Description

Off-premises station with air regulator of fuel feed pump switching function
Technical field
The present invention relates to a kind of off-premises station of air regulator, particularly relate to a kind of off-premises station that fuel feed pump opens and closes the air regulator of function that has that can suppress greenhouse ability drop and the phenomenon of using consumption electric power to increase by uniform fuel feeding operation.
Background technology
See also Fig. 1, shown in Figure 2, Fig. 1 is the structural representation of the off-premises station of existing conventional air adjuster, and Fig. 2 is the fuel feed pump connection status schematic diagram of Fig. 1 compressor.As shown in the figure, this outdoor unit of air conditioner, its be by a pair of the 1st compressor 11 of compressed refrigerant and the 2nd compressor 21, the four-way valve 31 that can change coolant channel, cold-producing medium carry out heat exchange outdoor heat exchanger 33, provide the public accumulator 35 of gaseous state cold-producing medium to be constituted to the 1st compressor 11 and the 2nd compressor 21.
At the 1st compressor 11 and above the 2nd compressor 21, each forms and is provided with the discharge pipe 15,25 that can extrude compressed refrigerant; And,, be provided with the suction line 16,26 that can suck cold-producing medium from public accumulator at the downside of discharge pipe 15,25 along above-below direction.
Extrude part at the 1st compressor 11 and the 2nd compressor, be provided with the lubricant separator 12,22 that separation is discharged with cold-producing medium, be provided with check-valves and partly install in the extrusion of each lubricant separator 12,22 along the flow direction of cold-producing medium.Collaborate mutually from each compressor 11,21 cold-producing mediums that extruded, the interflow part interconnects at the inflow entrance of four-way valve 31.
A flow export of this four-way valve 31 is connected to outdoor heat converter 33, and the another one flow export is connected with public accumulator 35.The refrigerant pipe 37 that another flow export of four-way valve 31 is being connected with the indoor set (not shown) is connected, and each flow export of outdoor heat converter 33 is connected with receiver 39.The refrigerator pipes 37 that is connected with receiver 39 and four-way valve 31 1 ends respectively is provided with service valve 41a, 41b.
In each lubricant separator 12,22, between the 1st compressor 11 and the 2nd compressor 21, be provided with the machine oil backward channel 14,24 that the machine oil that makes separation returns again, and, install and be provided with the fuel feed pump 43 that each inner machine oil is flowed mutually in the bottom of the 1st compressor 11 and the 2nd compressor 21.
According to said structure, after the 1st compressor 11 and the 2nd compressor 21 brought into operation, the cold-producing medium that each compressor 11,21 compression extrudes circulated in kind of refrigeration cycle and finally flow into public accumulator 35 inside.In the inside of public accumulator 35, according to the difference of proportion, the cold-producing medium of gaseous state is arranged at top, the bottom organic oil.The cold-producing medium in field, top is drawn in the corresponding compressor 11,21 by suction line 16,26, and the machine oil of bottom then turns back in each compressor 11,21 by the machine oil return aperture (not shown) that formation is arranged in the suction line 16,26.
In addition, if two 11,21 on compressors exist when having only an operation in the difference of capacity or two compressors 11,21, machine oil can be partial to the compressor of the big or long-time running of capacity, and makes the phenomenon of another compressor generator shortage of oil.
Through after the certain hour, because the machine oil deficiency that the compressor oil deflection takes place is closed under the situation of any one machine, move another one in the 1st compressor 11 and the 2nd compressor 21 in order to prevent.Like this, the machine oil in the compressor out of service 11,21 flow to compressor inside in the running by fuel feed pump 43.Then, close operating compressor, start the compressor stop, therefore make machine oil from a relatively rich effluent to a deficient relatively side, thereby make machine oil keep state relatively uniformly.
But, in existing traditional outdoor unit of air conditioner, because fuel feed pump 43 is in open state all the time, if therefore have the difference of capacity and the relatively large compressor of capacity moved between two compressors 11,21, to add heavy engine oil and lay particular stress on phenomenon, thereby fuel feeding is shortened service cycle relatively, and frequent equal oil operation causes guaranteeing cold-room and greenhouse ability, and frequent starting compressor 11,21 consumption that also will increase electric power.
This shows that the off-premises station of above-mentioned existing air regulator still has many defectives, and demands urgently further being improved.For the defective of the off-premises station that solves existing air regulator, relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly, but does not see always that for a long time suitable design finished by development, and this obviously is the problem that the anxious desire of relevant dealer solves.
Because the existing defective of off-premises station of above-mentioned existing air regulator, the inventor is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge thereof, actively studied innovation, in the hope of founding a kind of off-premises station that fuel feed pump opens and closes the air regulator of function that has of new structure, can improve the off-premises station of existing air regulator, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.
Summary of the invention
