The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The air conditioning system provided by the embodiment of the invention comprises a compressor 11, a condenser 12 and an evaporator 13; the compressor 11 includes a compression chamber 17 for compressing a refrigerant, and is improved in that,
the compressor 11 further comprises a flash chamber 18 capable of performing flash of the liquid refrigerant, and a communication passage 19 communicating between a gas outlet 181 of the flash chamber 18 and an enthalpy-increasing air-supplementing port 171 of the compression chamber 17;
the inlet 182 of the flash chamber 18 is connected to the outlet 121 of the condenser 12, and the liquid outlet 183 of the flash chamber 18 is connected to the liquid inlet 131 of the evaporator 13, and the structure thereof can be shown with reference to fig. 2 and 3.
Working principle: the low-pressure refrigerant gas evaporated from the evaporator 13 is continuously sucked into the compressor 11 for compression, the refrigerant gas with low pressure Ps is compressed into high-pressure Pd refrigerant gas which is discharged from the compressor 11 and enters the condenser 12, the high-temperature high-pressure refrigerant gas is isobarically cooled in the condenser 12 and then enters the flash cavity 18 part of the compressor 11, the liquid refrigerant is subjected to flash evaporation in the flash cavity 18, the flash refrigerant gas directly enters the compression cavity 17 through the connecting passage 19, the effect of cooling and enthalpy increasing of the compression cavity 17 is realized, the refrigerant liquid which is not subjected to flash evaporation heat exchange enters the evaporator 13 for evaporation heat exchange, and the low-pressure refrigerant gas subjected to evaporation heat exchange is continuously sucked into the compression cavity 17 of the compressor 11 for compression, so that the circulation of the refrigerant in an air conditioning system is realized, and the mechanical energy is continuously utilized for working and converted into heat energy.
According to the technical scheme, the air conditioning system provided by the embodiment of the invention has the advantages that the flash device and the compressor 11 are integrally designed, so that the structure and the space of the flash device are additionally increased in the system, and the air conditioning system is simplified; meanwhile, the gas after flash evaporation can quickly enter the compression cavity 17, so that the pressure loss and heat transfer and temperature rise of the intermediate pipeline are reduced, the air supplementing and enthalpy increasing efficiency is improved, and the low-temperature heating performance of the compressor is further improved; in addition, the flash structure arranged on the compressor 11 is fixedly connected with the compressor 11 on the automobile, so that the automobile has better vibration resistance performance than the traditional air conditioning system with the flash structure, and the reliability of the whole vehicle-mounted enthalpy-increasing system is improved. The design is particularly suitable for an on-board enthalpy-increasing air conditioning system.
Preferably, the flash chamber 18 is adjacent to the compression chamber 17, with the two chambers sharing a single sidewall. Therefore, the structure of the air conditioning system is further simplified, the distance between the two cavities is shortened, the connecting passage 19 is as short as possible, the pressure loss and the heat transfer temperature rise of the middle pipeline are reduced, the air supplementing enthalpy increasing efficiency is improved, and the low-temperature heating performance of the compressor is further improved.
In the embodiment provided in this embodiment, the communication channel 19 is disposed on the common side wall.
In order to further optimize the technical scheme, the through holes are formed in the common side wall and serve as the communication channels 19 to directly communicate the gas outlet 181 of the flash chamber 18 with the enthalpy-increasing and gas-supplementing interface 171 of the compression chamber 17, so that the intermediate cooling gas flash-emitted by the flash chamber 18 can directly enter the compression chamber 17, and the enthalpy-increasing cooling effect is better.
Preferably, the outer wall surface of the body of the compressor 11 is formed as a part of the flash chamber 18. The connection of each pipeline of the flash cavity 18 is facilitated while the simplified structure of the outer wall surface of the machine body is fully utilized. As shown in fig. 3, the compression chamber 17 is centrally disposed, the flash chamber 18 is located at one side thereof, and the driving part is located at the other side, thus constituting the main body of the compressor 11, and having a compact structure.
In order to further optimize the above technical solution, the compressor 11 is an aluminum alloy body. The aluminum alloy open type structure has more machinable types compared with the traditional steel plate cylinder totally-enclosed structure by fully utilizing the machinability characteristic of the aluminum alloy machine body of the compressor. Because of the aluminum alloy body structure of the compressor, the external flash generator structure is designed on the whole compressor in an integrated way very conveniently, and the advantage configuration of the integrated structure can be fully exerted.
In the specific embodiment provided by the scheme, the compressor 11 is an electric compressor and comprises a driving motor 16 part for driving the pump body to compress, a compression cavity 17 is adopted for centering, and the flash cavity 18 and the driving motor 16 are respectively positioned on two sides of the compression cavity, so that the structure is compact.
The invention provides an enthalpy-increasing air conditioning system for an electric vehicle, which mainly comprises four parts, namely a compressor 11, a condenser 12, an evaporator 13 and a system pipeline 14. The compressor 11 integrates the suction, compression, exhaust and middle flash, so that the whole enthalpy-increasing system is compact in structure and high in reliability. The integrated compressor 11 of the present invention includes: the driving motor 16 part for driving the pump body to compress, the compression cavity 17 part for compressing the refrigerant, the flash cavity 18 part for enabling the flash of the liquid refrigerant and the communication channel 19 between the flash cavity and the compression cavity.
