Problems solved by technology

[0002] Generally, setting an intermediate heat exchanger in a heat pump system can improve the performance of the heat pump system. For example, the intermediate heat exchanger can improve the cooling performance of the heat pump system, but when the heat pump system is heating, the intermediate heat exchanger increases the compressor's suction flow rate. heat, which may lead to a reduction in the performance of the heat pump, therefore, it is necessary to improve the existing technology to help improve the performance of the thermal management system

Embodiment 1

[0028] like Figure 1-Figure 5 As shown, this embodiment provides a heat pump system, which has multiple working modes such as cooling mode, heating mode and dehumidification mode (or demisting mode). Specifically, the heat pump system includes an air conditioning box for adjusting the temperature and / or humidity in the compartment, and the heat pump system also includes a compressor 1, a gas-liquid separator 2, a third heat exchanger 5 and an intermediate heat exchanger 6; An air duct is arranged inside the box, and one end of the air duct is provided with a first damper 14 for introducing circulating air into the air duct, and the other end of the air duct is provided with a grille 15 for supplying air to the compartment. The fan 16, the second heat exchanger 4 and the first heat exchanger 3 are arranged in sequence from the inlet to the outlet, wherein the air inlet side of the first heat exchanger is provided with a second damper 17 for controlling the flow through the fir...

Embodiment 2

[0042] like Figure 5 As shown, this embodiment provides another heat pump system, which is basically the same in composition and working principle as the heat pump system in Embodiment 1, the difference is that the first heat exchanger 3 and / or the second heat exchanger in this embodiment Device 4 is not arranged in the air duct. Specifically, the first heat exchanger 3 in this embodiment may include a refrigerant flow channel and a cooling liquid flow channel, and the refrigerant flow channel of the first heat exchanger 3 and the cooling liquid flow channel of the first heat exchanger 3 are relatively disconnected. , the refrigerant in the refrigerant flow path of the first heat exchanger 3 and the coolant in the coolant flow path of the first heat exchanger 3 can perform heat exchange; further, the heat pump system also includes a fourth heat exchanger 19 and a fourth heat exchanger 19 A pump 20 , through which the coolant channel of the first heat exchanger 3 communicates...

Embodiment 3

[0044] like Figure 6-Figure 11 As shown, this embodiment provides another heat pump system, which is basically the same in structure and working principle as that of the heat pump system in Embodiment 1, the difference is that a first fluid switching valve 18 is provided in this embodiment, such as Figure 10 and Figure 11 As shown, the first fluid switching valve 18 has four ports, which are respectively the first port 181 of the first fluid switching valve, the second port 182 of the first fluid switching valve, the third port 183 of the first fluid switching valve and The fourth port 184 of the first fluid switching valve. The working mode of the first fluid switching valve 18 is different from that of the conventional four-way valve, and it includes a first working mode and a second working mode, such as Figure 10 As shown, in the first working mode of the first fluid switching valve 18, the third port 183 of the first fluid switching valve communicates with the first...
