A device designed to cool enclosed spaces, typically residential rooms, by circulating refrigerant and expelling warm air to the exterior. It’s installed within a window frame, providing a relatively simple and cost-effective method of localized cooling. For example, during the summer months, a family might install such a unit to maintain a comfortable temperature in their living room.
These cooling systems offer advantages such as ease of installation compared to central air conditioning, portability allowing relocation between windows or rooms, and targeted cooling which reduces overall energy consumption. Historically, they provided a significant improvement in indoor comfort, especially in regions with hot and humid climates, and continue to be a popular choice for supplemental or localized cooling.
