Abstract
The actual purpose of the study was to develop technical solutions for organizing of a panel-radiant cooling system using ceiling devices in a multifunctional building, as well as the calculated justification of its use in comparison with an alternative cooling system: a classic central air conditioning system and a "chiller - fan coil". The comparison was carried out according to the indicators of the microclimate comfort in the serviced room, taking into account the feasibility study. The evaluation method was used to determine the comfort factor of a person's thermal state, taking into account correction coefficients for the main hazards characteristic of multifunctional public buildings. The use of radiant ceiling panel cooling systems increases the comfort of people in the room due to the fact that there are no convective jets with low temperature and high air velocity. At the same time, the most favorable temperature allocation over the height of the room is maintained.
