Fig. 1 is the refrigeration cyclic graph that possesses the air conditioner 100 of the related reservoir 10 of embodiment 1 of the present utility model, and Fig. 2 is the cutaway view of the related reservoir 10 of embodiment 1 of the present utility model
As shown in Figure 1, air conditioner 100 possesses reservoir 10, compressor 20, cross valve 30, condenser 40, expansion valve 50, liquid pipe arrangement 60, evaporimeter 70 and gas pipe arrangement 80.For example, when cooling operation, the cold-producing medium of discharging from compressor 20 enters condenser 40 through cross valve 30 and carries out cooling, by expansion valve 50, reduced pressure, through liquid pipe arrangement 60, by evaporimeter 70, evaporated, and then successively through gas pipe arrangement 80, cross valve 30, reservoir 10, turn back to compressor 20.
As shown in Figure 2, reservoir 10 possesses: closed container 1; By the inflow pipe 11 importing in from evaporimeter 70 cold-producing medium out to closed container; And the effuser 12 of the U font that the cold-producing medium in closed container 1 is supplied with to compressor 20.At effuser 12, with order highly from low to high, be formed with successively spill port 13a, 13b, 13c.
Spill port 13a is positioned at the liquid cryogen region that is full of liquid refrigerant and refrigerator oil, and spill port 13b, 13c are positioned at the gas refrigerant region of gassy cold-producing medium.The aperture of spill port 13b is identical with the aperture of spill port 13c, and the aperture of the aperture ratio spill port 13a of spill port 13b, 13c is large.Suction pipe 14b, 14c that one end arrives liquid cryogen region opening are connected with spill port 13b, 13c respectively.The height and position of the lower end of suction pipe 14b, 14c is for example identical with the height of spill port 13a, illustrates the shape of spill port 13b and spill port 13c in Fig. 2, but reality suction pipe 14b, 14c are connected with spill port 13b, 13c respectively as described above.
In addition, in the following description, sometimes the spill port that is formed at effuser 12 is referred to as to spill port 13.In addition, in the following description, sometimes the suction pipe being connected with effuser 12 is referred to as to suction pipe 14.
Next, the action of the reservoir 10 of present embodiment 1 is described.
The cold-producing medium importing in closed container 1 from inflow pipe 11 is separated into liquid refrigerant and the gas refrigerant that contains refrigerator oil, and the liquid refrigerant that contains refrigerator oil is stored in the bottom of closed container 1, and gas refrigerant is stored in the top of closed container 1.
Like this, at the liquid refrigerant that contains refrigerator oil and gas refrigerant, be stored under the state of inside of closed container 1, if the operating frequency of compressor 20 uprises, in the circulating mass of refrigerant increase of effuser 12 interior circulations, the dynamic pressure in effuser 12 increases static pressure minimizing.Therefore, from suction pipe 14, the recirculating oil quantity in effuser 12 (the liquid refrigerant amount of returning) increases.
On the other hand, at the liquid refrigerant that contains refrigerator oil and gas refrigerant, be stored under the state of inside of closed container 1, if the operating frequency step-down of compressor 20, in the circulating mass of refrigerant minimizing of effuser 12 interior circulations, the reduction of the static pressure in effuser 12 tails off.Therefore, can not guarantee that liquid refrigerant (refrigerator oil) is at the required potential energy of the interior circulation of suction pipe 14 and pipe friction energy completely, liquid refrigerant (refrigerator oil) is difficult to the inside of inflow and outflow pipe 12.
