Abstract
A module is provided for attachment to the roof of a bus and includes all of necessary components for conditioning the return air from the passenger compartment and delivering conditioned air thereto. Each module includes an evaporator section, a condenser section and a power section including a compressor and an inverter. The evaporator sections have a return air compartment that extends a substantial distance across the roof of the bus such that a single design can meet the needs of various return air duct installations of various types of buses. Provision is made to interconnect a evaporator discharge opening with a supply air duct for the bus by way of a flexible duct having integrally formed end plates for connection by way of fasteners. The lower end plate which is secured to the supply air duct also includes an upstanding flange for connecting a protective cover thereto.
