The Electric Power Research Institute has assessed the benefits of replacing a traditional hydronic air-conditioning system with a low-charge ammonia chiller and CO2 convection loop.
Daniel Clark, Managing Director of Isentra, believes that transcritical CO2 will make deeper inroads into traditional ammonia territory than HFC’s ever did.
The company exhibited its 20HP CO2 condensing unit as well as its “C-LTS” NH3/CO2 cascade system at FOOMA Japan 2021.
Japan’s leading OEMs will show several new additions to their CO2 lineups at first FOOMA in two years.
Ammonia/CO2 systems are currently the most popular.
The 3,000kW (853TR) combined system will be supplied by Tewis Smart Systems.
Ammonia is the traditional refrigerant, while CO2 is a newcomer in the country’s cold-storage market.
By the end of March, the company will have eliminated all HCFCs, using ammonia and CO2 systems instead.
The Canadian contractor will no longer make systems that use HFCs or HFO blends like R513A.
Howe’s 1,000lbs/day unit is being used by Raley’s store in California.
