Night ventilation and active cooling coupled operation for large supermarkets in cold climates
چکیده انگلیسی

Night ventilation and active cooling coupled operation strategy is studied for the large supermarkets in cold climates in China. The model on the thermal storage of the indoor goods is set up. Furthermore, based on the thermal balance of the whole room, the temperature change model is founded. The coupled operation process is simulated for the typical supermarket buildings. The overall energy consumption of the system is analyzed. The result shows that the opening time, duration and air flow rate of night ventilation all affect the performance of active cooling. Active cooling will influence night ventilation too. It also turns out that the coupled operation leads to shorter operation time of active cooling. The various operation modes are given at different climatic conditions. Compared with the normal active cooling system, the coupled operation system can save energy at 2.99 kWh/(m2 a) in cold climates in China while 3.24 kWh/(m2 a) in Harbin.
