Sustainable Mining and Metallurgy

The frequency conversion cabinet emits a large amount of heat during operation, which needs to be dissipated in time to avoid affecting the normal operation of the cabinet. Taking frequency conversion cabinet rooms in three lead smelters with similar configurations as examples, this article introduced different ventilation and air conditioning design schemes that suit different outdoor ambient temperatures. These three smelters are located in severe cold zone C, cold zone B and hot summer and warm winter zone respectively. By summarizing the ventilation and air conditioning measures that suit different outdoor environments, the article provided a reference for the ventilation and air conditioning design of frequency conversion cabinet rooms to be more reasonable and energy-efficient.
