In general, the project study has provided the author a vast experience especially during the brainstorming stage where different problems occurred during the performance testing. The author was very glad to the previous theoretical lectures of Dr, Maglaya who was also my former professor in the subjects Advance Refrigeration and Air-conditioning during my undergraduate and graduate class in the De La Salle University. Thru his teachings and guidance, The author was able to apply the theoretical knowledge the author has learned in combating actual job problems experienced in the company. The project was very challenging because of the swift output during the testing and then making the necessary adjustments in order to attain the desired results. In addition, this project is a pioneer project of Chee Puck Refrigeration Inc that gave me a lot of pressure but the author is honored to have the privilege in embarking this task. The major concentration of the project study was to design, fabricate, and conduct a performance testing of stationary freezer using R-404A, a non-CFC refrigerant.

The results of the performance testing shows that the evaporating temperature of negative twenty degree Celsius (–20C) within 25 minutes were reach, which is the main requirements set by Jollibee Foods Corporation to Chee Puck Refrigeration Inc. In addition, the unit case was also subjected to severe physical testing by opening and closing the door with significant pressure on the boundaries of normal usage in order to test the physical toughness of the unit. Results show that the design and fabrication was very tough and formidable because it withstood significant pressures applied to unit case.
