A study on stratified air conditioning cooling load calculation model for a large space building

Abstract

Based on the theory of regional heat and mass balance, a stratified air-conditioning load calculation model suitable for large-space buildings was established. A test of a large-space building under summer conditions was conducted to verify the calculation results of indoor vertical temperature distribution. The stratified air-conditioning cooling load calculated by the model was compared with the actual air-conditioning cooling capacity. The calculation results showed that the difference between the actual air-conditioning cooling load and the model calculation result was 14%. Based on the model, the vertical temperature distribution under variable operating conditions was predicted.
