BITZER is committed to ensuring long-term business success and growth for its customers and partners, which is why the specialist in refrigeration, air conditioning, and heat pump technology will be focusing on natural refrigerants and solutions for increasing energy efficiency in new and existing systems at Chillventa 2024.
‘SHAPING THE FUTURE WITH YOU’ will be the company’s trade fair motto at stand 350 in hall 7.
refrigerants and energy efficiency
The refrigeration, air conditioning, and heat pump industry can expect changes in the areas of refrigerants and energy efficiency as a result of the Montreal Protocol, the EU F-Gas Regulation, the Ecodesign Directive, and potential PFAS bans.
"But what we generally view as challenges of the future can also offer major opportunities," says Martin Büchsel, Chief Sales and Marketing Officer at BITZER.
Shaping the future
"We are doing what we can to ensure they benefit our customers and partners. Especially when it comes to refrigerants and energy efficiency, we not only offer solutions based on products but can also provide ideas for concepts."
"For the past 90 years, we at BITZER have been driven by the vision of shaping the future with our customers. We represent #morethanacompressor and #greencompetence."
Natural refrigerants for future-proof systems
BITZER has offered components for R717 (ammonia) since 1973, for hydrocarbons since 1990
With F-Gas Regulation 2024/573 and potential PFAS bans, Europe is heading for a future based on minimal use of HFCs.
To ensure investments over the long term, BITZER expressly recommends natural refrigerants when planning new refrigeration, air conditioning, and heat pump systems based on BITZER components in the EU. BITZER has offered components for R717 (ammonia) since 1973, for hydrocarbons since 1990 and for R744 (CO2) since 1998.
ECOLINE 8-cylinder reciprocating compressors
At Chillventa, the company will be presenting innovations from its extensive product portfolio for natural refrigerants.
For example, the ECOLINE 8-cylinder reciprocating compressors for subcritical CO2 applications expand the series to include higher capacity ranges with the refrigerant R744 (CO2) – especially for industrial refrigeration. The compressors are designed for high standstill pressures of up to 80 bar.
ECOLINE PRO, CS PRO, and ORBIT PRO series
BITZER is also the only manufacturer to include reciprocating, screw, and scroll compressors for R290 (propane) in its portfolio. The company will be showcasing these along with the ECOLINE PRO, CS PRO, and ORBIT PRO series at Chillventa.
Components for R717 (ammonia) will round off the BITZER product portfolio for natural refrigerants at Chillventa. Open drive OS.A105 screw compressors come in three displacement volumes – 1400, 1700, and 2000 m3/h at 2900 rpm and offer high capacities for industrial refrigeration.
Energy-efficient systems are an absolute must
Energy efficiency is more important than ever before for both new and existing systems
When it comes to financial business success and efforts to increase sustainability, energy efficiency is more important than ever before for both new and existing systems.
Efficient systems not only reduce energy and operating costs and increase system availability but also decrease the indirect emissions associated with energy consumption and thus the carbon footprint. The great potential often lies in the details.
LSPM motor technology
Designed to fulfill market requirements, BITZER compressors offer maximum efficiency and boast a long lifetime.
One example is the line-start permanent-magnet (LSPM) motor technology of the ECOLINE+ series, which uses high motor efficiency and low heat input into the refrigerant to reduce energy consumption.
VARIPACK frequency inverter and VARISTEP mechanical capacity
Advanced capacity control is essential when it comes to further improving efficiency in full and part load, which is why BITZER offers a range of options that are optimally tailored to its compressors and enable precise capacity adjustment based on actual refrigeration and heating requirements.
At Chillventa, the company will offer information about the opportunities provided by the VARIPACK frequency inverter and VARISTEP mechanical capacity control. These technologies can be optimally combined in new systems, but also offer benefits when it comes to retrofitting existing systems for optimizing energy consumption.
Compressor capacity
Raising the evaporation temperature by 3 Kelvin can improve efficiency by up to 12 percent
Due to a wide range of capacity modulation of the compound system, both the minimum load and varying cooling and heating loads up to the maximum load are optimally covered. Precise capacity control optimizes dynamic system behavior, improves control accuracy (CF), and lowers temperature differentials in heat exchangers, thus reducing fluctuations in pressure, which result in losses, and high cycling rates. Calculations demonstrate that precise control of compressor capacity can increase system efficiency considerably.
Raising the evaporation temperature by 3 Kelvin can improve efficiency by up to twelve percent while reducing the condensing temperature by 1 Kelvin can improve efficiency by another two to three percent.
IQ MODULE CM-RC-02
Focusing on energy efficiency, the new generation of the IQ MODULE CM-RC-02 will be one of the BITZER product highlights at Chillventa 2024. It has been a standard feature of ECOLINE reciprocating compressors of the C3 series and higher since the beginning of the year and lays the foundation for even higher efficiency in compressor operation and increased availability.
In addition, intelligent functions such as monitoring key operating parameters and a user-friendly operating concept simplify compressor installation, commissioning, and maintenance. Thanks to extension boards, the IQ MODULE also simplifies the connection and operation of VARISTEP capacity control.
Energy efficiency
"With the IQ MODULE, we demonstrate that it is possible to improve energy efficiency without increasing complexity. The IQ MODULE was developed to simplify everyday operations for installers and contractors," says Rainer Große-Kracht, Vice-Chairman of the Management Board and Chief Technology Officer of BITZER.
There are special performance kits available for retrofitting existing compressors. Due to the IQ MODULE, VARISTEP capacity control can also be retrofitted at any time to improve efficiency.
