Ejectors Components

Ejectors are designed to improve the efficiency of carbon dioxide HVACR systems in warmer climates.

The ejector lifts the pressure of the gas from the evaporators into the receiver. The compressors are therefore compressing gas which is at a higher pressure and therefore lowering energy consumption of the system.

Increase in system performance of up to 25% in design operating conditions and up to 12% overall throughout the year.

EmJ and the specifically designed rack where it is installed reduces system complexity, as it can continuously and instantly adapt to specific operating conditions, ensuring an increase in system performance of up to 25% in design operating conditions and up to 12% overall throughout the year.
The CAREL Electronic Modulating Ejector (EmJ) has continuous modulation, which via dedicated control algorithms, allows the system to continuously adapt to the typical variations in operating conditions of refrigeration systems. This ensures the highest system efficiency, adapting to different system requirements in the most optimum way, especially at part load.

Energy Efficency
The Multi Ejector Solution™ offers tremendous energy saving potential of up to 10% on an annualized basis compared with the previous generation of trans critical parallel compression systems, with even greater savings occurring in the warmest ambient conditions. Compared to booster systems, savings can reach as high as 30% during the hottest hours of the year.

After years of intense engineering and field testing, our engineers have developed the Multi Ejector Solution™, which consists of two products: the Multi Ejector and the AK-PC 782A Pack Controller. This new solution makes it possible to go beyond traditional ambient temperature limitations and use transcritical CO2 refrigeration in all climates. In fact, the warmer the climate, the more you will gain from using this solution.

ATMO Intelligence, the Market Development division of shecco invites air-conditioning and refrigeration stakeholders to participate in a survey that assesses the F-Gas Regulation, sector by sector, while also looking into what should be included in an upcoming revision of the regulation.

Respondents select the sectors they are active in and complete a custom survey based on their interests. “With these results, we will produce a comprehensive report that will be shared with policymakers across the EU to drive more progressive change, particularly in terms of refrigerants and getting rid of harmful gases in all sectors – from transport refrigeration to domestic air conditioning,” said Ilana Koegelenberg, Market Development Manager at shecco.

Once completed, the report will be freely available for download.The survey should take around 15-20 minutes.
