Analysis on influencing factors of hourly cooling load coefficient in an airport terminal in summer

Investigates the influencing factors of the hourly cooling load coefficient in an airport terminal in summer. The results show that both intermittent added cooling load and hot air intrusion cooling load are the main factors affecting the cooling load coefficient of the terminal. The intermittent added cooling load only occurs within seven hours of the initial operation of the system, with an hourly maximum value accounting for 15.9% of the basic cooling load. The intermittent added cooling load gradually decreases with the air conditioning system running, and does not coincide with the maximum value of the building cooling load. Therefore, this factor does not increase the design value of the cooling load. The hot air intrusion cooling load is caused by the unbalanced air supply in the terminal, and the maximum and minimum values are 22.4% and 5.9% of the basic cooling load respectively. The distribution characteristics of the test parameters can provide references for the design and operation control of air conditioning systems in airport terminals.
