CAREL, Carrier join forces to tackle 'CO2 equator'

HVAC&R firms CAREL and Carrier Commercial Refrigeration Europe have joined forces to develop and industrialise a range of modulating ejectors in a bid to put an end to the so-called ‘CO2 equator’: the previously accepted geographical limit for cost-effective construction of CO2 systems in all food retail store formats.

The two companies have jointly developed a modulating ejector designed to increase the energy efficiency of transcritical CO2 systems in warmer climates – thereby extending the scope to use CO2 as a natural refrigerant across the spectrum, from smaller convenience stores to large hypermarkets.

Extending the use of natural refrigerants

CAREL Group Managing Director Francesco Nalini hailed the cooperation between CAREL and Carrier as ”an example of synergy in which different competencies combine to bring to market technologically innovative solutions”.

“Through this cooperation we have made a tangible contribution to extending the use of natural refrigerants, in line with our guiding strategy: innovate to generate energy savings and reduce environmental impact”, Nallini said.

CAREL brought to the table unique design experience acquired from developing its own range of continuous-modulation electronic valves and high-efficiency control solutions. Carrier’s experience of designing CO2 transcritical refrigeration systems, meanwhile, helped to significantly reduce fluid-dynamic design times.

The modulating ejector reduces installation costs and complexity by continuously and instantly adapting to specific operating conditions. Continuous modulation guarantees optimum energy efficiency by using just one simple auto-adapting device.

The two firms argue that simple installation and use will further ensure the success of their modulating ejector, which is configured automatically by integrated and intuitive controllers.

This makes technology based on quite complex physical principles – the Venturi effect, in the case of these ejectors – easily usable, Nalini argues.

The two companies will be introducing their new modulating ejector at the ATMOsphere Europe conference in Barcelona on 19-20 April.
