For those in the Southern Hemisphere who planto leave home in your vehicle when the apocalypse hits, consider taking a portable air conditioner with you. If you’re on foot, this would be impractical, since you should know to take shelter in a cave or cluster of trees to stay cool. A portable air conditioner is relatively inexpensive and – as the name implies – easy to transport. Make certain it’s battery-operated, as there probably won’t be any electrical outlets available, but also make certain it doesn’t require water to function. Water is too precious a resource to waste on appliances, unless it’s a water purifier. But, I’ve already covered that topic.
Some portable air conditioners have one hot air exhaust hose, while others have two hoses: one for air intake and one for hot air exhaust.
A single-hose portable air conditioner will take air from the room where it’s located, cool it and then return most of that air back into the room. During this process, a small amount of that air will be used to cool the unit and will be subsequently blown out of the air conditioner’s exhaust hose. This creates slightly negative pressure within the room being cooled, as a small amount of air is constantly being removed from the room. If this negative pressure is anticipated by drawing unconditioned air into the room from adjacent spaces, then the cooling efficiency is slightly affected.
A dual-hose air conditioner pulls in air from outside a structure through one hose and utilizes that air to cool the unit. The hot exhaust air is then expelled through the second hose. This process doesn’t create negative pressure inside the room being cooled. Dual-hose units use warmer, unconditioned air to cool their compressors, which results in slightly less efficiency. They also employ two internal fans, which can mean slightly higher energy usage.
Portable air conditioners use mineral mica to function. Mica is a valuable resource because of its chemical and thermal properties, low power loss factor and that it doesn’t need electricity to operate. Remember, the abrupt shift in the Earth’s axes will render power and utility plants useless, so this particular feature is important. It also means portable air conditioners aren’t prone to cause fires, even in an enclosed environment, such as a car or truck. That will make things easier, as you struggle to search for food, water, chocolate and to keep your kids and pets from wandering away. Air conditioning is one of humanity’s greatest inventions, next to the telephone and dental floss. Therefore, the ability to rest somewhat comfortably in the heat ultimately will give you more strength to fight off any rap singer or celebrity athletes who survive the upheaval.
