An indoor unit includes a casing having a suction port formed on an upper portion and a blow-out port on a lower side of a front surface portion, an axial-flow or mixed-flow fan provided on the downstream side of the suction port in the casing, and a heat exchanger provided in the casing at a position on the downstream side of the fan and on the upstream side of the blow-out port. The heat exchanger includes a plurality of fins arranged side by side with predetermined gaps therebetween and a plurality of heat-transfer tubes penetrating through the plurality of fins. The heat exchanger is configured in such a manner that the air-flow resistance of an area facing the outer peripheral side of the fan is larger than the air-flow resistance of an area facing a center portion of the fan.

An indoor unit of an air-conditioning apparatus is provided, in which an air-conditioning condition changed based on a gesture corresponds to an air-conditioning condition displayed on a display device of a remote controller. With an indoor unit 100, when a user U1 performs a predetermined motion (S1-1), a controller 70 determines the motion of the user U1 (S1-2), recognizes that a gesture instruction condition is instructed (S1-3), controls a heat exchanger 4 and other devices based on the gesture instruction signal (S1-4), and causes the gesture instruction signal to be sent to a remote-controller communication device 85 (S1-5). When a remote controller 80 receives the gesture instruction signal (S1-6), the gesture instruction condition is displayed on a remote-controller display device 82 (S1-7), and buzzer sound (electronic beeper sound) is output from a remote-controller sound output device 83 (S1-8).

When a user thinks “Is it a malfunction?” and wants to relieve this doubt and worry, the user first pushes a menu button 83b on the remote control 80 and further pushes a minus button 83c or a plus button 83a to set the cursor on the “In a case such as . . . (inquiry menu)”. Here, when the set button 83e is pushed, two menu items, namely, “During heating operation . . . ” and “From the outdoor unit . . . ” are displayed. Further, when the set button 83e is pushed while the cursor is set to the “During heating operation . . . ”, “The horizontal flaps will be in a horizontal state at the start of operation, during defrosting, and when temperature has become above the set temperature. It is not a malfunction” is displayed on the display unit 82.

In a delta-sigma A/D converter provided with plural channels for converting an analog input signal into a digital signal, an adverse influence of an idle tone is reduced in each channel. The delta-sigma A/D converter comprises: a first quantizer which quantizes and outputs a received signal; a first D/A converter which converts an output signal of the first quantizer into an analog signal, and outputs the converted analog signal; a first operation unit which outputs a signal indicative of a difference of the first analog input signal and an output signal of the first D/A converter; a first integrator which integrates an output signal of the first operation unit and outputs the integrated signal; a first dither circuit which generates a first dither signal; and a second operation unit which adds the first dither signal to the output signal of the first integrator and outputs the added signal to the first quantizer.
