I was not personally involved with the particular project, but many years ago I know of a solar based airconditioning system bases on a large Yazaki absorption chiller, and a whole series of concentrated tracking vacuum tube solar collectors. It was a rather large and expensive system by most standards.That IS what I am looking for, something for home use. I want to use solar heat to power it. Ultimately I would like to see a system that would use a Sterling engine to do the pumping of the weak and strong lithium solutions.
https://www.roburcorp.com/chillers/gas_absorption_chiller_ga_acfHello! I am new to the page. I am close to Houston TX. I have several ideas that have came together over the years. I would appreciate any thoughts on them. This all started with the high cost of cooling and an article I read about a man in California that had dual electricity rates, day and night. He froze water at night and used the cool water to cool the house. Recently I have been curious about absorption cooling. I also like the Lister Diesel to make power because hey are really efficient and dependable. I was wandering if I could use the waste exhaust heat from a generator to drive a small, maybe 10 ton Absorption system to freeze water. I would like to run a few hours a day to provide the cooling needed. From what I have read it takes about 20,000 BTUH to drive the absorption systems. Seafarer12 mentioned a solar array to heat water, or is it preheat water. I am wondering what the temperature is of the water is coming out of the absorption system headed to the solar array. There also has to be a cooling system, like a cooling tower. How much heat does it have to handle, reject? I assume the heat from the cooling and the heat used to power the chiller. So, for the 10 ton unit, would that be 200,000 BTUH used to drive it and the 120,000 BTUH of cooling?
Seafarer12, you mentioned a Solar Array as the best way to offset the power requirements in the system y'all have where you are. I have resisted Solar because I thought it was only effective for about 4 hours a day if you have good sunlight. I am fairly close to the Gulf of Mexico and we have a fair amount of cloudy days. I guess I could start with a panel and see how it performs. I am rural so power outages is a concern too. I have a generator for outages now but fuel is expensive. I set the generator up in the attached garage and fabricated an exhaust to run outside. I installed an exhaust fan to pull heat and fumes outside. I still do not care to run a generator while everyone is asleep. So I have two small banks of batteries tied to two APC UPS. One runs my TV systems DSL and all and the other will run my Lighting. I have converted over to LED's except for two Florescent lights for that to work. I do not want to be off grid but would like to be able to supplement my high power usage and be able to run for a few weeks when the power fails. The UPS help too because we will loose power for a second or so and that reboots everything and they prevent surges. I have thought about wind turbine but I am in Pine wooded area. Before thinking about this I was thinking about a Ground Source Heat Pump. Likely though the money would be better used to upgrade insulation and all instead of the absorption system. I also wandered about running a belt driven AC system. A lot of times I think wrong, I get to beating my head against the tree and can't see the forest so any thoughts would be greatly appreciated. Thank y'all! Joe
