Mobile air conditioning (MAC) systems are installed in cars to keep drivers comfortable and cool while driving safely. Vehicles can heat up significantly in hot weather or under direct influence from sunlight, which is the reason why the capacity of MACs in passenger cars lies in the range of around 5 kW – enough to cool a small flat.
In 2006, 20 % of the global refrigerant emissions were from MAC systems in passenger cars. These direct emissions result from leakage during manufacturing, operation, servicing, repair and at end-of-life. Indirect emissions are due to increased fuel consumption caused by MAC operation.
|Subsector||Mobile air conditioning|
|Typical application||Almost every car nowadays has an air conditioning system installed. Usually, the compressor is connected to the car engine via a belt for direct transfer of mechanical power. Fans and controls are powered by electricity.|
|Typical end-users||Car manufacturers (OEM, original equipment manufacturers)|
|Main refrigerants used||HFC-134a, u-HFC-1234yf Charge size approx. 600 g|
|Natural refrigerant alternative||R-744 (CO2) HC-290 is sometimes used in the aftermarket|
|Growth rate / future demand||High: Strong market increase especially in emerging economies such as China and India Show on world map.|
