1. A climate control system for a vehicle, the climate control system configured for using one or more combustible coolants and for installation on a vehicle roof, the climate control system comprising:
an air treatment unit;
a compressor unit; and
an electrical switch box designed as a closed assembly and is operatively connected to an air supply assembly by which air from areas outside coolant-carrying segments of the climate control system is guided into the electrical switch box in such a way that an overpressure is created in the electrical switch box to prevent the one or more combustible coolants from flowing into the electrical switch box.
