Shown in seeing figures.1.and.2, housing 10, cylinder assembly 20 and liquid-storage container 40 can be comprised according to the compressor 100 of the air-conditioning system of the embodiment of the present invention.Refrigeration agent in compressor 100 is difluoromethane, i.e. R32.
Cylinder assembly 20 is located in housing 10, limits compression chamber 21 in cylinder assembly 20.Liquid-storage container 40 comprises shell 41 and outer pipe 42, and outer pipe 42 has two ends, is respectively outward opening end 422 and inner opening end 421.The outward opening end 422 of outer pipe 42 to be positioned at outside shell 41 and to be communicated with compression chamber 21, and the inner opening end 421 of outer pipe 42 is positioned at shell 41.
Capacity due to liquid-storage container 40 relates to its problem holding how many liquid refrigerants.When in air-conditioning system, the filling quantity of refrigeration agent has lacked, so the capacity of liquid-storage container 40 also needs to make to optimize and revise.In liquid-storage container 40, the liquid level height of liquid refrigerant can not exceed the horizontal plane at inner opening end 421 place of outer pipe 42.The inner space that shell 41 surrounds can not all for storing, and wherein only segment space plays conclusive effect.This segment space is the actual volume of liquid-storage container 40.
Specifically, horizontal plane and the volume being positioned at the space that the shell 41 below this horizontal plane surrounds at inner opening end 421 place are the actual volume A of liquid-storage container 40.That is, the actual volume A of liquid-storage container 40 is through horizontal plane and the volume being positioned at the space that the shell 41 below this horizontal plane surrounds of inner opening end 421.Suppose that the filling quantity of the refrigeration agent of air-conditioning system is R.
Inventor finds through research, and A and R meets relation: A=R × m.Wherein, m is coefficient, 0.25≤m≤0.72.When the structure of liquid-storage container 40 meets this relation, liquid-storage container 40 can make liquid refrigerant transform in time to gaseous refrigerant, avoids liquid refrigerant to enter compression chamber 21, ensures the ride quality of compressor 100.
Here, the filling quantity R of refrigeration agent the concrete condition of basis can carry out value, such as, in some embodiments of the invention, and 120g≤R≤5500g.When the value of R and m is determined, namely the actual volume A of compressor 100 can determine.Satisfactory liquid-storage container 40 can be manufactured according to this actual volume A.
According to the compressor 100 of the embodiment of the present invention, the actual volume of liquid-storage container 40 can be determined according to the relation determined, liquid-storage container 40 not only can ensure the normal storage of liquid refrigerant, and can make liquid refrigerant before flowing out liquid-storage container 40, be converted into the refrigeration agent of gaseous state in time, avoid liquid refrigeration agent to enter into compression chamber 21 from outer pipe 42, avoid liquid refrigeration agent to cause damage to compressor 100, compressor 100 is safe and reliable to operation, favorable working performance, long service life.

Under some operating mode (such as worst hot case), when liquid-storage container 40 inside does not exist liquid refrigerant, what this space stored is lubricant oil; (such as worst cold case under some operating mode, deposition promoter operating mode), when there is liquid refrigerant and lubricant oil in liquid-storage container 40 inside simultaneously, due to below 40 DEG C time, liquid refrigerant is than lubricant oil weight, therefore according to the difference of amount of liquid refrigerant, what this space stored can be refrigeration agent, also can contain refrigeration agent and lubricant oil simultaneously.When this space store be refrigeration agent or lubricant oil time, both do not participate in the circulation of refrigeration system, therefore can be described as and be wasted.
Therefore, when the filling quantity of refrigeration agent in air-conditioning system and the oil sealing amount of compressor 100 have adjusted, the volume V in this space also needs to optimize and revise.Inventor finds through research, should meet following relationship: wherein V/L≤0.2 between the volume V in this space and the oil sealing amount L of compressor 100.When the structure of liquid-storage container 40 meets this relation, lubricant oil in liquid-storage container 40 can by spill port 423 oil return in time, reduce the hold-up of lubricant oil in liquid-storage container 40, improve the utilization ratio of lubricant oil, also can ensure that liquid refrigerant gasifies in time simultaneously, improve compressor 100 reliability of operation.
Here, the oil sealing amount L of compressor 100 concrete condition of basis can carry out value, such as, in some embodiments of the invention, and 80ml≤L≤1600ml.When the value of L is determined, namely the volume V in this space can determine.The greasy property meeting the compressor 100 of this relation is good, the efficiengy-increasing of compressor 100, and energy consumption reduces.