Unlike the prior art enthalpy-increasing air conditioning system shown in fig. 1, the present invention needs to additionally arrange a flash device 05 structure between the compressor 01 and the condenser 02, and the refrigerant gas flash-emitted by the flash device 05 needs to enter the compression cavity of the compressor 01 after passing through the connecting pipelines a and b to realize enthalpy-increasing air supply. Compared with the air conditioning system in the prior art, the air conditioning system of the invention has the following characteristics;
1. lightweight air conditioning system:
the vehicle-mounted air conditioning system is different from a household or commercial air conditioning system, the internal installation space is limited, the system is as light as possible, and particularly, the requirements of an electric automobile are strict, and a battery is required to provide power for a driving motor and also required to provide power for the vehicle-mounted air conditioning system. Therefore, the electric vehicle requires a lighter vehicle body configuration for delayed cruising ability, and in order to reduce the weight, the compressor for the electric vehicle generally adopts an aluminum alloy open type structure, which has more machinability than a conventional steel plate cylinder fully-closed structure. Because of the aluminum alloy body structure of the compressor, the external flash generator structure is designed on the whole compressor in an integrated way very conveniently, and the advantage configuration of the integrated structure can be fully exerted. The vehicle-mounted air conditioning system shown in fig. 2 is more compact in system configuration due to the lack of the flash chamber structure arrangement compared with the existing system, and the integrated compressor body is more advantageous in space than the additional addition of the flash chamber device because the peripheral space of the compressor body can be fully utilized when the flash chamber body is designed, so that the integrated design is more compact. The traditional flash device is provided with a special flash tank in the system, and then is connected with a compressor, a condenser and an evaporator through pipelines, while the integrated flash device cavity is arranged on the body of the compressor, namely the outer wall surface of the body of the compressor is used as a part of the structure of the flash cavity.
2. The air supplementing enthalpy increasing passage is short, the air supplementing effect is more stable, and the indoor temperature with more comfortable temperature can be provided:
when the enthalpy-increasing air conditioning system is arranged, the length of the pipeline between the ends a and b is difficult to be taken as a primary consideration, and the external environment temperature of the pipeline is influenced by the running speed of an automobile. Therefore, the refrigerant gas flashed from the flash evaporator has poor enthalpy increasing effect compared with the refrigerant gas flashed from the flash evaporator cavity and directly entering the compression cavity because of the change of gas state attribute caused by pressure loss and heat transfer, and the actual running condition of the compressor is unstable so as to cause indoor temperature fluctuation to influence indoor comfort, and meanwhile, the reliability of the compressor is also influenced due to the fluctuation of the working condition of the compressor.
3. The integrated structural design ensures that the enthalpy increasing system has good vibration resistance:
compared with household or commercial air conditioning systems, the vehicle-mounted air conditioning system vibrates severely, and has higher vibration resistance requirement on the vehicle-mounted air conditioning system. The structure design of the integrated flash evaporator structure and the compressor body adopted by the invention is that the flash evaporator cavity 18 is integrally fixed on the vehicle body with the compressor as a part of the structure of the compressor as shown in fig. 3, and has the same vibration characteristic as the compressor, while the structure of the flash evaporator 05 and the compressor are respectively fixed on the vehicle body as shown in the prior art scheme shown in fig. 1, and are influenced by the structure of the flash evaporator and the vibration characteristic of the flash evaporator, so that the enthalpy increasing pipeline connected between the flash evaporator and the compressor vibrates severely, thereby influencing the reliability of the whole system. The enthalpy increasing pipeline connected between the flash evaporator and the compression cavity in the embodiment of the invention is directly arranged in the compressor, and no pipeline vibration exists at the enthalpy increasing pipeline. Therefore, the vibration resistance of the whole enthalpy increasing system is better.
As shown in the structural schematic diagram of an integrated compressor in the embodiment of the invention shown in FIG. 3, a flash cavity is arranged on a compressor of an aluminum alloy body and is directly communicated with a compression cavity, and the flash cavity enters the compression cavity to cool the compression cavity once flash is performed, so that the enthalpy-increasing cooling effect is better.
The embodiment of the invention also provides an automobile, which comprises an air conditioning system, and the core improvement point is that the air conditioning system is the air conditioning system. In particular to a new energy automobile, especially an electric automobile.
The design is more suitable for the electric vehicle enthalpy-increasing air conditioning system, the integrated design of the cooling flash device in the vehicle-mounted electric compressor is simplified, the reliability of the system is improved, and the ultra-low temperature rapid heating requirement of the air conditioning system for the electric vehicle is met.
In summary, the embodiment of the invention provides an air conditioning system, which includes an electric compressor, an evaporator, a condenser, a flash evaporator and various pipelines connected with the whole system, wherein the flash evaporator structure and the electric compressor are integrally designed, and the actual main components only include the compressor, the evaporator, the condenser and the various pipelines connected with the whole system. The electric compressor forming the system not only comprises a driving motor and a compression cavity, but also comprises a flash cavity with a flash function. The integral compressor structure makes the whole enthalpy increasing system simpler, reduces and saves the space for additionally arranging the flash generator structure, and is more suitable for the vehicle-mounted air conditioning system with limited space. The embodiment of the invention also provides an automobile, in particular an electric automobile, using the air conditioning system.
