From the foregoing description, it will be seen
that my invention provides an all-year-round
system for cooling and otherwise conditioning
and circulating the air during warm weather
55 periods, so as to keep the temperature in the
without the use of dampers or other means for
controlling the iiow and properly distributing 40
the air. It will be understood that a switch 19
may be provided for closing the circuit 61 inde
pendently o_f the switch 13 so that the fan I I may
be used alone or with the cooling means for dis
tributing the air in warm or mild weather, and 45
that a switch til may be provided to cut out _the
circuit 63 when the use of the air heating and
circuiting devices is not required.
'
It will be understood that there are seasonal
-periods of mild weather or climatic conditions >
during which the use of the air cooling and heat
ing units is not necessary as they are in hot
weather orcold weather to keep the air in the
passenger compartment at a comfortable tem
perature. During such mild weather periods the ,
passenger compartment comfortable during such ' air in the passenger compartment may become

conditioning and circulating the air during cool or
