Mass Flow Rate with Big Condenser

[Sergei]

This is what I do for a living. If you are lucky to do this before the system is built it is so much easier. If you have to do it after installation it is a lot of work.

There is an optimum for each operating condition. The real trick is to find these operating points and match the system response to these with the most cost effective method of operation.

Hi, Mike.
I agree with you.
There are 2 types of optimization. Optimum design and optimum operation. Optimum design is the foundation of optimum operation. However, optimum operation is the final goal of energy saving process. Two steps should be done for optimum operation.
1. Determination of optimum set points and operating strategies for different ambient conditions and different refrigeration loads. Very often we just guessing about these points and strategies. This is the most difficult part of optimization. However, how we can reach the goal if we don't know what is it.
2. Implementation of optimum set points and optimum operating strategies. Sometimes, we don't know how to implement these set points.
