Inner Mongolia Hailiang Real Estate Development Co., Ltd. is a wholly-owned subsidiary of Hailiang Group. At present, it has invested more than 4 billion yuan in Hohhot to build Hailiang Plaza, a landmark project in Hohhot. Hailiang Real Estate will rely on Hailiang Plaza, Buildings A, B, C, and D of Hailiang Plaza are business office apartment buildings that integrate office and accommodation. Each of them has 6 elevators under the Guangzhou Hitachi brand. The floor is 35 floors, the elevator power is 30KW, and the elevator speed is 2.0m/s.

This article mainly introduces the application of IPC-PFE elevator energy-saving feedback device in Otis brand elevators. The on-site operation shows that the transformation of returning the regenerative energy generated by the motor in the state of regenerative power generation to the power grid is successful. From the perspective of electric energy feedback technology, it shows that the energy-saving of the elevator is feasible.

In recent years, the hospital’s energy consumption has remained high, which has increased the burden on the hospital and affected the development of the hospital. The most prominent is the power consumption of the elevator. The hospital is constantly coming and going, so the frequency of elevator use is very high, which naturally consumes electricity. The amount is large, so the hospital decided to install elevator energy-saving feedback to reduce the electricity consumption of the elevator in the hospital.

IPC elevator energy-saving feedback has settled in a public hospital-Xiamen Maternity and Child Health Hospital! It proves once again that the installation of elevators and energy-saving feedback has become a trend in hospitals across the country. How to reduce operating costs will become the focus of hospital logistics. Not only hospitals can be retrofitted, but government buildings, office buildings, hotels, guesthouses, residential communities, etc. are also suitable for retrofitting.
