Abstract: The seat air conditioner configured to supply conditioning air to a seat in a vehicle cabin includes a refrigeration cycle, an air blower, and a conditioning air supply unit. The refrigeration cycle includes a compressor that compresses and discharges a refrigerant, a heat emitting portion that emits heat of the refrigerant discharged from the compressor to generate a warm air, a decompressor that decompresses the refrigerant flowing out of the heat emitting portion, and a heat absorbing portion that evaporates the refrigerant decompressed by the decompressor to generate a cold air. The air blower blows air to exchange heat with the refrigerant. The conditioning air supply unit supplies each of the warm air generated by the heat emitting portion and the cold air generated by the heat absorbing portion as the conditioning air to the seat.

Abstract: A cold storage heat exchanger has refrigerant pipes fins, and cold-storage-medium containers. The cold-storage-medium container is arranged next to the refrigerant pipe. A cold storage medium is accommodated in the cold-storage-medium container in order to leave an air cell, and to provide a filling ratio of less than 90%. The cold-storage-medium container has a plurality of depressions at an inside of the cold-storage-medium container. The depression is a dimple. The plurality of depressions are joined each other at top parts and provide high rigidity. The cold-storage-medium container is positioned on the refrigerant pipe by an engaging projection. An open end of an open depression is covered by the refrigerant pipe. The cold storage medium can flow into the open depression. Therefore, the cold storage medium may directly contact the refrigerant pipe, and is directly cooled with the refrigerant.

Abstract: A cold storage heat exchanger has: refrigerant pipes each of which has a refrigerant passage therein, the refrigerant pipes arranged to be distanced from each other with clearances therebetween; and a cold storage material disposed in at least one of the clearances. At least an another one of the clearances provides an air passage. The heat storage material is disposed in at least two of the clearances arranged adjacent to each other. A refrigerant pipe pitch between two of the refrigerant pipes that are adjacent to each other and therebetween have the cold storage material is shorter than a refrigerant pipe pitch between two of the refrigerant pipes that are adjacent to each other and therebetween have the air passage. Thus, a time duration required for a cold storage can be shortened.

Abstract: A refrigerant evaporator has an interchange part. The interchange part connects a first collecting part of a second downstream tank part, and a second distribution part of a second upstream tank part. The interchange part connects a second collecting part of a second downstream tank part, and a first distribution part of a second upstream tank part. The interchange part swaps a refrigerant about a width direction of a core. Refrigerant passages relevant to the interchange part are configured to improve refrigerant distribution. Providing a plurality of passages and/or twisting a passage improve distribution.
