[0022] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments.

[0023] Example 1: As Figure 1 As shown, a vehicle air conditioning system based on cryogenic liquid vaporization provides both cooling and heating energy. The system includes a heat exchanger assembly 10, comprising a cooling / heating heat exchanger 1. The cooling / heating medium inlet of the cooling / heating heat exchanger 1 is connected to a cooling / heating medium input pipe 11, and the cooling / heating medium outlet of the cooling / heating heat exchanger 1 is provided with a cooling / heating medium output pipe 12. Both the cooling / heating medium input pipe 11 and the cooling / heating medium output pipe 12 are connected to a carburetor 3 for vaporizing the cryogenic liquid. The carburetor 3 is also connected to an engine coolant input pipe 31 and an engine coolant output pipe 32. The cooling / heating medium in the cooling / heating heat exchanger 1 is the same medium as the engine coolant. The cooling / heating medium input pipe 11, the cooling / heating medium output pipe 12, the engine coolant input pipe 31, and the engine coolant output pipe 32 are all connected to the shell side of the carburetor 3.

[0024] The engine coolant, after being cooled and heated, enters the carburetor 3 through the engine coolant inlet pipe 31. The medium (including the mixed engine coolant and cooling / heating medium) that exchanges heat with the cryogenic liquid in the shell side of the carburetor 3 is partially output through the engine coolant outlet pipe 32, and the other part enters the cooling / heating heat exchanger 1 through the cooling / heating medium inlet pipe 11. A pump 111 is installed on the cooling / heating medium inlet pipe 11. In this embodiment, the cryogenic liquid is liquefied natural gas.

[0025] In this embodiment, the cold and heat energy supply system of a vehicle air conditioner based on cryogenic liquid vaporization also includes a cold energy replenishment mechanism 4 that can provide additional cold energy.

[0026] In this embodiment, the cooling capacity replenishment mechanism 4 includes: a cooler 41 disposed in the cooling / heating medium input pipeline 11 for cooling the cooling / heating medium in the cooling / heating medium input pipeline 11; a refrigerant circulation pipeline 42 connected to the cooler 41; and a refrigerant electric compressor 421, a refrigerant condenser 422, and a refrigerant throttling component 423 disposed on the refrigerant circulation pipeline 42. The refrigerant used to cool the cooling / heating medium in the cooling / heating medium input pipeline 11 is compressed by the refrigerant electric compressor 421, condensed by the refrigerant condenser 422, and throttled by the refrigerant throttling component 423 before entering the cooler 41 to cool the cooling / heating medium. After releasing its cooling capacity, the refrigerant is output from the cooler 41 and is again compressed by the electric compressor 421, condensed by the refrigerant condenser 422, and throttled by the refrigerant throttling component 423, thus cyclically replenishing the cooling capacity.

[0027] In this embodiment, a temperature sensor 101 is provided on the cooling / heating medium input pipeline 11 for monitoring the temperature of the cooling / heating medium entering the cooling / heating heat exchanger 1.

[0028] A check valve 121 is provided at the outlet of the cooling and heating medium output pipeline 12 to prevent the medium in the vaporizer 3 from entering the cooling and heating medium output pipeline 12.

[0029] A vehicle air conditioning system based on cryogenic liquid vaporization for supplying cold and heat energy also includes a fan 6, which is mounted on the first housing 100 where the heat exchanger assembly 10 is located.

[0030] The working principle is as follows: Figure 1 As shown, the cryogenic liquid in the vehicle-mounted cryogenic storage tank 5 enters the vaporizer 3 through the cryogenic liquid inlet pipe 51 and is vaporized. The vaporized product is output through the first vaporization outlet pipe 52 and the second vaporization outlet pipe 53. The vaporized product output from the first vaporization outlet pipe 52 is used as fuel for the engine, while the vaporized product output from the second vaporization outlet pipe 53 flows back to the vehicle-mounted cryogenic storage tank 5 for gas-phase pressurization or liquid-phase saturation. Cryogenic liquids, such as liquefied natural gas (-163℃), release a large amount of cold energy during vaporization.

[0031] The engine coolant, after being cooled and then heated, typically reaches a temperature of 90℃±5℃. This heated coolant enters the shell side of the carburetor 3 via the engine coolant inlet pipe 31. The refrigerant / heating medium in the refrigerant / heating heat exchanger 1, after heat exchange with air, also enters the shell side of the carburetor 3 via the refrigerant / heating medium outlet pipe 12. The engine coolant and the refrigerant / heating medium are the same medium; they mix in the shell side of the carburetor 3, providing heat for the vaporization of the cryogenic liquid. The heat energy of the engine coolant is fully released within the carburetor 3. The medium after sufficient heat exchange with the cryogenic liquid in the shell side of the carburetor 3—the mixed engine coolant and refrigerant—is partially output via the engine coolant outlet pipe 32 for reuse in engine cooling, and the other part enters the refrigerant / heating medium inlet pipe 11, where it is pumped into the refrigerant / heating heat exchanger 1 by the pump 111.

