Problems solved by technology
[0002] At present, the technology of heat pump water heaters and heat pump hot water air conditioners is mature and widely used. Most of the heat pump water tanks are a water tank with an insulation layer and a coil heat exchanger installed in the water tank. When hot water is urgently needed Hot water cannot be provided at all times, and if the water temperature is kept high for a long time, it is easy to cause loss of heat energy. For example, when it is applied to a heat pump hot water air conditioner unit, the value of heat energy recovery of the air conditioner during cooling is lost due to the frequent maintenance of high water temperature. There are also some heat pumps Type direct heating heat exchanger, in the application, the problem of combination and conversion of direct heating and full tank water heating mode is not well solved, and the problem of heat energy recovery of air conditioner during cooling

Embodiment Construction
[0012] figure 1 It is a three-way differential pressure automatic diverter valve according to the embodiment of the present invention. The connection port 101 is connected to the water outlet pipe 5, the connection port 102 is connected to the casing of the casing heat exchanger 13, and the connection port 103 is connected to the water storage tank. 8 connection, the return spring 105 and the movable spool 106 are installed in the valve body 104; when the water is used, the pressure of the connecting port 101 is lower than the pressure of the connecting ports 102 and 103, so that the movable spool generates the power to connect with the connecting port 101, When the connection ports 101 and 102 are connected, the connection port 103 is cut off by a special spool. When there is no water, the pressure between the connection ports is equalized through the gap between the movable spool 106 and the valve body 104, and the valve is closed by the return spring. The core returns to it...

The invention aims to provide a heat pump type hot water tank applied to a heat pump hot water air conditioning unit. The heat pump type hot water tank comprises a storage tank, a double-pipe heat exchanger, a coiled pipe heat exchanger and a three-way differential pressure automatic converter valve, wherein the double-pipe heat exchanger is arranged in the insulating layer of the water storage tank; the coil pipe heat exchanger is arranged in a water storage barrel; the heating of heat pump type hot water tank when using water or using no water can be automatically switched into two modes of heating of the whole tank water or direct heating by the three-way differential pressure automatic converter valve, thereby providing hot water in a direct heat mode under special condition, realizing providing hot water continually and avoiding the fact that the hot water tank can be used only when all water in the tank is heated, and the fact that the temperature of the water tank is always kept high, which causes natural loss of heat energy and loss of the value of the heat energy recycle during refrigeration of the air conditioner.
