<p>PURPOSE:To prevent fuel consumption from reduction by providing a capacity altering means of a variable capacity compressor which controllably provides a preset idle rotational frequency in the detection of idling condition. CONSTITUTION:When a change lever 24 is set to the neutral position and an engine 1 is set to the idling condition, a calculation controller 17 sets a predetermined rotational frequency of engine for idling and then controllably drives an electromagnetic valve 11 of a variable capacity compressor on the basis of rotational frequency of engine detected by an idle rotational frequency detector 22 to control the capacity of said compressor. That is, the capacity control is not performed by blow-off air temperature Tf and temperature Tc set by a desired temperature setting switch 20, but the compression capacity is controlled to provide the idle rotational frequency set by the rotational frequency of engine.</p> |
