    Rotolocks

    Dealing with large scrolls, 15 ton. I need to take a poll. Would you prefer sweat or rotolock terminations on the compressor? We presently use rotolocks, manufacturing would rather braze.

    Agree, if your protection level is only 25, you are skating on the edge of freezing in the coax, especially if flows are low. Protect the loop to 15, and get flow rates up, and the system should be...

    When you suspect the air coil, it's good practice to disconnect the fan motor and freeze the coil. You can then see which end tubes are not freezing.

    Yes, we will be controlling the flow through the coax to satisfy a discharge air temp sensor. Not really so difficult. Reheat is inherently not efficient, so the drop in EER can be justified.

    I agree with you, but should I size for the sensible capacity of the DX coil at an entering air condition of 80/67 or at a lower temperature? Thanks for the reply.
