Enex has been actively developing solutions to increase CO2 system efficiency in warm ambient climates like Spain and Italy. Using parallel compression and ejectors in unison, the company has realised significant efficiency gains and cost (first cost + energy cost) reductions. With more than 60 units installed with auxiliary compressors and more than 20 units using ejectors, the company’s accumulated data proves the energy savings of Enjector® technology can be as
The continually diminishing CO2 efficiency equator was a hot topic at ATMOsphere Europe 2015. Several system manufacturers presented the methods by which CO2 transcritical system efficiency can be improved, with ejector technology taking the spotlight. According the several presenters the end of the so-called “CO2 equator” is in sight. + VIDEO
ATMOsphere Europe 2015 provided a platform for the latest heat pump innovations including ENEA’s joint case study on a heat pump with a unique two-cylinder compressor, designed to cater for the European market. boostHEAT showcased its integrated heat pump/boiler solution while Mitsubishi Heavy Industries (MHI) and Sanden outlined the increased migration of their products from Asia to Europe.
Kaori’s entrance to the Chinese commercial heat pump market in 2015 was a welcome one. With the revised China Environmental Protection Law to take effect in 2015, the company is intent on meeting the increasing demands for CO2 heat pumps.
R744 innovations from Japan Part 2: integrated systems and improving CO2 system efficiency in warm climates
In part 2 of our reporting on the CO2 technology innovations discussed at ATMOsphere Asia 2015 we focus on the presentations from Carel, Bitzer, and Danfoss on integrated CO2 systems and technologies to increase the energy efficiency of CO2 in warm climates. These include more traditional systems such as mechanical subcooling and newer ones such as parallel compression and ejectors.
The use of CO2 as a refrigerant is becoming increasingly widespread in food processing industries, and is beginning to make inroads in industrial heat pump applications. TINE Dairy, which is Norway’s largest producer, distributor and exporter of dairy products, is committed to upholding its sustainable profile and strives to keep up to date with the most climate friendly and energy efficient technologies. With this in mind, TINE’s factory close to the city of Trondheim in
The ROXSTA CO2 rack is the latest edition to TEKO’s line of advanced technology using natural refrigerants. Since 2006, TEKO has installed more than 1,100 CO2 racks with the next generation ROXSTA part of the company’s environmental evolution.
ATMOsphere Asia 2015 unearthed plenty of positives for CO2 heat pump applications as Mitsubishi Heavy Industries explained the field test results for its Q-ton, the world’s first two-stage compressor for commercial use. Meanwhile, Yamato and The Coca-Cola Company demonstrated the benefits of their respective peak shift technologies, the Ultra-Eco-Ice thermal storage CO2/brine refrigeration system, and an award-winning CO2 vending machine.
