So hot and muggy this evening. I work outside for 15 minutes and cool off and enjoy another cup of water for 15 minutes, repeat. Maintaining the garden is hard work.
I repaired the air conditioner in my car this afternoon in the blazing heat. Finding the problem required hooking the computer to the car. The diagnostics showed no communications with the air compressor. That's right, the compressor has a CPU and a high voltage motor inverter inside.
The connector looked good, so I did the other wiring troubleshooting trick of pulling the wires if there's one broken. And yes, I found two broken communication wires. I soldered and heat shrink sealed them, reinstalled everything, vacuumed the system for an hour, then charged the specified refrigerant.
And the air was cold. All electric and quiet. The computer in the car was amazing, showing the evaporator had two temperature sensors, one for the refrigerant inside the evaporator and one on the fins. The expanding refrigerant temperature was computer set at freezing and the fin temperature was a few degrees above that to prevent ice accumulation. It showed the compressor running at 5000 rpm and over two kilowatts. There were dozens of other sensors displayed too. I was a total nerd and reading them all while adjusting the temperature.
The sun has set and the house battery is now charging the yard tool batteries. I plan on setting up a hammock on the porch and lay in front of the fan. The playful raccoons and opossums should be out to join me again tonight. They love finishing off what's left of the bird food I left on the ground. The nocturnal animals are amazing and friendly. Even the skunks. Fireflies and glow bugs are out too. Feels delightful to be alive off grid and away🌌
