🔧 What does an EEV do in HVAC systems? This little device, known as the electronic stepper motor, EEV (Electronic Expansion Valve), or electronic metering device, controls how much liquid refrigerant moves through the system. The liquid line comes in, gets metered, flows into the distributor and tubes, passes through the coil, and returns to the suction side before heading back to the compressor. So, an EEV is a type of electronic metering device, which more precisely controls the refrigerant f

Have you heard of something called “natural defrosting”? ❄️ Cooling systems with room temperatures above freezing, such as 5 °C, can defrost naturally, removing the need for additional heat. In smaller systems, you can leave the evaporator fan running. 🎥 You can see how it works in our animation. 🔗 Learn more about defrosting here: https://bit.ly/49pxgcu #Animation #Defrosting #Refrigeration #CoolingSystems | Danfoss Climate Solutions

🧐The small pump that detects water levels 💧This small pump with a magnetic reed switch helps detect when water levels are full and pushes it out, moving water out quietly and efficiently. But here’s the catch, if it’s installed incorrectly, the suction power won’t be strong enough. That means: too low, and the suction is weak; slightly above, and it stays primed for steady drainage 🚿 These pumps are great for mini splits but not recommended for larger split systems due to limited capacity. 💬

Meet the self-taught inventor who revolutionized modern refrigeration. | History Vault

In 1938, Frederick McKinley Jones revolutionized food transportation with his invention of the first successful mobile refrigeration system. Born in Covington, Kentucky in 1893, this self-taught engineer created a mechanical cooling unit that could be mounted on trucks, ending the era of using ice for food transport. 🚛 His invention, the Model A, transformed the way America ate. Before Jones, trucks could only travel short distances before food spoiled. His mechanical cooling system allowed fre
