Thermal Comfort Characteristics Analysis of Induced Radiation Units

Abstract:

Induces the operating principle of the induced radiation unit and studies the uniformity of indoor temperature distribution in the space and time, comfort and dewing condensation based on the PMV-PPD thermal comfort evaluation system. Through data collation and results analysis, obtains thermal comfort superiority and energy-saving potential of the reduced radiation air conditioning. The results show that the temperature distribution in the room stalled by the reduced radiation units is uniform, without sense of temperature difference and ventilation, providing an ultra-comfortable environment and that the indoor setting temperature can be up to 27°C on the premise of meeting comfort requirement. At the same time, air supply of low temperature can be achieved without condensation, reflecting the energy-saving potential of the system. These provide a reference for design of the induced radiation air conditioning system and further study.
