Simulates and compares the indoor temperature field and velocity field under double nozzle outlet air supply with those under single nozzle outlet air supply. Studies the outlet air velocity of double nozzle outlets. Also simulates the indoor temperature field in all outdoor air mode in transition seasons at different outdoor temperatures, and analyses the energy saving effect.
