In at least one cooling water circulation loop in the plurality of cooling water circulation loops, cooling water flows through the condenser 102 and the warm air core 103 in sequence, and heat generated by the condenser is absorbed by the cooling water and reaches the warm air core to provide a heat source for the warm air core. Therefore, the PTC heater is not needed to work, the heat of the refrigerant in the condenser is used for providing a heat source for the warm air core, and the purpose of heating the air conditioning system and simultaneously not influencing the endurance mileage of the vehicle as far as possible is achieved.

The cooling water is driven by the first cooling water pump 101, flows into the condenser 102 through the D port of the four-way valve 104 and the C port of the four-way valve 104, the heat of the refrigerant in the condenser 102 is absorbed by the cooling water flowing into the condenser 102, and the cooling water after absorbing the heat flows through the first adjustable one-way valve 1062, the B port of the four-way valve 104 and the a port of the four-way valve 104 in sequence, reaches the warm air core 103, and provides a heat source for the warm air core 103.
It can be seen that in the first cooling water circulation loop, the PTC heater is not required to operate, but the heat of the refrigerant in the condenser 102 is used to provide a heat source for the warm air core 103, so as to achieve the purpose of heating the air conditioning system while minimizing the influence on the driving range of the vehicle.
Next, the second cooling water circulation circuit will be explained.
Referring to fig. 1, a first cooling water pump 101, a D port of a four-way valve 104, a C port of the four-way valve 104, a condenser 102, an adjustable valve 106, a radiator 105, a B port of the four-way valve 104, an a port of the four-way valve 104, and a warm air core 103 are connected in series in this order to form a second cooling water circulation circuit. The cooling water flows into the condenser 102 through the port D of the four-way valve 104 and the port C of the four-way valve 104 under the driving of the first cooling water pump 101, the heat of the refrigerant in the condenser 102 is absorbed by the cooling water flowing into the condenser 102, the cooling water after absorbing the heat flows through the adjustable valve 106 and the radiator 105 in sequence, the radiator 105 radiates the cooling water after absorbing the heat, and the cooling water after radiating the heat flows into the port B of the four-way valve 104 and the port a of the four-way valve 104 again and then reaches the warm air core 103 to provide a heat source for the warm air core 103.
Referring to fig. 2, a first cooling water pump 101, a D port of a four-way valve 104, a C port of the four-way valve 104, a condenser 102, a C port of an adjustable three-way valve 1061, a B port of the adjustable three-way valve 1061, a radiator 105, a B port of the four-way valve 104, an a port of the four-way valve 104, and a warm air core 103 are connected in series in this order to form a second cooling water circulation circuit. The cooling water is driven by the first cooling water pump 101 to flow into the condenser 102 through the D port of the four-way valve 104 and the C port of the four-way valve 104, the heat of the refrigerant in the condenser 102 is absorbed by the cooling water flowing into the condenser 102, the cooling water after absorbing the heat flows through the C port of the adjustable three-way valve 1061, the B port of the adjustable three-way valve 1061 and the radiator 105 in sequence, the radiator 105 radiates the cooling water after absorbing the heat, and the cooling water after radiating the heat flows into the B port of the four-way valve 104 and the a port of the four-way valve 104 to reach the warm air core 103, so as to provide a heat source for the warm air core 103.
Referring to fig. 3, a first cooling water pump 101, a port D of a four-way valve 104, a port C of the four-way valve 104, a condenser 102, a second adjustable one-way valve 1063, a radiator 105, a port B of the four-way valve 104, a port a of the four-way valve 104, and a warm air core 103 are connected in series in this order to form a second cooling water circulation circuit. The cooling water flows into the condenser 102 through the D port of the four-way valve 104 and the C port of the four-way valve 104 under the driving of the first cooling water pump 101, the heat of the refrigerant in the condenser 102 is absorbed by the cooling water flowing into the condenser 102, the cooling water after absorbing the heat flows through the second adjustable one-way valve 1063 and the radiator 105 in sequence, the radiator 105 radiates the heat of the cooling water after absorbing the heat, and the cooling water after radiating the heat flows into the B port of the four-way valve 104 and the a port of the four-way valve 104 and then reaches the warm air core 103 to provide a heat source for the warm air core 103.
