Abstract
Air Conditioner(A/C) is a system of air conditioning which serves need of thermal comfort inside a room. Until now, to determine COP of A/C is performed measurement of temperatures and pressures in A/C. Then, it is continued by calculating of COP. Unfortunately, the process take much time. Therefore, it is important to find any new method to obtain COP. In this paper, to solve the problem was designed a COP monitoring system. To do this, the Arduino Uno was uploaded a program of the monitoring system. The system was equipped sensors. And then to display COP was used a Laptop. The results showed that by using the proposed method and the traditional one, it was obtained that COP actual fluctuates about 3.0 in range from 3.14 to 3.51 and 3.2 to 3.5, respectively. In addition, it was predicted that the using of proposed method in illustrated situation can save time by 2 hours or 80%. It can be considered as a promising solution to determine the COP quickly and easily .
