Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
Compressor compresses principle analysis：
Air-conditioning system can realize that refrigeration is that refrigerant is compressed by compressor the orbiting and fixed scroll, increase refrigerant unit
The enthalpy of volume, the refrigerant after being compressed by scroll plate turn into high temperature and high pressure gas, are exchanged heat by condenser and air
After be transformed into medium temperature highly pressurised liquid, acted on by the reducing pressure by regulating flow of expansion valve, refrigerant turns into fog-like liquid, enter in evaporator
Row evaporation endothermic and in-car air are exchanged heat, and reduce in-car air themperature, realize refrigeration.By the refrigerant weight of evaporator
The new gas for becoming low-temp low-pressure circulates again into compressor.
Scroll plate can form two pairs of symmetrical closed moon teeths cavity in the course of the work, and one pair of which is suction muffler, be for a pair
Compression chamber, wherein compression cavity pressure is sub-high pressure area.
It can be seen that by the pressure-enthalpy chart for consulting the law of thermodynamics and refrigerant：
1. compressor air suction and the enthalpy difference of exhaust are bigger, the refrigeration of compressor is better.
2. the flow of compressor unit interval is bigger, the specific refrigerating effect of compressor is bigger.
The design is imported into the sub-high pressure chamber of scroll plate by increasing secondary suction, by high pressure refrigerant by pipeline connection
Second compression again, the capacity of compressor and the enthalpy of compressor are improved, to improve the refrigerating capacity of compressor and Energy Efficiency Ratio.Compression ratio
Rise cause the excessive discharge temperature of compressor, influence performance and the life-span of compressor, the design passes through lead-in portion low temperature
The refrigerant of low pressure enters in end cap low pressure chamber the temperature that heat exchange reduction compressor discharge chamber is carried out with compressor high pressure chest, to reduce
Compressor exhaust temperature, and the degree of superheat of suction end refrigerant and the degree of supercooling of delivery temperature are improved, realize compressor performance
It is substantially improved.Concrete scheme is as follows：
As shown in Figures 1 to 9, a kind of new mixed gas increasing enthalpy design pure electric automobile air conditioning compressor, including it is bottom 1, outer
Shell 2, mixed gas heat sink, scroll compression body 3 and power transmission shaft 4, the bottom 1, shell 2, mixed gas heat sink pass sequentially through
Bolt connection, the scroll compression body 3 are connected and are installed in shell 2 with power transmission shaft 4, are all provided with the bottom 1 and shell 2
Bearing assembly is equipped with, the power transmission shaft 4 is installed in bearing assembly, and the bottom 1 is provided with suction hole 5, the mixed gas cooling
Device includes top cover 6, refrigerant air inlet 7, high-pressure exhaust 8 and UNICOM's pipeline 9, the refrigerant air inlet 7, high-pressure exhaust
8 and UNICOM's pipeline 9 be arranged in top cover 6, the outside of refrigerant air inlet 7 connects with suction hole 5, the inner end of high-pressure exhaust 8
Connected respectively with the discharge chamber 12 of scroll compression body 3 and the outer end of UNICOM's pipeline 9 with outer end, the inlet end of UNICOM's pipeline 9 with
The sub-high pressure compressional zone connection of scroll compression body 3.
