[background technology]
Compressor is the nucleus equipment in four big parts of air conditioner industry refrigeration system, and under certain condensation temperature, the capacity of compressor and delivery temperature largely limit the performance of whole air conditioning system.
When condensation temperature is certain, when common compressor is run under low evaporating temperature, there will be inspiratory volume to increase, refrigerant circulation reduces, pressure ratio increases, and volumetric efficiency reduces, and compressor displacement declines, heating performance and Energy Efficiency Ratio decline, and the words of excessive discharge temperature also even can make lubricating oil carbonization. When ambient temperature is too high, condensation temperature and pressure can increase accordingly, cause that compressor delivery pressure is too high and high voltage protective occurs.
Mounted air conditioner system operational effect under low temperature or hot environment is also unsatisfactory, and when outdoor temperature is lower than 0 DEG C, the degree of superheat of vaporizer is low, and heating efficiency is low, and system energy consumption is high. When ambient temperature is too high, pressure at expulsion raises, and when reaching high voltage protective point, air-conditioning will be shut down.

[accompanying drawing explanation]
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
Fig. 1 is the schematic diagram of this utility model embodiment mounted air conditioner system.
[detailed description of the invention]
The structure of this utility model embodiment mounted air conditioner system is as it is shown in figure 1, include air supply compressor 1, four-way change-over valve 2, vaporizer 8, condenser 3, gas-liquid separator 9, flash evaporation 5, unidirectional stop valve 6, expansion valve 4 and expansion valve 7.
The outlet of air supply compressor 1 connects the entrance of condenser 3 through four-way change-over valve 2, and the outlet of condenser 3 connects expansion valve 4.
The outlet of expansion valve 4 connects the entrance of flash evaporation 5, and the gaseous refrigerant outlet of flash evaporation 5 connects the second vapor injection mouth of air supply compressor 1 through unidirectional stop valve 6, and the expanded valve 7 of liquid refrigerant outlet of flash evaporation 5 connects the entrance of vaporizer 8.
The outlet of vaporizer 8 connects the entrance of gas-liquid separator 9 through four-way change-over valve 2, and the outlet of gas-liquid separator 9 connects the entrance of air supply compressor 1, and gas-liquid separator 9 is used for preventing liquid refrigerant from entering compressor 1.
Wherein, the first interface D of four-way change-over valve 2 connects the outlet of compressor 1, second interface C of four-way change-over valve 2 connects the entrance of condenser 3, and the 3rd interface E of four-way change-over valve 2 connects the outlet of vaporizer 8, and the 4th interface S of four-way change-over valve 2 connects the entrance of gas-liquid separator 9.
In cooling mode, the first interface D and the second interface C of four-way change-over valve 2 connects on-board air conditioner, the 3rd interface E and the four interface S connection; In a heating mode, first interface D and the three interface E connection of four-way change-over valve 2, the second interface C and the four interface S connection.
The coolant of this utility model above example enters flash evaporation 5 after flowing out expansion valve 4, is out divided into two-way afterwards from flash evaporation 5, and a road is gaseous refrigerant, and the intermediate cavity being accessed air supply compressor 1 by unidirectional stop valve 6 participates in circulation.
