Numerical Simulation and Analysis of Thermal Environment in Air-Conditioning Office Building

Abstract

The Airpak software is used to simulate the thermal environment in the office of three air supply angles (0°, 45°and 60°) of cabinet air conditioner in summer. Through analysis of the simulation results about the velocity distribution and the temperature distribution in the indoor air flow under three operating conditions, it is found that the thermal comfort of the room is the best in the case of the upward air supply of 45° angle. The optimization of air conditioners should not only consider thermal comfort, but also reduce energy consumption of air conditioners to achieve building energy efficiency.