[0032] The temperature of the cooling or heating medium output by the carburetor 3 can be adjusted by regulating the amount of heated engine coolant entering the carburetor 3, thereby providing cold or heat energy to the vehicle air conditioner based on cryogenic liquid vaporization and realizing the temperature regulation of the vehicle air conditioner for cooling or heating.

[0033] The fan 6 blows in ambient air, causing the heat or cold energy of the cooling and heating heat exchanger 1 to exchange heat with the air quickly, thereby providing heating or cooling services for the vehicle.

[0034] In this embodiment, a cooling capacity replenishment mechanism 4 is provided. The purpose of the cooling capacity replenishment mechanism 4 is as follows: When the car engine is idle, the amount of cryogenic liquid entering the carburetor 3 decreases. To ensure the cooling needs of the vehicle's air conditioning, the cooling capacity replenishment mechanism 4 can be activated. The refrigerant used to cool the cooling / heating medium in the cooling / heating medium input pipe 11 is compressed by the refrigerant electric compressor 421, condensed by the refrigerant condenser 422, and throttled by the refrigerant throttling component 423 before entering the cooler 41 to cool the cooling / heating medium. This replenishes the cooling capacity of the cooling / heating medium in the cooling / heating medium input pipe 11. After releasing the cooling capacity, the refrigerant is output from the cooler 41 and is again compressed by the electric compressor 421, condensed by the refrigerant condenser 422, and throttled by the refrigerant throttling component 423, thus continuously circulating the cooling system. The cooling capacity replenishment mechanism 4 ensures that even when the vehicle's engine is idle or the cooling capacity of other cryogenic liquids is insufficient, there is still enough cooling capacity to maintain the vehicle's cooling requirements.

[0035] Example 2: Figure 2As shown, the difference between this embodiment and Embodiment 1 is that the heat exchanger assembly 10 further includes a heating heat exchanger 2. The heating medium in the heating heat exchanger 2 is engine coolant that has been heated after engine cooling. The fan 6 blows in ambient air, causing the cooling and heating heat exchangers 1 and 2 of the heat exchanger assembly 10 to quickly exchange heat with the air.

[0036] Compared to Embodiment 1, in this embodiment, the heat exchanger assembly 10 includes a cooling / heating heat exchanger 1 and a heating heat exchanger 2. This has the advantage of allowing the vehicle air conditioner based on cryogenic liquid vaporization to simultaneously cool and heat, generating both cold and hot air under the action of the fan 6, thus greatly improving human comfort. Furthermore, when the heating heat exchanger 2 is used for heating, the cooling / heating heat exchanger 1 can be used for cooling, meaning that it can simultaneously use cold air for defogging and defrosting while heating is in operation.

[0037] Example 3: As Figure 3 As shown, in this embodiment, compared to embodiment 1, the cooling capacity replenishment mechanism 4 adopts a refrigerant compression single refrigeration circuit mechanism. The refrigerant compression single refrigeration circuit mechanism includes: a refrigerant replenishment circuit 41, which is equipped with a replenishment electric compressor 411, a replenishment condenser 412, a replenishment throttling component 413, and a replenishment evaporator 414. The replenishment evaporator 414 uses a fan for heat dissipation.

[0038] In this embodiment, the supplementary cooling evaporator 414 and the heat exchanger assembly 10 are disposed in the same housing, that is, both are in the first housing 100. In this way, the supplementary cooling evaporator 414 and the heat exchanger assembly 10 can share a fan 6, and the ambient air blown in by the fan 6 can quickly exchange heat.

[0039] Compared to Embodiment 1, in this embodiment, the cold energy replenishment mechanism 4 adopts a refrigerant compression single refrigeration circuit mechanism. In this way, when the vehicle engine is idle or the amount of cryogenic liquid entering the carburetor 3 is reduced, in order to ensure the cooling needs of the vehicle air conditioning, the cold energy replenishment mechanism 4 can be activated to supplement the cold energy using the refrigerant compression single refrigeration circuit mechanism to meet the cooling requirements.

[0040] Furthermore, due to the refrigerant compression single refrigeration circuit mechanism, the refrigerant compression single refrigeration circuit mechanism and the refrigeration and heating heat exchanger 1 can work independently. When it is necessary to generate cold air and hot air at the same time, the refrigerant compression single refrigeration circuit mechanism is used for refrigeration, and the refrigeration and heating heat exchanger 1 is used for heating. This allows the vehicle air conditioner based on cryogenic liquid vaporization to generate cold air and hot air at the same time, so as to improve human comfort, or to use cold air for defogging and defrosting at the same time when heating.

