Ductless air conditioners consist of two different but interconnected units.  One unit mounts in the space being cooled while another unit mounts outside, usually on a concrete pad or on a rooftop.

The outside unit comprises the compressor, condenser, and a fan to draw air across the condenser. The inside unit comprises the evaporator core and a fan to circulate air. To get more information you can search for ducted air conditioning via https://www.carrierair.com.au/ducted-air-conditioners/.

The inside and outside units are interconnected with tubing to take the refrigerant. The liquid refrigerant is provided to the interior evaporator unit from the outside unit. Then the liquid refrigerant is metered to the evaporator by way of an expansion valve.

Since the refrigerant absorbs heat from the space being cooled through the evaporator, it then returns to the external unit throughout the return tube. The tubes are often refrigeration grade copper but other kinds of tubing are occasionally utilized depending on the conditions.

Additionally, between the inside and outside components, a controller cable is usually run. The control cable enables the thermostat to the indoor unit to also trigger the compressor as required. When the temperature within the space being cooled raises above the setpoint, the components switch on.

In conclusion, ductless air conditioning is often chosen as an economical method for residential, commercial, and even industrial uses. The price of operation is reduced to cool only the space that has to be cooled rather than air conditioning the entire structure.
