A total disaster. It appears the cooling tower part of the package is undersized for the chiller and may have contributed to its early demise. The exhaust gas heat medium is problematic since it is a compressible fluid and turbulent. Steady state is hard to maintain so the unit never made capacity. The materials are terrible. The machine is fairly new and is showing advanced corrosion inside and out.

I believe the point of non-electric, absorption chiller is that it makes better use of the primary state of energy. What ever electricity that comes through our electrical outlet is generated from fossil fuel based energy source. My studies in the environmental science has generalized a principle that distributed energy consumption mode is most energy efficient, because you are more flexible and you cut down the transmission loss. So you are really considering the whole picture. Just by looking at a single unit doesn't make up as much as a difference, but on a national level. <br /><br />Back to the topic of using the primary energy, electricity is generated with only 20% efficiency, so all that waste heat is emitted into our atmosphere. In the case of absorption chillers it uses primary energy and converts to cooling at a much higher efficiency simply because there are less steps of energy conversion, which means less loss. That's just my 2 cents.Daniel Zhanghttps://www.blogger.com/profile/16662472152696886137noreply@blogger.comtag:blogger.com,1999:blog-10329278.post-91156943171080263522008-09-25T14:43:00.000-03:002008-09-25T14:43:00.000-03:00We are involved with a double effect Broad chiller...We are involved with a double effect Broad chiller that has serious problems that seem to be manufacture issues.

Fro...The Yazaki absorber looks like a good product. From what I can find on the internet. It only takes 2 amps to run a solar 5 ton cooling absorber. You'll need an aditional pump to run the chilled water, which would be minimal. If you buy an heating / cooling absorber, the cost would go up significantly. The cooling tower is exspensive to buy and to use. It seems like the financial return would take forever. However you could have solar cooling and then perhaps if you have a swimming pool then it would eliminate the cooling tower. Unfortunately the 80 gpm needed for the cooling tower is alot of volume to match, it depends on the delta P of the water. If I could get the engineering fine tuned. I think I could get the over all running costs for heating and cooling down to 10 amps total and that is a 30% reduction in running costs. The problem is I cannot find a decent distributer that know what he's talking about. I live on the west coast and cannot locate anyone for Yazaki localy. <BR/><BR/>References:<BR/>Solar Panels Plus<BR/>Yazaki Power systemsAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-10329278.post-32180799073695980962008-03-15T13:31:00.000-03:002008-03-15T13:31:00.000-03:00I really do not understand what the fuss about Bro...I really do not understand what the fuss about Broad is all about!<BR/>Absorption HVAC has existed for decades now, so what exactly is new here? The news will be when some manufacturer makes a cost break-thru into affordable 5-tons residential units. If you'd like to make a "green" statement, the technology is here since long ago, be it Absorption gas-fired, Solar powered, Geothermal, etc. The catch is none of this will payback in your lifetime!!!<BR/>What can and does pay is small Hydroelectric turbines which generate "free" electricity from naturally running water stream, then use this electricity for lighting, air conditioning, cooking, hot water, etc., then you can say you're truly green AND economically viable; which is the only way to be green because when you just burn money you're not green at all!!<BR/>PS: I'm a US citizen working in Cairo, Egypt, where we do have Gas-fired HVAC & district cooling for several years now without the fuss of Broad's...Nothing is new!!
