Description:

HiRef, in collaboration with distributor Unicool, supplied 4 air-cooled water chillers from the CDA series for the server room of the Copenhagen Metro. Consisting of independent refrigeration circuits with modulating compressors, the units reach a total cooling capacity of 500 kW and use a transcritical system with natural refrigerant R744. HiRef met the final customer’s needs by offering a customised solution. In fact, the four units, which replaced outdated machines, were installed in sites with significant installation constraints. The plant’s energy efficiency is another important aspect: the innovative gas cooler pressure optimisation system, a HiRef patent, maximises performance at every operating condition. The R&D department of HiRef and subsidiary Tecno Refrigeration, the Group’s competence centre on CO2, worked collaboratively on the project. A FAT was conducted with the customer present at HiRef’s plant in Tribano (Padova - Italy) and technical training was provided to the personnel in charge of installation. The future is transcritical.
