Analysis of Condensation and Thermal Comfort of Two Kinds of Compound Radiant Cooling Air Conditioning Systems Based on Displacement Ventilation

The working principle of radiant cooling and characteristics of displacement ventilation are introduced in this paper, the essence of dew and the method to solve condensation are also analyzed in this paper. The research progress about condensation of the attached with a jet under the action of the floor radiant cooling with displacement ventilation system and evaporation cooling of floor radiant cooling with displacement ventilation system are summarized in this paper, analyzing the thermal comfort of the room using the two kinds of compound radiant cooling air conditioning system by contrast. The results show that the attached with a jet under the action of the roof radiant cooling with displacement ventilation air conditioning system prevent condensation is better than the former; Indoor air quality of attached with a jet under the action of the roof radiant cooling with displacement ventilation air conditioning system of is better than that of evaporation cooling of floor radiant cooling with displacement ventilation air conditioning system.
