THE 2-MINUTE RULE FOR PORTABLE AIR COOLER

An air conditioner takes in warm air from across the home (or outside the house) and passes it around coils crammed with coolant. The coils extract heat within the air, then blow this cooler air again to the space. An AC unit exhausts its heat out the again from the product (window units) or by way of a air flow tube (portable air conditioners).Err
