AC380V power supply requirements:
1. Three-phase four-wire + protective ground wire;
2. Voltage range: AC(380±10)V
3. Frequency allowable fluctuation range: (50±0.5)Hz
4. Grounding resistance of protective grounding wire is less than 4Ω
|Maximum current power consumption
Current: (13) A
[Voltage range: no more than (+10%)]
||20%-98% RH (the distribution range is as follows)
1. The control system automatically adjusts the operation of the refrigerator according to the test conditions, so that the equipment is in the best energy-saving condition.
2. The refrigeration capacity of the evaporator is switched by the solenoid valve driven by the control system.
3. Compressor return air cooling circuit.

Rigid polyurethane foam
its advantages are:
1. High efficiency and energy saving, seamless after filling, strong bonding after curing.
2. Seismic and compressive resistance, no cracking, no decay, no falling off after solidification.
3. It has ultra-low temperature heat conductivity, weather resistance and heat preservation.
4. High efficiency insulation, sound insulation, waterproof and moisture-proof after curing.
5. waterproof performance is good, because the foam hole is closed, the sealing rate is 95%, and the rainwater will not permeate through the hole.
