparably performing compressor(s), heat exchangers, and air moving system(s) that have a common “nominal” cooling capacity. 10 CFR 431.92 Manufacturers have been required to comply with the U.S. Department of Energy (DOE) energy conservation standards for computer room air conditioners since 2012.

Recent and Ongoing Activities

DOE has published in the Federal Register notice publishing an analysis of the energy savings potential of amended industry consensus standards for certain classes of computer room air conditioners (CRACs) and air-cooled, three-phase, small commercial package air conditioning and heating equipment with a cooling capacity of less than 65,000 Btu/h (air-cooled, three-phase, small commercial package AC and HP (<65K) equipment). DOE is also soliciting information regarding energy conservation standards for CRACs and air-cooled, three-phase, small commercial package AC and HP (<65K) equipment for which the industry consensus standards have not been amended, pursuant to EPCA’s six-year-lookback review requirement. This notice of data availability (NODA) and request for information (RFI) solicits information from the public to help DOE determine whether more-stringent amended standards for CRACs or air-cooled, three-phase, small commercial package AC and HP (<65K) equipment would result in significant additional energy savings and whether such standards would be technologically feasible and economically justified.

DOE has published Federal Register notice of data availability (NODA) publishing an analysis of the energy savings potential of amended industry consensus standards for certain classes of computer room air conditioners (CRACs) and new industry standards for dedicated outdoor air systems (DOASes). DOE is also initiating a data collection process through a request for information (RFI) soliciting information to help DOE determine whether amended standards for classes of CRACs and new standards for DOASes would result in significant energy savings and whether such standards would be technologically feasible and economically justified.

Current Standard

Computer room air conditioners manufactured and distributed in commerce, as defined by 42 U.S.C. 6291(16), must meet the energy conservation standards specified in the Code of Federal Regulations at 10 CFR 431.97.


Current Test Procedure

To determine that computer room air conditioners that are currently manufactured or distributed into commerce are in compliance with DOE standards, manufacturers must follow the test procedure methods specified at 10 CFR 431.96.
