Phase change cooling system for a rack-mount servers(final installation)

The task was to make the server rack completely dustproof and with zero intervention in the work.
I had to add thermal insulation to prevent dew on the surface of the rack.
Plus, a system for removing and ultrasonic evaporation of moisture into the exhaust ventilation system, from the inside of the rack,
which could be there from the air that was locked.
The system in idle mode, consumes about 1.5 kW of electricity, while inside the rack,
a stable temperature of about -20 centigrade (in the summer about -17 centigrade).
The refrigeration compressor is controlled by VFD, which, like everything else, including the fans,
is in turn controlled by a microcontroller.
The condenser of the cooling system, purged with cold street air,
after filtering with car filters.
Warm air enters the surrounding room, from where it is quite efficiently drawn into a passive exhaust ventilation system.
