PUMC, China

A well known landmark in Beijing, the Peking Union Medical College Hospital is a Class A tertiary comprehensive hospital committed to delivering state-of-the-art clinical care, innovative scientific research and rigorous medical education. It is designated by the National Health and Family Planning Commission as one of the national referral centers offering diagnostic and therapeutic care of complex and rare disorders, as well as one of the earliest Chinese hospitals offering medical care to senior leaders and foreign patients. PUMCH enjoys high reputation for its full range of disciplines, cutting-edge technologies and outstanding specialties. From 2009 to 2015, PUMCH has consecutively topped the “Best Hospital Ranking in China”, which was published by the Hospital Management Institute, Fudan University.

In 2012 the decision was made to renew the on premise laundry, and an old wing of the hospital was rebuilt to suit.

The movement to reduce industrial waste and pollution in China has been growing, and the decision was made at the start of the laundry project to reduce environmental impact to a minimum.

Space and height limitations determined the selection of washing machinery and a total of 13 washer extractors were installed to meet the daily requirements of this large and busy hospital, typically between 10-15 tonnes of clean sterile linen per day, using 20,000 litres of water per hour.

Aquatherm was consulted at an early stage, and worked with machine suppliers and engineers to find a solution within the limited space available.

Underneath the main wash house there was a disused cellar with barely 1.5m headroom. Into this space two large buffer tanks were constructed, in between these tanks a specilly constructed low headroom Aquatherm was fitted, linked to a set of controls on the washroom floor above.

All the hot waste water is collected in one of these tanks and pumped through the Aquatherm before going to drain at a temperature a few degrees above the incoming cold water.

The incoming fresh cold water flows through the ‘clean side’ of the Aquatherm, reducing steam use for washing by 80% and making savings of gas 600 M3 per day, RMB 550,000 per year. The financial savings were sufficient to pay for the entire installation in well under 2 years, and reducing the all important carbon footprint of this site.

The project was managed throughout by Leon Chen who has many years of experience in the Chinese Laundry market, and whose company A Kua Sen is actively engaged in the development and sale of water and energy systems.
