Four CO2 (R744) heat pump units made by Italian HVAC&R manufacturer Enex have been installed as part of a four-pipe stand-alone transcritical CO2 system at a hotel spa resort in Sicily to provide space heating and air-conditioning, as well as domestic hot water for hotel guests.
According to Luca Bisetto, R&D Laboratory Manager at Enex, the system can operate in cooling and heating modes “simultaneously or independently of each other.”
The case study was presented by Bisetto during an HVAC and heat pumps session at the ATMOsphere (ATMO) Europe Summit on natural refrigerants. The conference took place November 15–16 in Brussels and was organized by ATMOsphere, publisher of R744.com.
