Abstract (en)

A heat exchanger comprises a heat transfer part that exchanges heat between an air-conditioning air and a heat exchanging medium, and a control device that adjusts a heat exchange amount between the air-conditioning air and the heat exchanging medium. The heat transfer part includes a flow dividing circuit configured to divide a heat transfer pipe group through which the heat exchanging medium flows into a plurality of groups and cause grouping ratios to be different from each other, and the control device is configured to increase or decrease a flow rate of the heat exchanging medium in a first group having a smaller grouping ratio among the plurality of groups in a case of a low air conditioning load.
