A method and apparatus for controlling an air conditioner having a motor-driven blower for creating air flow through an air passage which opens into a compartment through a plurality of outlets. The rate of air flow through the air passage is changed with a change of the number of outlet or outlets to be open, so as to avoid an undesirable air blowing rate caused by a change of resistance to air flow through the air passage.

An apparatus for controlling an air conditioner used in a process of treating air in a compartment to regulate its temperature, said air conditioner having an air passage terminating in a plurality of outlets opening into said compartment, comprising: outlet control means for closing each of said outlets to block air flow therethrough, said outlet control means being operable to open a selected number of outlets to permit air flow therethrough; air-flow control means for controlling the rate of air flow through said air passage toward said compartment; means for setting a desired value for compartment temperature and generating an electrical signal indicative of said desired compartment temperature value; a source for generating an electrical signal indicative of an actual value for compartment temperature; a control circuit for determining a value corresponding to a setting of said air-flow control means, said control circuit including means for selecting one of said outlets to open the same in response to a single-flow mode requirement and for selecting two of said outlets to open the same in response to a dual-flow mode requirement, said control circuit further including means for subtracting said desired value from said actual value to obtain a difference between said actual and desired compartment temperature values, said control circuit including means for comparing said difference with a first, second, third and fourth predetermined value, said second predetermined value being a negative value greater than said first predetermined value, said third predetermined value being a positive value less than said fourth predetermined value, and said control circuit further including means responsive to a dual-flow mode requirement for determining said value for a setting of said air-flow control means as: a first preset value when said difference is less than said first predetermined value; a first variable value less than said first preset value when said difference is between said first and second predetermined values, said first variable value decreasing with said difference increasing; a second preset value less than said first variable value when said difference is between said second and third predetermined values; a second variable value greater than said second preset value when said difference is between said third and fourth predetermined values, said second variable value increasing with said difference increasing; a third preset value greater than said second variable value when said difference is greater than said fourth predetermined value; and a circuit coupled between said control circuit and said air-flow control means for converting said determined value into a setting of said air-flow control means for controlling the rate of air flow through said air passage. *** BRS DOCUMENT BOUNDARY ***
