Abstract
PURPOSE: To make cool or warm air from an inside fan comfortable, by adjusting the conversion range of a frequency converter for power to a motor of a compressor depending on a value set by a speed setting unit provided for the inside fan whose speed can be shifted.
CONSTITUTION: A detector 4 of a bridge circuit varies the outut voltage of diodes C1WD3 depending on the difference ΔT between the room temperature T detected by a detecting element 21 of a room temperature detector and a temperature To set by a room temperature setting unit 3. When the air conditioner is operating at a point B1 on a conversion line A1 and a user feels cold, changeover switches r1Wr3 are shifted to change the conversion line from A1 to A2. At that time, the output frequency of the frequency converter decreases to a value corresponding to a point B2 at which the temperature difference ΔT is ΔT1. The output frequency increases and balances according as the capacity of the compressor and the quantity of the air from the fan decrease. Excessive cooling is thus prevented at a temperature difference value ΔT2.
