Current measurement as the key to efficiency
Air conditioning systems have become an integral part of our daily lives. They ensure pleasant temperatures in living and working spaces in hot climates and during the summer months. An important factor for the efficiency and reliability of air conditioning systems is precise current measurement, for which Isabellenhütte has the corresponding portfolio of precision resistors and sensors.

Increasing the efficiency of air conditioning systems
The use of air conditioning is necessary to ensure comfort and increase productivity, especially in areas with extreme temperatures. In addition to cooling, modern air conditioning systems can also purify and dehumidify air, which contributes to a healthier indoor climate.
By monitoring the current flow in the various components of the air conditioning system, such as compressors and fans, energy consumption can be optimized. Current measurement enables precise control of motor performance and helps to detect and correct inefficient operating conditions at an early stage. This leads to higher efficiency, lower operating costs and a longer service life for the appliances.
