Why We Need Precision Air Conditioner Units?
Information processing is an indispensable part of many important tasks, therefore, the normal operation of a company cannot be separated from a constant temperature and humidity data room. IT hardware generates unusual concentrated heat loads, while also being very sensitive to changes in temperature or humidity. Fluctuations in temperature or humidity may cause some problems, such as garbled code during processing, and even complete system shutdown in severe cases. This will bring huge losses to the company, depending on the system outage time and the value of the lost data and time.
The design of standard comfortable air conditioners is not intended to handle the heat load concentration and composition of data centers, nor is it intended to provide the precise temperature and humidity setting points required for these applications. The design of a precision air conditioning system is to achieve precise temperature and humidity control. The precision air conditioning system has high reliability, ensures continuous operation throughout the year, and has maintainability, assembly flexibility, and redundancy, which can ensure the normal operation of air conditioning in the data room throughout the year.
Design conditions for temperature and humidity in the computer room
Maintaining temperature and humidity design conditions is crucial for the smooth operation of the data center. The design conditions should be between 22 ℃~24 ℃ (72 ℉~75 ℉) and 35%~50% relative humidity (R.H.). Just as improper environmental conditions can cause damage, rapid fluctuations in temperature can also have a negative impact on hardware operation, which is one reason why hardware needs to maintain its operational state even if it is not processing data. On the contrary, the design of a comfortable air conditioning system is only aimed at maintaining indoor temperature and humidity at 27 ℃ (80 ℉) and 50% R.H., respectively, under summer temperatures of 35 ℃ (95 ℉) and 48% R.H. external conditions. Relatively speaking, comfort air conditioning does not have a dedicated humidification and control system, and simple controllers cannot maintain the required set point for temperature (23 ± 2 ℃), therefore, high temperature and humidity may occur, leading to a large range of fluctuations in environmental temperature and humidity.
Problems caused by unsuitable computer room environment
If the environment of the data room is not suitable, it will have a negative impact on data processing and storage work, which may cause data operation errors, downtime, and even frequent system failures leading to complete shutdown.
1. High and low temperatures
High temperature, low temperature, or rapid temperature fluctuations may disrupt data processing and shut down the entire system. Temperature fluctuations may alter the electronic and physical characteristics of electronic chips and other board components, leading to operational errors or malfunctions. These issues may be temporary or may persist for several days. Even temporary problems can be difficult to diagnose and solve.
2. High humidity
High humidity may cause physical deformation of the tape, scratches on the disk, condensation on the rack, paper adhesion, MOS circuit breakdown, and other faults.
3. Low humidity
Low humidity not only generates static electricity, but also increases the discharge of static electricity, which can lead to unstable system operation and even data errors.
