Working of inverter ac

It's really very interesting. All the description given are taken from catalogues of mitsibushielectric and daikinindia.

2. CONTENTS INTRODUCTION HOW IT WORKS SIGNIFICANCE COMPARISION CHART

3. WHAT IS INVERTER ?   Inverter , is an electronic device or circuit that changes  direct current  (DC) to  alternating current  (AC).  PURPOSE OF AC Air conditioning  is the process of removing heat and moisture from the interior of an occupied space, to improve the comfort of occupants. 

4. INVERTER AC – HOW THEY WORK Inverters electronically control the electrical voltage, current and frequency of electrical devices such as the compressor motor in an air conditioner. They receive information from sensors monitoring operating conditions, and adjust the revolution speed of the compressor, which directly regulates air conditioner output.

6. SIGNIFICANCE OF INVERTER MODEL 1. Vector-Wave Eco Inverter This inverter monitors the varying compressor motor frequency and creates the most efficient waveform for the motor speed. As the result operating efficiency in all speed ranges is improved ,less power is used and annual electricity is reduced.

7. 2. Joint Lap DC Motor This innovative motor operates based on a high density, high-magnetic force, leading to extremely high efficiency and reliability.

8. 3. Magnetic Flux Vector Sine Wave Drive This drive device is actually a microprocessor that converts the compressor motor’s electrical current waveform from a conventional waveform to a sine wave to achieve higher efficiency by raising the motor winding utilization ratio and reducing energy loss.

9. 4. Fuzzy Logic “I Feel” The fuzzy logic control system adjusts conditions which suits the occupants. The selected temperature is stored in the memory system and reproduce automatically each time the air conditioned machine is operated.

10. 5. Heat Caulking Fixing Method This is a type of welding method which is newly used in inverter model to fix the internal parts, which replaces former electric spot arc welding method. Due to which the distortion of internal parts is reduced and hence higher efficiency is realised .

11. 6. PAM (Pulse Amplitude Modulation) It is a technology that controls the current waveform so that it resembles with supply voltage wave, thereby reducing loss and more efficient use of electricity. Using PAM control, 98% of the input power supply is used effectively.

12. Merits of PAM Significant energy savings Remarkable reduction in power loss saves electricity. Power increased Efficient current increase realizes increased power.

13. Compressor - A Compressor is a device that increases the pressure of a gas by reducing its volume.

14. Condenser - A  condenser  unit  has a heat exchanger section to cool down and condense incoming refrigerant vapor into liquid.
