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 ai… Show more

“…Generally, the air inlet should be located at an appropriate height in the non-air-conditioned area, and the temperature of the air inlet should be lower than the air temperature at the same height in the non-air-conditioned area. The lowest position of the air inlet should be 1/3 of the height of the non-air-conditioned area [32]. In this paper, the natural ventilation inlet is selected at 14 m.…”

“…These aspects are crucial with significant impact on student/teacher wellbeing, productivity, health safety, and performance but also on the national healthcare system. Therefore, in the present context of the post-COVID-19 era many recent studies have investigated plant systems adaptation and energy efficiency interventions [5][6][7][8]. Much literature has analysed some crucial questions: mechanical ventilation systems efficiency and efficacy, natural ventilation effect connected to physical distancing, CO2 and occupancy monitoring, protection and prevention measures for people health and contamination risk reduction [9][10][11][12].…”

“…In particular, some authors have demonstrated that demand controlled ventilation combined with an HVAC variable air volume system, both in school and office buildings, can guarantee significant energy consumption reduction with high indoor air quality and effective ventilation [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. The CIBSE document concerning COVID-19 air cleaning technologies, has foregrounded how scientific evidence suggests solutions with air purifiers to minimize the risk of contamination and infection only in specific situations.…”
