Alfa Laval’s Rolf Christensen presented a CO₂ transcritical heat pump project in Lund, project inspired by the success of the Japanese Eco Cute heat pump, using Alfa Laval heat exchangers. To provide domestic hot water and heating for 24 apartment buildings with more the 400 apartments two different capacity heat pump units were developed: 54 and 68 kW. According to Christensen the total annual energy savings for this project are about €1.1 million, and the pay back period is expected to be around 5 years.
