Analyzing the effects of aisle capping in the server room!
In server rooms and data centers, there are many servers and IT equipment, and heat management is essential for their stable operation. As a measure, we face the exhaust fans on the back of the server racks towards each other to create a pathway (hereinafter referred to as the hot aisle) that primarily directs exhaust from the racks upward, and we face the intake sides on the front of the server racks towards each other to create a pathway (hereinafter referred to as the cold aisle) that primarily introduces cool air from the floor into the server racks, alternating them to enable efficient exhaust. However, at the top of the server racks, there is a possibility of drawing in high-temperature exhaust from the equipment (short-circuiting), so we considered measures and conducted a comparison based on the presence or absence of a partition (hereinafter referred to as aisle capping) at the top of the cold aisle.

basic information
【Analysis Model and Conditions】 - The size of the analysis model is 23m × 16m × 3.8m, with a grid count of 425,375. - The interior features a raised floor, with 8 air conditioning units installed. - Server racks are arranged to form hot aisles and cold aisles. - The heat generation condition is solely from the servers, with a total heat output of 440,000W. - The air conditioning system blows cold air from the bottom of the units into the space beneath the floor and draws air in from the top of the units. - The total airflow is 160,000m3/h, with a discharge temperature of 17°C and a set room temperature of 24°C. 【Analysis Results】 - The air conditioning air from beneath the floor is observed being supplied to the racks from the cold aisle side and exhausted to the hot aisle side. - Without cold aisle containment, there are high-temperature areas above the server racks. - With cold aisle containment, there are no short circuits above the servers. - Cold aisle containment can prevent short circuits. - Cold aisle containment allows for the maintenance of temperature within the cold aisle. → Cold aisle containment is effective in suppressing temperature rise above the server racks. ● For more details, please contact us or download the catalog.
