4th week..

This week I was assigned by Mr.Lau to run CFM with two different types of model for the original unit and the one that has been modified to compare the results. On the 1st day of the test, the result of a modified unit does not meet the required characteristics and low efficiency. Engineers were involved changing the motor used in the fan coil units from 38W to 56W motor 230V and using a larger blower to get better results than the original set. On the 4th day we were able to obtain the desired results and will conduct further tests which is sound test and vibration test. Both tests can only be done at night to avoid the environment sound to get accurate results, and unfortunately I was not able to participate in the test at night because of personal matters that cannot be avoided (",). It is certainly something interesting because it is a new thing for me that I can learn other than the CFM test that I have managed to dominate the theories. However, I still have eight weeks to learn a variety of tests and I will use this opportunity with the best possible. I will upload video(s) and some photos to share at the end of this internship. (Stay tuned! lol ;p) So, that is all from me for this week. Thank you.
