What does a DC inverter mean?
INVERTER technology delivers precise cooling or heating power as per your choice.

It works faster and saves energy while ensuring uniform temperature.

In Depth details:

The inverter tag found on some air conditioners signifies the ability of the unit to continuously regulate its thermal power flow.

Traditional reverse-cycle air-conditioners use a heat pump that is either working at maximum capability or switched off, as the compressor's speed cannot be varied. In order to regulate temperature a thermistor is used to measure the ambient air temperature and switch the compressor on when the ambient air temperature is too far from the desired temperature.

Air-conditioners bearing the inverter tag use a variable-frequency drive to control the speed of the motor and thus the compressor. The variable-frequency drive uses a rectifier to convert the incoming AC current to DC and then uses pulse-width modulation of the DC current within an inverter to produce AC current of a desired frequency. The AC current is used to drive a brushless motor or an induction motor. As the speed of a brushless motor is synchronised to the frequency of the AC current, it is thus possible to build a compressor that can be run at different speeds. Similarly, the voltage and frequency can be varied as needed to efficiently run an induction motor at different speeds. A microcontroller can then sample the current ambient air temperature and adjust the speed of the compressor appropriately.

Eliminating stop-start cycles increases efficiency, extends the life of components, and helps eliminate sharp fluctuations in the load the air-conditioner places on the power supply.

What are central air conditioners?
The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.

Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.

Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.

The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.

Central air conditioning can also be provided through a package unit or a heat pump.

Does my air conditioner have a dehumidifier?
Yes, if you buy the advanced units (SEER 15 or higher with inverter technology), they normally come with independent dehumidification modes. Standard units will dehumidify as well, but only when AC mode is running. With advanced systems, you can simply put it on dehumidification mode without having to turn air conditioner on.
