Let's move to the next page and see what effect the fans have on the thermal performance of the cooler. These charts here are important, as all fans get the same amount of voltage, and here you can see what fan offer the best airflow. That FLX is seriously pushing move serious airflow.Īnd again, ranking wise all things remain roughly the same, at 12V the FLX was able to move 3 meters of air per second. Yeah, interesting - the ranking hardly changes much in the ranking with normal voltage settings. But let's move to more normal settings applied. You'll notice immediately that the two A12X25 fans actually are already in the lead here. At this low voltage setting, the higher the number the better. Description: This robust temperature and climate test chamber raises the industry standard to ease operation, performance, and reliability. The best performer running upwards to 1.7 m/s is the A12X25 FLX. The instructions for nozzle tuning with the forms for recording your data. There is also manuals for fuel nozzles, fuel filters, auxiliary pumps and injection nozzles. For cooling, Delta T is calculated by subtracting. The first is to calculate the delta T across the evaporator coil by measuring the air temperature entering and exiting the evaporator coil. There are two easy ways to check for evaporator performance. As you can immediately spot, the two (extremely silent) low RPM fans so perform the worst, starting at 1 meter of airflow (BFT) for the Redux 900 followed closely by the A12X25 ULN. This page contains Order forms for Airflow performance and Bendix fuel control overhauls. Here are three tests to check for performance and correct airflow across the coil: 1. It defines four Tasks - A, B, C, and D - and dictates the order in which they have to run, and which tasks depend on what others. We start off with 4V with the ULN adapter again. A DAG (Directed Acyclic Graph) is the core concept of Airflow, collecting Tasks together, organized with dependencies and relationships to say how they should run. Now we can measure how much air the fan is sucking inwards, the value is measured in meters per second, higher is in this metric better, of course. Each fan is measured with the Anemometer positioned precisely as shown above. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology. It's a relatively cheap device to get and does seem to provide pretty steady results. With the help of a simple to use Anemometer, we can see how airflow behaves. An anemometer is a device used for measuring the speed of the wind, and actually also is a common weather station instrument. But we can get a good indication of airflow per fan at each setting. We'll now place a focus on airflow, and while a totally precise measurement, I'll classify this page as somewhat subjective. On the previous page, you have been able to see the acoustics per fan configured at a selection of three settings.
