In the industrial sector, where air conditioners operate continuously for many hours each day, efficient energy use directly impacts operational costs and the working environment of the equipment. This article explores what energy efficiency in industrial air conditioners truly means, the technologies behind it, and how it translates into tangible savings.

The main advantage of analyzing a device’s immunity at the integrated circuit level is that such testing does not require consideration of the influence of the circuit’s design on electromagnetic compatibility (EMC). This analysis includes, for example, the design of the printed circuit board, the nature and availability of connectors, and the enclosure. The article describes the relationship between testing at the device level and at the integrated circuit (IC) level.

EMI (Electromagnetic Interference) refers to unwanted signals that can disrupt the operation of electronic devices. As electronics become smaller and more complex, they also become more susceptible to such interference. EMI can lead to errors, instability, or even system failures. That’s why proper circuit design — including electromagnetic shielding at the PCB level — is so important. This article explains how EMI shielding works, what materials to use, and how to avoid common design pitfalls.

The increase in automation and miniaturization of components makes automation systems increasingly sensitive to environmental conditions. Overheating, moisture, and dust are the main factors that shorten equipment lifespan and lead to downtime.
