Tata Motors and MAHLE partner to develop a prototype Secondary Loop Mobile Air Conditioning System on a vehicle

"Tata Motors Limited and MAHLE have signed a joint development agreement for designing and developing a Secondary Loop Mobile Air Conditioning System (SL-MAC), under the aegis of United Nations Environment.

In the SL-MAC system, the alternative refrigerants first cool a secondary fluid/coolant, which in turn cools the air to comfortable temperatures inside the vehicle cabin. This process allows the safe use of slightly flammable refrigerants that have a low GWP and in turn achieves high cooling capacity, minimizing the losses and achieving an optimized overall thermodynamic...
