What the shared parts are
- Coolant distribution units — The unit that separates the IT-side (technology) coolant loop from the facility water loop, exchanging heat between them and pumping and filtering the technology-side flow — sized from in-rack and in-row units up to multi-megawatt facility-class units.
- Chillers & compressors — Chillers use a vapor-compression or absorption cycle, built around a compressor, to produce chilled water for the facility's cooling loop.
- CRAH / CRAC / fan walls / in-row units — CRAH, CRAC, fan-wall, and in-row units circulate conditioned air across IT equipment in air-cooled halls, using either facility chilled water (CRAH) or an internal refrigerant circuit (CRAC).
