Responsible refrigeration technology at the Chillventa

Under the slogan “responsible refrigeration“ Bock presents at the Chillventa 2010 compressor solutions for environmentally friendly refrigeration- and air-conditioning systems.

One of the biggest challenges of our time is to counteract climate change. In particular, the emission of carbon dioxide CO2 and other climate-changing greenhouse-gases has to be reduced.

An important role plays refrigeration- and air-conditioning technology. The technical production of refrigeration in Germany adds up to about 14% of the total energy consumption. An impressive number that makes clear that the refrigeration- and air-conditioning technology might be one of the biggest energy consumers, but also has a big energy-saving potential.

Therefore it is obvious that especially in the refrigeration- and air-conditioning industry there is a lot of discussion about future technologies to find possible saving potential.

From 13.-15 October, Bock presents at the Chillventa 2010 in Nuremberg its current solutions for economic and environmentally friendly refrigeration- and air-conditioning systems.

The natural solution CO2

In the last few years, the refrigerant CO2 was established in various applications, such as parts of the supermarket sector. A development that will even gain momentum in the next years. With ten years of experience as a pioneer of this technology, Bock presents for the first time at the Chillventa the new 4-cylinder compressor models HG34 CO2T for the use in transcritical CO2 applications.

Full commitment for highest efficiency

When it comes to the topic of efficiency good is not good. Therefore Bock works continuously on the development of our current compressors.

The result – compressors especially optimised for the use with 134a. Those compressors optimised for the specific characteristics of R134a achieve a higher efficiency and therefore increase the annual capacity of the refrigeration plant. As the first compressors in R134a version, Bock presents at the Chillventa 2010 models of the type HG5…R134a.

With the Bock e-series the company also presents a further development in terms of efficiency optimisation. The new generation of semi-hermetic compressors is optimized for all standard refigerants.

As a first model of this series, Bock presents at the Chillventa compressors of the type HG34.

Awarded solution - energy saving with the EFC-system

An essential element of the efficient operation of refrigerating plants is a regulation that is conform to the respective demands. In many cases such a regulation of the compressor via a frequency converter accounts for a saving potential of 25% and more.

Through a continuous variable speed control of the compressor, the frequency converter ensures the automatic adaptation of the produced refrigeration capacity to the actual demand. Already since 2004, Bock offers with the EFC-system (Electronic Frequency Control) the Plug & Play solution for the frequency-converter regulation of compressors.

At the Chillventa, Bock presents the EFC Plug & Play system that was awarded with an innovation price for refrigeration technology by the German Environmental Minister.

A natural alternative – hydrocarbons

Whereas the use of synthetic refrigerants is already limited in some countries due to their contribution to the greenhouse effect, the trend goes towards natural refrigerants that are a real alternative to synthetic refrigerants. A well-known solution among them – hydrocarbons.

Based on the compressors of the current Bock semi-hermetic program and the established standard product range, Bock presents at the Chillventa a compressor version especially for the use with hydrocarbons – the so-called HC-compressors. Those compressors are suitable for all hydrocarbons and have, compared to compressors for standard FKW- and HFKW-refrigerants, safety-related modifications due to the flammability of hydrocarbons.

The refrigeration- and air-conditioning industry is responsible for future generations. With the Bock compressor program at the Chillventa 2010, the company presents practically oriented solutions that are already available today to build environmentally friendly refrigeration plants.

In hall 4, stand 316, the company is looking forward to your visit.
