I have read most of this thread, and it seems the manufacturer has mixed up Adsorption concept with absorption, according to my early studies from high school. Now this comunity is all proffesionals, so am not adding any thing by way of fundamentals and theorums. My note is, would it be benefficial to connect the solar heat concentrator array on the suction pipe before the compressor inlet port? Could that give the needed boost and really help the compressor do its thing? Since the gas at that stage would be at a raised pressure already from the heat input.
My opinion is to just cool the gas out of the condeser by routing the high pressure liquid through a final 4 loop coil, running in a plastic container seated in the outdoor unit; filled with water from the condensate line to help the compressor when the weather is above 40 deg celcius.
At least it has droped the electrical current rate for the 24000 BTU heatpump/AC unit that I have at home, even the compressor worked quiter when I water cooled last few lines of the condenser coil.
Perhaps installing a swamp cooler adjecent to the outdoor unit would suffice to give a real overall saving by way of cool moist air helping condense the refrigerant gas.
