Study Finds ‘Novel’ Transcritical CO2 Ejector System Outperforms Conventional CO2 System Up to 82.5% in Hot Climate
The proposed system uses a multi-ejector, parallel compression and mechanical subcooling.
The proposed system uses a multi-ejector, parallel compression and mechanical subcooling.
The system is designed to provide dehumidification in low-temperature environments without the risk of freezing
The Norway-funded INDEE+ project is testing CO2 and ammonia systems in three locations as well as educating the market.
Iwatini Corporation, a Japanese manufacturer and supplier of natural refrigerant gases, has joined the world’s leading CO2 (R744) HVAC&R stakeholders as a bronze partner of the R744.com marketplace. The company, which was founded in 1930, supplies refrigerants such as R744, propane (R290) and isobutane (R600a) to manufacturers across Japan and Southeast Asia. High-purity R744 Iwatani’s…
The Japanese manufacturer produces a range of components for CO2-based HVAC&R systems.
This includes 110 units that have been installed at 40 universities across the country since 2006.
The systems were installed at the 31,000m2 (333,700ft2) cold storage and logistics facility in Sendai.
To date, the Japanese manufacturer has installed 410 transcritical CO2 units at 140 projects in Japan and Southeast Asia.
Projects can use CO2-, propane- or ammonia-based technologies to show how improved cold chains can reduce greenhouse gas emissions, operational costs and food loss.
Technical presentations from SCM Ref Australia and Danfoss representatives focused on R744 technologies for cold chain refrigeration.
