Inverter technology in the air conditioning system is the ability to monitor and regulate the heat transfer by adjusting the speed of the compressor in accordance with the demand.According to DAIKEN a leading manufacturer of HVAC systems in Europe, inverter technology can be compared to the technology in the car "the harder you push the accelerator the faster you go". This innovation in air-conditioners was first introduce by Toshiba on 1981

Power factor controller have different types that are optimized to served specific requirements in the industry. Power factor controllers are the heart and brain of operation for power factor correction which is a kind of energy saving methods. In this topic I am going to discuss on how to install the power factor controller. These are the steps:

The energy star is a program that was conceptualized by John S. Hoffman. This program aimed to promote energy conservation among equipment manufacturers

In alternating current system (AC) we are dealing with three types of power. These are the following:

1. Real power (P) by which its unit is expressed in watts (W).

2. Reactive power (Q) by which its unit is expressed in reactive volt-amperes (VAR).

3. Apparent power (S) by which its unit is expressed in volt-amperes (VA).
