Abstract
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.
Claims11
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.
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.
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.
An air conditioning system for a motor truck having a berth in a driver's cab comprising:
- means for introducing air;
