9. Rotameter for Refrigerant flow measurement.
10. Duct : Air duct of size 250 x 250 make out of

CRC sheet in which evaporator is fitted.

11. Baby Boiler : Electrically fired small baby boiler for

maintaining humidity of air with electrical heater

12. Blower : 1 HP capacity centrifugal blower with air

control arrangement.

CONTROL PANEL :

1. 12 Channel Digital Temperature Indicator
2. HP-LP Cutout : Make Ranco /Danfoss or Equivalent.
