Which term refers to large cooling HVAC units that operate without ductwork and blow cool air from both ends of a data hall?

• A. Director of Construction (DOC)
• B. Data Center Services Procurement (DCSP)
• C. Electrical Contractor (EC)
• D. Data Air Handling Unit (DAHU)

Answer: (D)

The main idea here is a cooling solution designed to condition and deliver air directly into the data hall without using ductwork. A Data Air Handling Unit is built to provide large-scale cooling without ducts, often positioned to blow conditioned air into the room from both ends of the hall. This dual-ended supply helps even out temperatures across rows and reduce hot spots, which is especially useful in high-density environments.

The other terms are unrelated to cooling hardware: they refer to roles or procurement functions (like a construction director or an electrical contractor, or a procurement group). They don’t describe equipment, so they don’t fit the scenario of a ductless, end-supply cooling unit.
