Variable speed refers to the fan motor inside the the indoor part of an air conditioner that moves cooled or heated air throughout the ductwork of your home.

Variable frequency air conditioner.

Variable speed compressors work differently. Variable speed air conditioners work more like the gas pedal in your car letting the ac adjust to the needs of your home. Basics of variable speed air conditioning.

This way the ac can run at a low setting most of the summer saving you serious money. As a result they run for much longer cycles than single stage ac units. A variable frequency drive vfd is an electronic system that provides infinitely variable speed control of three phase ac induction motors. P the number of poles in the motor.

The heart of an air conditioner is the compressor. It is a significant step in china energy saving campaign to apply the frequency conversion technology into the central air conditioning system. Unlike conventional single speed motors a variable speed motor runs at a wide range of speeds to precisely control of heated and cooled air throughout the home. Controlling the flow of air and water in hvac systems is an effective permanent way to meet the ever changing demands put on the system.

V the frequency of the current in hertz. The research projects that the variable frequency air conditioner market size will grow from in 2018 to by 2024 at an estimated cagr of xx. An air handler is usually a furnace or a blower coil. In order to maintain an indoor temperature that matches the setting on your thermostat they operate continuously at less than 100 capacity often as low as 25 or 30 capacity.

In terms of air conditioner units an inverter is used to control the power supply frequency of the compressor motor to adjust the cooling heating capacity of the unit. Variable frequency air conditioner market overview. When a variable speed system starts the vfd outputs ac voltage at a low frequency to the controlled motor. How variable speed air conditioners work.
