When the air conditioner works, the refrigerant in the evaporator exchanges heat with the secondary refrigerant, and the refrigerant in the condenser exchanges heat with cooling water or outdoor air.
When the unit is shut down in winter, it is often necessary to drain the evaporator to prevent the coolant in the evaporator from freezing and damaging the evaporator. However, when the unit is started again, it takes a certain time to supply water again, and since the ambient temperature is low, the oil temperature of the lubricating oil in the compressor is also low, and it takes a long time for the oil temperature to rise to the normal temperature after the unit is started, all of which will result in that the cold water air conditioning unit cannot be started and operated quickly in winter.
