Hi, all

After running a simulation, I got these errors. Can anyone explain to me? Many thanks

   ** Warning ** Coil:Cooling:DX:SingleSpeed "DATACENTER UNITARY COOLING COIL" - Full load outlet air dry-bulb temperature < 2C. This indicates the possibility of coil frost/freeze. Outlet temperature = 1.97 C.
   **   ~~~   **  ...Occurrence info = OS:RUNPERIOD 1, 04/06 06:30 - 06:45
   **   ~~~   ** ... Possible reasons for low outlet air dry-bulb temperatures are: This DX coil
   **   ~~~   **    1) may have a low inlet air dry-bulb temperature. Inlet air temperature = 15.103 C.
   **   ~~~   **    2) may have a low air flow rate per watt of cooling capacity. Check inputs.
   **   ~~~   **    3) is used as part of a HX assisted cooling coil which uses a high sensible effectiveness. Check inputs.
