When frost accumulates, it can block airflow, reduce system efficiency, and increase energy costs due to frequent, often unnecessary defrost cycles. Recognizing this issue, our team set out to develop a smarter solution: The Defrost Sensor.
Traditionally, refrigeration systems rely on timer-based defrosting, where defrost cycles are set to activate at regular intervals, regardless of actual frost levels. This system doesn't "know" whether frost has formed or not - it simply triggers defrost based on time alone. As a result, energy is often wasted on unnecessary defrost cycles, contributing to increased costs and reduced efficiency.
Our Defrost Sensor was designed specifically to address this problem by only defrosting when necessary. Using advanced technology, this sensor measures the difference between air and ice, allowing it to detect the actual presence of frost. When ice begins to form, the sensor triggers defrosting just as it’s needed, avoiding unnecessary cycles and saving energy.
For the Defrost Sensor to function effectively, correct installation is key. It should be placed where ice typically builds up on the evaporator. This positioning ensures accurate readings and optimal performance, making each defrost cycle as effective as possible.
The benefits of switching from timer-based to demand-based defrosting are clear. For instance, Arla, a major dairy company, implemented our Defrost Sensor and saw impressive results. They reduced their defrost cycles from 8 times a day to just once, leading to significant energy savings and improved system efficiency. This reduction in defrost frequency means not only less energy consumption but also a longer lifespan for the evaporator, as it undergoes less thermal stress.
