This article gives an overview of the operation of dehumidification plants located in indoor ice arenas. Since at the moment the operation of such facilities does not include control of such parameters as CO2 content, the possibility of implementing this task using the existing equipment is considered. A method of setting the automatics of maintaining the CO2 level in the set parameters is given. The principle of dehumidifier operation and problems of CO2 level control are considered. The method of tuning the control loops is also described. The use of CO2 controlled dehumidifier equipment will create comfortable conditions for the occupants of the ice arena, which in turn will lead to a reduction in energy and heat consumption.
