The inverter air conditioning is the latest technology in the HVAC field that is becoming more popular due to its environmental friendly and energy savings approach. Providing comfort to the users is another big advantage of this kind of system.
Traditionally, the compressor that is used in an air conditioning system is an ON or OFF type in that it either works at the maximum capacity or none at all. It ON when the room thermostat calls for cooling and OFF when the desired temperature has been achieved. This cycle is repeated with the change of load in the room.
Electronic Controls for control of Inverter Air Conditioning DC Inverter Compressor.
The advancement in power electronics has enabled the inverter technology to thrive by the use of microcontroller and IGBT modules to drive the compressor DC or AC motor. The speed of the compressor motor can be varied by using the variable frequency drive.
This is done by converting the incoming AC supply to DC voltage and then modulate it by changing the voltage, current and frequency of the power to the compressor. Changing the frequency changes the speed of the compressor by using a more complicated electronics control circuitry.
Advantages of Using Inverter Technology
Keeping abreast with the latest technology has more advantages than remaining status quo. Here are some of the reasons why you should consider buying an inverter air conditioning system.
A study by Daikin(FTK-1115-B Brochure) on the energy saving obtained over a period of 1 year between a 1.5 HP inverter vs a 1.5 HP non-inverter showed that there is a big significant of savings achieved on the inverter unit. The units were tested in a room size of 16.5 square meter, set temperature = 25°C, Fan Speed = High and outdoor temperature = 33°C.
Daily operational hours = 8 hours.
Disadvantages of Using Inverter Technology
Typically, the disadvantages of using inverter air conditioning driven system is due to cost. Here are a few reasons why the cost is higher compared to the non-inverter system.
Visiting HVAC events and trade shows are one of the best way to equip yourself with the latest happenings in the air conditioning and refrigeration field. See the listing of events for year 2017-2018.
Find out what chilled water air conditioning is. It is usually used in applications that need large cooling capacity though smaller units are becoming popular in residential applications.
Process Cooling has enabled industries such as textile, plastic mold injection, food processing, packaging and medical to thrive.
