We must have proper water flow in order to keep the Delta T between the minimum and maximum allowed by the Aermec factory.
We use Magellano to provide selections, if you do not have Magellano please email email@example.com and we will run the selections for you.
If we have very low water flow the Delta T becomes much too large and compressors start cycling on and off rapidly causing failure.
If the water flow is too high the Delta T becomes too small causing compressor cycling and failure.
The engineers design parameters affects the system water flow calculation overall.
Proper water volume is needed in order to guarantee proper operating time of compressors, if the volume is too small the compressors will cycle rapidly causing failure. Rapid compressor cycling is a symptom of low water volume. In order to find out the correct water volume we have a System Water Volume Guide on our website.
If the system is used for process cooling / heating or comfort cooling / heating is the main consideration but we must also look out for unbalanced loads at different times of the season. If loads will be extremely small larger water volume must be used.
The following must be considered when designing a system:
