   May 26, 2008: AC Modifications for use of AC's in a horizontal/flat mode

  [1] To make the AC work when mounted in the base

  • the heat generated of the 'hot side' of the AC needs to be extracted for the cold side of the AC to get cold. More powerful fans that 'as supplied are needed on the hot side of the AC units in addition to ducting and other fans to aid in the removal of the heated air from the underside of the cabinet.
  • the AC units need to be sealed to prevent condensation to leak thru to the underside

The photos below show how a variety of HOT SIDE  fans are evaluated/tested/compared

Here is the 'test platform' for evaluating the 'original fan' [TONGDA] to 2 more powerful alternatives SOFASCO being most powerful and NMB in between OEM fan and SOFASCO Fan

 

Combined testing of BOTH Airflow and Sound levels


 

Testing SOLELY of Sound level

   

Testing SOLELY of Airflow

   

  •  

The photos below show how each AC unit is modified/sealed for horizontal use and specially sealed for use in a 'horizontal/flat position due to condensate.

 

Areas in need of sealing:

    

 

Initial disassembling of AC unit Hot and Cold sides to access machined holes that needed to be sealed internally.

  

      

    

          

   

June 7, 2008: Mounting the AC assemblies into the base begins: The underside of the cabinet is trimed to allow as much space as possible for all the AC units...4 AC units for each cabinet

   

June 8, 2009: the permanent 'framework' to hold the all the AC has been made and the duct work for bringing in fresh air has been started.

   

June 9 2008: Devised a 'easy access' way of removing and individual AC unit if service is required and redesigned 'fresh air intake' ducting so as to allow for a larger Humidifier

   

June 12, 2008: Underside of AC area and ductwork insulated and tested to insure that cool air reaches AC where it is essential; Humidifier is made and fitted into its own drawer in the base of the cabinet

   

June 13, 2008: Initial 'dry fit' to insure the base and upper align as designed; also shown is the 'final' AC mounting [more simplified/functional and less 'bulky'

 

July 2, 2007:

Condensate collection fabricated and installed

         

Test of Temperature and Humidity variance from top to middle to bottom: 3 separate controllers [all calibrated to match each other] used

 

The internal set up:                                               The external set up

                                

Cooling Test: Room was at 76 degrees; Cabinet set to 65 degrees
 

After 5 minutes  After 10 minutesAfter 15 minutes   After 20 minutes After 25 minutesAfter 30 minutesAfter 35 minutesAfter 40 minutes
 

Humidity Variance test: Humidor run overnight at 70% RH

July 6, 2008: Views of insulation, cover for internal wiring and relays, and new Humidifier drawer face

           

July 8, 2008: Trim installed and cabinets being prepared for lacquering!

                                

July 15, 2008: Lacquered, ready for final 'rub down' and reassembly...

      

       

July 16, 2008: re-assembly in progress:
