The open setting brings in the air from the outside. The closed setting brings in air from the room. With most air conditioners, you don't have to use the cooling function - you can use it just a fan. So if you don't have the cooling function on, you can bring in air from the outside, just like a fan does.
Furthermore, how does a room AC work?
The basic components inside the unit include a blower and/or fans for moving cooled air into the room and exhausting warm air, and refrigerant components for extracting heat from the air. Those components include a compressor, evaporator coil, refrigerant-filled tubing, and condenser coil.
How does a central air conditioner work?
With a “package system,” all of the components are combined in a single outdoor unit that may be located on the ground or on the roof. A central air conditioner cools with an outdoor compressor and condenser coil connected to an indoor furnace fitted with an evaporator coil.
What are the parts of an air conditioner?
Still, the major parts of an air conditioner manage refrigerant and move air in two directions: indoors and outside:
- Evaporator - Receives the liquid refrigerant.
- Condenser - Facilitates heat transfer.
- Expansion valve - regulates refrigerant flow into the evaporator.
- Compressor - A pump that pressurizes refrigerant.
