Embodiment
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
The compressor 100 according to the embodiment of the present invention is described in detail below in conjunction with accompanying drawing.
Shown in Fig. 6, housing 10 and cylinder assembly 20 can be comprised according to the compressor 100 of the embodiment of the present invention.Cylinder assembly 20 can be located in housing 10.Cylinder assembly 20 has compression chamber 21 and air intake passage 22, and air intake passage 22 is communicated with compression chamber 21, and refrigeration agent can be drawn in compression chamber 21 by air intake passage 22.Wherein, the refrigeration agent that compressor 100 adopts is difluoromethane, i.e. R32.
Present inventor finds through research, and under identical refrigerating capacity, when adopting the refrigeration agent of R32, the flow-rate ratio refrigeration agent in the past of refrigeration agent is much smaller, and the flow of refrigeration agent is relevant with the discharge volume of compressor 100.Therefore, refrigeration agent enters between the cross-section area of the air intake passage 22 of compression chamber 21 processes and the discharge volume of compressor 100 and should meet certain relation.
Because the cross-section area of air intake passage 22 is along the flow direction of refrigeration agent being change, now, the flow of refrigeration agent then depends primarily on the minimum position of the cross-section area of air intake passage 22.Therefore, certain relation should be met between the smallest cross-section area of air intake passage 22 and the discharge volume of compressor 100.
For convenience of describing, suppose that the discharge volume of compressor 100 is D.Suppose that the smallest cross-section area of air intake passage 22 on the flow direction of refrigeration agent is S1.That is, on the flow direction of the refrigeration agent in air intake passage 22, the smallest cross-section area of this air intake passage 22 is S1.Wherein, the flow direction of refrigeration agent is the bearing of trend of air intake passage 22 usually.In addition, for convenience of describing, the smallest cross-section area of air intake passage 22 described below all refers to the smallest cross-section area on the flow direction of air intake passage 22 refrigeration agent therein.
Inventor draws through research, and S1 and D meets relation: y=D × ρ s/S1.Wherein, y is inspiratory flow coefficient, 0.12g/cm
2≤ y≤0.45g/cm
2.ρ s is under the pressure (absolute pressure) of 1.1MPa, at the temperature of 18 DEG C, the density of R32 cryogen gaseous, ρ s=0.028g/cm
3.
Here, the discharge volume D of compressor 100 can carry out value as the case may be, such as, in some embodiments of the invention, and 3.0cm
3≤ D≤95cm
3.When the value of D and y is determined, namely the smallest cross-section area S1 of air intake passage 22 can determine.The gettering efficiency meeting the compressor 100 of this relation is better, the efficiengy-increasing of compressor 100.
According to the compressor 100 of the embodiment of the present invention, certain relation is met by making the smallest cross-section area of air intake passage 22, make the smallest cross-section area of air intake passage 22 moderate, can not be excessive, also can not be too small, adopt the inhalation resistance of the compressor 100 of R32 little, air-breathing is moderate, and gettering efficiency improves, compressor 100 low in energy consumption, operational efficiency improves, and compressor 100 uses safety and reliability.
As shown in Figures 3 to 5, air intake passage 22 can comprise the first inspiratory limb 221 and the second inspiratory limb 222, second inspiratory limb 222 is communicated with the first inspiratory limb 221.The outlet of the second inspiratory limb 222 is towards compression chamber 21.That is, one end away from the first inspiratory limb 221 of the second inspiratory limb 222 is communicated with compression chamber 21, arranges away from compression chamber 21 compared to the second inspiratory limb 222, first inspiratory limb 221.Refrigeration agent first through the first inspiratory limb 221, then through the second inspiratory limb 222, finally enters into compression chamber 21.
Wherein, the smallest cross-section area of the second inspiratory limb 222 is S1.That is, the actual inspiratory limb depended near compression chamber 21 of the flowing of refrigeration agent in air intake passage 22.Because refrigeration agent flow velocity when flowing through the smallest cross-sectional place of the second inspiratory limb 222 is relatively very fast, make refrigeration agent be easier to be inhaled in compression chamber 21, the pumping property of compressor 100 is good.
Be understandable that, the shape of the second inspiratory limb 222 can be formed as multiple.Such as, as shown in Figure 3, according to some embodiments of the present invention, on the flow direction of refrigeration agent, the cross-section area of the second inspiratory limb 222 can be constant.That is, the cross-section area of the second inspiratory limb 222 cutting is at an arbitrary position S1, and this value remains unchanged.Wherein, the flow direction of refrigeration agent is the axis of the second inspiratory limb 222, i.e. direction shown in dotted lines in Figure 3.
Certainly, the shape of the second inspiratory limb 222 is not limited thereto, and alternatively, the cross-section area of the second inspiratory limb 222 can reduce gradually along the flow direction of refrigeration agent, also can increase gradually.Now, the smallest cross-section area S1 of the second inspiratory limb 222 is then the cross-section area of wherein one end of the second inspiratory limb 222.Such as, as shown in Figure 4, on the flow direction of refrigeration agent, the cross-section area of the second inspiratory limb 222 increases gradually.Now, the smallest cross-section area S1 of the second inspiratory limb 222 is the cross-section area of one end away from compression chamber 21 of the second inspiratory limb 222.
