Abstract: A travel coach having a passenger and a driver section separated from a cargo area by a floor. The cargo area is divided into bays serviced by large bay doors. An air conditioning system is mounted in the cargo area and includes two electrically driven compressors mounted in one bay and a condenser unit mounted in a neighboring bay. The condenser unit contains a first heat exchanger circuit for servicing a pair of evaporators units and a second heat exchanger circuit for servicing at least one other evaporator unit. The evaporator units are mounted in existing ductwork located beneath the floor of the coach and provide cooling to the passenger and driver sections of the coach. Refrigerant from the evaporators is returned to the compressors to complete the two refrigerant cycles.
