Not the best to look at though.

That particular unit you linked (which may be different than your friend’s) has horrendous performance numbers listed. Data below from ad shows a cooling capacity of +/- 7,900 BTU/hr and requires +/- 900 Watts of power. The EER is less than 9.

There is nothing INHERENTLY more efficient about separating the compressor and condenser from the evaporator. It is a packaging benefit that doesn’t make A/C more efficient. The same results can be achieved with other arrangements as long as the same level of technology is utilized.

Chinese companies have a bad reputation for overstating air conditioner performance, and in this case the price is so low compared to equivalent European truck parking coolers that I would be hesitant even if stated performance was much better. Also, the warranty is a joke.

When inverter technology is applied to window air conditioners, as an example, 8,000 BTU/hour A/C from major manufacturers have CEER of over 15. That’s the direction we need in technology whether packaged to mount on roof or elsewhere. And best of all cost is becoming much more affordable due to mass production volumes; suggesting components are cheaper too.
