Introduction Comfort or industrial air conditioning may have begun when fire was used by man to warm himself. Subsequent development of environmental control included open fire places, furnaces, stoves and the like. The first air conditioning system was designed by Wilis H. Carrier in New York, where it was used to improve the printing quality in a publishing company through thermal and humidity control. Then came the development of self-contained units, where the refrigeration and air conditioning components are put in one factory-enclosed package. A larger split type (the evaporator is separated from the compressor and condenser) units are now used in stores and restaurants. Eventually, new markets for air conditioning of residences opened and are now progressive. Large hotels with the big function rooms, auditoriums, theaters, gym, condominiums, department stores, and other buildings with large space use the centralized air conditioning system. In educational institutions, physical facilities upgrading help achieve excellence in instructions. Laboratories and libraries are being air conditioned to make them more conducive to research and learning. Malfunctions of electronic equipment have decreased and feedbacks on laboratory learning processes have become more satisfactory. However, a new problem arose when students, parents, and teachers clamored a better condition during major activities such as graduation rites, institutional religious celebration, and other activities inside the gymnasium, where more than 4,000 people could attend. Heat exhaustion is the common ill effect on grade school pupils and even female college students with low resistance to rapid thermal changes. This usually occurs during summer, or when outside atmospheric temperature is high. There are times when graduating students attending graduation ceremonies would leave the venue due to heat exhaustion. Administrators cannot force those students to stay because there were already incidents of fainting, vomiting, irritability, and other abnormal physical discomfort during similar activities as mentioned above. Now, if the air conditioning systems are in place, return on investment can be obtained from rentals during major concerts, sports, and other fund raising activities. These activities are usually scheduled on weekends so that they will not conflict with the academic activities of the school. Statement of the Problem This study aims to explore the feasibility of installing a centralized air conditioning system for the Colegio San Agustin- Bacolod Gym-Auditorium. The study seeks to accomplish the following problem objectives: [1] The air conditioning to be installed shall produce the desired ideal comfort conditions as designed. [1.a] Data and estimates measured represents typical values. The technical information used in the calculations shall give valid outcomes. [1.b] Items that could not be estimated or are not accessible realistically have assumed values that shall yield ideal and optimal results. [2] The study when applied shall function as expected. The system will perform as prescribed for the school’s clientele and the Negros Occidental community as a whole. [3] The technical facts resulting from the study can be used as basis by other educational institutions in search for better physical facilities for sports, cultural, and academic activities.

The refrigeration industry in the province of Negros Occidental is suitably greater in extent and is varied. Presently, refrigeration is essential in many phases of the production, preparation, storage, and distribution of various foods and beverages. The development in this particular industry is occurring rapidly that it is difficult to keep abreast of them. The town of Victorias and its neighboring towns and municipalities greatly affected the economic situation of the people, particularly those of the fishing and prawn industries. Because of the increase and demand, people are not contented with the presence of existing plants. There should be an additional establishment of an ice plant to overcome the tremendous growth of fishing industry in Victorias and nearby towns. The manufacture of ice is still one of the principal needs of refrigeration engineering and will continue to be for the time to come and ice is the cheapest means of short-time preservation of food, if the amount used is nominal and if the locality can furnish it at a reasonable price. As the cost of ice is an important factor, a vast amount of research has been put in to develop an expensive means of manufacture. General information A. Name and location of the firm. The name of the project shall be VICTORIAS ICE PLANT. The plant site and office will be at the Barangay 13, beside the National Highway near the Malihao river, Victorias, Negros Occidental. The name gives the idea where the plant is situated. Thus, the town people have greater tendency to patronize the product because it bears the town's name. B. Brief description of the project. 1. History and Objective The proposal of an ice plant in Victorias came about after studies shown that there is highly a lack of supply of ice in the town of Victorias and other nearby towns as well. 2. Nature of Industry Fishing, as well as prawn industry and other related agro-industries, is vastly growing in the Northern portion of Negros Occidental. For preservation purposes, those products need ice as their primary tool. Also, commercial and household sectors use ice for consumption purposes. The presence of an ice plant will attract both big and small-scaled investors to invest in certain profitable and related industries. 3. Organization of the Project The proposed ice plant is a corporation composed of a group of people with an estimate total manpower requirement of 48 persons. The plant operates 24 hours daily with a three-shift schedule.

This study aims to compare the result of the computer programs and slope deflection method for the structural analysis of frame. The computer programs being referred are MICROFEAP-II (P1 Module) and RISA-2D (R) Version 3.00. The frame structure consists of six structural members wherein only the end moments derived from using the computer program and slope deflection method are taken for the statistical analysis. There are twelve end moments in each method of structural analysis and are considered as correlated samples because they are being individually matched after administering the methods. The end moments of computer programs and slope deflection method are referred as X-variables and Y-variables respectively. The statistical tools employed are the Mean, Standard Deviation, t-test for testing the hypothesis and Pearson’s Correlation Coefficient to determine the relationship of two variables. It was found out that the two computer programs generate the same results. Moreover, there is no significant difference between the resulting end moments derived from using the MICROFEAP-II (P1 Module) and RISA-2D Version 3.00 to that of Slope Deflection Method. The correlation coefficient of two variables is +1.0 which is a perfect positive relationship.

Thermal insulation is a material of low thermal conductivity. It is used primarily to provide resistance to heat flow. Clay, rice hull and wood ash were utilized as raw materials for the manufacture thermal insulation in the form of fired bricks. Brick dimensions are 250 mm by 250 mm by 30 mm. Five different proportions by mass were produced. One face of the brick was subjected to heating and temperatures of both faces were measured. Heat source was from a Bunsen burner. From these data, the temperature difference between opposite faces was computed, tabulated, and analyzed if there was significant difference among means. Recording of temperature was done at the end of every thirty seconds. This temperature difference was an indication of thermal resistance (a property of an insulation) based from Fourier’s law of conduction. Test for strength of brick was done on a UTM. Samples tested were new ones that did not undergo heating. Ultimate strength was the variable measured as all brick samples did not show yield point Abstract only 2008-01-01T00:00:00Z
