The specific embodiment
The present invention will be described in detail to reach embodiment with reference to the accompanying drawings.
Fig. 1 is the air-conditioner outdoor unit broken section structural representation of the present invention the 1st embodiment; Fig. 2 is the Facad structure schematic diagram of the present invention the 1st embodiment; Fig. 3 is the vertical profile structural representation of the present invention the 1st embodiment.
As shown in Figure 1, the air-conditioner outdoor unit of the present invention the 1st embodiment comprise several compressors 50 of being used for compression refrigerant, allow outdoor heat converter 60 that refrigerant and the outdoor air of compressor 50 compressions carry out heat exchange, supply the gas-liquid separator 70 of gaseous coolants to several compressors 50.
As Fig. 2, shown in Figure 3, gas-liquid separator 70 comprises the housing 72 of storing liquid or gaseous coolant; Refrigerant inflow pipe 74 to housing 72 inner water conservancy diversion liquid state or gaseous coolant; Only the gaseous coolant of housing 72 inside is supplied to several refrigerant discharge pipes 76 of several compressors 50; Be arranged on refrigerant inflow pipe 74 terminal 74a and prevent that the liquid refrigerants in gaseous state and the liquid refrigerants is splashed to the mesh screen portion 80 on next door.
Here, the lower side space of housing 72 inside is storing liquid refrigerants, and the upside space of housing 72 is storing gaseous coolant.
One end (not shown) of refrigerant inflow pipe 74 is connected on the evaporimeter (not shown), and terminal 74a runs through the upper center of above-mentioned housing 72, is connected the inboard of housing 72.
One end (not shown) of above-mentioned several refrigerant discharge pipes 76 is connected on the compressor 50, and terminal 76a runs through housing 72, is connected the gaseous coolant storage area of housing 72 inboards.
The terminal 76a of several refrigerant discharge pipes 76 is higher than the terminal 74a of refrigerant inflow pipe 74, prevents to flow directly into refrigerant discharge pipe 76 by the liquid refrigerants that refrigerant inflow pipe 74 flows into.
Several refrigerant discharge pipes 76 are fixed on the inwall of housing 72, in the present embodiment refrigerant discharge pipe 76 by spot-welded on the inwall 79 of housing 72.
One face down bonding of mesh screen portion 80 is connected on the terminal 74a edge part of refrigerant inflow pipe 74, and opposite side is used to discharge gaseous state or liquid refrigerants.
With reference to the accompanying drawings 2,3, the gas-liquid separator operation principle of present embodiment air-conditioner is described.
At first, compressor 50 carries out work, and refrigerant circulates under the effect of compressor 50.At this moment, in the refrigerant inflow gas-liquid separator 70 that evaporimeter is discharged.Gaseous coolant flows to compressor 50 in the refrigerant of inflow gas-liquid separator 70.
Here, the refrigerant moving process to gas-liquid separator 70 is described in more details.
The gaseous state or the liquid refrigerants that flow out evaporimeter flow into housing 72 inside by refrigerant inflow pipe 74.At this moment, refrigerant flows into by the terminal 74a of refrigerant inflow pipe 74.
Liquid refrigerants does not splash to the next door under the effect of mesh screen portion 80, but drops onto the downside of housing 72 along mesh screen portion 80.Gaseous coolant is stored in housing 72 inside by the mesh of mesh screen portion 80.
Afterwards, because the pressure differential in the housing 72, gaseous coolant flows into refrigerant discharge pipe 76, flows to compressor 50.
Here, because the terminal 76a of refrigerant discharge pipe 76 is higher than the terminal 74a of refrigerant inflow pipe 74, therefore have only gaseous coolant to flow into refrigerant discharge pipe 76.Drop by between refrigerant discharge pipe 76 terminal 76a and the refrigerant inflow pipe 74 terminal 74a can prevent that liquid refrigerants from flowing directly into refrigerant discharge pipe 76.
Though diagram not, even the end of refrigerant discharge pipe is lower than refrigerant inflow pipe end, as long as the end of mesh screen portion is lower than or etc. be higher than the end of refrigerant discharge pipe, can prevent that then liquid refrigerants from flowing directly into the refrigerant discharge pipe.
In addition, the terminal 76a of several refrigerant discharge pipes 76 is fixed on the inwall of housing 72.When therefore gas-liquid separator 70 bears external impact, can prevent that refrigerant discharge pipe 76 terminal 76a are subjected to displacement.
