John Lewis Partnership

Background

The John Lewis Partnership is the mother group of the most important companies dealing with retail sale in the UK: the supermarket chain Waitrose and John Lewis department stores.

Purposes

JLP has always been conscientious about environmental issues and, therefore, has commissioned the development of chiller units for comfort cooling within its offices in Exeter and Milton Keynes.

Project

Our R&D division, together with Danfoss Turbocor, has developed the first chiller in the world with the low impact refrigerant HFO-1234ze.

Results

The combination of HFO and Turbomiser has led to a TMA chiller that ensures high energy performance, capable of reducing energy consumption up to 40%. Moreover, thanks to the new refrigerant, the average power consumption is 27% lower, with a remarkable improvement in COP.
