Air conditioning device

Abstract

To disclose one example of an air conditioner which can suppress the occurrence of hunting which is caused by non-convergence of control of freezing capacity occurring in an evaporator.SOLUTION: An air conditioner comprises: a fan control unit 6B for controlling a blow volume of a blower 5A between a maximum blow volume and a minimum blow volume so that a detected temperature of a blowout-side temperature sensor 7B is a preset blowout set temperature; and a minimum blow volume change unit 6C for changing a magnitude of the minimum blowout volume according to a measured temperature. When a variation in the measured temperature within a preset time is larger than a preset threshold, the minimum blow volume change unit 6C increases a magnitude of the minimum blow volume compared with that at the current time. As a result, in the air conditioner 1, when a measured variation width is large, a variation width of the blow volume also becomes large. Therefore, when the variation width of the blow volume becomes small, a variation width of capacity in capacity control can also become small. In turn, it is prevented that control of freezing capacity does not converge and hunting occurs.SELECTED DRAWING: Figure 1
