What's an inverter? 
An inverter is energy saving technology that eliminates wasted operation in air conditioners by efficiently controlling motor speed.

 

Air conditioners maintain set temperature by cooling when room temperature rises above the set temperature and heating when the room temperature falls below the set temperature.

Motor speed in non-inverter type air conditioners remains constant and temperature is adjusted by turning the motor ON and OFF, which consumes more energy.

In inverter type air conditioners, temperature is adjusted by changing motor speed without turning the motor ON and OFF.

Compared to non-inverter type air conditioners, air conditioners with inverters have less power loss and can save in energy.

When compared with a man running

Non-Inverter Type Air Conditioner

Starting and stopping hard running, resting, then starting and stopping once again uses more energy.

When an appropriate pace is maintained, a runner can continue without wasting energy.

 

How is motor speed controlled?

Motor operates by magnets and electric current.

The motor consist of two types of magnets.

One is a permanent magnet that has a natural magnetic force.
The other is an electromagnet that produces a magnetic force by electricity.

 

The direction of electric current determines polarity of the electromagnet

The north (N) and south (S) poles of the electromagnet are determined by the direction of electric current.

When the direction of electric current is reversed, the north (N) and south (S) poles are also reversed.

 

The motor rotates by switching direction of electric current.

When magnets come into contact, an attractive force occurs between the N and S poles of the magnets and a repulsive force occurs between the N and N poles and the S and S poles.

The motor rotates from the attractive and repulsive forces caused by the change in polarity of the electromagnet.

 

The inverter is used to adjust the speed in which the direction of the electric current is switched, and this regulates the rotation speed of the motor.

The inverter rotates the motor by switching the direction of the electric current of the electromagnet.

Moreover, regulation of rotation speed in a motor is also performed by meticulously controlling the switching speed.

In the context of air conditioning, an inverter regulates voltage, current and frequency to control the operation of the air conditioning compressor, thereby also controlling the output of the unit. Essentially, it is a very sophisticated form of speed control – the higher the frequency the more the compressor works and the greater the output of the air conditioning. Similarly, the lower the speed of the compressor the lower the output of the conditioner.

It is the exceptional control provided by DC inverters that enables these air-conditioners to be highly responsive to changes of temperature in the space whilst delivering excellent energy efficiency.

The Benefits Of DC Inverter Technology

• Faster response to variable heating and cooling loads.

• Significantly reduced running costs (up to 50% saving) compared to non-inverter systems.

• Improved comfort as set-point temperatures are achieved more quickly.

• Improved maintenance of design conditions with less temperature fluctuation.

• Lower noise levels, both inside and outside the building.

• Eliminates voltage peaks from compressor.

• Reduced risk of electromagnetic interference with other equipment.

Benefits Of Inverter Generator

 

The generators have over the years been labeled as bulky and loud electrical tools. But the new electrical equipment known as the inverter generator, is changing all this. Smaller, lightweight and quieter, inverter generators use innovative technology to transforme DC power into AC power with high frequency. The process of transforming the power from DC to AC eliminates any power fluctuations that normally occurs in conventional and older models of generators. Many manufacturers today offer such units on the market, in different sizes and with different power capacity.

While the standard generators operate with constant speed, the inverter generators can adjust the speed according to the power requirements. This means that the inverter generators have engines that can run at variable speed depending on the load. This feature makes the inverter generators to be more fuel efficient and thus environment friendly electrical equipment. The inverter generators are in fact generators that have built-in inverters. The following text will highlight some of the most important benefits of the inverter generators and it will explain why these electrical tools are so widely used today for different types of applications.

High Fuel Efficiency – The inverter generator has the capability to automatically adjust the speed of the engine, in order to produce only the amount of power which is needed for the application in use. The conventional generators usually run at constant speed of 3600 rpm. But the inverter generators can run at slower rpm while at the same time maintaining the power and the frequency. The inverter can reduce the fuel consumption up to 40% because the engine doesn’t run at full speed constantly.

High Quality Electrical Output And Parallel Capability – The technology inverter generators use, enables them to produce power similar to the power which is used in homes. The inverter generator can also be paired with another identical unit. This way the power is doubled. The parallel capability allows you to use two small and lightweight inverters instead of using on big and bulky conventional generator for any type of application, in your home or outdoors.

Maintenance – The conventional and old fashioned generators usually require periodical maintenance in order to provide proper electrical output. This means that oil or fuel that is used needs to be replaced every 200 hours of use. If the generator is not used for more than 30 days, the fuel which is used will drain and the carburetor will run dry. On the other hand, the inverter generators don’t need special treatments for maintenance. They require just inspection of the batteries once in a year.

 

3 Benefits Of Inverter Generators

The inverter generator is a machine used for converting the continuous direct current (DC) that runs in one direction to a standard alternating current (AC) that flows in two directions. The inverter generator can supply steady power which can be used for standard electrical appliances and tools. Powered by diesel, propane, gasoline or natural gas, the inverter generator is a perfect machine for emergency situations like power outage, or for works in remote places where no power outlets can be found. In situations such as power outbreak or outdoor activities, the use of inverter generator is indispensable. When compared with other generator models, the inverter generator is a better choice because it offers more benefits and advantages. Below are the three more important benefits of the inverter generator:

 

 

 

Clean And High-Quality Power – The capability of the inverter generator to produce high-quality and clean power makes it the best choice for powering even the most sensitive electrical appliances such as computers, tablets and smart phones. These devices shouldn’t be powered by conventional generator models because the power which is produced is not clean and qualitative enough. Therefore, the inverter generator should be your number one choice when on the market for a generator.

Lightweight And Portable – The inverter generator can be used for various applications where power is needed, such as construction work, camping and other kinds of outdoor recreational activities. Many households also use the inverter generator as a back up power supply. The huge popularity of the inverter generator is a result of its small size, small weight and portability. The portability is a big plus of the inverter generator. This advantage allows the operator to move the machine easily from one place to another.

Fuel Efficiency – The inverter generator is described as fuel efficient machine that can run for many hours with low costs. This generator comes with capability to adjust the power production according to the power requirements of the appliances that need to be used. This means that if the power requirement is low, the machine automatically decreases its speed and it this way lowers the fuel consumption. The inverter generator enjoys the reputation of being a machine that provides clean backup power which can be used for powering different electrical appliances and electrical tools.