[0041] Example 4: Figure 4 As shown, in this embodiment, compared to embodiment 3, the cooling capacity replenishment mechanism 4 also adopts a refrigerant compression single refrigeration loop mechanism. The difference lies in that the supplementary cooling evaporator 414 and the heat exchanger assembly are respectively housed in different casings, each casing having a fan. The casing containing the heat exchanger assembly 10 is the first casing 100, and the first fan 6 is mounted on the first casing 100, exchanging heat between the heat exchanger assembly 10 and the air blown in by the first fan 6. The casing containing the supplementary cooling evaporator 414 is the second casing 200, and the second fan 8 is mounted on the second casing 200, exchanging heat between the supplementary cooling evaporator 414 and the air blown in by the second fan 8.

[0042] Example 5: See Figure 1 , Figure 2 , Figure 3 , Figure 4 The difference between this embodiment and embodiments 1, 2, 3, or 4 is that a cold storage tank 7 is installed on the cooling / heating medium output pipeline 12. The cold storage tank 7 is connected to a cold storage tank input pipe 71 and a cold storage tank output pipe 72, both of which are connected to the cooling / heating medium output pipeline 12. To simplify the piping, the cold storage tank input pipe 71 and the cooling / heating medium output pipeline 12 are connected via a three-way valve 73. A cold storage tank temperature sensor 701 is installed on the cold storage tank 7 to monitor the temperature inside the cold storage tank 7.

[0043] The purpose of the cold storage box 7 is to store cold energy.

[0044] When the car is first started, the cooling / heating medium in the cold storage tank 7 can be used for rapid cooling. The specific working process is as follows: The three-way valve 73 is controlled to connect the cooling / heating medium output pipe 12 to the cold storage tank input pipe 71. In this way, the cooling / heating medium in the cold storage tank 7 will sequentially enter the vaporizer 3 through the cold storage tank output pipe 72 and the cooling / heating medium output pipe 12. The medium in the vaporizer 3 will then enter the cooling / heating heat exchanger 1 through the cooling / heating medium input pipe 11, pumped by the pump 111, thereby achieving rapid cooling. The cooling / heating medium that has released its cooling capacity in the cooling / heating heat exchanger 1 will flow back to the cold storage tank 7 through the cold storage tank input pipe 71, thus circulating and achieving rapid cooling inside the vehicle.

[0045] When the vehicle air conditioner is not needed, the cooling and heating medium in the cooling and heating medium output pipe 12 enters the cold storage box 7 through the cold storage box input pipe 71 for storage. In this way, the cooling capacity can be stored in the cold storage box 7, thereby reducing the waste of cooling capacity.

[0046] Alternatively, when the temperature signal monitored by the cold storage box temperature sensor 701 indicates that the temperature in the cold storage box 7 is higher than the set value, the three-way valve 73 is controlled to connect the cooling / heating medium output pipe 12 with the cold storage box input pipe 71. The cooling / heating medium in the cooling / heating medium output pipe 12 enters the cold storage box 7 through the cold storage box input pipe 71. The cooling / heating medium in the cold storage box 7 then enters the vaporizer 3 through the cold storage box output pipe 72 and the cooling / heating medium output pipe 12, thus circulating until the temperature of the cooling / heating medium in the cold storage box 7 reaches the set value.

[0047] As can be seen from the above embodiments, the vehicle air conditioning system based on cryogenic liquid vaporization described in this application for supplying cold and hot energy has the following advantages: 1. It has a simple structure and makes full use of the cold energy during cryogenic liquid vaporization and the heat energy of the engine coolant after the engine is cooled, thereby providing cooling and / or heating for the vehicle and effectively reducing the vehicle's energy consumption. 2. The cooling capacity replenishment mechanism 4 effectively ensures that even when the vehicle's engine is idle or when the amount of cryogenic liquid entering the carburetor 3 is reduced, there is still sufficient cooling capacity to maintain the vehicle's cooling requirements. Third, when the cold capacity replenishment mechanism 4 provides additional cold capacity to the cooling and heating medium in the cooling and heating medium input pipe 11, the heat exchanger assembly 10 is also equipped with a heating heat exchanger 2. In this state, the vehicle air conditioner based on cryogenic liquid vaporization can generate both cold and hot air to improve human comfort. It can also use cold air for defogging and defrosting while heating. When the cold capacity replenishment mechanism 4 adopts a refrigerant compression single refrigeration circuit mechanism to directly exchange heat with the air to replenish cold capacity, the vehicle air conditioner based on cryogenic liquid vaporization can also generate both cold and hot air to improve human comfort. It can also use cold air for defogging and defrosting while heating.
