"portable air conditioner"的定义和意义

What is a "portable air conditioner"?

A portable air conditioner is a compact, movable device used to cool a room or small space. Unlike traditional air conditioners that are installed in windows or walls, a portable air conditioner can be easily moved from one room to another. It works by removing heat from the air and releasing cool air back into the room. These units typically have a hose that vents warm air outside through a window. Portable air conditioners are ideal for rooms without central air conditioners or where a temporary cooling solution is needed. They are easy to set up and can be moved around as needed.
