Key to remember....

Air conditioning is the REMOVAL of heat. . .;
You never have a 20' indoor air temp, so I think if you covered your a/c unit it would build up the pressure and add to the heat inside.
Heat pumps were designed by Canadians, as are good ice machine , go figure. I think the real question is will it produce more heat on a warm day (or covered box) answer is ......... it will only produce what has been installed at start-up, meaning it's all designed on refridgerant pressures. I have a 3 ton 14 seer unit on my house and it seems to run to much for my liken,but it's pretty good heat source in Georgia. You need a coil temp at least 20' above room temp wanted. so, you want 70 rm temp, coil temp needs to be reaching 90..
