Italian Supermarket Claims Big Energy Gains from HFO/CO2 Cascade and Heat Recovery
First supermarket 1234ze/CO2 cascade with heat recovery expects savings of over a third vs. conventional system
Honeywell has announced that its Solstice ze (HFO 1234ze) refrigerant is being used in a new supermarket application that combines several systems to improve energy efficiency. The refrigerant is being combined with carbon dioxide in a new supermarket cascade system designed to deliver heating, air conditioning, and refrigeration in one comprehensive, low-carbon solution.
Italy-based refrigeration specialist Tecnologie del freddo (TDF) worked with Honeywell to design a cascade system capable of satisfying all of the refrigeration, heating, and air conditioning needs for a new Unes/U2 supermarket in Parma, Italy. This solution replaces conventional boiler and air conditioning units, using a heat exchanger to capture the energy generated by the refrigeration system to heat the store, provide hot water, and cool the store in the summer.
