Gentlemen,
I live in the tropics (Puerto Vallarta), and have a very keen desire to power a refrigeration system from gas. I always assumed it would be some sort of ammonia refrigeration system, or a super-big version of an RV fridge. Currently, I build charcoal retorts and charcoal gasifiers. Just haven't had time to dive into the refrigeration sciences yet. Additionally, there may be a way to use "waste heat" from a retort vs. direct flame. I just don't have the numbers yet, but am very interested in this thread. Thank you guys!

This is a good start.

I think it has been an issue which has unfortunately deserved little attention, when compared to power and heat production. In order to answer your question, I am sending my preliminary estimates on the practical refrigeration capacity you are asking for. 1. Assuming 2.5 tpd of biomass to be gasified, it should deliver roughly 240 m3/h of producer gas. 2. Considering a COP value of 0.6 for the chiller. 3. LHV of the gas of 5000 kJ/m3. My modest estimates of the refrigeration capacity should be around 200 kW. I hope those figures could be of help to you. Kindest regards. Oscar.

Has anyone coupled a small pyrolyzer or gasifier up with a boiler and an absorption chiller? What sizes and capacities make sense? We're looking at a fuel input of 2-3 tpd. How much char can I make and what practical refrigeration capacity can I generate? I am assuming that the chiller can get down to about 36 F (2 C). The cooler the better.
