Re: r410 low ref effect
r410a is twice the operating pressure of r22
discharge pressure is typically 33 bar- at 20deg ambient so at 50 deg ambient, high head pressure and poor performance

To the optimist, the glass is half full. To the pessimist, the glass is half empty.

Re: r410 low ref effect
They are too weak for the present load. Check their specifications for the efficency at such ambient temperature. In all, if the choice of the units was based on a claimed efficiency ratio, then the mistake is now tangible.

So, at first check the "papers," as Mikeref said.
