[ example 1]
The basic implementation in this example is as follows:
the present embodiment relates to a humidification system, including: and the water receiving disc is arranged on an air supply flow path below the heat exchanger in the heat pump air conditioner, and the air supply power of the air supply flow path is from an air supply fan of the indoor heat exchanger. When the indoor unit of the heat pump air conditioner operates in a refrigerating mode, condensed water generated by the indoor heat exchanger is collected into the water receiving disc, the condensed water of the water receiving disc is continuously evaporated in the air supply flow path, and atomized steam generated by evaporation is taken away by air flow of the air supply flow path and is sent out through the air supply opening of the air conditioner. The humidifying system also comprises a heat exchange tube which is thermally coupled with the water pan, the heat exchange tube is led to the air-conditioning indoor unit of the heat pump, and the heat exchange tube has the function of a condenser when the air-conditioning indoor unit is in heating operation and releases heat to the water pan.
Further optionally, the branch where the heat exchange tube is located and the branch where the air-conditioning indoor heat exchanger is located are in series or parallel relation. When the branch of the heat exchange tube and the branch of the indoor heat exchanger are in parallel connection, the branch of the heat exchange tube and the branch of the indoor heat exchanger are respectively provided with an electromagnetic valve. When the branch where the heat exchange tube is located and the branch where the indoor heat exchanger is located are in series connection, the branch where the heat exchange tube is located is arranged at the outlet end of the branch where the indoor heat exchanger is located.
Preferably, the branch of the heat exchange tube is in parallel connection with the branch of the indoor heat exchanger. The reason for this is that: when the branch where the heat exchange tube is located is in parallel connection with the branch where the indoor heat exchanger is located, when the heat pump air conditioner carries out refrigeration 1, the electromagnetic valves of all the branches can control the refrigerant to only pass through the indoor heat exchanger but not pass through the branch where the heat exchange tube is located, so that the refrigeration effect of the indoor heat exchanger cannot be reduced;
2. when the heat pump air conditioner heats, the electromagnetic valves of all branches can control the refrigerant to pass through the branch where the heat exchange tube is located instead of the indoor machine exchanger, so that all heat generated during heating can be absorbed by condensed water in the water receiving box, and the time for transferring the air conditioner to heat can be effectively shortened.
When the branch where the heat exchange tube is located and the branch where the indoor heat exchanger is located are in a series relation: 1. when the heat pump air conditioner performs refrigeration, the heat exchanger of the indoor unit and the branch where the heat exchange pipe is located are in a loop, and the cold energy generated by the refrigeration of the branch where the heat exchange pipe is located cannot be timely sent into a room by the fan of the indoor unit, so that the power consumption of the air conditioner is increased compared with the situation of parallel arrangement;

The heat exchange tube comprises a plurality of straight tube sections which are arranged in parallel, and the plurality of straight tube sections are connected in series through a plurality of bent tube sections. The whole heat exchange tube 3 makes a round trip to buckle and sets up in the water collector 4 promptly, and the foretell useful effect of setting up mode of heat exchange tube lies in the area of contact of increase heat exchange tube and water collector in this implementation, prolongs the time that the refrigerant flowed through the heat exchange tube to reach the effect of increase heat transfer pipeline heat release.

The heat exchange tube 3 is arranged at the bottom of the water pan 4 and can be fixed at the bottom of the water pan through the limiting component. The beneficial effects are that: the heat pump air conditioner can be prevented from generating abnormal sound due to the shaking of the heat exchange tube when the heat pump air conditioner works, the product experience of a user in using the air conditioner is influenced, and meanwhile, the heat exchange tube is in direct contact with condensed water accumulated in the water pan, so that the heat absorption and evaporation process of the condensed water is facilitated.