In preferred embodiments more of the present invention, the second inspiratory limb 222 is formed as cylindrical.That is, the second inspiratory limb 222 extends straight, and the cross-section area of the second inspiratory limb 222 is formed as circular, and is remaining unchanged along this cross-section area on the flow direction of refrigeration agent.Thus, the flow resistance of refrigeration agent is less, and flow more smooth and easy and not easily turbulent flow occur, the air suction and noise of compressor 100 is little.
Preferably, the first inspiratory limb 221 and the second inspiratory limb 222 are coaxially arranged.That is, the central axis of the first inspiratory limb 221 and the central axis of the second inspiratory limb 222 are located along the same line.Thus, can roughly linearly flow in the process of refrigeration agent flowing in compression chamber 21, the flowing of refrigeration agent is more smooth and easy and not easily turbulent flow occurs, the inhalation resistance of compression chamber 21 is little, refrigeration agent more easily enters compression chamber 21, and the pumping property of compressor 100 is good, and air suction and noise is less.
Be understandable that, the first inspiratory limb 221 can directly be communicated with the second inspiratory limb 222, also can indirect communication.Such as, in the embodiment shown in Fig. 3 and Fig. 4, the first inspiratory limb 221 is with the second inspiratory limb 222 and is directly communicated with.Again such as, in the embodiment shown in fig. 5, the first inspiratory limb 221 and the second inspiratory limb 222 indirect communication.Specifically, air intake passage 22 can also comprise the 3rd inspiratory limb the 223, three inspiratory limb 223 between the first inspiratory limb 221 and the first inspiratory limb 221.
That is, the first inspiratory limb 221 is not directly connected with the second inspiratory limb 222, but is connected by the second inspiratory limb 222 indirect transition.Refrigeration agent successively through the first inspiratory limb 221, the 3rd inspiratory limb 223 and the second inspiratory limb 222, can enter into compression chamber 21.Due to, the 3rd inspiratory limb 223 plays the effect of connection first inspiratory limb 221 and the second inspiratory limb 222, and therefore, in reality manufactures, the length of the 3rd inspiratory limb 223 can be very short.
Wherein, on the flow direction of refrigeration agent, the shaft shoulder shape structure that can be diminished gradually by cross-section area between two adjacent inspiratory limb carries out transition.Thus, be not only convenient to manufacture, and refrigeration agent can be made to flow steadily during transition flow between inspiratory limb, not easily turbulent flow occurs.
In addition, as shown in Figure 6, on the flow direction of refrigeration agent, the cross-section area of air intake passage 22 can be constant.In other words, when air intake passage 22 is made up of multiple inspiratory limb such as the first inspiratory limb 221, second inspiratory limb 222 and the 3rd inspiratory limb 223, multiple inspiratory limb is all identical along the cross-section area on the flow direction of refrigeration agent, and the smallest cross-section area S1 of air intake passage 22 is the cross-section area of any position of air intake passage 22.Thus, refrigeration agent flows more steady in air intake passage 22, and not easily turbulent flow occurs, compressor 100 inspiratory effects is good.
As shown in Figure 1, cylinder assembly 20 can comprise a cylinder 201, and air intake passage 22 can be located on cylinder 201.Certainly, the structure of cylinder assembly 20 is not limited only to this, and such as, cylinder assembly 20 can comprise cylinder 201 and bearing 202, and bearing 202 can be located at upper end and/or the lower end of cylinder 201.Such as, when bearing 202 is one, this bearing 202 can also can for being located at the lower bearing of cylinder 201 lower end for the upper bearing (metal) being located at cylinder 201 upper end; When bearing 202 is two, two bearings 202 can be respectively upper bearing (metal) and lower bearing.
Wherein, air intake passage 22 can be located on bearing 202 at least partially.That is, air intake passage 22 can be located on bearing 202 completely, also can partly be located on bearing 202.When air intake passage 22 is located on bearing 202 completely, the opening of air intake passage 22 is directly communicated with compression chamber 21.When air intake passage 22 part is located on bearing 202, another part of air intake passage 22 still can be located on cylinder 201.Wherein, compression chamber 21 can directly directly be communicated with the air intake passage 22 be positioned on bearing 202, and also directly can be communicated with the air intake passage 22 be positioned on cylinder 201, this can be arranged as the case may be.
Alternatively, in unshowned embodiments more of the present invention, cylinder assembly 20 can comprise two cylinders 201.That is, can be duplex cylinder compressor 100 according to the compressor 100 of the embodiment of the present invention.Be provided with central diaphragm between two cylinders 201, air intake passage 22 can be located on central diaphragm at least partially.That is, air intake passage 22 can all be located on central diaphragm, also can partly be located on central diaphragm.
When air intake passage 22 is located on central diaphragm completely, the compression chamber 21 of two cylinders 201 directly can be communicated with the opening of air intake passage 22 respectively.When air intake passage 22 part is located on central diaphragm, another part of air intake passage 22 can be located on cylinder 201, and when cylinder assembly 20 also has bearing 202, another part of air intake passage 22 also can be located on bearing 202.Wherein, compression chamber 21 can directly directly be communicated with the air intake passage 22 be positioned on central diaphragm, and also directly can be communicated with the air intake passage 22 be positioned on cylinder 201 or bearing 202, this can be arranged as the case may be.
