Car air-conditioning system

An automotive air conditioning system for use in an automobile having storage means, power generation means for charging the storage means, and air conditioning means having an electric compressor driven by feeding from said storage means, comprising:

• control means for controlling power generation of said power generation means and an operation of said air conditioning means,
• wherein said control means calculates a permissible power consumption increment in said air conditioning means by adding a permissible power generation increment to a permissible discharging current increment on the basis of the permissible power generation increment allowable in said power generation means and the permissible discharging current increment allowable in said storage means to increase power consumption of said air conditioning means within the range of the permissible power consumption increment and to increase power generation of said power generation means by an excess of an increment of power consumption of said air conditioning means concerned over the permissible discharging current increment.

An automotive air conditioning system for use in an automobile having storage means, power generation means for charging the storage means, and air conditioning means having an electric compressor driven by feeding from the storage means, comprising:

• control means for controlling power generation of said power generation means and an operation of said air conditioning means,
• wherein said control means calculates a permissible power generation increment allowable in said power generation means to increase power consumption of said air conditioning means within the range of the permissible power generation increment and to increase power generation of said power generation means according to an increment of power consumption of the air conditioning means concerned.

An automotive air conditioning system for use in an automobile having storage means, power generation means for charging the storage means, and air conditioning means having an electric compressor driven by feeding from the storage means, comprising:

• current detecting means for detecting a discharging current value from said storage means and control means for controlling power generation of said power generation means,
• wherein, if the discharging current value exceeds a given permissible value, said control means increases the power generation of said power generation means from a given initial value on the basis of the discharging current value from the storage means detected by the current detecting means.

An automotive air conditioning system for use in an automobile having storage means, power generation means for charging the storage means, and air conditioning means having an electric compressor driven by feeding from said storage means, comprising:

• current detecting means for detecting a charging current value to said storage means and control means for controlling power generation of said power generation means,
• wherein, if the charging current value concerned is lower than a given lower limit, said control means increases the power generation of said power generation means from a given initial value on the basis of the charging current value to said storage means detected by said current detecting means.
