[0041] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0042] Example 1 is a schematic diagram of the control mode of the electric drive source heat pump of the utility model;

[0043] Refrigeration module: see Figure 1 In the middle black dotted line circuit, the plate-type water-cooled evaporator 4 absorbs the waste heat of the electric drive and electronic control 15 on the coolant side through the low-temperature electronic water pump 12 circulation. The refrigerant side of the plate-type water-cooled evaporator 4 changes from a low-temperature and low-pressure liquid to a low-temperature and low-pressure gas, which is compressed by the compressor 1 and becomes a high-temperature and high-pressure gas. The high-temperature heat is then transferred to the antifreeze liquid through the plate-type water-cooled condenser 2, and the refrigerant side becomes a medium-temperature and high-pressure liquid. It is throttled by the first electronic expansion valve 3 to become a low-temperature and low-pressure liquid and returns to the plate-type water-cooled evaporator 4.

[0044] Low temperature cooling module: see Figure 1 The left black dotted line loop circulates through the low-temperature electronic water pump 12 through the coolant side of the plate-type water-cooled evaporator 4, the four-way valve A (1-2), the three-way valve E (1-3), the electric drive and electronic control 15, the four-way valve B (1-2), and then to the low-temperature electronic water pump 12, transferring the heat of the electric drive and electronic control 15 to the plate-type water-cooled evaporator 4; when the electric drive and electronic control 15 has too much heat, the three-way valve E (2-3) is used to adjust the heat and transfer it to the low-temperature radiator 13, and then the electronic fan 14 discharges the heat to the air outside the vehicle.

[0045] High temperature heating module: see Figure 1The solid black line circuit on the right circulates through the high-temperature electronic water pump 5 through the coolant side of the plate-type water-cooled condenser 2 and the three-way valve D (1-3) to transfer one path of heat to the heater core 7. The cold air exchanges heat with the heater core 7 through the blower 9 to transfer the heat to the passenger compartment to meet the heating demand of the passenger compartment; the other path of heat passes through the three-way valve D (1-2), the four-way valve A (3-4), and the three-way valve C (1-3) to transfer the heat to the battery for heating to meet the battery heating demand.

[0047] Refrigeration module: see Figure 2 In the middle black dotted line loop, the plate-type water-cooled evaporator 4 absorbs the waste heat of the electric drive and electronic control 15 on the coolant side through the low-temperature electronic water pump 12 circulation. The refrigerant side of the plate-type water-cooled evaporator 4 changes from low-temperature and low-pressure liquid to low-temperature and low-pressure gas, which is compressed by the compressor 1 and becomes high-temperature and high-pressure gas. The high-temperature heat is then transferred to the antifreeze liquid through the plate-type water-cooled condenser 2, and the refrigerant side becomes medium-temperature and high-pressure liquid. After throttling by the first electronic expansion valve 3, it becomes low-temperature and low-pressure liquid and returns to the plate-type evaporator 4. When the waste heat of the electric drive is insufficient, the inlet temperature pressure PT2 of the compressor 1 will be too low. At this time, the second electronic expansion valve 17 needs to be opened to increase the pressure of PT2 to ensure the stable operation of the compressor.

[0048] Low temperature cooling module: see Figure 2 The left black dotted line loop circulates through the low-temperature electronic water pump 12 through the coolant side of the plate-type water-cooled evaporator 4, the four-way valve A (1-2), and the three-way valve E (1-3) to transfer the heat of the electric drive and electronic control to the plate-type water-cooled evaporator 4; when the heat of the electric drive and electronic control is too much, the heat is transferred to the low-temperature radiator 13 through the three-way valve E (1-2), and then the heat is discharged to the air outside the vehicle through the electronic fan 14.

[0049] High temperature heating module: see Figure 2 The solid black line circuit on the right circulates through the high-temperature electronic water pump 5 through the coolant side of the plate-type water-cooled condenser 2 and the three-way valve D (1-3) to transfer one path of heat to the heater core 7. The cold air exchanges heat with the heater core 7 through the blower 9 to transfer the heat to the passenger compartment to meet the heating demand of the passenger compartment; the other path of heat passes through the four-way valve A (3-4) and the three-way valve C (1-3) to transfer the heat to the battery for heating to meet the heating demand of the battery.

[0052] Low temperature cooling module: see Figure 3 The left black dotted line loop circulates through the low-temperature electronic water pump 12 through the coolant side of the plate-type water-cooled evaporator 4 and the four-way valve A (1-2) to the low-temperature radiator 13, absorbs the low-temperature heat of the air through the low-temperature radiator 13 and the electronic fan 14, and transfers the heat to the refrigerant side of the water-cooled evaporator 4 through the three-way valve E (2-3), the four-way valve B (1-2), and the low-temperature electronic water pump 12.

[0053] High temperature heating module: see Figure 3 The solid black line circuit on the right circulates through the high-temperature electronic water pump 5 through the coolant side of the plate-type water-cooled condenser 2, PTC 6, and three-way valve D (1-3), transferring one path of heat to the heater core 7.

[0054] Example 4: is a schematic diagram of the battery source heat pump control mode of the utility model;

[0055] Refrigeration module: see Figure 4 In the middle black dotted line circuit, the plate-type water-cooled evaporator 4 absorbs the heat of the battery 10 on the coolant side through the low-temperature electronic water pump 12 circulation, and the refrigerant side of the plate-type water-cooled evaporator 4 changes from a low-temperature and low-pressure liquid to a low-temperature and low-pressure gas; after being compressed by the compressor 1, it becomes a high-temperature and high-pressure gas, and then the high-temperature heat is transferred to the antifreeze liquid through the plate-type water-cooled condenser 2, and the refrigerant side becomes a medium-temperature and high-pressure liquid, which is throttled by the first electronic expansion valve 3 to become a low-temperature and low-pressure liquid and returns to the plate-type evaporator 4.
