Case Study - Thomas More Square

Customer: Thomas More Square/Chiller Manufacturer and Consultant

Project: Thomas More Square (London)

Duration: 14 Months Hire Period

 

Customer Requirement:

An essential requirement for cooling was needed by a major chiller manufacturer and a consultant for a large high profile office block in London. There were two chillers in the building, one beyond repair and the other barely running with an engineer constantly on-site maintaining them. The ambient temperatures were getting hotter, a solution was needed and it was needed quickly.

Carrier Rental Systems Solution:

The requirements of the building were assessed; Carrier Rental System’s solution was to provide 2 x 1200kW air cooled chillers which would give run and standby operation. The benefit of this would give the customer 2 circuits and 2 semi hermetic screw compressors per machine; giving the ability to manage variable loads with minimum power input at part load. After looking at possible positions for the chillers the only location was to build a scaffold platform over the shrubbery and place the chillers on it. Therefore, help was enlisted in the form of a crane company who lifted the chillers over the trees and positioned all of the equipment.

Once the chiller was in place, purpose made 6” flanges, flow and return hoses were assembled and connected into the customer’s chilled water system with the help of a pipe fitting company to make the final pipe work modifications. The customer only had 15kv power on-site so we supplied a transformer to reduce down to 400 volt, with a HV specialist on-site to test and commission.

• Equipment List – 2 x 1200kW Chillers/1 x 15kv Transformer/Cables and 6” Flanged Hose.
• Benefits to Customer – The customer was able to provide its tenants with a comfortable working environment.
• Outcome – Carrier Rental Systems offered a solution, delivered, implemented and had a system up and running within 36 hours of receiving an order.
