Ice Rink Dehumidification and Ventilation

Case Study

Ice rink dehumidification and ventilation




At design engineering of air handling system of ice rink Vympel in Korolev (Russia) the project engineers faced a problem of necessary air parameters provision in ice court zone (7-12ºC,
40-50% RH). It turned out to be very cash-consuming and technically groundless to provide these parameters by the method of humidity condensation. It is also not realistic to achieve so low
humidity at such temperatures by condensation.



Finally, together with engineers of DT Group, there was made a decision to use desiccant dehumidification method as the only right way out of a situation. Furthermore after the project on ventilation was revised, the decision to combine ventilation and dehumidification in one unit was made. As result special air handling unit with desiccant dehumidification named DA-10000 appeared, consisting the functions of heating, cooling, drying and adjusting return air mixing ratio. For electricity saving the combined reactivation of an desiccant rotor was implemented (water heating to 60ºC and electric heating to 90-100ºC).

This installation simultaneously provides maintaining of required humidity in a zone of ice rink and also the CO2 level. The installation is fully autonomous. It is factory equipped with controls system with all necessary field sensors, dampers, actuators, valves, and so on. This project has started successfully and provides excellent quality of ice and comfort.

Distinguishing features of the installation

  1. Provides excellent comfort and quality of the ice;

  2. Air handling unit with inbuilt desiccant dehumidifier (2 in 1);

  3. Combined (water + electricity) regeneration for operation cost saving;

  4. CO2 level control.

How does the desiccant dehumidifier work?

The air which should be dehumidified (process air) goes through the desiccant rotor. Water molecules are adsorbed in a special silicagel rotor. Desiccant rotor is regenerated by the second air stream preheated to 90-140 °C. Moisture is removed from the premises in the form of warm moist air.
