Two high performance Carrier air-cooled chillers with a combined cooling capacity of 1.17MW have been installed at The Royal Exchange in the City of London as part of a major refurbishment.

The Grade 1-Listed building, located opposite the Bank of England, has undergone a complete refurbishment of its upper storey serviced office accommodation and a key element of the project was to replace and upgrade the building’s air conditioning.
The offices are part of The Royal Exchange in London
Allan Wilkinson, managing director of contractor  JSA Service, said: “The client required a high efficiency solution that would deliver top quality comfort conditions and operate with low noise. Reliability and resilience were key. The Carrier chillers provided an excellent solution, offering low noise, superior reliability and optimal efficiency, especially at part load.”
The AquaForce 30XAV-600 units are designed to meet all current and future requirements in terms of energy efficiency and operating sound levels. This is achieved through the combination of proven best-in-class technologies that include:

  • High-efficiency variable-speed Carrier twin-screw compressors
  • Variable-speed condenser fans
  • Novation high efficiency heat exchangers with micro-channel coil technology
  • Mechanically cleanable flooded evaporator
  • Carrier’s new Touch Pilot control system

As standard, the chiller can provide an evaporator leaving temperature down to 3.3 degrees Celsius, with proven operation for outdoor air temperatures ranging from minus 20 degrees Celsius to 50 degrees Celsius.

Due to logistics challenges on site, JSA Service had to completely dismantle the chillers to enable individual components to fit through a small access hatch. The chillers were then reassembled in position, connected up and the system commissioned.

Chris Bates, director, JSA Service, worked with the technical services team to deliver the project. He said: “It was the first complete chiller disassembly and reassembly we’ve undertaken, necessitated by access issues. The fact that it is a Grade 1-Listed building also required great care in the planning and execution of the project. We worked closely with John Foster of Cooling Technology, Carrier’s sales agent, who provided excellent technical support throughout the project.”

The project was completed and handed over to the client within four weeks, two weeks ahead of schedule.
