Hispacold HVAC for the Enviro500EV Charge, 100% electrical North American version of the double-decker ADL vehicle

The bus and coach manufacturer Alexander Dennis Limited has chosen Hispacold HVAC for the Enviro500EV Charge, its first double-decker bus with three axles and zero emissions for North America.

The installed system is a Phicool model compact integrated HVAC system with two independent circuits activated by two compressors. The system, equipped with 100% electric reversible heat pump and resistors, has a heat extension for extreme cold and a capacity of 2x21 kW for cooling and 2x18 kW for heat.

It also has a Driver HVAC Unit connected to the passenger HVAC equipment, with a cooling capacity of 3.5 kW and 4.2 kW, in heat mode.

With independent circuits for the upper and lower decks, the Phicool system provides coverage for a wide temperature range, both in cooling and in heat, and features a highly efficient heat function thanks to its heat pump. The first version of the Phicool model was conceived for the North American market, so the electrical engineering was designed in accordance with the UL Standards. However, it could also be developed to adapt to other electrical specifications.
