Cold aisle containment (CAC) is a proven data center cooling strategy that creates physical barriers around cold air supply zones, preventing contamination from hot exhaust air and eliminating the energy-wasting effects of air mixing. Hot aisle and cold aisle containment are foundational concepts in data center design. This approach transforms traditional hot aisle/cold aisle. Beyond implementing basic measures such as sealing moisture out of the data center and improving air flow, aisle containment to prevent the mixing of hot and cold air stands out as a method that can dramatically reduce energy costs, minimize hot spots and improve the carbon footprint of data. They published their results in a paper titled, “Data Center 2020: Hot-Aisle and Cold-Aisle Containment Efficiencies Reveal No Significant Differences. ” The title pretty much says it all. So we look to factors other than the economics of efficiency to evaluate the relative merits of the two. Why should the computer room design hot and cold aisles, design principles and how to construct? Why should the computer room design hot and cold aisles? Because the computer room uses the hot aisle and cold aisle to change the previous practice of placing the cabinets in the same direction in the. As you walk through rows of racks, you'll alternate between cold and hot aisles. You'll hear expressions like “CRACs”, “PUE”, “White Space”, “Cold Aisle Containment”, “Hot Aisle Containment”, and many more.
