An air cooler is a device that circulates air and cools it before releasing it back into the environment. Its effects include:
Cooling: The air cooler can reduce indoor temperature by circulating cold air, providing a comfortable environment.
Ventilation: Air coolers can help with air circulation, reduce indoor humidity and odors.
Energy saving: Compared to air conditioning, air coolers are usually able to achieve cooling effects with lower energy consumption.
Environmental protection: Using air coolers can reduce the impact on the ozone layer and the environment, making it a relatively environmentally friendly cooling method.
