Temperature and humidity standards for computer room micro-modules

Optimal temperature for computer room micro-modules is around 22°C (71. 6°F) with relative humidity between 30% and 50%, ensuring equipment reliability and preventing condensation or static discharge.

Temperature Guidelines

Computer room micro-modules, including IT racks and semiconductor modules, should maintain a design temperature of approximately 22°C (71. 6°F) at altitudes up to 2150 m (7000 ft.) to provide a buffer for system operation in case of air conditioning failure or fluctuations, as recommended by IBM and ASHRAE standards. Temperature deviations beyond this range for extended periods can reduce equipment reliability and may lead to malfunction.

In data centers, cold aisles are typically maintained at the lowest temperatures, while grey areas for support equipment may tolerate slightly higher temperatures.

Humidity Guidelines

Relative humidity (RH) is critical for preventing condensation and static electricity. For computer room micro-modules: Recommended RH: 30%–50% for semiconductor and sensitive IT equipment.

High R

H (>50%) can cause condensation on surfaces, leading to corrosion or short circuits.

Low R
