Air conditioner for vehicle

Abstract

An air conditioner for a vehicle includes a blower that generates blown air; a heating heat exchanger that heats the blown air by heat exchange between the blown air and a heat medium; a target temperature setup device that sets a target temperature for a passenger compartment in accordance with an operation performed by an occupant; and a control device that determines the availability factor of the blower in accordance with the temperature of the heat medium wherein the control device increases the availability factor of the blower as the target temperature increases.

1 . An air conditioner for a vehicle, comprising:
 a blower that generates blown air;   a heating heat exchanger that heats the blown air by heat exchange between the blown air and a heat medium;   a target temperature setup device that sets a target temperature (Tset) for a passenger compartment in accordance with an operation performed by an occupant; and   a control device that determines the availability factor of the blower in accordance with the temperature of the heat medium,   wherein the control device increases the availability factor of the blower as the target temperature (Tset) increases.   
     
     
         2 . The air conditioner according to  claim 1 , further comprising:
 a power saving request device for outputting a power saving request signal in accordance with an operation of the occupant to request that the power required for air conditioning in the passenger compartment be saved,   wherein, when the power saving request signal is output, the control device increases the availability factor of the blower as the target temperature (Tset) increases.   
     
     
         3 . The air conditioner according to  claim 2 , wherein the control device causes the blower to operate at a lower availability factor when the power saving request signal is output than when the power saving request signal is not output.
