Alldales Inverter Drives Commissioned for New Hospital

Alldales Drive Systems has been commissioned to fit inverter drives to air handling units being supplied as part of the controls package to service the brand new University College Hospital (UCLH) currently taking shape in the heart of London. The hospital development has been designed and built with energy conservation very much in mind. The new generation of HVAC specific Alldales compact inverter drives have been specified as part of an integrated approach designed to provide responsive, local climate control while delivering significant energy savings in an area (HVAC) which traditionally accounts for the lion's share of building energy consumption. The commissioning of the drives follows on from a full harmonics analysis carried out by Alldales in conjunction with M & E Consultants for the project, DSSR.

The new UCLH development situated on the busy Euston Road is being carried out in two phases. Phase One - the main wing, consisting of a 97m high tower and podium, which will be completed in 2005. Over 200 inverter drives ranging from 5Kw to 75Kw units have already been fitted to air handling units throughout the site in plant rooms serving administration blocks, wards and theatres. One of the country's busiest Trusts, the new UCLH hospital will have 669 beds and will also act as a key centre for clinical, research and teaching activities.

By varying the speed of the motor to automatically adjust airflow to match changing occupancy and usage requirements, inverter drives can reduce energy consumption by as much as 50%, compared with traditional control vane and throttle control methods where motors are kept running at full speed.

Linked to a Building Management system as part of an integrated solution, inverter drives provide detailed data to help track and control energy performance. With initial investment costs recoverable under DETR's Enhanced Capital Allowances Scheme, inverter drives are proving to be a cost-effective option for specifiers looking at long term solutions for applications with large-scale energy requirements, such as the new University College Hospital.
