This year’s show highlighted an increasing shift towards electric buses, whose range can be extended with natural refrigerant heat pumps.
Busworld took place October 18-23 in Brussels, Belgium.
Natural refrigerant products, especially heat pumps, had a strong presence at the Busworld conference, the annual meeting on buses and coaches that took place in Brussels, Belgium from October 18-23.
These products tie in well with the unofficial theme of this year’s show, bus electrification, which is impacting vehicle design.
Today, e-buses represent 18% of all buses worldwide (compared to 7% in 2015), according to a BloombergNEF report published in May this year. According to the report, global sales for e-buses are expected to grow at a rate of 33.5% annually until 2025. Most of these e-buses still use R134a for cooling, but as the drive towards phasing down HFCs intensifies globally, natural refrigerants such as R290 and CO2 are becoming popular alternatives. Natural refrigerant heat pumps offer the ability to extend the driving range of electric vehicles.
As such, it was no surprise that natural refrigerant products, particularly heat pumps, had a strong presence at the show. Even at the Busworld Awards, which took place on October 17, German GEA Bock’s StarCO2mpressor compressor for heat pumps was honored with an Innovation Label. According to GEA, the units offer “the industry’s lowest overall height and the lowest weight.”
Natural refrigeration innovation at its best
Other than GEA’s winning product, here are some other natural refrigerant product highlights from Busworld:-- Area Cooling Solutions (headquartered in Barcelona, Spain) presented its R744 Panasonic C-CV753L0U compressor for train passenger cabins, equipped with an inverter specific for e-bus applications.
