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.

3rd week..
It's my 3rd week now. I think the time in this week seems long because my supervisor had gave me some works and I did on my own without pairing with Mr.Bakri anymore. At first, I was "Ok omg disaster coming and building gonna explode!" haha Well, I admit it was very nervous when running a test alone in the test room. lol. But it became better after being given a guidance and I have learned well. Just need to keep the work in the lab done by safety features that has been set to avoid the things that are not desired.
I have been asked to run a test on a fan coil unit to get the maximum CFM on high speed and minimum CFM at low speed. There have a suction blower for maintain the pressure from the blower of fan coil. Inside the suction blower have few types of nozzles that applied together to set the pressure value and each of the nozzle use at a certain pressure level to get the air velocity and shown from a device called manometer. I also need to read the barometer reading that is a constant and speed of the fan coil need to be taken by using a device to record the RPM.
Well ya, since I am still a "newbie", I cant done the test as fast as Mr. Bakri that has been work for CISB for almost 10 years. rofl xD That make me feel to learn more and will improve my skills to do a test with more lesser the percentage error (",) That's all I can share until now and will update again next week. See ya! (^,^)

2nd week xD
haha! First of all sorry I'm not telling what happened through a day by day on my internship programme. I have decided to update my activities week by week :p Well, this is my 2nd week doing my industrial training, still have 10weeks more! (",)
Ok, on Monday, my department has done a test on a fan coil to find their best air flowrate or we call it CFM (Cubic Feet per minute) if I'm not wrong lol xD Well, we are trying to get the CFM around 1400. Our first attemp was failed, we got 945.45 CFM by applying 230V. So we try to increase the voltage but we was failed again since we got 963.138 CFM. After the team has discussed they decide to K.I.V for the test and will recalculate the target CFM again. At the evening, I have been asked by my supervisor to proceed with the Success Story. I need to finish the description for every types of improvement that has been done.
For 2nd day, Tuesday, my team still proceeding with the CFM test but now with a different model of fan coil. The model type is 42 CGT004 manufactured by the company. Now we need to get its CFM around 400. On the test at the suction blower part, we used 1x4" nozzle size with 0 static pressure and 50hz of frequency. First attempt we got 335.68 CFM with 220V. So we try again with 230V and still failed, CFM was 340.421. Third try we use 240V we still couldn't get the CFM target which is only 347.21. So we discuss again and ask some other engineers to recalculate the theoretical value because they might have some problem occurred and we cannot proceed with the test. At the evening, I went to collect data from the AHU unit to find the width, length, height, pressure and discharge area. In order to obtain the leakage in L/s and L/s.m². The objective is to reduce the leakage on the AHU unit. After done with the data, I went to the site (factory) and look how the workers operate and manufacture all the units. I'm so impressed when all the workers there do respect to engineers even I'm still a trainee lol xD
On Wednesday, there are no much work I did, just continue with the sweat test but only set up the device that need to be test. Now we applied new method and see how it works to reduce those sweating. We attached the AHU panel with a foam to reduce sweat on outside surface.
Thursday I was off because off sick. I got fever and flu that caused headache :-(
Friday I came back and feel a bit okay without fever but still have flu. Luckily we have no test to do on this day and I just helping the engineer to improve safety in our lab such as put the wire on the wall inside the channel and install the pipelines for water that has been condensed by the air conditioner located on the ceiling and finish work at 5.15pm.

3rd day..
Woottt..!! It's Friday! It means that tomorrow is a holiday! lol xD Well anyway, I still do sharing what I have done today. Firstly I want to apologize for the one day delay to write this blog, regarding I went back to my hometown and I reached at midnight and I was so tired after 3 hours driving plus 8 hours working at day. Lets proceed this anyway.
On my 3rd day, our team are still looking forward on how to reduce the sweat occurred on the AHU unit. By a research, those sweating will make the thermal efficiency inside the AHU unit become lesser. So, today, the engineers decide to remove the gasket enterpost that previously attached with the aluminum interpost on the AHU body unit and start collecting data. While waiting the machine to record the data, I have been asked by my supervisor, Mr. Lau to keep in data of items that stored in the lab. The purpose of making that is to ensure all equipments and machines can be use properly to avoid hazardous. I do that until Friday's Prayer break at 12 o'clock. After the break, Mr. Bakri has taught me on how to use the machine and system as being run to collect the result. He also told me how to fill up the table for a particular testing. There are many tests can be run in the lab as I remember such as sound test, vibration test, ducting test, sweat test of course, and so forth.
After we got the result on the sweat test, Mr. Lau has give me an assigment to do a "Success Story" lol. What do you think when first hearing that verse? xD Well, success story is about a report of safety improvement quality in the lab. EH&S department officer will do an inspection around the building to keep safety on top condition. How to write the report? The main thing is picture before and after the prevention on a certain place. For an example, previously there are no "Safety Glass Area" sign and after the prevention, they build the sign and took pictures before and after. After finish the report, I return back to Mr. Bakri to join him on the sweat test data analysis and finish work at 5.15pm.

2nd day..
Yeah! This is my second day of working as a trainee. I'm getting closer to fully adapt the way of work here. The workers are also a nice person and willing to teach me how to do this and that even the simple things (lol). Well, today I followed Mr.Bakri (Mr.Lau's Assistant) to continue the research that we did yesterday and we found a new method on how to decrease the sweat on panel and it's aluminum interpost. We proceed with a test in the lab and after the test specimen has been setup, we start to collect all the data. We have two specimens to do a comparison between normal assembly and panel with superlon gasket. The objective of this test is to decrease as good as can sweat on the panel and aluminum interpost body so that the efficiency will be increase. I'm so impressed on how the engineers discuss and do the job. Tomorrow the team will proceed with new idea to overcome those sweating.

1st day...
Today was the first day of my internship program. I should be scheduled to start training on Monday, 5th April 2010, but for some reason, I was asked to start training today, Wednesday, 7th April 2010. I am currently undergoing internship program in an air-conditioning supplier Carrier International Sdn Bhd (CISB) located in Section 2 Bangi, Selangor. Last Friday, the employer has given all the safety equipment should I wear when I was at work, such as safety boot and safety glasses. In addition, I was given a pair of uniform standard of engineers working in this company.
Before starting work, I was briefed with safety features to be observed while on duty and prohibited areas and dangerous areas. Once finished, I was introduced to Mr. Lau is an engineer who will train me during the program. I was placed under Production Development department. This department has a laboratory test that will test, modify and improve the quality of the product. It is equipped with machines and tools are sophisticated and easy to handle. Today I participated in an experiment to increase the thermal efficiency in accordance with the requirements of its customers. Although a bit awkward at first, but after the guidance give by Mr. Lau, I was able to understand the concept of the test today. In honestly, I am comfortable with the treatment given by Mr. Lau and several other engineers. Hope I will enjoy my entire internship period until end.
