Temperature monitoring in computer rooms and data centres is a very important practice in computer maintenance. Computers generate a lot of waste heat as electricity is circulated through them and this needs to be dealt with to ensure system reliability. hệ thống giám sát nhiệt độ độ ẩm
Integrated circuits in a computer (like the processor) produce lots of heat as they are used. This heat floats off to the environment, and so it warms the area inside / around the computer. In a simple home / consumer computer, a small fan is enough to cool off the processor, and the waste heat makes almost no noticeable difference to the room as a whole. However in large data enters the amount of heat collectively put off by hundreds or even thousands of computers can make a very large impact on the surrounding environment. The problem, of course, isn’t just that it gets uncomfortable for staff – it’s that it can affect the computers. If temperatures get high enough, computer parts can start malfunctioning or even melting. Permanent damage can easily be caused to the computers if the temperature gets too high. Even if there is no permanent damage caused to the computer malfunctions can cause permanent or temporary loss of data which can have serious consequences for the business concerned.
Operators of large data centers also have the issues of humidity, smoke, water and continuous power to consider; however heat problems are something that can generally be easily solved. Often the chosen solution is to install air conditioning but this isn’t always the most efficient use of funds and can cause rapid drops and spikes in both temperature and humidity as the unit switches on or off. Establishing where and when hot spots occur and how air circulates and flows around the room are crucial to understanding the heat problem and how to resolve it.
Temperature monitoring systems will help record data about the temperature in and around the computers and will alert staff quickly to problems so that they can be resolved before they affect the long term viability of the equipment.
Considering heat during construction of the data center is important – the server racks should be placed far enough apart that air can flow between them, and this is the best time to install a temperature monitoring system to ensure that a low temperature is maintained and to create alerts should the temperature rise above a set optimum level. The temperature in the room should be, at the very least, little warmer than average room temperature, though cooling it lower than normal room temperature is ideal. In addition to monitoring the temperature of the room as a whole, careful attention should be paid to make sure that each individual computer unit receives enough cooling and stays at a safe temperature.
