A heat exchanger includes a heat exchange tube () and a first water collecting tank (). The first water collecting tank () is provided on the heat exchange tube (), a first water diversion hole () is provided at a bottom portion of the first water collecting tank (), the heat exchange tube () passes through the first water diversion hole (), and the first water diversion hole () has a diameter greater than an outer diameter of the heat exchange tube (). By providing the first water collecting tank (), and making the heat exchange tube () pass through the first water diversion hole () provided on the first water collecting tank (), and leaving a gap between the heat exchange tube () and the first water diversion hole (), the water in the first water collecting tank () evenly flows into the first water diversion hole ().

Heat exchanger, air conditioner, and refrigerating unit

Provided are a control method of a heat pump system and a heat pump system. The heat pump system includes a throttling element and a four-way valve. The four-way valve has a first state in a case that the heat pump system operates for refrigerating and a second state in a case that the heat pump system operates for heating. The control method includes that: before the four-way valve is switched from the first state to the second state, A is compared with B, and switching of the state of the four-way valve is controlled and the opening degree of the throttling element is adjusted according to the comparison result, or switching of the state of the four-way valve is controlled according to the comparison result, or the opening degree of the throttling element is adjusted according to the comparison result.
