Specific implementation mode
In the following detailed description, a large amount of specific details are proposed, in order to provide the thorough understanding to the utility model.But
It is, it will be understood by those within the art that the utility model can be implemented without these specific details.In other situations
Under, it is not described in well-known method, process, component and circuit, in order to avoid influence the understanding to the utility model.
In conjunction with shown in Figure 1, embodiment according to the present utility model, air-conditioning includes sequentially connected compressor 1, outdoor
The gas outlet end of heat exchanger 2, flash vessel 3 and indoor heat exchanger 4, flash vessel 3 is connected to compressor 1 by cooling line 5
Air entry is provided with the cooling device to cool down to air conditioning circuit board on cooling line 5.
When air-conditioning work, gas-liquid separation can be carried out to refrigerant by flash vessel 3 so that liquid refrigerant continues to participate in
Into subsequent heat transfer process, gas refrigerant can cool down air conditioning circuit board through cooling line 5, flow back to later
The suction end of compressor 1, so as to reduce on it is subsequent refrigeration or heating effect influence on the basis of, to airconditioning control
Plate carries out effectively drop heat so that the running frequency of air conditioner can be coordinated with heat exchange amount, ensure refrigeration or the heating of air conditioner
Amount improves comfort level when user uses.Meanwhile the gas refrigerant through cooling line 5 can also with from indoor heat exchanger or
The mixing in gas-liquid separator 6 of the gas refrigerant of person's outdoor heat exchanger outflow, enters the gas refrigeration of compressor 1 later
Agent temperature improves the work efficiency of compressor 1, the compression ratio of air-conditioning is improved, to reach the technique effect of Gas-supplying enthalpy-increasing.
First throttling device 7 and/or outdoor heat exchanger 2 and flash vessel 3 are provided between indoor heat exchanger 4 and flash vessel 3
Between be provided with second throttling device 8.In the present embodiment, between indoor heat exchanger 4 and flash vessel 3 and outdoor heat exchanger 2
It is both provided with throttling set between flash vessel 3, thus, regardless of air conditioner is to be in heating state or refrigerating state,
An expenditure and pressure can be carried out to refrigerant before refrigerant enters flash vessel so that can be generated in flash vessel 3
Enough gas refrigerants are participated in gas-liquid separator 6 in the temperature-fall period for the refrigerant for being back to compressor, ensureing compression
The compression efficiency of machine 1.
In conjunction with shown in Figure 1, in the air-conditioning of the first embodiment of the utility model, the gas outlet end of flash vessel 3
It is provided with third throttling set 9 between cooling device, can further be carried out to entering the refrigerant in cooling line 5
Decompression cooling, reduces the temperature of gas refrigerant, improves the heat exchange efficiency of gas refrigerant and the refrigerant of reflux, improves compressor
1 compression performance.
In some embodiments of this case, gas-liquid separator 6 is provided with the first liquid level inductor, for monitoring gas-liquid
The liquid level of liquid refrigerants in separator, to avoid the liquid refrigerants in gas-liquid separator it is excessive and cause refrigerant to overflow,
The problem of blocking refrigerant pipeline.
In some embodiments of this case, flash vessel 3 is provided with the second liquid level inductor, for monitoring in flash vessel
Liquid refrigerants liquid level, it is excessive and cause refrigerant to overflow, block refrigerant to avoid the liquid refrigerants in gas-liquid separator
The problem of pipeline.
The course of work of air-conditioning when being in refrigerating state to air conditioner below is illustrated：
Refrigerant is after the discharge of the exhaust end of compressor 1, after the condensing heat-exchange of outdoor heat exchanger 2, is filled through the second throttling
Set 8 expenditure and pressures, refrigerant becomes vehicle repair major state, and two phase refrigerants enter in flash vessel 3, and gas refrigerant is from flash vessel
3 gas outlet end enters in cooling line 5, flows to the import of gas-liquid separator 6.Liquid refrigerant in flash vessel 3
From the liquid outlet of flash vessel 3 after 7 expenditure and pressure of first throttling device, get in heat exchanger 4 and exchange heat, after pass through
Four-way valve flows back into the suction end of compressor 1.In the process, the flow control valve 11 on bypass line 10 can be adjusted, with
Just the amount for flowing through the gas refrigerant in cooling device is adjusted.Compressor 1 can be effectively reduced in this manner
Suction end temperature improves the work efficiency of compressor 1.
For the especially new environmental protection R32 refrigerants of the refrigerant in air-conditioning, refrigerant characteristic causes delivery temperature cold compared with R410A
Matchmaker is 10-15 DEG C high, and delivery temperature can not be reduced effectively, can lead to the compressor meeting frequent start-stop of high temperature protection, the lost of life.Pass through
Control to third throttling set 9 can allow the air-breathing of compressor 1 to carry a certain amount of liquid coolant, to effectively
The temperature for reducing exhaust, by test, refrigerant mass dryness fraction cooling-down effect between 0.65-0.8 is apparent at compressor air suction.
On the contrary, in heating operations when the course of work and refrigeration of air-conditioning when air conditioner heat-production, gas refrigerant is from cooling
Pipeline 5 flows back to the suction end of compressor 1, can not only increase cold medium flux, and can play the effect of Gas-supplying enthalpy-increasing.Herein
Under kind state, into the refrigerant of outdoor heat exchanger 2 closer to liquid phase, crushing reduces when than two-phase state, and pressure of inspiration(Pi) rises, and makes
It obtains refrigerant circulation to increase, and pressure of inspiration(Pi) rising advantage is bigger under the lower heating situation of outdoor temperature, the density of superheated steam
It dramatically increases, refrigerant circulation increase ratio is bigger, and heating capacity is promoted higher；The high refrigerant steam of mass dryness fraction sprays into air entry, inhales
Gas specific enthalpy increases, and can effectively promote heating capacity.
The explanation of above example is only intended to the method and its core concept that help understands the utility model；Meanwhile it is right
It is had in specific embodiments and applications according to the thought of the utility model in those of ordinary skill in the art
Change place, in conclusion the content of the present specification should not be construed as a limitation of the present invention.
