WebFeb 4, 2024 · Electrical Equipment Likes the Cold. Operating systems tend to generate a lot of heat. Because of this, your equipment is much more likely to thrive in a colder environment than a warmer one. Too much heat can cause a meltdown both internally and externally, which is why most equipment tends to come with a built-in fan. The primary source of heat comes from the electrical equipment itself within the enclosure. The second law of thermodynamics puts a limit on the amount of useful work that can be derived from a machine; it follows that no system can operate at 100 percent efficiency. Thus, the remaining energy is used to … See more The lifetime and failure-free operation of electrical equipment is strongly dictated by environmental conditions and the mode of operation.
