Research on technology of mobile air conditioning room in mines;

Cyclic spray of condensing water not only extends continuing operation period of portable air conditioners(PACs),but also strengthens heat transfer performance of condenser.

Comparing with the horizontal pan vacuum filter,the moving-chamber belt vacuum filter can effectively reduce adsorption of sodium oxide,water consumption and electric power consumption, and can improve the quality of products.

For example,the air make-up ventilator and the fresh air handling unit share the fresh air inlet,the extract system and smoke control system share the air-exhaust ventilator,the bathroom air-conditioning uses the in-the-ceiling type air handling unit(ch.
