1. Fan is suitable for the temperature in the cabinet higher than the ambient temperature, but when the internal and external circulation in the closed environment requires isolation, industrial air conditioner should also be considered.
2. The air conditioner adopts the compressor refrigeration principle for strong refrigeration to realize the constant temperature control of the internal temperature of the electrical control cabinet. Because the air circulation inside and outside the electrical control cabinet is isolated from each other, it can effectively prevent harmful and humid gases and dust from entering the cabinet.
According to its installation mode, air conditioning can be generally divided into wall mounted (side mounted, embedded and cabinet mounted) and top mounted. The selection of air conditioning is also based on the difference between the cabinet temperature and the ambient temperature and the heat loss in the cabinet, so as to determine the cooling capacity required by the air conditioning.
