Abstract
An air conditioning apparatus for a railway vehicle includes a compressor to compress a refrigerant, a condenser to condense the compressed refrigerant, an expander to expand the condensed refrigerant, an evaporator to vaporize the expanded refrigerant, and refrigerant piping connecting the compressor, the condenser, the expander, and the evaporator. One of the condenser or the evaporator is an indoor heat exchanger, and the other is an outdoor heat exchanger. At least one of the outdoor heat exchanger or the indoor heat exchanger includes a body including planar heat-transfer members and fins alternately stacked in a thickness direction of the planar heat-transfer members so as to have a stacked structure. Each planar heat-transfer member includes at an interior thereof refrigerant flow paths for flow therethrough of the refrigerant. The refrigerant flow paths are arranged in a direction in which air passes through the fins.
