So, here at 5gallonairconditioner.com, we continue to get asked about why I don't insulate the Ice Model air conditioners. So, in this short blog post, I will explain the reasoning and the physics behind that decision. By definition, the purpose of insulation is to "reduce the heat transfer between the outside environment and the inside environment." So, that is exactly the opposite of what we are trying to do with the ice model units. Ok, so here is a quick thermodynamics lesson, in easy to understand language.  First off, you need to think in terms of heat, not cold.  So,...

So here at 5gallonairconditioner.com, I keep getting asked about batteries, and how long they will last etc. So, I will take a little break from the "does it work" series, to battery life, and battery life calculation to answer the "how long" question. When talking about DC powered devices, there are 2 things to remember about "power," namely the quantity and how fast. So, how much power, and how fast is it coming, so to speak. In electricity terms, these are called  AMPS and VOLTS.  Volts describes the how fast, and amps describe how much. Think of electrical current this...

Here is the 4th article in the series, that will help you answer the question, "does it work?" So, the next concept that one needs to understand when it comes to Air Conditioning, or more appropriately, temperature control,I need to describe some concepts called "solar affect" and "greenhouse effect."   So, in the most basic terms, solar affect is the phrase used to describe the heat that is absorbed in certain materials by the sun.  It's why the dashboard of your car is hotter than the outside temperature in the summer, or your vinyl seats are hot on your legs in your car...

This is the 3rd article in the series, where we will once again provide proof and calculations that will help you answer the question "Does it work?" Ok, so this concept is very easy to say, but a bit difficult to think about. A few days ago, I wrote about a BTU and what BTU is a measure of, and why we measure air conditioner capacity in BTUs. So, this short blog post is going to give a little more info, specifically about ICE air conditioners.  I will give the specific scientific definition, and then follow it up with a...

Here at 5 Gallon Air Conditioners Inc., I get asked this question all the time.  Of course it does!!  The only real question is, what do YOU mean by work? This is the first blog in a series of short articles that will answer these questions. I am a chemical engineer and I will try my best to explain the nuances and the physics, in plain language, so that I can educate each of you on this simple yet very complex question. Do you want it to cool down your whole 2000sf house 20 deg F in 10 minutes? In...
