<br/><br/> Air conditioning unit technicians use different kinds of equipment or apparatus<br/>when doing their work to inspect the air conditioning unit. Considering many parameters<br/>such as pressure, temperature, airflow and leak test. As a result, they must bring a lot of<br/>equipments separately and it is a hassle when they are commuting. Fortunately, in the<br/>advent of technology, it can be put together and combine into a single apparatus and made<br/>it smaller and portable. The goal of this study is to develop a portable air conditioning unit<br/>analyzer using microprocessor called Arduino mega and installed on it are different type<br/>of sensors such as thermal, pressure, gas and measuring instruments, anemometer,<br/>voltmeter, and ammeter. It will act as a debugger to show the problem of the air<br/>conditioning unit on an Android tablet. It can also print out the result on a thermal printer<br/>wirelessly via Bluetooth. Today’s existing technology that used in troubleshooting air<br/>conditioning unit focus only in one parameter, existing device such as refrigerant identifier<br/>and smart thermostats for leakage detection. “The Advance Monitoring System for Aircon<br/>Maintenance” determine all important parameters in troubleshooting non-ducted air<br/>conditioning unit such as pressure, temperature, airflow and current rating, the device can<br/>also help in leak detection. The device was tested to 14 air conditioning units, which<br/>compose of 10 units window type and 4 units, floor stand split type, 14 out of 14 the<br/>diagnosis was proven all correct based on the before and after troubleshooting of the<br/>ACU’s. The device able to do its purpose in helping the user to reduce the time in<br/>determining the trouble and to function as all in one device.
