Abstract
An air conditioning system includes an indoor heat exchanger, an outdoor heat exchanger, an economizer, and an electric control box: the economizer is disposed between the indoor heat exchanger and the outdoor heat exchanger; the economizer includes a heat exchange body; the heat exchange body is provided with a plurality of first micro-passages for a first refrigerant flow and a plurality of second micro-passages for a second refrigerant flow; the second refrigerant flow absorbs heat from the first refrigerant flow so that the first refrigerant flow is subcooled, or the first refrigerant flow absorbs heat from the second refrigerant flow so that the second refrigerant flow is subcooled, the economizer is further configured to dissipate heat for an electronic component in the electric control box.
