Ok HVAC engineers here is a good one. I am pretty familiar with the basics physics of a air conditioner. I had a novel idea for my dual hose air conditioner to greatly increase the effeciency of the unit. This may not work in extremly high temperature and humidity but I live in Utah and it only gets hot, not humid. I want to hook up a 4" inline duct fan to incease the flow along the condenser hopefully cooling them off more than the unit can do itself. I am thinking that pushing air into the intake hose should be better than pulling air from the exhaust. Tell me what you think. I cannot forsee any problems with the portable ac unit and an inline fan uses very little power.
This may be a cheap 15 dollar way to make the portable ac unit work as effeciently as a window one and since the fan will be outside there should be little increase the the noise.
