What is the Inverter technology in air conditioners?

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. A microcontroller can sample each ambient air temperature and adjust … Click here to continue…..

Myths about Inverter AC

Myth 1 – They consume more power because the compressor runs continuously The inverter AC was invented to solve the issue of reducing consumption of electrical energy. That the compressor is continuously in operation is a statement of fact, but the power consumption is substantially lower than that of a conventional fixed speed AC because the variable speed drive regulates the frequency of current supplied to the compressor thereby bringing down power consumption. Myth 2 – They are less efficient than conventional fixed rate AC After initial cooling, the conventional AC idles until the room temperature rises and then the … Click here to continue…..

Inverter AC

An inverter AC will ordinarily cool the room to the desired temperature faster than a fixed speed AC, but that may not make a significant difference in power consumption. Once the room has been cooled to the pre-set level, the compressor will operate continuously, but the variable speed drive will supply just enough power for the compressor to maintain the temperature at the set level. The compressor will consume only 1/4th of its rated power output. Thus, a 1.5KW (1500W) compressor will operate at 375W consumption to maintain the desired temperature.

Conventional Fixed Rate AC

At start up, during the 20 minutes it takes to cool the room, the compressor will be operating at full capacity and the fan will also be in operation. The compressor will switch on and run when the temperature rises and switch off when the room has been cooled again every 10 minutes. Accordingly, in the first hour, the compressor and fan will be in operation for 40 minutes, and only fan will be in operation for 20 minutes. For the remaining 9 hours, in every hour, the compressor and fan will run for 30 minutes, and only the fan … Click here to continue…..

Benefits of Inverter AC

Maintains Steady Temperature : Conventional AC operates in cycles; cooling the temperature to the thermostat level, switching off, and then restarting when the temperature level rises. The ambient room temperature is, therefore, subject to variations. Inverter AC operate through a variable speed drive that controls the supply of power to the compressor to maintain the room temperature at the pre-set comfort level thus avoiding temperature variations; Less Stress on Compressor Motor : Each time the compressor commences its operating cycle there is considerable stress on its motor to go from a state of inertia to full speed. This adversely affects … Click here to continue…..

Normar (Conventional) AC vs Inverter AC

Factors Conventional AC Inverter AC Electric Current Operates purely on alternating current (AC) Initial supply of alternating current is converted to direct current and back to alternating current at the required frequency Running of Compressor The compressor operates in cycles. It cuts off when the room temperature reaches the level set on the thermostat. It restarts when the room temperature rises. The compressor is continuously in operation. However, once the desired temperature has been achieved, it operates at minimum power merely to maintain that temperature Power Consumption When the compressor is in operation it always runs at 100% of its … Click here to continue…..

Working of Inverter AC

Inverter AC are equipped with a rectifier that converts the incoming alternating current into a direct current. The direct current is routed to a modulator that converts the direct current back into alternating current of the required frequency. The converted alternating current is supplied to a variable frequency drive that supplies power to the electro-motor that runs the compressor. The frequency of the converted alternating current and the frequency of the drive are directly proportional to each other. When the frequency supplied is high, the drive supplies higher power to the motor of the compressor resulting in increased speed of … Click here to continue…..

Working of Conventional AC

Conventional AC have compressors that work at a fixed speed or not at all. The compressor will work at its maximum output – 100% of its capacity whenever it is on, or it will remain idle. The compressor is either on or off. The speed of these compressor cannot be regulated. When the room temperature is 30 degrees Celsius and the thermostat has been set at 25 degrees Celsius, the compressor will keep working to cool down the room, until the temperature in the room reaches the level set on the thermostat. At that point, it will switch off. When … Click here to continue…..
