Abstract: A blower includes a fan that has blades and generates an air flow by rotating. Each of the blades has a front edge and a serration provided at least in a part of the front edge. The serration has tip portions and recessed portions arranged alternately with each other. Each of the blades has a negative pressure surface and one or more ribs protruding from the negative pressure surface. Each of the ribs extends from a corresponding one of the recessed portions, which is designated as a starting point, toward a rear edge of a corresponding one of the blades.

Abstract: A refrigeration cycle device includes: a variable displacement compressor including a discharge capacity varying part to change a refrigerant discharge capacity; a controller that outputs a capacity control signal to the variable displacement compressor to change the refrigerant discharge capacity; a heat exchanger that condenses or cools refrigerant discharged from the variable displacement compressor; a decompressor that decompresses and expands refrigerant flowing out of the heat exchanger; an evaporator that evaporates refrigerant decompressed and expanded by the decompressor; and a high load determiner that determines whether the compressor is in a high load operational status based on the capacity control signal.
