Indoor cooling/heating load analysis based on coupled simulation of convection, radiation and HVAC control.

Author(s) : KIM T., KATO S., et al.

Type of article: Article

Summary

The paper presents a computational fluid dynamics (CFD) simulation for analysing indoor cooling/heating load. It is coupled with a radiative heat transfer simulation and heating, ventilating, and air conditioning (HVAC) controlling system in a room. This new method feeds back the outputs of the HVAC system control to the input boundary conditions of the CFD. The method includes a human model to evaluate the thermal environment, which is used to analyse the heating/cooling loads of different HVAC systems under the condition of the same thermal sensation, even though the temperature and air-velocity distribution in the room are different from each other. The reducing effect of cooling load with clothing conditions are evaluated quantitatively.
