The Italian manufacturer’s controllers are designed to optimize the performance of integrated HVAC&R systems in commercial and industrial applications.
As of September 2022, the German wholesaler had installed transcritical CO2 systems at 153 of its 700 stores, with a plan for 40 more transcritical installations this year.
A supermarket in northern Italy has reduced its energy bills by an estimated €18,000 (US$19,500) per year by installing a CO2 (R744)-based rack that integrates the store’s refrigeration, HVAC and hot water production requirements into a single system. Previously, the store had a direct expansion R404-based refrigeration system, a methane-fueled boiler for heating and hot…
The Danish Technology Institute is partnering with Denmark-based manufacturer Unic Air to create a prototype of the HVAC unit for testing.
ETE reduces the production of flash gas in transcritical CO2 systems at high ambient temperatures, promoting efficient operation of the system’s compressors.
The store will save around €11,000 a year by integrating its heating and air-conditioning into its CO2 refrigeration system.
German OEM TEKO Refrigeration has introduced a patent-pending heat exchanger, the TECO2nditioner, which is designed to reduce the suction and discharge temperatures of medium-temperature compressors in its transcritical CO2 booster systems. This in turn lowers and stabilizes oil temperatures, maintaining lubrication and extending the lifetime of the compressors. The TECO2nditioner, unveiled at the Chillventa trade…
The units employ two-stage rotary compressors to operate efficiently in temperatures up to and beyond 43°C (109.4°F).
Bente Tranholm-Schwartz, Deputy Head of Unit at DG Climate Action at the European Commission (EC), pointed to natural refrigerants as the way forward in Europe in view of the likely stricter EU F-gas Regulation and upcoming REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) regulation of PFAS chemicals that is targeting f-gases. She made those…
