Abstract
The utility model relates to the technical field of an air-conditioning heat pump, and provides an air- conditioning outdoor uint system. The air- conditioning outdoor uint system comprises a gas-liquid separation device, a compressor, a four-way valve, an outdoor heat exchanger and a throttling device. The gas-liquid separation device comprises at least two gas-liquid separators connected with each other in parallel . The air-conditioning outdoor uint system utilizes at least two small-volume gas-liquid separators connected with each other in parallel to carry out gas-liquid separation. Compared with a prior large-volume gas-liquid separator, the air- conditioning outdoor uint system has the advantages that a tank body of a small-volume gas-liquid separator is small, the return-air pressure difference needed to be overcome is small, the resistance loss of the return-air is reduced, the flow velocity of a refrigerant is quickened, the oil return speed is enhanced in the meantime, and the reliability of operation of the whole system is improved.
Description
Technical field
The utility model relates to technical field of air-conditioning heat pumps, more particularly, relates to a kind of air conditioner outdoor unit system that can reduce system's return-air pressure drop, reduce the refrigerant pressure loss.
Background technology
In the present multi-online air-conditioning system, the effect of gas-liquid separator in system is to separate and preserve liquid in the muffler to prevent the compressor liquid hammer.Gas-liquid separator can temporarily store unnecessary refrigerant, prevents that unnecessary cold medium compressor crankcase from causing dilution to oil.Gas-liquid separator is in separation process, and refrigeration oil is separated and accumulates in the bottom, and has a spill port in the bottom of gas-liquid separator outlet, and the assurance refrigeration oil can be got back to compressor, thereby avoids the compressor oil starvation.But when system volume is larger, and system installs pipe arrangement when longer, and the coolant quantity that contains in the system can increase, and for avoiding the normal lubricated of compressor liquid hammer and arbor, system need to select the gas-liquid separator of large volume, to guarantee the normal operation of system.But simultaneously, the gas-liquid separator of large volume, the pressure reduction that compressor return air need to overcome is larger, the return-air resistance increases, the oil return effect of compressor also can reduce, and system's operation exists unstable hidden danger, and large volume gas-liquid separator manufacture difficulty is large, manufacturing cost is high.Although, in some system knockout drum has been done improvement at present, be respectively arranged with conveying pipe of refrigerant road and lower conveying pipe of refrigerant road at the top and bottom of tank body, utilized so to greatest extent the liquid storage function of tank body, also increase cold medium flux simultaneously.But this mode also exists compressor to return the possibility of liquid simultaneously so that the compressor return air resistance increases greatly, and there is unstable hidden danger in system's operation.
The utility model content
Technical problem to be solved in the utility model is to overcome the defective of prior art, provides simple in structure, can reduce the air conditioner outdoor unit system of system's return-air pressure drop, the minimizing refrigerant pressure loss.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of air conditioner outdoor unit system is provided, comprise gas-liquid separation device, compressor, cross valve, outdoor heat exchanger and throttling arrangement, described gas-liquid separation device comprises at least two gas-liquid separators parallel with one another.
Particularly, the air inlet of each described gas-liquid separator is connected with described cross valve by after the three-way pipe parallel connection; The gas outlet of each described gas-liquid separator is connected with described compressor by after the three-way pipe parallel connection.
Further, each described gas-liquid separator volume is identical.
Perhaps, each described gas-liquid separator volume is not identical.
In the utility model, adopt the mode of the gas-liquid separator parallel connection of at least two little volumes to carry out gas-liquid separation, the existing gas-liquid separator that adopts a large volume, the tank body of the gas-liquid separator of little volume is little, the pressure differential that return-air need to overcome is little, and the return-air drag losses reduces, and refrigerant flow rate is accelerated, oil return speed also improves greatly simultaneously, has improved the whole system reliability of operation.
Description of drawings
Fig. 1 is the structural representation of air conditioner outdoor unit system one preferred embodiment that provides of the utility model.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
With reference to Fig. 1, the utility model provides a kind of Novel multi-connected air conditioner system, comprise gas-liquid separation device 100, compressor 200, cross valve 300, outdoor heat exchanger 400 and throttling arrangement 500, wherein, gas-liquid separation device 100 comprises at least two gas-liquid separators parallel with one another 110.
Particularly, in the present embodiment, gas-liquid separator 110 is two, the structure of these two gas-liquid separators 110 is identical with existing large volume structure of gas liquid separator, do not give unnecessary details herein, the volume that is not both gas-liquid separator 110 in the present embodiment is less, and the volume of two gas-liquid separators 110 is identical, and the volume sum of two gas-liquid separators 110 is the volume of the required gas-liquid separator of system.When being installed in parallel, the air inlet of each gas-liquid separator 110 is connected with cross valve 300 by a three-way pipe 120 parallel connections are rear; The gas outlet of each gas-liquid separator 110 is connected with compressor 200 by a three-way pipe 120 parallel connections are rear.And so separately be arranged in parallel, the volume of single gas-liquid separator 110 tank bodies is little, and like this, the pressure differential that need to overcome during return-air is little, and the return-air drag losses is low, and refrigerant flow rate is fast, and oil return speed also improves greatly simultaneously, has improved the whole system reliability of operation.Certainly, gas-liquid separator 110 also can be not limited to two in the present embodiment for a plurality of, and the volume of gas-liquid separator 110 can be not identical yet.
Below only be preferred embodiment of the present utility model, not in order to limiting the utility model, all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
