The gas pressure entered in compressor is obtained to keep stablizing.
The utility model also provides a kind of air conditioner comprising preceding any one of them air-conditioning increasing enthalpy component.This practicality is new
Type can use flash evaporation and gas-liquid separator by the way that the increasing enthalpy component and liquid separation component setting to be an integral structure
Using integral structure, the space of installation can be effectively saved, if flash evaporation and gas-liquid separator are used two component lists
Solely installation needs the installation gap for considering all parts and fixed form and the fixed position of fixing device, using one
After formula structure, it is effectively reduced the puzzlement of mounting means and position, reduces the difficulty of installation, while more being stepped up in structure
It gathers, allows more spaces to be used for arranging other parts of air-conditioning system, also walk pipe to air-conditioning system and leave more abundant sky
Between.
It is flash evaporation that flash evaporation and gas-liquid separator, which are used integral structure, inside, and outside is gas-liquid separator, in work(
The effect of flash evaporation and gas-liquid separator can be met on energy simultaneously, while can effectively reduce the installation dimension of the two, effectively
It saves the installation space of air-conditioning system parts and reduces the difficulty of installation process.
Flash evaporation using integral structure and is sheathed on inside gas-liquid separator by flash evaporation and gas-liquid separator, is subtracted
Lack contact of the flash evaporation with outside ambient air, is effectively reduced the part of the heat transfer losses occurred with outside air
Heat has certain facilitation to the energy-saving effect of air-conditioning system operation.
Flash gas outlet pipe 12 (or blowdown pipe), shwoot inlet pipe 11 (or level-one throttling after enter flash evaporation pipe),
Shwoot liquid outlet pipe 13 (or connection enters the pipe of two-step throttle), internal heat insulating member 15, inner canister wall surface 14, end cap 3 form
One flash evaporation.Gas-liquid mixed refrigerant after level-one throttles enters flash evaporation pipe 4 after throttling by level-one enters shwoot
Device, due to the effect of gravity, gas coolant is by the gas supplementing opening of blowdown pipe connect compressor, due to depositing for internal heat insulating member 15
With the gas of outside gas-liquid separator heat exchange will not occur for gas in flash evaporation.Internal heat insulating member 15 is one close
The space closed, since the thermal coefficient of gas is very low, to which internal heat insulating member 15 plays internal flash evaporation and external gas-liquid
The heat-insulated effect of separator.Liquid coolant can be deposited on flash evaporation bottom, since flash evaporation lower half portion does not have internal insulation part
To the liquid coolant of flash evaporation lower part with the gas-liquid two-phase refrigerant in gas-liquid separator heat exchange will occur for part 15.Occur
After heat exchange, the liquid coolant of flash evaporation lower part will produce certain degree of supercooling, will produce more when it, which enters, throttles next time
Low mass dryness fraction has certain enthalpy-increasing effect, has been effectively promoted the ability and efficiency of air-conditioning system.
Liquid separation outlet pipe 22 (or compressor suction duct), liquid separation inlet pipe 21 (or evaporator outlet pipe), first shell 14
(or inner canister wall surface), second shell 23 (or outer tank skin), oil return hole 221, end cap 3, balancing orifice 222 constitute a gas-liquid
Separator.(discharge state of different operating mode evaporators can for the refrigerant of the gas coolant or gas-liquid two-phase that are come out from evaporator
Can be different), due to having carried out certain heat exchange with internal flash evaporation, possibility of the compressor air suction with liquid is made to drop significantly
It is low.
Internal heat insulating member 15 plays an important role in integral type flash evaporation and gas-liquid separator, if the position does not have
There is heat insulating member 15, fill temperature may be caused to spend low, gas specific volume increases, and the high-pressure cylinder volume of compressor cannot be effective
Utilization.The best implementing measure of heat insulating member 15 is inner vacuum, can achieve the effect that near adiabatic, and specific real
Possible during applying the process is more complicated, and 15 inside of heat insulating member is a space being fully sealed, and can be met in engineering
The effect used.The gas coolant that current air-conditioning system uses can also be poured in space inside it, even if there are some leakages,
It will not influence air-conditioning system.
Since flash evaporation is in the inside of tank body outwardly environment suction would not occur for integral type flash evaporation and gas-liquid separator
The situation of heat, according to individual flash evaporation.Even if external Insulation can inevitably absorb heat if being made good again to boundary's environment,
To influence the stability of flash evaporation, using integral type flash evaporation and gas-liquid separator since flash evaporation will not be with external environment sky
Gas is in direct contact, it is then not possible to the above problem occur.
The position of internal heat insulating member 15 is possibly disposed in inside inner canister, it is also possible to is arranged in outside inner canister, and heat-insulated
The specific length at position is also likely to be present certain difference, recommends at the 1/2 of 7 length of interior tube body.
Compressor suction duct, connection evaporator outlet pipe, blowdown pipe, level-one throttling after enter flash evaporation pipe, connect into
Enter the pipe of two-step throttle, altogether 5 inlet pipes, is the length, thick of the opposite relative position for depicting pipe and pipe in explanation
It carefully, may be when it is implemented, length, thickness and the material of pipe may have some differences.The end portion treatment mode of pipe also has
May be different, the end of pipe has certain notch or other shapes.
There may be filter screens for the inside of compressor suction duct prevents impurity for filtering the impurity inside air-conditioning system
Into inside compressor, the damage of compressor may be caused.
Integral type flash evaporation and gas-liquid separator inner canister wall surface, outer tank skin appearance there may be certain difference in appearance,
Such as：Internal, outside is the not cylinder of chamfering, cone or other shapes with certain angle.
The utility model is vertical integral type flash evaporation and gas-liquid separator, can may also there is horizontal integral type shwoot
Device and gas-liquid separator, compressor suction duct, connection evaporator outlet pipe, blowdown pipe, level-one throttling after enter flash evaporation pipe,
Into the arrangement of pipe of two-step throttle, there may be certain differences for connection.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.The above is only the preferred embodiment of the utility model, it is noted that for the art
