Roof Top 2009-04

On the roof is the swamp cooler.  It so much cheaper to than a regular compressor type air conditioner.  As long the humidity is low (like below 10%) it is effective... even with temperatures at 115 it cools to 83° or so inside.

The swamp cooler is easy to repair and service, but I don't get on the roof.  So I had Gregg go up take a bunch of pictures to show me what's inside.  While he was there he also took a series of "view" shots.

There is a lot of mineral stuff in the "core" where the evaporation takes place.

Both Gregg & I were shocked to see this big 8-inch thick cardboard-like honeycomb evaporation core.  We were expecting something more like 1-inch think furnace filter stuff we'd seen at Lowe's and Home Depot.

It is odd that all the mineral deposits are in one section... the water flows all over it.

Motor, pulley, belt and squirrel cage blower.

One of the pulleys was squeaking a few months ago.  The home owners repair policy paid for the technicians to come and repair that and put on a new belt.

Pumps, tubes, drains and stuff.  The pump recirculates the water.  But several times a day it drains it out and starts fresh.

I didn't go on the roof.  So Gregg took all these pix to show me what's inside the box.

The float valve.  Similar to inside the toilet tank or the automatic pool filler.

Interesting... (not!)

Electrical wires.

It looks like a radiator in a car.  Water is pumped up through the tube and distributed over the top of the core. The water drips down, evaporates and causes cooling.

A nice view of the neighbors back yard,

The core is exposed!
2009-04-26_RoofTop116.JPG
This piece of blue plastic material, sort of like a heavy duty furnace filter, rests on top of the core.  Gregg and I had seen this stuff for sale at Home Depot and thought that was media where the evaporation took place.

The white PVC pipe has holes in it to distribute water the entire width of the core.
2009-04-26_RoofTop118.JPG
The core is 8 inches thick.

Why write down measurements on a piece of paper when you can publish on the internet.
2009-04-26_RoofTop120.JPG
The core is in several sections.  Each section is 8-inches thick & 29 inches high.

Gregg knocked off a lot of the mineral deposit.

While up on the roof Gregg took the opportunity to get a series of shots showing the view from up there.  Here is one of the trees he pruned yesterday.
2009-04-26_RoofTop128.JPG
OK.  Let's start over.  All "normal" maps have north on top.  So let's start by looking to the north.

Looking to the north by northwest.
2009-04-26_RoofTop130.JPG
Northwest.  Mount San Gorgonio way off in the dust and haze.
2009-04-26_RoofTop131.JPG
Looking west and the vacant lot across the street.  Mount San Jacinto.
2009-04-26_RoofTop132.JPG
Look west by southwest. You can see my mutant ocotillo plant which refuses to bloom and the tallest of our "short" palm trees.  In a year or two it will be too tall for Gregg to prune using a ladder and we'll have to have done by the professionals. Or take it down.  This tree is right in the wires.

Looking south by southwest.

Looking northeast... hey who is that naked guy?

Looking north again.

Solar panels.  We hose them off routinely but were advised not to brush or wash them with cleaning solutions.  But they sure look dirty!

Now back to work on the swamp cooler.
2009-04-26_RoofTop142.JPG
More measuring...
2009-04-26_RoofTop143.JPG
So that is 8 inches thick, 29 inches high, 41 inches wide.
2009-04-26_RoofTop144.JPG
Upside down now...
2009-04-26_RoofTop145.JPG
I'm not sure what this is... must be a close up of the spot where the missing piece of core goes.
2009-04-26_RoofTop146.JPG
Notice how the core slopes down to inside, so water drips back into the pan.
2009-04-26_RoofTop147.JPG
It isn't really missing, just out of place.
