Abstract: An air conditioner is disposed with a casing, a filter, an indoor heat exchanger, a blower, and a blowout passage. The casing includes a suction opening and a blowout opening. The filter is disposed downstream of the suction opening and transmits air. The indoor heat exchanger is disposed facing the filter downstream of the filter and performs heat exchange with air that passes through the indoor heat exchanger. The blower is disposed downstream of the indoor heat exchanger and generates a flow of air that is sucked in from the suction opening and is blown out from the blowout opening. The blowout passage includes an air introduction opening disposed facing and downstream of the indoor heat exchanger and guides air from the air introduction opening to the blowout opening. Additionally, the filter has an outer shape that is slanted with respect to the indoor heat exchanger.

Abstract: An air conditioner executes a heating operation using at least a high pressure refrigerant, and includes a refrigerant circuit configured to execute a vapor compression refrigeration cycle. The refrigerant circuit includes a convective heat exchanger, a radiant heat exchanger, an open/close valve and a check valve. The convective heat exchanger executes heat exchange between the high pressure refrigerant flowing inside and an air flowing towards outside. The radiant heat exchanger heats a predetermined member using the high pressure refrigerant flowing inside to cause the predetermined member to emit a radiant heat. The open/close valve is disposed upstream of the radiant heat exchanger in order to block a flow path of the high pressure refrigerant flowing towards the radiant heat exchanger during the heating operation. The check valve is disposed between the radiant heat exchanger and the open/close valve.

Abstract: An indoor unit of an air conditioner includes an indoor heat exchanger, a body, a centrifugal fan, and a shutter. A plurality of discharge passages for discharging air that has passed through the indoor heat exchanger is formed in the body. The centrifugal fan generates a flow of air that passes through the indoor heat exchanger and is blown out of the discharge passages. The shutter is provided to at least one discharge passage of the plurality of discharge passages. The shutter is kept in a closed state by the pressure of the air flow.

Abstract: The indoor unit comprises a body and a cover member. The body has a rear ledge. The rear ledge can be embedded in a wall. The cover member has a plurality of cover elements. The plurality of cover elements is aligned along the direction in which the rear ledge is embedded in a wall. The plurality of cover elements can be partitioned. The cover member covers at least part of the rear ledge.
