The refrigeration section can operate in the following modes:
1. «COLD ACCUMULATION»
The temperature on the surface of the evaporator gradually drops to the setpoint «-700С».
When the setpoint temperature is reaches (-700С), the unit automatically switches to cyclic operation mode in the preset temperature range, with occasional stops of components.
3. «EVAPORATOR DEFROST»
When a certain amount of moisture is frozen on the evaporator, it should be defrosted. The process takes approximately thirty minutes.
Since the evaporator cools in the cold trap to -70оС, a difference in vapor pressure over the surface of solid insulation and in the trap. (E.g. saturated water vapor pressure at + 20 оС is 2337 Pa, and 18 Pa at – 40 оС). This difference drives the drying process. Water vapor from transformer tank move to the cold trap due to pressure difference and are frozen in the evaporator. Duration of drying depends on the amount of moisture in the transformer, its temperature, ambient temperature and residual pressure in the transformer tank. The unit can operate continuously for 20 days.
In the side of the insulated cold trap there is a sight glass, which ensures visual observation of freezing process. The lower part of the trap is equipped with a condensate drain vlave to remove condensate after defrost. On average the unit can trap at least 7.5 kg of moisture in 24 hours.
