An inverter is a device for converting frequency. The technology is used in many home appliances and controls electric voltage, current and frequency. Inverter air-conditioners vary their cooling/heating capacity by adjusting the power supply frequency of their compressors. This technology saves monthly bill because it bringing about high energy efficiency. An inverter type air-conditioner adjusts the speed of the compressor to control the refrigerant (gas) flow rate, thereby consuming less current and power. An inverter has precise temperature control and as the set temperature is attained, the unit adjusts its capacity to eliminate any temperature fluctuations.

 CHAPTER ONE
1.0                                                        INTRODUCTION
An air conditioners with the inverter technology is the one that is equipped with the new era of inverter compressors. The inverter compressor is capable of running at varying speeds as per the load on the particular electrical appliance. Therefore, there is no extra expenditure of energy even when the load of the AC is less.
The inverter technology in air conditioners is responsible for controlling the given flow of voltage, frequency, and the overall current to the given electrical appliance. Inverter air conditioners are known for varying the respective cooling as well as the heating capacities through the adjustment of the given power supply frequency of the attached compressors. An inverter type of the air conditioners is able to adjust the speed of the machine’s compressor in order to bring about an effective control over the gas (refrigerant) flow rate. As such, lesser energy gets consumed along with lesser power and current values.
When the appliance runs at low speeds, it is able to utilize energy in an energy-efficient manner. This is in contrast to the time when the appliance it running at high speed. An inverter is referred to as a device that is capable of converting frequency in an effective manner. The given high-end technology is being currently used in several electronic appliances including refrigerators, air conditioners, and others in order to save substantially on the overall energy bills.

1.1                                             OBJECTIVE OF THE PROJECT
The objective of this work is to explain the inverter technology being used in air conditioners today.

1.2                                              PURPOSE OF THE PROJECT
The purpose is to see how inverter technology being used in air conditioners can help you in saving your monthly bills.

1.3                                           SIGNIFICANCE OF THE STUDY
The energy-efficient modern-age air conditioners with inverted compressor technology, you can make a consumer or user make wise decision about bringing the home appliance with the same specifications. This would help you save a lot on your monthly electricity bills. Save energy, save money.
The inverter air conditioning units have increased efficiency in contraction to traditional air conditioners, extended life of their parts and the sharp fluctuations in the load are eliminated. This makes the inverter AC units quieter, with lower operating cost and with less broke downs.

1.4                                              STATEMENT OF PROBLEM
The inverter AC units might be more expensive than the constant speed air conditioners, but this is balanced by lower energy bills. The payback time is approximately two years depending on the usage.

1.5             BENEFITS OF USING AN INVERTER-BASED AIR CONDITIONER
Here are some of the potential benefits of buying the revolutionary inverter air conditioners for your home:

• Decrease in the Overall Monthly Energy Bills: You can expect a substantial decrease in your monthly bills that is around 40% less than that consumed by the ordinary non-inverter AC with the single-speed compressor. In a typical inverter AC, once the indoor temperature reaches the predefined temperature, the inverter control adjusts itself to lower capacity operation in order to maintain the overall temperature. This factor makes the inverter ACs highly energy saving than the respective non-inverter AC models.
• Noiseless Operations: In addition to this, the inverted compressors tend to be very silent in their functioning in comparison to the traditional compressors which make a lot of buzzing sound. The modern-age air conditioners would not startle you with their sudden noise as the compressor does not have to undergo the process of starting itself again. The entire outdoor setup of the inverter appliances tends to be quieter in the overall operation when compared to other forms of cooling appliances.
• Unaffected by Voltage Fluctuations: One of the major benefits offered by the inverter-based ACs is that these appliances remain unaffected by the constant voltage fluctuations. This implies that there is less risk of any kind of potential damage to the overall motor of the air conditioner. As such, with inverter AC, you can be convinced of higher durability and lesser maintenance charges every now and then. As a result, the inverter technology in the ACs make them less prone to frequent breakdowns and highly easier to maintain the long run.
• Absence of Shock Loads: As the inverter compressor in the advanced ACs run at a slow speed and in a relaxed manner, there are no shock loads on the overall system. This is unlike the conventional one-speed compressors with the start-stop-start cycle.
• Great Comfort: Another benefit offered by the inverter technology in the air conditioners is the topmost level of comfort offered to the users. The inverter air conditioning systems are best known for their instant chilling offerings along with the top-notch comfort levels offered to the consumers.

1.6                                                 SCOPE OF THE PROJECT
The Inverter technology (DC) is the latest evolution of technology concerning the electro motors of the compressors. An Inverter is used to control the speed of the compressor motor, so as to continuously regulate the temperature. The DC Inverter units have a variable-frequency drive that comprises an adjustable electrical inverter to control the speed of the electromotor, which means the compressor and the cooling / heating output. The drive converts the incoming AC current to DC and then through a modulation in an electrical inverter produces current of desired frequency.
