The chimney effect in a super high-rise elevator shaft is significant in winter

which may cause difficulty in opening and closing the elevator doors and can produce obvious aerodynamic noise. In this study

the improvement effect of different cooling methods on the elevator shaft chimney effect is analyzed

including natural ventilation cooling with air volume of 2.12–6.68 m3/s

a radiant cooling panel with height of 10 m and temperature of 10 ℃

and a variable refrigerant volume cooling system (VRV) with cooling capacity of 20–100 kW. A super-high-rise elevator shaft thermal noise control scheme is proposed that combines natural ventilation and heat pump technology

and the feasibility of the proposed scheme is verified through on-site tests. The results show that when both natural ventilation and VRV systems are adopted

the pressure difference between the two sides of the elevator door is 49 Pa less than when only the natural ventilation system is adopted

and is 20.4 Pa less than when only the VRV system is adopted. At the same time

when both natural ventilation and the VRV system are adopted

the noise is 2.1dB less than that when only the natural ventilation scheme is adopted

and it is 1.6 dB higher than the noise when only the VRV system is adopted. Therefore

the simultaneous use of natural ventilation and VRV cooling systems can effectively reduce the chimney effect and simultaneously control the noise in the elevator shaft.
