[EnergyPlus_Support] coil error / node connection errors

[Dora Chi 纪曉君 <dochido@xxxxxxxxx>]

  I keep getting severe warnings and cannot seem to figure out where the error occurs.  Your help is greatly appreciated, the model is attached.

(1) 
 ** Severe  ** For object = Coil:Cooling:DX:SingleSpeed, name = "VRV-B1500_COOLC DXCOIL", the combination of
   **   ~~~   ** rated air volume flow rate, total cooling capacity and sensible heat ratio yields coil exiting
   **   ~~~   ** air conditions above the saturation curve. Possible fixes are to reduce the rated total cooling
   **   ~~~   ** capacity, increase the rated air volume flow rate, or reduce the rated sensible heat ratio for this coil.
   **   ~~~   ** If autosizing, it is recommended that all three of these values be autosized.
   **   ~~~   **  During Warmup, Environment=BEIJING ANN HTG 99.6% CONDNS DB, at Simulation time=01/21 00:00 - 00:05

(2) Severe Node Connection Errors - I cannot find the missing node or what needs to be altered in the model.
