• CRII mechanical capacity control for CO2
• Line-start permanent-magnet motor (LSPM)
• Integrated intelligence with new operating concept in the CM-RC-01 IQ module
• Outstanding eco-efficiency and simple system integration
 
Compressor specialist BITZER will be presenting its new ECOLINE+ reciprocating compressors at Chillventa (NürnbergMesse, Hall 7, Stand 330) between 11 and 13 October.

With the new six-cylinder ECOLINE+ reciprocating compressors for transcritical CO2 applications, BITZER is setting a new benchmark in the use of CO2 as a future-compliant refrigerant at Chillventa 2016. The BITZER ECOLINE+ series boasts three key developments: a new motor technology has been developed for series production to achieve new levels of energy efficiency. Along with the mechanical capacity control, which is also new for transcritical CO2 applications, system efficiency has increased considerably in full and part-load operation. The new operating concept with the IQ modules was developed to take full advantage of the potential of the new technologies in terms of energy efficiency and straightforward integration into refrigeration systems, whilst ensuring simple service. These are also used in conjunction with the ECOLINE+ compressors.

‘We would like to make efficient CO2 technology simpler and easier to understand again, and thus significantly expand the range of applications with the forward-looking refrigerant. The ability to provide refrigeration solutions that are reliable over the long term will require expanding access to CO2 technology’, explains Rainer Große-Kracht, Chief Technology Officer of BITZER.

Specifically, further development begins with a line-start permanent-magnet motor (LSPM), which can be operated directly in networks with 50 or 60 Hertz. Incorporating permanent magnets has made it possible to significantly increase motor efficiency in full and part-load operation. This technology has been undergoing testing at BITZER and in selected systems out in the field for more than five years. With Chillventa, the LSPMs will be incorporated into the series production set for CO2 applications. These motors can be operated both directly in the network and in the familiar speed range with frequency inverters.

In addition to accommodating operation with frequency inverters, the new ECOLINE+ compressors can also be equipped with the new mechanical capacity control for the first time, enabling compressor operation with a refrigerating capacity between 10 and 100 per cent. The capacity control, which can comprise one controller in two-cylinder compressors and up to three controllers in six-cylinder compressors, is adjusted just as it is with the well-known capacity control of HFC refrigeration compressors.

The intelligent operating concept of the CM-RC-01 IQ module, which comes as standard, also ensures optimal efficiency for the oil supply, the oil heater and the new CRII capacity control, which is specially developed for CO2 applications. The interplay between CRII and CM-RC-01 allows the capacity to be adjusted virtually infinitely between 10 and 100 per cent. The CM-RC-01 IQ module makes it very easy and inexpensive to integrate the ECOLINE+ reciprocating compressor into a whole host of system configurations. The IQ module not only improves protective measures and options for monitoring compressors, but also expands their range of applications and thus offers users greater flexibility. This in turn makes it easier, for instance, to compensate for differences between summer and winter operation. The new capacity control has increased overall efficiency, as the CRII enables a more stable and higher suction pressure.

Thanks to the intuitive BITZER Electronics Service Tool (BEST) software as well as the monitoring sensors and actuators, which are prewired and preconfigured in the BITZER factory, the compressors are also very easy to configure and service.

Prepared for the future
‘Our issues of focus at Chillventa will be environmentally friendly refrigerants, energy efficiency and user-friendliness – and these coincide perfectly with the strengths of ECOLINE+,’ says Große-Kracht. ‘CO2 is one of the refrigerants of the future – we at BITZER believe that wholeheartedly. That’s because this refrigerant boasts a global warming potential (GWP) of 1, making it virtually climate-neutral.’ As a long-standing company, BITZER has extensive experience with innovative refrigeration technology, and has been promoting innovations in the industry for 80 years. In fact, BITZER has also been developing and manufacturing refrigeration compressors for subcritical and transcritical CO2 applications for more than 20 years. ‘The ECOLINE+ increases system efficiency and reduces the complexity of modern CO2 systems. At the same time, users gain long-term planning security in terms of legal requirements such as the F-gas Regulation and Ecodesign Directive,’ emphasises Große-Kracht at BITZER. ‘Thanks to the ECOLINE+, the refrigeration and air conditioning industry has taken a major step in the right direction in the area of CO2 applications. In short, the ECOLINE+ represents maximum energy efficiency, flexibility, simplicity and convenient operation.’
