摘要： There is disclosed a ceiling embedded type indoor unit which is reduced in height to provide a compact unit body size and which provides a large cooling/heating capability. The ceiling embedded type indoor unit comprising two air blowoff ports and embedded in a ceiling comprises a heat exchanger formed in a U-shape with sides of the U-shape being disposed on long sides of a unit body and connected to a header pipe for circulating a coolant at one end of an open side of the U-shape, air blowoff ports disposed to extend from a bottom side the U-shape, and a centrifugal blower disposed aside to the bottom side of the U-shape relative to a substantial center of a length direction of the sides of the U-shape.

摘要： In a ceiling embedded indoor unit for an air conditioner, blower noise is prevented while maintaining a high air conditioning capacity. The ceiling embedded indoor unit is provided with a U-shaped heat exchanger placed in a casing embedded in a ceiling. The U-shaped heat exchanger includes two side portions, a portion connecting the side portions at one end, and blowers arranged in an inner space of the heat exchanger. A decorative panel is mounted to a lower surface of the casing that has two elongated air outlet ports in correspondence to the side portions of the heat exchanger and an air suction port formed between the air outlet ports. A control apparatus controls the number of rotations of the blower near the valley portion of the U-shaped heat exchanger to be higher than the blower near the open end.

摘要： In a ceiling embedded type indoor unit for an air conditioner, an wind sound is reduced while preventing a beat sound of blowers with keeping a high air conditioning capacity. In the ceiling embedded type indoor unit provided with a U-shaped heat exchanger which is placed in a casing embedded in a ceiling and is constituted by two side portions and a bottom portion connecting the side portions at one end side, blowers arranged in an inner space of the heat exchanger, a decorative panel mounted to a lower surface of the casing and having two elongated air outlet ports in correspondence to the side portions of the heat exchanger and an air suction port formed between the air outlet ports, and a control apparatus, the control apparatus controls so that the number of rotation of the blower near a valley portion of the U-shaped heat exchanger becomes high and the number of rotation of the blower near the open end of the U-shaped heat exchanger becomes low.
