Resumen:
Un centro tecnológico español con amplia experiencia en el sector de elevación ha desarrollado un módulo de carga que almacena la energía generada en el frenado de un ascensor. Esta energía se almacena en un banco de ultra capacitadores y se suministra a los sistemas auxiliares del ascensor. El dispositivo reduce el consumo de energía en estado de stand-by y mejora la clasificación energética. El módulo puede conectarse a cualquier variador de frecuencia acoplado al motor del ascensor. El centro tecnológico está interesado en licenciar la tecnología patentada a un socio del sector de elevación.

Tittle:
Energy recovery system for lifts in direct current
Summary:
A Spanish technology centre with a wide expertise in the elevation sector has developed a load module that saves the energy produced by the elevator when braking. This energy is stored in an ultra-capacitors bank and is supplied to the elevator auxiliary systems. The device reduces energy consumption in stand-by phases and improves energy classification. The centre would like to licence this patented technology to a partner working in the lifting sector.
Description:
A Spanish technology centre with a wide expertise in elevation and lifting systems has developed an energy-saving module for lifts working in direct current (DC). This module saves the lift energy generated when stopping in order to use it afterwards for the lift´s auxiliary elements. The energy is stored in an ultra-capacitors bank, allowing to reduce energy consumption in stand-by phases and improving energy classification. The saving module may be connected to any kind of frequency converter attached to a lift engine.

The module may provide the stored energy both when the lift is in operation and when it is at rest. Its use is particularly important in residential lifts, due to the important consumption of the lift in stand-by mode in this case.

This technology reduces the consumption of electric energy by 10 to 20%, which can increase the elevator´s energy rating classification.

The developed energy recovery system has the following features:
· Modular system adaptable to different elevator power levels
· Variable power supply to the auxiliary systems (24V DC / 48V DC)
· Can be used with any frequency converter and doesn´t need the use of any transformer (involving cost reduction).
· It is a scalable development that allows its use in high power elevators thanks to the connection of several modules in parallel.
· It is a plug and play system which makes it easily installable and can be used with various types of elevator.
· Both for rehabilitation and renovation of elevators and for new elevators.

The technology is already patented and the technology centre would like to transfer it through an operating license to a company working in the elevation sector. This company would take care of integrating the module in its elevators or including it in its portfolio.

The licensing company should have a minimum level of development skills in order to take care of further changes and adaptations to its clients´ requirements and of post-sales service and other maintenance activities.

As part of the licensing agreement, the technology centre will also transfer the technical knowledge required to sell or to use this technology. In addition, it might be possible to include further technical assistance if required.
Advantages and Innovations:
The energy-saving system supplies power to the lift´s auxiliary elements, delaying the entry of these elements in a stand-by state, which extends the service life of the auxiliary elements.

The module may provide the stored energy both when the lift is in operation and when it is at rest. Its use is particularly important in residential lifts, due to the important consumption of the lift in stand-by in such case.

This technology reduces the consumption of electric energy by 10 to 20%, thanks to the reduction in the consumption of the auxiliary elements, which represents a significant energy saving. The achieved energy improvement can increase the elevator´s energy rating classification.

The module may be used with a wide range of systems (different elevator power levels, variable power supply, any kind of frequency converter,...). It´s a plug and play system and doesn´t need any transformer, so installation costs are reduced. In addition, it might be used in both existing and new installations.
