How Ductless Air Conditioning Works

Traditional air conditioning systems need ductwork to deliver cool air. In an effort to help cool ductless commercial spaces, ductless air conditioning was developed. This innovation has now moved into residential spaces, offering non-ducted homes the possibility of having manageable, efficient, whole-home air conditioning during the summer months. So how exactly does ductless air conditioning work? Here’s an overview from our Jacksonville ductless air conditioning experts at Touchstone Heating and Air, Inc.

The Components

A ductless system operates with 4 main components:

  • Condenser and compressor unit
  • Evaporator coils
  • Refrigerant lines
  • Conduit connecting the in-and outdoor parts

How It Works

The condenser and compressor are housed in an outdoor unit, very similar to that of a standard split-system air conditioner, and it functions in almost the same way, delivering refrigerant to the indoor air blower. Each ductless system has at least one indoor air blower, if not several, to which the outdoor unit is attached.

The evaporator coils are housed in the inside blower unit, along with a fan and the system’s air filter. In a standard split-system air conditioner, the evaporator unit is also indoors, but is usually larger and part of the heating system. This is one of the main differences between a ducted system and a ductless one.

The indoor blowers and outdoor unit are connected via a conduit placed between them through an exterior wall. This conduit holds a power cable, refrigerant line, suction tubing and a condensate drain. The indoor blowers are mounted and then connected to the outdoor unit.

Each blower is programmable. When the temperature in a room becomes higher than the temperature set on the blower, the system turns on: the outside compressor is activated and refrigerant begins to circulate. The refrigerant passes through the compressor, releases its heat through the condenser and then flows to the indoor air blower where it begins to circulate through the evaporator coils. The fan of the indoor blower turns on, blows over the evaporator coils and sends cool air into the room. While it seems that these units simply blow cool air into the space, what they actually do is remove the heat and humidity from the room, run it through the system, and bring it back into the room as cool dry air.