In the second cooling water circulation loop, the PTC heater is not needed to work, the heat of the refrigerant in the condenser 102 is divided into two parts, one part of the heat is radiated by the radiator 105, and the other part of the heat provides a heat source for the warm air core body 103, so that the purpose of heating the air conditioning system and simultaneously not influencing the endurance mileage of the vehicle as far as possible is realized.
Therefore, by adopting the cooling system provided by the embodiment of the disclosure, the heat of the refrigerant in the condenser can be fully utilized, and the heat source is provided for the warm air core body by utilizing the whole heat or part of the heat of the refrigerant in the condenser. The PTC heater is not needed to work, and the purpose that the driving range of the vehicle is not influenced as much as possible while the air conditioning system is heated is achieved.
Alternatively, as shown in fig. 1 to 3, the cooling system 100 includes, in addition to the first cooling water pump 101, the condenser 102, the warm air core 103, the four-way valve 104, the radiator 105, and the adjustable valve 106: the compressor 107 and the evaporator 108, and the compressor 107, the evaporator 108, and the condenser 102 are connected in series in this order to form a refrigerant circulation circuit. In fig. 1 to 3, the refrigerant circulation circuit is shown by a broken line. The compressor 107 draws gaseous refrigerant from the evaporator 108 and drives the gaseous refrigerant into the condenser 102, where the cooling water condenses the gaseous refrigerant into liquid refrigerant in the condenser 102, which reenters the evaporator 108 and absorbs heat from the air flowing through the evaporator 108 to evaporate the liquid refrigerant into gaseous refrigerant, so that the compressor 107 draws the gaseous refrigerant from the evaporator 108.
In the evaporator 108, the liquid refrigerant absorbs heat of air flowing through the evaporator 108 and evaporates into gaseous refrigerant, so that the air at the evaporator 108 is cooled down to realize refrigeration, after the gaseous refrigerant enters the condenser 102, heat in the gaseous refrigerant is absorbed by cooling water, the cooling water after absorbing heat flows through the first cooling water circulation loop or the second cooling water circulation loop, and finally heat in the gaseous refrigerant is used as a heat source of the warm air core 103 to realize heating.
Since the cooling system 100 including the compressor 107 and the evaporator 108 can cool and heat, comfortable in-vehicle temperature can be provided for the occupant, and the use experience of the occupant is improved.
Alternatively, as shown in fig. 1 to 3, the cooling system 100 includes, in addition to the first cooling water pump 101, the condenser 102, the warm air core 103, the four-way valve 104, the radiator 105, the adjustable valve 106, the compressor 107, and the evaporator 108: the PTC heater 109 is connected in series between the port D of the four-way valve 104 and the first cooling water pump 101.
Considering that the amount of hot air required by the occupant is large in some cases, the heat in the refrigerant in the gaseous state in the condenser 102 as the heat source of the warm air core 103 may not be sufficient to satisfy the occupant's requirement for hot air, and an auxiliary heat source is required. In addition, there may be situations where the condenser 102 fails to provide hot air to the occupant, requiring a backup heat source. For this purpose, a PTC heater may be used as an auxiliary heat source or a backup heat source, and the PTC heater 109 may be connected in series between the port D of the four-way valve 104 and the first cooling water pump 101.
Under the condition that the condenser 102 normally works, the PTC heater 109 can work simultaneously with the condenser 102 to increase the heat provided for the warm air core 103, so that the heat provided for the warm air core 103 by the cooling system 100 is no longer limited by the heat in the gaseous refrigerant in the condenser 102, and the cooling system is suitable for the use scene with a large demand of hot air for the driver.
