Analysis of indoor thermal comfort of different air-conditioning systems

Abstract

Taking a typical two-person office as the research object, the indoor thermal comfort of the radiant cooling-displacement ventilation air-conditioning, the radiant cooling-personalized air-supply air-conditioning, and the all-air air-conditioning were simulated and studied, and the indoor thermal comfort index properties was analyzed. It was found that the indoor personnel activity area with radiant cooling-personalized air-conditioning had the lowest air supply temperature, PMV and PPD, and the air supply speed met the requirements. The thermal comfort effect of the human body is significantly better than that of the other two air-conditioning, which provides a reference for the design, promotion and application of the new air-conditioning of radiant cooling and personalized air supply combined cooling in actual projects.
