ABSTRACT:
The components of a compact, dual stage air conditioning system are assembled within a common housing in which an evaporator airflow passage is separated from a condenser airflow passage by an interior panel. Dual stage operation is provided by a pair of evaporator coils which are interleaved about a common evaporator core, and by a pair of condenser coils which are interleaved about a common condenser core. A control circuit automatically enables single stage operation when on-board generator power is applied, and automatically enables dual stage operation for increased cooling capacity when commercial utility power is available.
