Cool in the city

Star Refrigeration has supplied a bespoke plant for HVAC cooling at the London offices of a global investment bank.The existing refrigeration plant operated on R22, an ozone-depleting HCFC refrigerant, currently being phased out.

Working alongside a leading building services consultancy, Star designed a low maintenance cooling plant to improve efficiency, reduce noise and ensure reliability for the building's heating, air conditioning and ventilation system.

A challenging aspect to the project was retaining five air handling units (AHUs) which form part of the fabric of the building. The cooling coils in these units were supplied with direct R22 refrigerant. Star developed a flooded evaporator coil design that could be retrofitted to these AHUs.

This was achieved using its Low Pressure Receiver system design.

Star designed, built, installed and commissioned a bespoke air-cooled LPR refrigeration plant comprising four 600kW chillers operating on synthetic refrigerant R134a. The system features Turbocor oil-free compressors to provide high efficiency, reliability and low noise operation.
