Abstract
An air conditioning apparatusincludes a compressor (), an indoor heat exchanger () that is a use-side heat exchanger that exchanges heat with first air (F), an outdoor heat exchanger () that is a heat-source-side heat exchanger that exchanges heat with second air, a refrigerant, a first duct (), and a casing (). The refrigerant contains at least 1,2-difluoroethylene, and circulates in the compressor (), the indoor heat exchanger (), and the outdoor heat exchanger () to repeat a refrigeration cycle. The first duct () supplies the first air (F) to a plurality of rooms in an interior. The casing () includes a use-side space (SP) that is connected to the first duct () and that accommodates the indoor heat exchanger (). The casing () is configured to allow the first air (F) after heat exchange with the refrigerant at the indoor heat exchanger () to be sent out to the first duct ().
