On a survey of one of your client's buildings, you discover that one of the TRs, housing a considerable quantity of switching equipment, is at 25 degrees C (77 degrees F) with a relative humidity of 59 percent. This is considered to be:
On a survey of one of your client's buildings, you discover that one of the TRs, housing a considerable quantity of switching equipment, is at 25 degrees C (77 degrees F) with a relative humidity of 59 percent. This is considered to be:
The temperature of 25 degrees C (77 degrees F) falls within the accepted range for normal operating conditions, typically considered to be between 18-27 degrees C (64-81 degrees F). However, a relative humidity of 59 percent is towards the higher end of the acceptable range, which generally should not exceed 55 percent. Therefore, the conditions described are normal for temperature but slightly high for humidity.
TDMM page 3-56 (329) Table 3.5 Enviromental control systems standards for Equipment Rooms. The recommended temperature range listed is ~18 degrees to ~27 degrees celsius (64F-81F). Sixty percent relativity humidity is maximum with a dew point range of ~5.5 degrees celsius (15F) (range 42F-59F) TDMM page 19-4 (1456) Temperature and humidity in the TDR shall be controlled to an operating range of 18 to 24 degrees celsius (64F-75F) with 30 to 55 percent relativity humidity.
Agree with the humidity but not the temp. That is for TEC in Health Care. 77ºF is the optimal temperature for a batteries.
-Answer is Hi Humidity and Hi TEmp : Chapter 19: page 19-3 operating range of 18 to 24 ºC (64 to 75 ºF) with 30 to 55 percent relative humidity
