An air conditioning system for a motor truck for establishing thermally confortable conditions for an occupant sleeping on a berth provided in a driver's cab. The system includes an air duct for distributing part of the conditioned air to vicinity of the berth and a damper adapted to open or close the inlet of the air duct. The system may include a microcomputer for automatically controlling the temperature of the introduced air and distributing the temperature-controlled air optimumly by automatically causing the damper to open or close the inlet of the air duct depending upon whether the berth is occupied or not, the temperature outside the driver's cab and the temperature in the vicinity of the berth.

1. An air conditioning system for a motor truck having a berth in a driver's cab comprising: means for introducing air; temperature control means for automatically controlling the temperature of the introduced air according to a program; air distribution means for distributing the temperature-controlled air into the driver's cab, said air distribution means including duct means for distributing at least part of the temperature-controlled air to the vicinity of said berth and switching damper means adapted to open or close the inlet of said duct means; means for generating a signal for carrying out the air conditioning mainly in a space in which said berth is installed; means responsive to said signal for changing said program to a program for carrying out the air conditioning mainly in said berth space; and actuating means responsive to said signal for causing said switching damper means to open said inlet of said duct means. 2. An air conditioning system for a motor truck as set forth in claim 1, wherein said signal generating means is adapted to generate said signal when said berth is occupied. 3. An air conditioning system for a motor truck as set forth in claim 1 or 2 further comprising an outside temperature detection means responsive to said signal for detecting the outside temperature, wherein when the detected outside temperature is lower than a set temperature, said switching damper actuating means is activated so as to cause said switching damper means to open said inlet of said duct means. 4. An air conditioning system for a motor truck as set forth in claim 1, wherein said signal generating means comprises a sleep switch which is manually operable and a berth switch which in turn responds to the occupancy of said berth and is adapted to generate said signal in response not only to the operation of said sleep switch but also to the operation of said berth switch. 5. An air conditioning system for a motor truck as set forth in claim 1, 2 or 4 further comprising humidity detection means for detecting the humidity in said driver's cab and a humidifier adapted to be activated when the humidity detected by said humidity detection means is lower than a set humidity. 6. An air conditioning system for a motor truck having a berth in a driver's cab comprising: means for introducing air; temperature control means for cooling and heating the introduced air to a desired temperature; and air distribution means for distributing the temperature-controlled air into the driver's cab, said air distribution means including first duct means for distributing at least part of the air controlled at a low temperature to a space in said driver's cab in which said berth is installed, first switching damper means adapted to open or close the inlet of said first duct means, second duct means for distributing at least part of the air controlled at a high temperature to the vicinity of said berth, and second switching damper means adapted to open or close the inlet of said second duct means. 7. An air conditioning system for a motor truck having a berth in a driver's cab comprising: means for introducing air; temperature control means including a microcomputer which generates according to a predetermined program a control signal for automatically controlling the temperature of the introduced air; air distribution means for distributing the temperature-controlled air into the driver's cab, said air distribution means including duct means for distributing at least part of the temperature-controlled air to the vicinity of said berth and switching damper means adapted to open or close the inlet of said duct means; means for generating an instruction signal for carrying out the air conditioning mainly in a space in which said berth is installed; said microcomputer being responsive to said instruction signal to carry out the air conditioning mainly in said berth space; and actuating means responsive to said instruction signal for causing said switching damper means to open said inlet of said duct means. 8. An air conditioning system for a motor truck having a berth in a driver's cab comprising: means for introducing air; temperature control means for automatically cooling and heating the introduced air to a desired temperature according to a program; air distribution means for distributing the temperature-controlled air into the driver's cab, said air distribution means including duct means for distributing at least part of the air controlled at a low temperature to a space in said driver's cab in which said berth is installed, and switching damper means adapted to open or close the inlet of said duct means; means for generating a signal for carrying out the air conditioning mainly in said berth space; means responsive to said signal for changing said program to a program for carrying out the air conditioning mainly in said berth space; and actuating means responsive to said signal for causing said switching damper means to open said inlet of said duct means. 9. An air conditioning system for a motor truck as set forth in claim 8 wherein said signal generating means is adapted to generate said signal when the berth is occupied by a crew. 10. An air conditioning system for a motor truck as set forth in claim 8 or 9 further comprising a temperature detection means responsive to said signal for detecting the temperature in the vicinity of the berth, wherein when the temperature detected by said temperature detection means is higher than a set temperature, said damper actuating means is activated so as to cause said damper means to open said inlet of said duct means. 11. An air conditioning system for a motor truck as set forth in claim 10 further comprising second duct means adapted to distribute at least part of the air controlled at a high temperature to the vicinity of the berth, second switching damper means adapted to open or close the inlet of said second duct means, and second damper actuating means adapted to cause said second switching damper means to open said inlet of said second duct means when the temperature detected by said temperature detection means is lower than the set temperature.
