Improvised Air Conditioner

I. INTRODUCTION

Air conditioner is a device for cooling and controlling the humidity and purity of the air circulating in a space.

As day time is starting to become more and more unbearable, as fans would only constantly stir the hot sticky air around, so the researchers ended up in choosing this topic. The researchers chose this topic mainly because of the hot weather here in the Philippines especially here in Cabanatuan City that has an average temperature of twenty nine point ninety five degrees Celsius (29.95 ºC). The constant high temperature was the main reason this came up to the researchers’ minds. This particular design is a low-maintenance version that requires no water drainage. The materials needed to conduct the product were also cheap and easy to find, which was very sufficient for people to make.

II. OBJECTIVES

The objective of the improvised air conditioner is to help people to make the weather little more bearable. Not only that, but it aims to substitute a high class and expensive air conditioner to make it affordable, easy to make, rather effective, portable and reusable. The purpose of the project is to provide a cool air without consuming a lot of electricity. At the same time, it may help the users to cool their drinks while using it. In addition, the researchers intend to identify which voltage can give the lowest temperature, slowest melting time, the highest percentage of relative humidity and what is best to use.

III. MATERIALS AND METHOD

Materials used

Researchers used the following materials

1. DC brushless fan - used to ventilate the ice.

2. Elbow PVC pipe – used for the air passage.

3. Digital thermometer with external probe – used for measuring the temperature coming out from the pipe.

4. 1000 mA Adaptor – used for changing the amount of voltage.

5. Styrofoam ice box – used for preserving the ice.

6. Cutter – used for making an opening to the box.

7. Electric tape – used for...
