摘要： PROBLEM TO BE SOLVED: To provide an indoor unit of an air conditioner capable of achieving high heat exchanging performance by combining a substantially square heat exchanger and a substantially rectangular air outlet, and reducing ventilation resistance.SOLUTION: A substantially rectangular air outlet arranged in parallel with a linear region of a heat exchanger is disposed on a position closer to a rotational inlet side of a fan in the linear region. Since the air outlet having a length determined to obtain a prescribed wind velocity, is positioned closer to the rotational inlet side of the fan having high wind velocity, the air can be blown out from the air outlet with high efficiency while reducing ventilation resistance. As a result, an indoor unit can contribute to energy saving of an air conditioner.

摘要： PROBLEM TO BE SOLVED: To determine a frost formation state of a heat exchanger.SOLUTION: A control device of an outdoor unit holds a PQ characteristic indicating a characteristic of a static pressure and a fan air flow of an outdoor fan every fan number-of-revolutions (S1). The control device estimates the fan air flow based on the PQ characteristic corresponding to the fan number-of-revolutions and an air pressure of an air exit side of an outdoor heat exchanger (S2). The control device calculates a resistance coefficient based on the estimated fan air flow and air pressure (S3), and estimates a frost formation state of the outdoor heat exchanger by comparing the calculated resistance coefficient with a standard resistance coefficient used when frost does not stick to the outdoor heat exchanger (S4). The control device performs defrosting operation to remove the frost stuck to the outdoor heat exchanger when the control device determines that frost sticks to the outdoor heat exchanger.
