Heat Heart Chill (March 29th)

As we drove up this week, we could see more of the house had been painted and the house was comfortably ensconced inside the wall.

Take careful note of the paint over the entryway to the right. You'll need this for future refrence.

The inside was appearing less and less perforated as we got more lights and covers over the HVAC vents.

There really is supposed to be an "R" added to the end of that as in HVACR for Heating, Ventalation, Air Conditioning, and Refridgeration but acronyms longer than four letters are just not acceptable in a civilized society.

The refridgeration part is the coolest (That pun is unfortunately unavoidable and absolutely not intentional. But, since it's already out there...) but we just discard it as if to convince ourselves we don't really need it. but, oh my friends and loved ones, we do... we really do...

A quick note:
For some reason I start talking about how Refrigeration works below. If you are not interested in an odd but conceptually accurate explanation of the process, skip to the first picture of someone you recognize.

The whole things works on the second law of thermodynamics which states "Heat hate hot Heat heart chill".

Ok it doesn't really say that but it does say a lot of stuff about entropy and equilibrium in a system and that's all just crazy talk.

Simply put:
Heat pretty much hates other heat. It can't stand to be around itself. It will always try to get away from itself. Forever.

Imagine heat as fussy, cranky, lunatic people with big spikey hair.

Heat is really just looking to get enough space so that nobody messes up its hair. Heat NEEDS it's hair looking good, man.

We'll call this HairSpace and it's constant (this is the entropy equilibrium part).

Heat hates bad hair so much that when given an opportunity, it will gladly leave whatever area it is hanging out in and move into whatever it can touch that has less heat in it. Less crowded, more "hairspace", better hair.

So how do we use this behavior to get cold air in our house? We play mean games with heat. We make heat go on a long trip with all of its family, it's friends, it's friend's family, their friends and their friend's families. We put them in a HUGE triple decker bus. Plenty of "hairspace" on that bus.

Then, when that bus is outside, suddenly, we shrink the bus down to the size of a VW Beetle. Much less "hairspace" now. As you might imagine, Heat starts freaking out. Pouring out of every opening it can find. Screaming about hair and stinky cousins. Heat comes out so fast that if you put your hand near that area, you would feel heat jumping across into your skin.

After a short time, enough heat has left the car so that the heat still inside has calmed down and is pretty much ok with the hair situation. It would still like to go somewhere else if it could find less heat, but the heat outside is about the same as the heat inside the VW Beetle and there really wouldn't be any benefit to going outside.

Then, as the little VW is heading inside, we suddenly make it as big as a triple decker bus again. Check it out!! All kinds of empty seats and room for spikey hair.

For a brief moment, the heat inside the bus is happy. It doesn't need to go anywhere. It doesn't have to worry about it's hairdo. Plenty of space for heat. As a matter of fact, there's more space for heat than the amount of heat on this bus!

Guess what? Heat goes nuts. This bus has WAY less heat in it than the air around it.

Like crazed zombies determined to reach the brains, the heat from inside the house starts pouring into the bus. (We help by blowing a fan over the bus as it goes by so as much heat as possible sees the seats on the bus. When the air passes the bus, the heat in the air jumps off the air and gets on the bus.)

When there is less heat in the air there is space for heat in it. When it touches our skin, our heat jumps off of us and goes into the air. We feel cooler as we warm the air. Hooray for us.

We then take that big busload of heat and drive it outside. Squeeze the heck out of it and start the process all over.

It really looks like this.

In our case the "car/bus" is some non-toxic material like Freon (Which was invented around 1930 specifically to keep people from dying because their refrigerator was leaking. Prior to Freon we used to use ammonia and chlorine gas.)

This is where all the magic shrinking of the bus happens. We have three of these things.

Inside the house we had cabinets. This was good to see, more definition of space. More house-like. The color was good and we have stuff to put in them.

How's that for coincidence?

Guardian had to come and finished the wiring with their various plugs and jacks. I am sure something isn't connected correctly but I won't know until sometime past the 20th of May.

Remember the floor boxes we installed at the beginning of this saga? We had to put the brass covers on these because the tile was coming.

Here you can see all of the necessary tools for attaching brass covers to floorboxes. Pay particular attention to the donuts.

Never forget the donuts.

They also needed to grind down the concrete to make it smooth. There were a few sections that were marked for grinding. It would seem that the guy who grinds concrete uses special flourescent lighting to see where to grind.

Boxes covered, we are very excited for the tile to come in.
